Arthroscopically assisted pectoralis minor transfer for anterosuperior massive rotator cuff tear with irreparable subscapularis tears leads to significant improvement in pain and function at short-term follow-up

PurposeThe purpose of this study was to report the results of an arthroscopically assisted pectoralis minor transfer with an expanded indication to include Lafosse type 4 cases. In addition, prognostic factors for pectoralis minor transfer, including the Lafosse classification, were explored. MethodsOutcomes of arthroscopically assisted pectoralis minor tendon transfer for anterosuperior massive rotator cuff tear with irreparable subscapularis tears with a minimum follow-up of 24 months were retrospectively reviewed. Severe pseudoparesis with flexion of less than 30° was not indicated.All patients were evaluated preoperatively and postoperatively using a modified University of California Los Angeles (UCLA) score, active range of motion, and the visual analog pain scale (pain-VAS). Multiple regression models were used to determine predictors for UCLA score and elevation. ResultsSeventy-four consecutive patients (mean, 69.4 years; 65, male) were evaluated. The mean UCLA score increased from 15.3 preoperatively to 30.9 postoperatively (P < 0.001). The mean active elevation increased from 104° preoperatively to 148° postoperatively (P < 0.001). The mean active external rotation increased from 47° preoperatively to 57° postoperatively (P < 0.001). The pain-VAS improved from 62 to 11 mm postoperatively (P < 0.001). There were no serious complications, but one was revised with reverse shoulder due to ongoing pain. In multiple regression analysis, the positive predictors of UCLA and elevation were the preoperative external rotation angle (P = 0.0028) and elevation angle (P = 0. 00067), respectively. Lafosse classification was not a significant factor. ConclusionsArthroscopically assisted pectoralis minor transfer led to significant improvement in overall shoulder pain and function. Better preoperative range of motions was a significant predictor of better clinical outcomes; Lafosse classification was not significant as a prognostic factor.

Biological Patch in the Repair of Rotator Cuff Tears: Functional and Clinical Evaluation of Twenty-Three Cases with a Mean Follow-Up of Six Years.

Background: Rotator cuff (RC) repair leads to less than optimal results when dealing with massive lesions, so the use of scaffolds as biological support has been proposed to improve RC repair site biology. The present study aims to evaluate the clinical and radiographical outcomes of a series of patients suffering from massive or irreparable RC tears treated with patch (porcine or human scaffolds) repair (augmentation or bridging). Methods: Twenty-three patients with a minimum follow-up of 24 months were subjectively, clinically, and radiographically assessed before and after surgery. Three different patient-related outcome measurements (PROMs) (American Shoulder and Elbow Surgeons score, Constant score, visual analog scale) were used for the subjective and clinical evaluation, while plain radiographs and magnetic resonance imaging where employed for radiographical follow-up. Results: Regardless of the technique (augmentation or bridging) or type of scaffold (porcine or human) employed, at follow-up, all patients experienced a statistically significant improvement in all PROMs and clinically. Conclusions: Patch repair represents a valid salvage procedure in massive or irreparable RC tears, improving the quality of life and eventually delaying the need for prosthetic replacement.

Muscle Advancement During Arthroscopic Rotator Cuff Repair as a Treatment Option for Irreparable Rotator Cuff Tears.

The management of irreparable rotator cuff tears presents a surgical dilemma. However, supraspinatus muscle advancement (MA) could be used to convert irreparable to reparable tears without requiring a graft. To compare the outcomes of patients with an irreparable tear who underwent rotator cuff repair with MA with those with a reparable large to massive cuff tear who underwent rotator cuff repair. Cohort study; Level of evidence, 3. We enrolled 62 patients who underwent rotator cuff repair for a large to massive tear between January 2020 and May 2022. Among them, 29 patients underwent an MA procedure due to an inability to repair despite releases (MA group), whereas the other 33 patients did not require the procedure (NMA group). At 1 year postoperatively, follow-up assessments including magnetic resonance imaging were performed to evaluate group outcomes. Despite there being more revision surgery cases and a poorer potential for cuff healing in the MA group, the retear rates in the MA and NMA groups were similar (31.0% vs 21.2%, respectively; P = .401), as were clinical outcomes, including the visual analog scale for pain (2.9 vs 1.9; P = .076), University of California, Los Angeles (27.0 vs 29.1; P = .185), Constant (70.1 vs 74.9; P = .063), and American Shoulder and Elbow Surgeons (74.5 vs 81.8; P = .168) scores. Postoperative muscle power during forward elevation was weaker in the MA group than in the NMA group (35.1 vs 45.8 N; P = .052), but external rotation power was comparable (49.3 vs 59.0 N; P = .121). Progress in fatty degeneration of the supraspinatus was not significantly different in the 2 groups (P = .43), although the MA group showed a nonsignificant decrease in supraspinatus atrophy (P = .092) due to the lateral shift produced by the procedure. The MA procedure for irreparable tears produced outcomes comparable with reparable tears, offering a valuable perspective on the efficiency of the procedure. The comparable but relatively high retear rates emphasize the need for further studies to compare with other treatment options for irreparable tears.

