Rotator cuff repair with all-suture anchor enhances biomechanical properties and tendon-bone integration in a rabbit model

BackgroundAll-suture anchor (ASA) is a special type of suture anchor. It has been used to repair rotator cuff tears (RCTs). However, mechanical properties and tendon-bone integration at different time postoperatively remains to be unclear. MethodsMechanical testing and water contact angle measurements were conducted for ASA. In vitro biocompatibility was assessed using rat bone marrow stem cells (BMSCs), including live/dead cell staining and Cell Counting Kit-8 assays. ASA was implanted for rotator cuff repair (ASA group) in a New Zealand White rabbit model of RCTs, and a natural rotator cuff was used as a control (natural group). The animals were sacrificed, and tissue samples were harvested for biomechanical, radiographic, and histological analysis at 4, 8, and 12 weeks postoperatively. ResultsASA was hydrophobic and had a strong mechanical property in vitro. The biocompatibility analysis showed that ASA had no effect on the viability of BMSCs. Mechanical testing in vivo revealed that a gradually improved failure load of ASA group was 118.0 ± 22.53N at 12 weeks postoperatively, which was recovered to the natural group. Micro-CT analysis indicated that an initial decrease in BMD and trabecular quality following ASA implantation, with a slight recovery observed at 12 weeks. Additionally, histological analysis showed the tendon-bone interface gradually integrated in the ASA group. A significant increase in tendon-bone interface scores was found from 4 weeks to 12 weeks. Tendon maturing score also improved in the ASA group, and Type I collagen content recovered to 18.58 ± 4.378 % at 12 weeks and no different from that of the natural group. ConclusionRotator cuff repair with ASA in a rabbit model demonstrated the capacity to enhance biomechanical properties and tendon-bone integration.

Surgically Treated Ischial Tuberosity Avulsion Fractures in Adolescents: Risks and Outcomes of 3 Fixation Constructs.

Avulsion fractures of the ischial tuberosity (AFIT) are uncommon injuries that sometimes require operative fixation with screws, suture anchors, or cortical suspensory buttons. This study reviewed a series of surgically managed AFITs at a single institution and compared outcomes among fixation strategies. We hypothesized there would be no difference in outcomes between fixation types. We conducted a retrospective review of all patients treated operatively at a single institution from 2010 to 2022 for AFIT identified by CPT code (27215). We collected patient demographics, injury characteristics, Revised Modified Oxford Bone Score, radiographic measures, fracture classification (type 1-lateral vs. type 2-complete), surgical fixation technique, postoperative complications (Modified Clavien-Dindo-Sink [M-CDS] Complication Classification), and time to return to sport (RTS). Descriptive statistics and univariate analyses were performed. Study criteria identified 16 patients with surgically treated AFITs during the study period. Patients were predominantly male (88%) with a mean age of 14.8±0.8 years. Injured patients most commonly participated in soccer (38%), with the most common mechanism of injury being running/sprinting (50%). The avulsed fracture fragments were a mean of 42.6mm in size, with an average maximal displacement of 21.1mm and predominantly type 1-lateral (75%). Surgical constructs included: screws (4), suture anchors (5), cortical suspensory buttons (6), and combined (1, screw and suture anchor). Postoperative complications occurred in 8 patients (50%) including 7 type 1 and 1 type 3 M-CDS. No statistically significant difference was found between fixation types among the studied outcome variables; however, re-fracture (1 case [M-CDS type 3]) was only observed with a combined (screw and suture anchor) construct. This retrospective cohort study demonstrated that postoperative complications after ORIF for AFIT were not infrequent but were largely low in severity. Refracture occurred only with a combined screw and suture anchor construct. Consistent return to sport was achieved across all fixation types, with no significant difference in complication rate between constructs, although the available study sample limited robust analysis. This study is also, of note, one of the first to report outcomes from cortical suspensory buttons (CSB)-a relatively novel intervention for AFIT. Findings from this retrospective case series of multiple surgical techniques serve to bolster the limited literature base regarding the operative treatment of AFITs in adolescents.

