Persistent lateral elbow pain from overlooked posterolateral impingement of the elbow: a literature review and guidance for treatment.

Posterolateral impingement is sometimes diagnosed as a cause of refractory elbow pain, often after other treatments have been tried for common conditions such as lateral epicondylitis (tennis elbow) or subtly different conditions common in throwing athletes, such as valgus extension overload syndrome. Arthroscopic surgical treatment is effective when targeting abnormal anatomy such as plical folds. Partial excision of the olecranon must be undertaken with caution because it can lead to instability. This systematic review of the current literature uses a narrative synthesis to identify anatomical morphological variations of the olecranon, humeral and capitellar geometry, and overloading of the lateral part of the elbow as causative factors for this condition and discusses how arthroscopic techniques can resolve symptoms. Further understanding of the static and dynamic anatomy of the lateral part of the elbow will help to develop future treatment and preventive strategies.

Arthroscopic Chondral Ankle Treatment: A Multicenter Outcome Study

Introduction/Purpose: Chondral injuries of the ankle are common, often requiring surgical intervention. The purpose of this multicenter study of ankle osteochondral injuries is to report minimum one year outcomes for patients undergoing arthroscopic surgical treatment. Methods: Thirty-nine patients undergoing arthroscopic surgery to treat chondral ankle injuries between December 2017 and January 2022 were enrolled in the present multicenter study. Intraoperative information including diagnoses and procedures performed were recorded. All patients completed the Visual Analog Scale for Pain (VAS), the Veteran RAND 12-Item Health Survey (VR-12) Physical and Mental component scales, and Foot and Ankle Ability Measure Sports subscale (FAAM-S). These measures were collected at the pre-operative visit within two weeks before surgery and at a minimum of one year post- operatively. Patient demographics and perioperative complications were also recorded. Paired T-test was used to determine statistical significance. Results: Of the thirty-nine patients with a minimum of 1 year follow-up, the average age was 46 years old and 51% were male. Average patient BMI was 29. Laterality was right in 54% of the patients, and 8% of surgeries were revisions. Relative to baseline, there was a significant decrease in VAS at minimum 1-year post-operatively (4.9 to 1.7, p< 0.001). Additionally, the VR-12 Physical was significantly higher at minimum 1-year post-operatively (35.4 to 46.8, p< 0.001). The VR-12 Mental was also significantly higher at minimum 1-year post-operatively (47.6 to 54.6, p=0.005). Finally, there was a significant increase in FAAM Sports (11.3 to 34.0, p< 0.001). There were no recorded complications. Conclusion: For patients undergoing arthroscopic surgery to treat chondral ankle injuries, our study found significant improvements in self-reported pain, overall physical health, overall mental health, and sport activities at minimum one-year follow- ups with no complications.

A Technique for Arthroscopic Fixation of Tibial Eminence Avulsion Fractures: A Physeal-Sparing Construct With All-Suture Anchor Bridge Fixation

Arthroscopic or open surgical treatment is indicated for displaced tibial spine fractures to obtain anatomic reduction and restore the functionality of the anterior cruciate ligament. Numerous open and arthroscopic techniques for the treatment of tibial spine fractures have been described. The purpose of this technical note is to describe a minimally invasive arthroscopic physeal- and ligament-sparing surgical technique using knotless all-suture anchors to provide stable bridge fixation over displaced tibial spine fractures.

Translated article] Efficacy of transplantation of lipoaspired mesenchymal stem cells in the treatment of chronic rotator cuff tears. Experimental model in rats

Background and aimRotator cuff tears emerge in approximately 30% of the population over 60 years of age. Arthroscopic surgical treatment of these lesions is the treatment of choice, however, despite the improved repair techniques, the rate of re-tears ranges between 11 and 94%. Therefore, researchers seek to improve the biological healing process through the use of different alternatives such as mesenchymal stem cells (MSCs). Our objective is to evaluate the efficacy of a cellular therapy drug made from allogeneic stem cells derived from adipose tissue in a rat model of chronic rotator cuff injury. Material and methodsThe supraspinatus lesion was created in 48 rats for subsequent suturing at 4 weeks. MSCs in suspension were added to 24 animals after suturing, and HypoThermosol-FRS® (HTS) to 24 animals as a control group. Histology (Åström and Rausing scale) and the maximum load, displacement and elastic constant of the supraspinatus tendon were analysed in both groups 4 months after the repair. ResultsNo statistically significant differences were found in the histological score comparing the tendons treated with MSCs with respect to the tendons treated with HTS (P=0.811) nor in the results of maximum load (P=0.770), displacement (P=0.852) or elastic constant (P=0.669) of the tendon in both groups. ConclusionsThe addition of adipose-derived cells in suspension to the repair of a chronic cuff injury does not improve the histology or biomechanics of the sutured tendon.

Assessment of Coracoclavicular Ligament Healing on MRI After Arthroscopic TightRope Fixation for Acute Acromioclavicular Joint Dislocation.