Tendon transfers for the management of irreparable subscapularis tears.

Rotator cuff pathology is the main cause of shoulder pain and dysfunction in older adults. When a rotator cuff tear involves the subscapularis tendon, the symptoms are usually more severe and the prognosis after surgery must be guarded. Isolated subscapularis tears represent 18% of all rotator cuff tears and arthroscopic repair is a good alternative primary treatment. However, when the tendon is deemed irreparable, tendon transfers are the only option for younger or high-functioning patients. The aim of this review is to describe the indications, biomechanical principles, and outcomes which have been reported for tendon transfers, which are available for the treatment of irreparable subscapularis tears. The best tendon to be transferred remains controversial. Pectoralis major transfer was described more than 30 years ago to treat patients with failed surgery for instability of the shoulder. It has subsequently been used extensively to manage irreparable subscapularis tendon tears in many clinical settings. Although pectoralis major reproduces the position and orientation of the subscapularis in the coronal plane, its position in the axial plane - anterior to the rib cage - is clearly different and does not allow it to function as an ideal transfer. Consistent relief of pain and moderate recovery of strength and function have been reported following the use of this transfer. In an attempt to improve on these results, latissimus dorsi tendon transfer was proposed as an alternative and the technique has evolved from an open to an arthroscopic procedure. Satisfactory relief of pain and improvements in functional shoulder scores have recently been reported following its use. Both pectoralis minor and upper trapezius transfers have also been used in these patients, but the outcomes that have been reported do not support their widespread use.

Long-term outcomes of anterior latissimus dorsi tendon transfer for irreparable subscapularis tears.

Favourable short-term outcomes have been reported following latissimus dorsi tendon transfer for patients with an irreparable subscapularis (SSC) tendon tear. The aim of this study was to investigate the long-term outcomes of this transfer in these patients. This was a retrospective study involving 30 patients with an irreparable SSC tear and those with a SSC tear combined with a reparable supraspinatus tear, who underwent a latissimus dorsi tendon transfer. Clinical scores and active range of motion (aROM), SSC-specific physical examination and the rate of return to work were assessed. Radiological assessment included recording the acromiohumeral distance (AHD), the Hamada grade of cuff tear arthropathy and the integrity of the transferred tendon. Statistical analysis compared preoperative, short-term (two years), and final follow-up at a mean of 8.7 years (7 to 10). There were significant improvements in clinical scores, in the range and strength of internal rotation and aROM compared with the preoperative values in the 26 patients (87%) who were available for long-term follow-up. These improvements were maintained between short- and long-term follow-ups. Although there was a decreased mean AHD of 7.3 mm (SD 1.5) and an increased mean Hamada grade of 1.7 (SD 0.5) at final follow-up, the rate of progression of cuff tear arthropathy remained low-grade. Comparison between the isolated SSC and combined SSC and reparable supraspinatus tear groups showed no significant differences. At final follow-up, one patient (3.8%) had undergone revision surgery to a reverse shoulder arthroplasty (RSA). No neurological complications were associated with the procedure. Latissimus dorsi transfer for an irreparable SSC tendon tear resulted in a significant clinical improvement, particularly in pain, range and strength of internal rotation and aROM, which were maintained over a mean of 8.7 years following surgery. Given that this was a long-term outcome study, there was a low-grade progression in the rate of cuff tear arthropathy. Thus, the long-term clinical efficacy of latissimus dorsi tendon transfer in patients with irreparable SSC was confirmed as a joint-preserving procedure for these patients, suggesting it as an effective alternative to RSA in young, active patients without degenerative changes of the glenohumeral joint.

The Trillat procedure: the man and the technique revisited through the lens of arthroscopy.

The Trillat procedure, initially described by Albert Trillat, is historically one of the first techniques for addressing recurrent anterior shoulder instability, incorporating fascinating biomechanical mechanisms. After lowering, medializing, and fixing the coracoid process to the glenoid neck, the subcoracoid space is reduced, the subscapularis lowered, and its line of pull changed, accentuating the function of the subscapularis as a humeral head depressor centering the glenohumeral joint. Furthermore, the conjoint tendon creates a 'seatbelt' effect, preventing anteroinferior humeral head dislocation. Even though contemporary preferences lean towards arthroscopic Bankart repair with optional remplissage, bone augmentation, and the Latarjet procedure, enduring surgical indications remain valid for the Trillat procedure, which offers joint preservation and superior outcomes in two distinct scenarios: (i) older patients with massive irreparable cuff tears and anterior recurrent instability with an intact subscapularis tendon regardless of the extent of glenoid bone loss; (ii) younger patients with instability associated shoulder joint capsule hyperlaxity without concomitant injuries (glenoid bone loss, large Hill-Sachs lesion). Complications associated with the Trillat procedure include recurrent anterior instability, potential overtightening of the coracoid, leading to pain and a significant reduction in range of motion, risk of subcoracoid impingement, and restriction of external rotation by up to 10°, a limitation that is generally well-tolerated. The Trillat procedure may be an effective alternative technique for specific indications and should remain part of the surgical armamentarium for addressing anterior shoulder instability.