Arthroscopic Suture Anchor Fixation Results in Similar Clinical Outcomes, Less Range of Motion Limitation but Poorer Quality of Reduction compared to Open Screw Fixation for Acute Large Anterior Glenoid Rim Fractures

BackgroundThe purpose of the present study was to retrospectively compare the clinical and radiological outcomes of arthroscopic suture anchor fixation and open screw fixation for acute large anterior glenoid rim fractures. MethodsThis study enrolled patients with acute large anterior glenoid rim fractures treated with arthroscopic suture anchor fixation (group A) or open screw fixation (group O) from January 2013 to June 2020 with a minimum follow-up of＞2 years. The Subjective Shoulder Value (SSV), American Shoulder and Elbow Surgeons (ASES) score, Rowe score, Constant score, range of motion (ROM), recurrent instability rate, and complications were recorded as clinical results. The quality of the postoperative reduction, reconstructed glenoid sizes, rate of fracture healing, and progression of osteoarthritis (OA) were evaluated as radiological outcomes. ResultsThis retrospective study included 66 patients, including 37 in Group A and 29 in Group O with a mean follow-up of 46.9 (range, 24.3-94.2) months and a mean patient age of 46.8 (range, 21-69) years. No significant differences were found in the clinical outcomes between the two groups. A significant ROM limitation in all planes was found in both groups and group O showed more limitations in external rotation at the side (ERs) (18° vs. 10°, P = 0.002). The reduction quality was better in group O (P < 0.001). However, there was no significant difference between the two groups in terms of reconstructed glenoid size (101.6% ± 4.6% vs. 100.6% ± 7.1%, P = 0.460) and the rate of OA progression (26.9% vs. 20%, P = 0.525). ConclusionArthroscopic suture anchor fixation and open screw fixation achieved similar clinical outcomes, reconstructed glenoid sizes, and OA progression in patients with acute large anterior glenoid rim fractures. Arthroscopic suture fixation showed a poorer quality of reduction but less ERs limitations.

Refixation of aposterior medial root lesion in combination with centralization by ameniscotibial suture

Refixation of aposterior root lesion of the medial meniscus via atibial drill tunnel and prevention of extrusion using ameniscotibial suture (centralization). Posterior root lesion of the medial meniscus. Grade4 cartilage damage in the corresponding compartment, uncorrected varus or valgus deformities, symptomatic instabilities, extensive degenerative tears apart from the root region. Knee arthroscopy via the high anterolateral standard portal. Diagnostic arthroscopy to check indication. Locate the insertion zone on the tibial plateau and local debridement until the bone of the tibial plateau is visible. Insertion of atargeting device and drilling of atargeting wire into the center of the insertion zone in the area of the intercondylar eminence. Overdrill the target wire with a4.5 mm drill. Reinforcement of the medial meniscus posterior horn with braided suture material. The reinforcing thread is inserted into the bone tunnel via an eyelet wire with athread loop. Optional additional centralization with incision in the middle part of the meniscus. Reinforcement of the meniscus base with braided suture material using the "outside in" technique and fixation of the inner meniscus base at the edge of the tibial plateau using atransosseous extraction suture or asuture anchor. Six weeks nonweight-bearing (0kg), then gradually increased load. Range of motion: 4weeks E/F 0-0-60°, 2weeks 0-0-90°, optionally use of avalgus brace (varus of < 5°). In root lesions of the medial meniscus, transosseous refixation significantly improves knee function (Lysholm, Hospital for Special Surgery, International Knee Documentation Committee, visual analog scale for pain, Tegner, and Knee Injury and Osteoarthritis Outcome scores) and reduces osteoarthritis progression. However, atransosseous suture alone could not significantly reduce postoperative extrusion. However, previous studies have shown that additional centralization can significantly reduce extrusion.

Comparison of Knotless Versus Knot-Tying Suture Anchors for Arthroscopic Repair of Hip Labral Tears.