Shoulder balloon spacer for massive irreparable rotator cuff tears results in significant improvements.

The aim of the present study was to assess the effectiveness of balloon implantation in patients with irreparable supraspinatus tears alone or in combination withother rotator cuff (RC) tendon tearsand the effect of several covariables, such as age, gender, status of the long head biceps, with or without tendon repair and regardless the number of tendon involved. Patients enrolled from 'San Carlo' Hospital of Potenza (Italy, IT), from January 2012 to September 2014, underwent arthroscopic implantation of shoulder balloon by a single surgeon, and followed for 3 years. The American Shoulder and Elbow Surgeons (ASES) and Constant score (CS) were administered pre-, post-operatively at 12 months, and then annually. Patients were classified on the basis of the number of tendons involved in the tears and treatment performed, considering the reparability of the tendons themselves. Gleno-humeral joint osteoarthrosis (OA) was evaluated through shoulder radiographs and classified according to the Samilson-Prieto classification, at the first examination and at the final follow-up. Statistical improvements were evaluated using a variance model (least-squares means)and a T distribution test for the evaluation between different treatment groups. A total of 61 procedures were performed, and eight patients were lost during follow-up. The mean baseline CS was 30.2 ± 15.4 with statistically significant improvement, respectively, at 1-, 2- and 3-year follow-up to 69.3 ± 4.2, 74.6 ± 3.6 and 69.7 ± 5.1 respectively. ASES score at baseline was 22.5 ± 10.9, with a statistically significant improvement to 69.7 ± 9.2, 68 ± 17.8 and 71.2 ± 16.6 at 1-, 2- and 3-year follow-up, respectively. Tenotomy or absence of long head biceps at presentation did not influence results (n.s.), with no difference according to gender and age. At final follow-up, 24 patients (43.9%) showed progression of glenohumeral OA. One patient required secondary surgery for shoulder replacement after 18 months for persistent pain and one patient required implant removal following post-operative laser treatment. Arthroscopic rotator cuff tears repair with subacromial spacer balloon implantation showed statistically significant clinical and functional improvement at 3-year follow-up. Patients treated with combined partial repair and subacromial spacer balloon implantation experienced good results independent of gender, age, type of tear and long-head biceps tendon status. The risks related to this procedure appear to be minimal. Level IV.

Rotator cuff repair: Sleep disturbance significantly improves after arthroscopic tendon repair.

The aim of this study was to quantify sleep quality and define its evolution in patients treated for rotator cuff tears (RCTs) with arthroscopic rotator cuff repair (ARCR) and to understand its correlation with patients' depression and anxiety. The patients were part of the 'ARCR_Pred cohort study', a prospective multicentre cohort of ARCR patients. adult, RCT diagnosed by magnetic resonance imaging, treated by primary ARCR. irreparable tears, revision operations, open or mini-open reconstructions, pregnancy. Subjective sleep quality (prevalence and level of disturbance) was analysed. Psychological characteristics (PROMIS Sf questionnaire) and functional outcomes (Constant and Murley Score and Oxford Shoulder Score) were investigated. A gender-based analysis was performed as well. Patients were evaluated before the operation and prospectively at 6 and 12 months. Of the 973 patients, 611 (62.8%) were men, with the mean age being 57.3 ± 9.4 years (range, 21-84). A high prevalence of sleep disturbances was found before ARCR (88.4%), with 59% of the patients complaining of disturbance every night. Sleep disturbances progressively improved at 6 (37.2%) and 12 months (22.0%). Also, nocturnal pain (frequency of night disturbed by pain) progressively improved from 94.3% to 62.4% and then 37.9%. For depression and anxiety, a statistically significant difference (p < 0.05) was retrieved among every group (undisturbed, occasionallyand always disturbed) at all follow-ups. On the other hand, the post-op improvement led to a decrease in anxiety and depression levels passing from 50.1 and 51.4 points at baseline to 45.0 and 45.4 at 12 months, respectively. Women had statistically worse sleep quality at 6 and 12 months (41% vs. 36% and 27% vs. 19%, respectively) (p < 0.05). RCTs cause a high prevalence of sleep disturbance and nocturnal pain, which progressively resolves after an arthroscopic tendon repair. Women have a higher risk than men of presenting disturbed sleep quality. Level III, prognostic cohort study.

Improved restoration of biomechanical factors using a narrow-box shaped reconstruction compared to a wide one in superior capsular reconstruction for irreparable supraspinatus tendon tears: a biomechanical study using a static shoulder simulator

PurposeTo biomechanically compare superior glenohumeral translation, subacromial contact pressures and area in a box-shape reconstruction using the long head of biceps tendon (LHBT) in an irreparable supraspinatus tendon tear model. MethodsSeven cadaveric shoulders (mean age 61 years; range 32-84 years; SD 22.3) were tested with a custom testing rig used to evaluate superior translation, subacromial contact pressures and areas at 0°, 30° and 60° of glenohumeral abduction. Conditions tested included the native state, a complete tear of the supraspinatus tendon, a wide box-shaped, double-bundle LHBT superior capsular reconstruction (wide BS-SCR), and a narrow box-shaped, double-bundle LHBT superior capsular reconstruction (narrow BS-SCR). ResultsCompared to the wide box-shape SCR, the narrow box-shape SCR had statistically significant lower median contact pressure at 30° and 60°. The subacromial contact area showed a statistically significant difference at 0° (p=0.001) and 30° (p=0.004) for the narrow compared to wide box-shape SCR. At an abduction angle of 0°, the narrow SCR could restore superior translation statistically significant better compared to the wide construct. For all angles, the wide and narrow box-shaped SCR increased the median subacromial distance statistically significantly. The contact areas in 30° and 60° of abduction were higher for all scenarios, both peaking in the intact state in 30° with approximately 600 mm2. ConclusionsIn comparison to a wide box-shape, a narrow box-shape SCR using the LHBT has biomechanical advantages in regard of subacromial contact pressures, the subacromial contact areas as well as the acromiohumeral distance. The width of the reconstruction therefore has direct influence in the success of the technique.

Management of Massive Irreparable Posterosuperior Cuff Tears: A Systematic Review for Clinical &amp; Functional &amp; Radiological Outcomes

Abstract Background The management of massive irreparable cuff tears (MIRCT) remains a highly controversial subject with many possible surgical and non-surgical interventions and no clear evidence regarding the most effective and beneficial intervention. Different management options include: conservative management, partial repair, tendon transfer, superior capsular reconstruction, subacromial spacer insertion, reverse total shoulder arthroplasty (RTSA). Aim of the Work The aim of this systematic review is to compare the various methods of management of posterosuperior cuff tears without arthropathy to reach the most effective and sustainable mode of management. Patients and Methods A randomized controlled trial, non-randomized clinical trials, prospective and retrospective comparative cohort studies and case series. We will exclude cross-sectional studies, case reports and literature not in English. Results There is no high quality evidence on management of MIRCT. There was no Level I or II evidence. We included 69 papers that studied different modalities of management of MIRCT, 31 of level III and the remaining were of level IV evidence. Consequently, it’s still difficult to recommend one method of management over the other regarding the management of irreparable cuff tears. Patient age, demands, expectations, thorough clinical examination, surgeon experience and preference are still a major deciding factor when choosing and appropriate method. Conclusion Due to the unavailability of high-quality clinical studies available for guiding management of irreparable MRCT, it is consequently not possible to recommend for or against any specific treatment strategy. Rather, clinical experience, patient factors, patient expectations, and rotator cuff tear characteristics should guide clinical decision-making. Physical therapy compared to surgical treatments may have inferior outcomes. Standardized data collection, reporting and terminology are key to enhancing the quality of evidence-based medicine.

Short-Term Results after Reversed Total Shoulder Arthroplasty

Abstract Purpose Massive rotator cuff tear, with or without arthritis and proximal humerus fracture non-union or malunion, lead to the loss of center of rotation of shoulder, while anatomical total shoulder arthroplasty does not provide a stable center of rotation, Therefor reversed total shoulder arthroplasty (RTSA) is the suitable method for these indications, as well as in elderly patients with primary glenohumeralosteoarthritis because anatomical total shoulder arthroplasty has the risk of failure either due to loosening of glenoid component or cuff tear. This study aimed to determine the short-term results after RTSA in patients a with massive cuff tear, acute proximal humerus fracture, proximal humerus fracture malunion or non- union, and primary glenohumeralosteoarthritis. Methods This one arm clinical trial (interventional study) conducted in Ain Shams University Hospitals included 16 patients who underwent RTSA. Short-term outcomes included constant score, American Shoulder and Elbow Surgeon (ASES) score, and range of motion (ROM). Patients with rotator cuff arthropathy, massive irreparable cuff tear with or without glenohumeralarthritis, elderly patients with acute complex proximal humerus fracture, malunited or nonunited proximal humerus fracture, and patients with glenohumeralosteoarthritis were included. Patients who were aged &amp;lt;50 years were excluded, as well as patients with axillary nerve injury or deltoid muscle dysfunction. Results This study included 16 patients, including 8 males and 8 females. The mean age was 64.19 years and the duration of follow up-was 1 year postoperatively. Seven Patients with massive irreparable cuff tear were included, of them, 1 had associated anterior shoulder instability and recurrent anterior dislocation, 3 had a four-part proximal humerus fracture, 2 had fracture dislocation, 2 had proximal humerus fracture non –union, 1had neglected dislocation, and 2 had glenohumeralosteoarthritis. Outcomes were followed using constant and ASES scoring systems, and ROM. The global postoperative gain was statistically significant (p &amp;lt; 0.001). Complication in the form of dislocation occurred in one case that had RTSA after fracture non-union. Conclusion Good clinical and functional outcomes were achieved after RTSA, not only for classic massive cuff tear indication, but for other disorders, such as acute proximal humerus fracture, fracture non-union, and primary glenohumeralosteoarthritis. However, the outcomes after irreparable cuff tear were the best among all indications, while fracture non-union had the least improvement in clinical outcomes. Improvements in prosthesis design, surgeon’s experience, and clinical results are necessary to optimize this treatment for many shoulder conditions.