Both knotless and knot-tying anchors are commonly employed in the arthroscopic repair of hip labral tears. To compare the midterm clinical results of arthroscopic hip labral repair using knot-tying versus knotless suture anchors. Cohort study; Level of evidence, 3. Patients who underwent arthroscopic hip labral repair between January 2017 and January 2021 and who had at least 2 years of follow-up were included. The patients were divided into 2 groups based on the suture anchor type: a 2.9-mm knotless suture anchor (knotless group) or a 1.8-mm knot-tying suture anchor (knot-tying group). All patients underwent femoroplasty for cam lesions and acetabular rim trimming for pincer lesions. The modified Harris Hip Score (mHHS), Hip Outcome Score-Sport-Specific Subscale (HOS-SSS), Hip Outcome Score-Activities of Daily Living (HOS-ADL), 12-item International Hip Outcome Tool (iHOT-12), and visual analog scale (VAS) for pain were administered both preoperatively and postoperatively. The consistency of the outcome scores was assessed using the minimal clinically important difference and Patient Acceptable Symptom State. The statistical significance between groups was evaluated using the Mann-Whitney test and quantile-based analysis of variance. A total of 413 patients were included: 256 patients in the knotless group (median age, 35 years [interquartile range, 31-38 years]; median follow-up, 34 months) and 157 patients in the knot-tying group (median age, 34 years [interquartile range, 30-38 years]; median follow-up, 25 months). There were no significant differences in postoperative mHHS, HOS-ADL, or iHOT-12 scores between the 2 groups. However, there were significant differences, favoring the knotless group over the knot-tying group, in postoperative HOS-SSS (87 ± 2 vs 86 ± 1, respectively) and VAS pain (1 vs 2, respectively) scores (P < .0001 for both). Postoperative synovitis was found in significantly more patients in the knot-tying group than in the knotless group (17 vs 5, respectively; P = .01). In this study, patients who underwent arthroscopic hip labral repair with knotless suture anchors had slightly better postoperative HOS-SSS and VAS pain scores and a lower incidence of postoperative synovitis compared with patients who underwent repair with knot-tying suture anchors.

A novel design magnesium alloy suture anchor promotes fibrocartilaginous enthesis regeneration in rabbit rotator cuff repair

Regarding the current materials used for suture anchors for rotator cuff repair, there are still limitations in terms of degradability, mechanical properties, and bioactivities in clinical applications. Magnesium alloys have preliminarily been shown to promote tendon-bone healing with good prospects for application as anchor materials. However, the design of anchor structures for the degradation characteristics of magnesium alloy materials has not been considered, which is critical for the practical application of magnesium alloy anchors. The mechanism by which magnesium promotes tendon bone healing remains to be clarified. Here, we proposed a novel split hollowed magnesium alloy suture anchors for the repair of rabbit rotator cuff injury. We found that novel split hollowed magnesium alloy anchors structure effectively solved the problem of failure due to degradation of traditional eyelet structure, providing reliable suture fixation. The open architecture facilitates the metabolic resorption of the degradation products of and promotes the ingrowth of bone tissue. Histological staining showed that magnesium anchors have better ability to promote regeneration at the fibrocartilage interface compared to PLLA anchors. The higher expression of fibrocartilage markers (Aggrecan, COL2A1, and Sox9) at the tendon-bone interface in magnesium anchors, which promotes chondrocyte differentiation at the tendon-bone interface and matrix formation, which is more conducive to achieving regeneration and maturation of fibrocartilage enthesis. Hence, this study provides a basis for further research on the clinical application of degradable magnesium alloy suture anchors.

Blind-Tie Remplissage: Technique and Sequence

Patients with recurrent anterior shoulder instability and an associated Hill-Sachs lesion are commonly encountered by orthopaedic surgeons. Effective management of the Hill-Sachs lesion can be performed using an arthroscopic remplissage technique to fill the bony defect with the infraspinatus and posterior capsule. Various surgical techniques, anchor configurations, and tying mechanisms can be used to accomplish the remplissage procedure. The goal of this Technical Note is to describe our technique and sequence for accomplishing an arthroscopic “blind-tie” remplissage procedure. In this remplissage technique, the suture anchor sutures placed into the Hill-Sachs defect are tied in a blind fashion over the infraspinatus fascia without direct visualization from within the subacromial space.

Clinical Outcomes for Arthroscopic Anterior Talofibular Ligament Repair After Suture Anchor Insertion Through the Anterolateral Portal vs the Lateral Accessory Portal.