Surgical Management of Massive Irreparable Cuff Tears/Management of Rotator Cuff Disease: Interpositional Graft for Irreparable Posterosuperior Rotator Cuff Tears.

Increasingly, massive irreparable rotator cuff tears present a treatment challenge due to their high re-tear rates. The reparability of such tears depends on factors like tear size, the number of involved tendons, tendon retraction extent, muscular atrophy, fatty infiltration, and the presence or absence of arthritis. There are non-surgical and several surgical treatment options described each with their specific indications, contraindications, pros, and cons. Bridging reconstruction restores the superior rotator cuff tissue and arrests humeral head superior migration. The purpose of his review is to explore the existing literature on interpositional graft mechanics, indications, surgical technique, and clinical outcomes. It aims to understand how these parameters can facilitate the incorporation of bridging reconstruction using interpositional grafts into a surgeon's practice for managing massive irreparable rotator cuff tears. Interpositional grafts for irreparable massive rotator cuff tears can either be auto-, allo-, xenografts, or synthetic material and are best suited for patients who are relatively younger, no glenohumeral arthritis, and minimal to no fatty infiltration and muscle atrophy. Short to medium term outcome studies available report good functional, clinical, and radiological improvements with bridging reconstruction utilizing acellular dermal matrix allograft. Interpositional grafts for management of irreparable posterosuperior cuff tears provides improved clinical and radiological outcomes with minimal complications and thus a viable and valuable surgical technique for a shoulder surgeon's armamentarium.

Short-Term Results after Reverse Total Shoulder Arthroplasty

Abstract Background: The loss of the shoulder’s center of rotation is caused by massive rotator cuff tears, which can occur with or without arthritis and proximal humerus fractures that are nonunion or malunion. Because anatomical total shoulder arthroplasty cannot provide a stable center of rotation, reverse total shoulder arthroplasty (RTSA) is the appropriate procedure for these indications and in older patients who have primary glenohumeral osteoarthritis. Anatomical total shoulder arthroplasty carries a risk of failure because of the loosening of the glenoid component or cuff tear. The purpose of this study was to determine the short-term outcomes following RTSA in patients who had primary glenohumeral osteoarthritis, acute proximal humerus fractures, malunited or nonunited proximal humerus fractures, and massive cuff tears. Materials and Methods: This single-arm clinical trial (interventional study) was done in Ain Shams University Hospitals; 16 patients were included who underwent RTSA. Constant score, American Shoulder and Elbow Surgeon score, Visual Analog Scale score, and range of motion (ROM) were the short-term outcomes. Patients with cuff tear arthropathy, irreparable cuff tear with or without glenohumeral arthritis, elderly patients with unreconstructable proximal humerus fracture, proximal humerus fracture malunion or nonunion, and patients with glenohumeral osteoarthritis were included. Patients under the age of 50, as well as those with deltoid muscle dysfunction or injuries to the axillary nerve, were excluded. Results: There were 16 patients in this study, 8 of whom were male and 8 of whom were female. The follow-up period lasted 2 years following surgery, with a mean age of 64.19 years. The study included 7 patients with irreparable cuff tears one of them had associated anterior shoulder instability and recurrent anterior shoulder dislocation. One patient had a neglected shoulder dislocation, two patients had proximal humerus fracture dislocation, two patients had a nonunited proximal humerus fracture, three patients had unreconstructable proximal humerus fracture, and two had glenohumeral osteoarthritis. Conclusion: Not only did RTSA provide good clinical and functional outcomes for the standard indication of a massive cuff tear, but it also proved beneficial for other disorders such as primary glenohumeral osteoarthritis, nonunited fracture, and acute proximal humerus fracture. Among all indications, irreparable cuff tears yielded the highest results; nonunited fractures displayed the least improvement regarding clinical outcomes. Enhancements in the design of prostheses, the expertise of surgeons, and clinical outcomes are crucial to maximize their effectiveness in treating various shoulder disorders.

Mid- to Long-Term Outcomes in Patients After Hip Arthroscopy With Labral Reconstruction: A Systematic Review.

There is a paucity of aggregate data documenting mid- to long-term outcomes of patients after hip arthroscopy with labral reconstruction. To report mid- to long-term outcomes in patients after undergoing either primary or revision hip arthroscopy with labral reconstruction for the treatment of irreparable labral tears. Systematic review; Level of evidence, 4. A systematic review of the PubMed, Cochrane, and Scopus databases in May 2022 was conducted with the following keywords: "hip arthroscopy,""labral reconstruction,""irreparable,""labrum,""reconstruction,""five-year,""midterm,""5 year,""long-term,""10 year," ten-year," and "femoroacetabular impingement" using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria. Midterm was defined as mean 5-year follow-up, and long-term was defined as mean 10-year or longer follow-up. For each included article, the demographic, radiographic, intraoperative, and surgical variables, as well as patient-reported outcomes (PROs), psychometric thresholds, and secondary surgeries were recorded. Forest plots were created for PROs that were reported in ≥3 studies; heterogeneity was assessed using I2 values. Out of 463 initial articles, 5 studies including 178 hips with primary and 41 hips with revision surgeries were included. One study had an average 5-year follow-up, three studies had a minimum 5-year follow-up and one study had a minimum 10-year follow-up. The most common indications for hip arthroscopy with labral reconstruction were irreparable labral tears. The most common PRO was the modified Harris Hip Score (mHHS), which was reported in all 5 studies. The mean preoperative mHHS ranged from 58.9 to 66, and the mean postoperative mHHS at minimum 5-year follow-up ranged from 80.2 to 89. The preoperative and postoperative mHHSs for the single long-term follow-up study were 60 and 82, respectively. All 5 studies demonstrated significant improvements in reported PROs. All 5 studies reported secondary surgery rates, with 1 study reporting rates at both 5- and 10-year follow-up. Conversion to total hip arthroplasty ranged from 0% to 27%, while overall secondary surgery rates ranged from 0% to 36%. Findings demonstrated that patients undergoing primary and revision hip arthroscopy with labral reconstruction experienced favorable outcomes and high rates of clinical benefit and survivorship at mid- to long-term follow-up.

Effect of glenosphere diameter and lateralization in primary reverse shoulder arthroplasty: a randomized clinical trial

BackgroundWithin reverse total shoulder arthroplasty (RSA), prior studies have suggested that smaller glenosphere diameters may result in higher rates of scapular notching and polyethylene wear, while lateralized glenospheres may allow for better range of motion (ROM); however, supportive data remains limited. Therefore, the purpose of this study was to report the outcomes of a prospective randomized clinical trial comparing 4 different glenosphere configurations based on diameter and lateral offset. MethodsBetween 2016 and 2020, 113 primary RSAs with a diagnosis of either rotator cuff tear arthropathy (n = 48, 42%), irreparable rotator cuff tears (n = 22, 19%), or primary glenohumeral osteoarthritis with subluxation or glenoid bone loss (n = 43, 38%) were enrolled into a blinded prospective randomized clinical trial. The mean age of the patients included in the study was 73 ± 7 (range, 50-89) years, and 58 (51.3%) were males. All procedures were performed by two surgeons utilizing the ReUnion RSA system (Stryker, Mahwah, NJ, USA). Patients were randomized into four possible groups based on the diameter and lateral offset of the glenosphere implanted: 36 mm diameter with 2 mm (n = 34, 30.1%) or 6 mm (n = 28, 24.8%) of lateralization and 40 mm diameter with 2 mm (n = 29, 25.7%) or 6 mm (n = 22, 19.5%) of lateralization. Outcomes collected included pain, active ROM, strength, satisfaction, patient-reported outcome measures (PROMs), complications, reoperations, and revisions. PROMs included the Oxford Shoulder Score, the American Shoulder and Elbow Surgeons, and the quick Disabilities of the Arm, Shoulder and Hand questionnaire. All patients were followed for a minimum of 2 years. ResultsWith the numbers available, glenosphere diameter and lateralization resulted in no differences in pain, ROM, strength, satisfaction, and PROMs at 1 year, 2 years, or final follow-up (All P > .05). However, all 3 complications (10.7% vs. 0% vs. 0% vs. 0%; P = .025) and 2 revision surgeries (7.1% vs. 0% vs. 0% vs. 0%; P = .103) occurred in males, with the 36 + 6 cohort. ConclusionsUsing this particular RSA design, implantation of glenospheres with 36 mm or 40 mm of diameter and 2 mm or 6 mm of sphere lateralization did not translate into significant differences when primary RSA was performed in shoulders with rotator cuff tear arthropathy, irreparable cuff tears, or primary glenohumeral osteoarthritis. However, all observed complications occurred in males with the smallest diameter and lateralized glenosphere.