Two types of suture anchor insertion pathways (anterolateral portal vs lateral accessory portal) are used in arthroscopic anterior talofibular ligament (ATFL) repair. However, it is not clear which one is the better choice. This study aims to compare the clinical outcomes of these 2 suture anchor insertion pathways when performing arthroscopic ATFL lasso-loop repair for the treatment of chronic lateral ankle instability (CLAI). From 2019 to 2021, patients with CLAI who underwent arthroscopic ATFL lasso-loop repair were retrospectively reviewed and divided into the anterolateral portal (ALP) group and the lateral accessory portal (LAP) group. A 1:1 propensity score matching was used to control confounding factors based on age, sex, body mass index, follow-up duration, preoperative visual analog scale (VAS) score, and Tegner score (ALP group, n = 26; LAP group, n = 26). Karlsson score, VAS score, Tegner score, operation time, anterior drawer test results, patient symptoms, and magnetic resonance (MR) evaluation of ATFL quality were used to describe the outcomes. The patient characteristics and follow-up durations were similar between the 2 groups. After a mean follow-up duration of 28.8 ± 2.3 months, the ALP group had significantly better Karlsson score, VAS score, and Tegner score improvement than the LAP group, with fewer symptoms. Seven patients in the LAP group still had a feeling of ankle instability, and 3 of them exhibited ankle laxity. In this study, we found that inserting the suture anchor through the anterolateral portal was associated with better outcomes compared to that through the lateral accessory portal when performing arthroscopic ATFL lasso-loop repair for CLAI patients. The improvement was greater for pain relief and function and was associated with a lower frequency of subjective ankle instability.

3D-printed porous titanium suture anchor: a rabbit lateral femoral condyle model

BackgroundThe inclusion of a connecting path in a porous implant can promote nutrient diffusion to cells and enhance bone ingrowth. Consequently, this study aimed to evaluate the biomechanical, radiographic, and histopathological performance of a novel 3D-printed porous suture anchor in a rabbit femur model.MethodsThree test groups were formed based on the type of suture anchor (SA): Commercial SA (CSA, Group A, n = 20), custom solid SA (CSSA, Group B, n = 20), and custom porous SA (CPSA, Group C, n = 20). The SAs were implanted in the lateral femoral condyle of the right leg in each rabbit. The rabbits (New Zealand white rabbits, male, mean body weight of 2.8 ± 0.5 kg, age 8 months) underwent identical treatment and were randomized into experimental and control groups via computer-generated randomization. Five rabbits (10 femoral condyles) were euthanized at 0, 4, 8, and 12 weeks post-implantation for micro-CT, histological analysis, and biomechanical testing.ResultsAt 12 weeks, the CPSA showed a higher BV/TV (median 0.7301, IQR 0.7276–0.7315) than the CSSA and CSA. The histological analysis showed mineralized osteocytes near the SA. At 4 weeks, new bone was observed around the CPSA and had penetrated its porous structure. By 12 weeks, there was no significant difference in ultimate failure load between the CSA and CPSA.ConclusionsWe demonstrated that the innovative 3D-printed porous suture anchor exhibited comparable pullout strength to conventional threaded suture anchors at the 12-week postoperative time-point period. Furthermore, our porous anchor design enhanced new bone formation and facilitated bone growth into the implant structure, resulting in improved biomechanical stability.

Fixation failure and early loss of reduction with the use of suture anchors for surgical repair of acromioclavicular joint dislocation: a case series

IntroductionSuture anchors have been used in surgical repair of acromioclavicular joint (ACJ) dislocation. While some reports indicate favorable results, others emphasize less promising outcomes. This case series reports our experience with suture anchors for surgical treatment of ACJ dislocation. MethodsClinical and radiographic outcomes in three patients treated operatively for ACJ dislocations were reviewed. In all patients, two suture anchors were inserted in the coracoid (unicortical) and #5 non- absorbable suture from the suture anchor was shuttled through drill holes in the clavicle and tied over two button devices. The coracoclavicular (CC) ligaments were reconstructed using a figure of eight semitendinosus allograft around the coracoid and clavicle. Postoperatively, sling immobilization was used for 6 weeks, and physical therapy was initiated at 6 weeks with contact activity allowed at 6 months. ResultsThree male patients underwent treatment for Rockwood type 3 (chronic; n=1) and type 5 (n=2) ACJ dislocations. Loss of reduction was noted within 6 weeks postoperatively. Two patients exhibited failure due to complete suture anchor pullout and the third patient had partial pull out of one of the anchors. Additionally, the third patient also suffered a coracoid fracture adjacent to the anchor’s placement after sustaining direct trauma to his shoulder, one-year postoperatively. ConclusionIn our case series, we found a high rate of fixation failure and early loss of reduction with the use of suture anchors for the treatment of ACJ dislocation. These findings should be taken into consideration when selecting an appropriate implant for fixation of ACJ dislocation.