Double Row Rotator Cuff Repair for Massive Reparable Rotator Cuff Tear

Background: Massive rotator cuff tears, defined as those that involved 2 or more tendons or where the length of the greatest diameter is greater than 5 cm, present a unique surgical challenge as there can be significant scarring, retraction, and poor tissue quality. Furthermore, healing of these tears is less reliable. This video presents our technique for anatomic, double row repair of a massive reparable rotator cuff tear. Indications: Indications for operative intervention include acute traumatic tears, as well as patients with pain and weakness who have failed to respond to conservative management, including physical therapy with confirmed large full thickness rotator cuff tear on advanced imaging. Of note, findings such as glenohumeral osteoarthritis, advanced muscle atrophy (Goutalier III/IV), superior migration of the humeral head &gt;7 mm, and tears larger than 40 mm in length and width are concerning for irreparable tears, and may represent contraindications to surgical repair. Technique Description: The patient is placed in the lateral decubitus position. After diagnostic arthroscopy is performed, a subacromial bursectomy is performed. A radiofrequency probe and arthroscopic shaver are used to perform releases in the subacromial space as well as superior to the glenoid. Preparation of the footprint of the humeral head is then performed to create a good healing surface. The rotator cuff is grasped to confirm tension free mobilization. The medial row anchors are then placed. Once placed, the sutures are incorporated into 2 lateral row anchors in sequential fashion. Subacromial decompression is then performed. Results: Reduced pain and improved shoulder function are the goals of treatment, with sling immobilization lasting for roughly 6 weeks postoperatively prior to initiating strengthening and range of motion protocols. Discussion/Conclusion: Arthroscopic double row repair produces an anatomic and stable reduction of reparable massive rotator cuff tears for patients that have failed conservative management.

Long head of biceps tendon augmentation for massive rotator cuff tears improves clinical results regardless of the number of tendons involved.

Management of massive rotator cuff tears (MRCTs) remains debated, and various arthroscopic and open techniques have been described for their management. Nevertheless, the optimal strategy remains unclear. The present study evaluated the clinical results in patients managed arthroscopically for MRCTs augmented with the long head biceps tendon (LHBT) at a minimum 1-year follow-up, considering different type of tears, demographic data and number of torn tendons. Patients treated in a secondary referral centre from January 2021 to April 2022 were enroled prospectively. Inclusion criteria were pain, inability to fully elevate the affected shoulder, irreparable tears and active and motivated patients. All patients were managed within 2 months from diagnosis in a single centre by the same surgeons. Preoperative shoulder radiographs and magnetic resonance imaging (MRI) were collected, and clinical assessment was also performed using the Numerical analogue scale (NAS), Constant score (CS) American Shoulder and Elbow Surgeons Shoulder Score (ASES). Tissue retraction and tendon fatty infiltration were evaluated using Patte and Fuchs scale, respectively. Clinical assessment was performed using the same scales at 3-6 months and 1-year follow-up. A total of 55 patients (31 female and 24 male) with a mean age of 60 ± 7.1 years were enroled for a mean follow-up of 18.2 ± 4.3 months. The mean preoperative NAS was 7.8 ± 0.6, CS was 20.5 ± 7.6 and ASES was 22.6 ± 9.2, increasing, respectively, to 0.3 ± 0.6, 91.5 ± 6.9 and 94.2 ± 6.7. No adverse side effects (infection, rejection, allergy) were reported during the study period. All patients were evaluated after surgery at 3 and 6 months and 1 year with statistically significant improvement for each score at the first and last follow-up (p < 0.05). The use of LHBT augmentation in patients with MRCTs in appropriately selected patients is safe and effective and can lead to pain relief and acceptable clinical outcomes. Furthermore, its use carries low donor site morbidityand is cost effective. Comparative studies, including randomised controlled trials, with other proposed techniques are needed to confirm these findings. Level IV.

Combined Anterior Latissimus Dorsi and Teres Major Tendon Transfer (aLDTM) for Irreparable Anterosuperior Rotator Cuff Tears.