Comparative study of the early functional outcome of anatomic reconstruction of chronic lateral ankle instability with polyester tape reinforcement versus anchor repair

Purpose This study aims to compare the early functional outcome of anatomic reconstruction of chronic lateral ankle instability with polyester tape reinforcement versus suture anchor repair. Patients and Methods Sixty patients suffering from chronic lateral ankle instability were included. Thirty patients were treated by anatomic reconstruction of the injured ligaments and reinforcement with polyester tape and the other half was treated by suture anchors in our institution with a minimum period of 6 months follow-up. The postoperative results were assessed according to the American Orthopedic Foot and Ankle Surgery (AOFAS) scoring system for hind-foot. Results AOFAS score is improved postoperatively in both techniques without statistically significant difference (P=0.084). The results of the two techniques were comparable without statistically significant difference regarding pain, walking distance, hindfoot motion, foot alignment, activity limitation and support requirement (P=0.602, 0.067, 0.582, 0.448, 0.606, respectively). All the studied cases returned to their original activity level.

A Surgical Technique for Tibial Tubercle Avulsion Fractures Using Transpatellar Suture Tape Tension Band and De-tensioning Suture Anchors

This article aims to present a comprehensive technical note detailing our preferred treatment approach for tibial tuberosity avulsion fractures in the adult and elderly populations, particularly in scenarios characterized by low tissue quality and limited bone stock. Existing literature on this fracture type is scarce, with many described techniques relying on optimal bone quality for effective screw fixation of the tibial tuberosity. Various methods for tibial tuberosity avulsion fixation include K-wires, cannulated screws, staples, tension bands, suture anchors, and in select cases, direct transosseous sutures. Our technique focuses on robustly supporting the extensor mechanism through a synergistic combination of de-tensioning suture anchors, tension band suture taping, and suture augmentation of the patellar tendon. This approach addresses the challenges posed by compromised tissue quality and limited bone stock, offering a valuable contribution to the management of these fractures.

Paper 21: Anatomic Medial Ulnar Collateral Ligament Reconstruction with Internal Brace Augmentation in Throwing Athletes

Objectives: Injury to the Medial Ulnar Collateral Ligament (MUCL) is a common setback experienced by many throwing athletes often requiring reconstruction with 12-18 months of rehabilitation. Current reconstructive techniques fail to anatomically restore the MUCL which may contribute to the prolonged course of rehabilitation. In recent years, we described an anatomic MUCL reconstruction with internal brace augmentation which demonstrated improved biomechanical strength when compared to the docking technique in cadaveric specimens. The purpose of this study was to evaluate the postoperative course of both amateur and professional throwing athletes that underwent anatomic MUCL reconstruction with internal brace augmentation. We hypothesized that throwers would return to the same level of play and that return to play (RTP) would be a shorter duration compared to current reported outcomes. Methods: In this surgical technique, the native MUCL is formally repaired. The graft and a suture tape are folded over a suspensory loop and secured in a socket of the medial epicondyle of the humerus to maximize tendon to bone contact. On the ulnar side, the graft and internal brace are secured proximally by two suture anchors on either side of the sublime tubercle and further secured across the sublime tubercle ridge distally to re-create the anatomic triangular insertion of the native ligament. All surgeries were performed by a single surgeon. Patient reported outcomes in addition to date of RTP, level of play, and functional outcomes were retrospectively gathered. All patients initially followed an Accelerated Rehabilitation Protocol and were converted to a Standard Paced protocol if setbacks were encountered. Results: A total of 26 baseball players underwent primary (n=23) or revision (n=3) MUCL reconstruction with the Anatomic Technique. Of these, 15 were professional and 11 were amateur athletes. 92% of throwers returned to play at a mean of 9.9 months following reconstruction. 89% were able to advance through the accelerated postoperative protocol without issues and 85% returned to the same role and level of play. Post injury KJOC scores improved from 41 to 86.9 and SANE scores improved from 32.5 to 95.5. No significant difference was identified in pre-injury versus post-reconstruction throwing velocity, ball spin rate, or horizontal/vertical ball movement. Conclusions: Anatomic reconstruction of the MUCL with internal bracing is a viable option for MUCL injuries. Advantages include increased tendon-bone contact of the reconstruction, multiple fixation points, and anatomic restoration of the MUCL. This technique allowed an expedited return to sport for these baseball athletes.

Analysis of Calcaneal Avulsion Fractures Treated Surgically and Nonsurgically: A Retrospective Multicenter Study.

Calcaneal avulsion fractures (CAvFs) at the Achilles tendon insertion are among the more challenging fractures to treat. Although rare, they often require reoperation. The optimal treatment, including nonsurgical procedures and better implants for surgical procedures in the treatment of CAvFs, remains to be established. Therefore, our study aimed to (1) perform a descriptive evaluation of CAvFs, including cases managed nonsurgically, and (2) assess surgical procedures, including the incidence of complications and reoperation for surgically treated CAvFs. In this multicenter retrospective study, we collected data of patients with CAvFs treated at 9 hospitals from 2012 to 2022. We performed a descriptive study of CAvFs and compared postoperative complications and reoperation rates for multiple surgical techniques and implants. The size of the bone fragments was quantified. The data of 70 patients with CAvFs were analyzed; 20 patients were treated nonsurgically, and 50 were treated surgically. The mean age of patients was 68.5 years; 67% of the patients were female. Nineteen percent of the patients had diabetes, and 19% had osteoporosis. The incidence of postoperative complications was 30%, with infection in 14%, necrosis in 26%, and loss of reduction in 18%. The reoperation rate was 22%. Surgical techniques with use of cannulated cancellous screws were performed in 80% of the surgical cases. Cannulated cancellous screw (CCS) fixation alone resulted in a reoperation rate of 35%, whereas additional augmentation, including washers with CCS fixation, resulted in a reoperation rate of 10%. CCS fixation was successfully performed, although suture anchors were used in some cases with smaller fragments. CAvFs occurred more frequently in older women and had a high rate of postoperative complications. A combination of CCS with augmentation was more effective at reducing postoperative complications than CCS fixation alone, even when the bone fragment size was small. Therapeutic Level III.

Poster 154: Arthroscopic Rotator Cuff Repair With Side-to-Side Sutures for Full-Thickness Transtendinous Supraspinatus Tears Yields Excellent Outcomes and Low Retear Rates Similar to Traditional Tendon-to-Bone Fixation at Mean Follow Up of 4 Years

Objectives: Full-thickness transtendinous supraspinatus tears involve a large portion of the tendon that remains attached to the footprint that often leaves insufficient medial tissue for tension free footprint restoration with traditional suture anchor repair. The aim of this study was to compare outcomes and failure rates for arthroscopic side-to-side suture repair for transtendinous tears to traditional double-row repair for more common tendon avulsions. We hypothesized poorer objective and subjective outcomes as well as higher retear rates for side-to-side suture repair. Methods: This was a retrospective cohort study of 18 consecutive patients with full-thickness transtendinous supraspinatus tears repaired with arthroscopic side-to-side sutures (Group 1) compared to 36 matched controls with classic tendon avulsion from the footprint repaired with double-row knotless transosseous equivalent (TOE) repairs (Group 2). All procedures were performed by a single surgeon with a minimum of 2 years follow-up. Demographics and prospectively collected patient reported outcomes (PROs) were collected including postoperative active range of motion (AROM), American Shoulder and Elbow Surgeons (ASES) score, Visual analog scale (VAS) for pain, and Subjective Shoulder Value (SSV). Failure defined as a symptomatic re-tear diagnosed on magnetic resonance imaging (MRI) or need for revision surgery was also determined. Preoperative tear size and Goutallier stage were recorded from MRIs. Results: There were no significant differences between Group 1 and Group 2 regarding mean follow-up (49 months vs. 52.4 months, p = 0.640) and age (68.7 ± 6.8 vs. 67.1 ± 9.6, p = 0.550). With respect to clinical outcomes and PROs, there were no differences in postoperative VAS for pain score (1 ± 1.54 vs 1.5 ± 2.1, p = 0.537), SSV score (92.2 ± 9.1 vs 87.1 ± 10.9, p = 0.086), or ASES score (90.8 ± 9.9 vs 83.1 ± 23.9, p = 0.377). No differences were identified for postoperative AROM forward flexion (153 ± 14 vs 156 ± 16, p= 0.194), external rotation (53 ± 6 vs 51 ± 9, p= 0.498) and internal rotation score (6.4 ± 1.8 vs 7.2 ± 1.2, p=0.244). There was no statistically significant difference in failure rates between cohorts (11.1% vs. 2.7%, p = 0.255). Regarding preoperative tear characteristics, fatty infiltration of the supraspinatus (1.2 ± 1 vs 1.5 ± 0.7, p= 0.307) and anteroposterior tear size were similar (21.3 ± 9.3 vs 24 ± 8, p = 0.322), although lower grades of fatty infiltration in the infraspinatus was present in Group 1 (0.3 ± 0.6 vs 1.1 ± 0.7, p &lt; 0.001). Conclusions: Arthroscopic side-to-side suture repair for supraspinatus tears yields excellent outcomes with low failure rates comparable to tendon-to-bone double suture anchor repair for typical avulsion type tears. Retention of the large tendon stump on the greater tuberosity with side-to-side repair also allows restoration of anatomy without undue tension in this uncommon scenario.