Transfer of the anterior latissimus dorsi and teres major (LDTM) tendons has demonstrated favorable outcomes in patients with irreparable anterosuperior rotator cuff tears1. The objective of this procedure is to restore internal rotation strength, enhance active range of motion, and provide pain relief while preserving the glenohumeral joint. The incision extended from the coracoid to the inferior border of the pectoralis major tendon, following the deltopectoral interval located laterally to the coracoid. While preserving the pectoralis major tendon, the latissimus dorsi (LD) and teres major (TM) tendons are identified and detached from the humerus without separating the tendons. The LDTM tendons are grasped, and nonabsorbable sutures are placed in a continuous running-locking suture fashion. Traction is applied to the sutures while bluntly releasing the adhesions surrounding the LDTM muscles in order to enable further mobilization and excursion. With the patient's arm positioned in full internal rotation and at 45° of abduction for physiological tensioning, the LDTM tendons are attached 2 cm distal to the lateral edge of the greater tuberosity and lateral to the biceps groove with use of 1 medial anchor and 3 lateral anchors. Arthroscopic partial repair, superior capsular reconstruction, pectoralis major tendon transfer, and isolated LD tendon transfer are potential alternative treatments. In cases in which these options are not feasible or have been unsuccessful, reverse total shoulder arthroplasty can be considered as a treatment option. Arthroscopic partial repair can provide pain relief, but its effectiveness in improving range of motion and muscle strength is limited2,3. Additionally, there is a high risk of retear, with reported rates as high as 52%4. Superior capsular reconstruction is considered a viable treatment, but it is not recommended in cases involving irreparable subscapularis tears5-7. Pectoralis major transfer may lead to less favorable clinical outcomes in cases in which an irreparable subscapularis tear and an irreparable supraspinatus tear are simultaneously present8-10. In cases of irreparable anterosuperior rotator cuff tears, the transfer of the LD tendon alone may not fully restore the superior migration and anterior subluxation of the humeral head.11. Reverse total shoulder arthroplasty may be another option in these cases, but it does not preserve the glenohumeral joint. The procedure involves stabilizing the superior translation of the humeral head by rebalancing the force couple, as the TM tendon exhibits scapulohumeral kinematics similar to the subscapularis tendon. Additionally, the procedure effectively reduces anterior glenohumeral subluxation through the combined effect of the posterior line of pull from the combined LDTM tendons and the scapulohumeral kinematics of the teres minor tendon. Also, by fixing the transferred LDTM tendons just distal to the greater tuberosity, the vector becomes less vertical, thereby preventing axillary nerve impingement and achieving appropriate tendon tensioning. The use of this procedure is supported by a study of 30 patients who were followed for a minimum of 2 years1. Significant improvements were observed in various scoring systems, including the pain VAS (visual analogue scale), Constant, ASES (American Shoulder and Elbow Surgeons), UCLA (University of California-Los Angeles), SANE (Single Assessment Numeric Evaluation), and ADLIR (Activities of Daily Living requiring active Internal Rotation) scores. Importantly, there was no significant progression of cuff tear arthropathy observed during the final follow-up. Additionally, preoperative anterior glenohumeral subluxation (15 of 30 patients) was restored in all patients after LDTM tendon transfer. Careful attention should be paid to the anterior humeral circumflex vessels to prevent bleeding.The radial nerve, passing through the anteroinferior surface of the LDTM tendons, should be carefully identified and protected to avoid iatrogenic injury.To maintain physiologic tension, the patient's arm should be positioned in full internal rotation and 45° of abduction.To avoid axillary nerve impingement, the LDTM tendons should be fixed just distal to the greater tuberosity and lateral to the biceps groove.

Up to date diagnosis and treatment of massive irreparable cuff tears: Results of the survey of the U45 ESSKA Committee.

Irreparable rotator cuff tears are disabling and can severely affect daily life activities, especially when young and active patients are involved. The definition is still debated, and they can have several clinical presentations. The treatment depends on the clinical presentation and the patient'sage. The survey was developed by the ESSKA U45 Committee and was uploaded on the ESSKA website. Fifty-seven questionnaires were returned. Several aspects of the diagnosis and treatment of massive irreparable cuff tears were investigated. Moreover, treatment options for specific clinical scenarios were given for posterior-superior and anterior-superior cuff tears in young and old patients. Fatty degeneration of the muscles was the most common criterion to define an irreparable tear (59.7%). In young patients with external rotation with the arm at side lag, partial repair of the cuff was the most common option (41.8%); in case of external rotation with the arm at side + external rotation at 90° of abduction lag without pseudoparalysis, the most common option was partial repair of the cuff + latissimus dorsi or lower trapezius transfer (39.3%), and in case of external rotation with the arm at side + external rotation at 90° of abduction lag with pseudoparalysis, partial repair of the cuff + latissimus dorsi or lower trapezius transfer was still the most common option (25.5%). The same scenarios in old patients yielded the following results: reverse prosthesis (49.1%), reverse prosthesis (44.6%) and reverse prosthesis ± latissimus dorsi or lower trapezius transfer (44.6%), respectively. The present survey clearly confirms that biological options (partial cuff repairs and tendon transfers) are the reference in the case of young patients with deficient cuffs (both posterior and anterior). Reverse shoulder prosthesis is the most common treatment option in old patients in all clinical scenarios. Level IV.