Osseous Triceps Avulsion in a 12-Year-Old Girl: A Case Report.

A 12-year-old girl presented with significant right elbow pain following a fall during soccer which caused an osseous triceps avulsion injury and nondisplaced type II Salter-Harris radial neck fracture. The patient was treated with successful open repair utilizing suture anchor fixation, resulting in full return of function and return to previous activities. Timely and accurate diagnosis and treatment of displaced triceps sleeve avulsion injuries is critical and can result in excellent patient outcomes and return to previous functional level. This unique case contributes to the diagnosis and management of this rare condition in pediatric populations.

Revision Thumb Metacarpophalangeal Joint Ulnar Collateral Ligament Reconstruction With Autograft and Button Suspension.

Recurrent instability following thumb ulnar collateral ligament repair or reconstruction may result in pain and poor function. The use of certain suture anchors during the index procedure may predispose patients to the development of osteolysis and subsequent fixation failure. In this article, we describe an effective surgical technique for revision reconstruction of ulnar collateral ligament injuries using autograft and suture suspensionplasty. This technique restores joint stability and allows functional recovery with minimal postoperative complications.

Pectoralis major tendon rupture repairs using intramedullary suture anchors shows high patient-reported outcomes in military service members

BackgroundIn the general population pectoralis major tendon ruptures are uncommon; however, it is a common injury in the military population. The military service members have greater physical demands than the general population. The purpose of this study is to critically assess the post-operative outcomes of pectoralis major tendon ruptures in military service members following a repair using intramedullary suture anchors. PurposeTo report outcomes of pectoralis major repairs utilizing intramedullary suture anchors in military service members. MethodsA retrospective chart review was performed between 2014 to 2022, identifying patients who underwent a pectoralis major rupture repair performed by the senior surgeon using intramedullary suture anchors. Records were reviewed for age, gender, mechanism of injury, chronicity, VAS, and SANE scores. Patients who had less than 1 year of follow-up were excluded from the study. During the study period, 18 patients underwent surgical repair of their torn pectoralis major, and 15 patients were greater than 1-year post-operative. Twelve of these 15 patients (80%) were successfully contacted, and patient reported outcomes were collected. ResultsA total of 12 patients (12 male, 0 female) with a mean age of 34.5 years, were identified. Average time from injury to surgery was 471.4 days. The average duration of follow-up was 3.7 years. There was a decrease in the preoperative average single repetition maximum (1RM) barbell bench press of 277 lbs to a postoperative average 1RM bench press of 225 lbs (p-value=0.03). The average change in average 1RM barbell bench press is a 19.04% decrease postoperatively. Postoperative SANE score was 80.8 and an ASES of 86.9. Seven patients (58.3%) stated that they were afraid to bench press at their previous weight due to fear of reinjury. None of the patients were medically discharged from the military due to limitations from their repaired shoulder. Ten patients (83%) reported that they were extremely satisfied with their shoulder function post-operatively. ConclusionRepair of the pectoralis major tendon ruptures using intramedullary suture anchors has high rates of return to duty, patient satisfaction and patient reported outcomes. Greater than half of the patients reported that they were afraid to bench press at their preinjury weight due to concerns of reinjury; the decrease in post-operative strength may be a result of the patients’ fear of reinjury rather than physiologic limitations.