Arthroscopic-assisted fixation of acute high-grade acromioclavicular (AC) joint dislocation has gained popularity in the last decade. Coracoclavicular (CC) fixation using the TightRope device is a less invasive technique. To investigate CC ligament healing and functional outcomes after arthroscopic fixation using the TightRope device for acute AC joint disruption. Case series; Level of evidence, 4. The study retrospectively analyzed the data of patients admitted for arthroscopic surgical treatment of acute AC joint injury using a single TightRope device. The data collection commenced in October 2021. The Constant-Murley (CM) score and University of California, Los Angeles (UCLA) shoulder score were used for functional evaluation. The CC distance (CCD) was measured on plain radiographs, whereas healing of the CC ligament was evaluated on magnetic resonance imaging (MRI). Statistical analyses were conducted with the Mann-Whitney U test, independent t test, or paired t test, as appropriate. The analysis included 33 patients with a mean age of 37.7 years (range, 24-49 years) and a minimum follow-up of 24 months. Significant preoperative to postoperative increases were noted in both the CM and UCLA scores (from 34.1 ± 7.6 to 93.3 ± 3.6 and from 8.7 ± 2.1 to 32.9 ± 1.7, respectively; P < .0001 for both). The CCD decreased from 21.8 ± 3.02 mm preoperatively to 10.6 ± 1.2 mm postoperatively (P < .0001). All patients displayed CC ligament healing on MRI. Two patients with superficial infection and 1 case of partial reduction loss were confirmed at the end of this study. The arthroscopic TightRope technique was found to be a reliable and less invasive method of fixation for acute AC joint disruptions. The CC ligament healed adequately based on MRI evaluation, and the patients regained their preinjury activities, with favorable functional outcomes and minor comorbidities.

Hip Arthroscopy with Acetabular Osteoplasty and Labral Repair

Hip arthroscopy with femoral neck or acetabular osteoplasty with or without labral repair can be used for treatment of femoroacetabular impingement. Patients may present with insidious onset of hip pain and mechanical symptoms and pain worse with activity and sitting. On physical exam hip flexion and internal rotation may be reduced and anterior impingement testing will produce groin pain in the majority of patients with femoroacetabular impingement. Imaging may demonstrate lesions responsible for Cam-type or Pincer-type impingement and MRI may demonstrate labral tear or cartilaginous lesions. Arthroscopic surgical treatment is indicated for patients who have failed conservative treatment.

Arthroscopic Resection Arthroplasty for Scapholunate Advanced Collapse Wrist.

Purpose Scapholunate advanced collapse (SLAC) wrist results from an untreated scapholunate dissociation and is the most common type of degenerative arthritis of the wrist. The most common surgical treatments for SLAC wrist are proximal row carpectomy and four-corner fusion with scaphoid excision. Arthroscopic surgical treatment for SLAC wrist has been reported; however, only limited data on functional outcomes are available. The purpose of this study is to report our 5-year follow-up clinical outcomes for arthroscopic treatment for SLAC wrist. Methods Thirty-one consecutive cases of arthroscopic resection arthroplasty for SLAC wrist were reviewed. Preoperative and postoperative Disabilities of the Arm, Shoulder, and Hand (DASH) scores, range of motion, grip strength, and pain (on 0-10 scale) as well as postoperative satisfaction (0 = not satisfied, 5 = completely satisfied) were recorded. Grip and range of motion were measured by an occupational therapist. Results The preoperative pain score was 7 and 0.18 postoperatively. The mean satisfaction at final follow-up was 4.8. Preoperative and final follow-up scores of the mean DASH was 48 and 3, respectively. The total arc of motion was 114 degrees preoperatively and 126.5 degrees postoperatively. Mean grip strength before surgery was 41 and 49 kg at final follow-up. Conclusion Arthroscopic resection arthroplasty for SLAC wrist results in significant improvement in patient function as measured by DASH and pain scores. Type of Study/Level of Evidence Therapeutic IV.

ConclusionsThe addition of adipose-derived cells in suspension to the repair of a chronic cuff injury does not improve the histology or biomechanics of the sutured tendon.

Interscalene block applied by an experienced anesthesiologist has a good anesthetic effect, a long duration of action, and less postoperative pain after arthroscopic shoulder procedures independent of surgery type and operation duration.

This study aims to evaluate the severity of postoperative pain and the time to the onset of pain after arthroscopic surgical treatment of rotator cuff tear or instability under interscalene block. Between October 2015 and June 2016, a total of 172 patients (82 males, 90 females; mean age: 47.9±16.9 years; range, 15 to 83 years) who underwent shoulder arthroscopy under interscalene block by a single surgeon were retrospectively analyzed. The relationship between the postoperative 24-h Visual Analog Scale (VAS), the time to the onset of pain with the type of surgical procedure (rotator cuff repair, n=101 or instability surgery, n=71), and the duration of surgery (<30 min n=92; ≥30 min n=80) was examined. No significant relationship was found between the type of surgical procedure, VAS scores, and the onset of pain after the block (p=0.577 and p=0.780, respectively). No significant relationship was found between the operation duration, and VAS, and the onset of pain after the block (p=0.570 and p=0.408, respectively). The mean duration until the start of postoperative pain was 734±313 (range, 60 to 1,440) min. There was no statistically significant difference in the need for rescue analgesics at the postoperative 24th h and the duration of surgery between the two groups (p=0.393 and p=0.675, respectively). Our study results show no significant difference in the time for the onset of postoperative pain and the VAS scores according to the characteristics of the surgical procedure, operation duration, or age and sex of the patient. Shoulder arthroscopy performed by experienced surgeons under interscalene block eliminates the need for analgesics within the first 12 h postoperatively.

Instability of the distal tibiofibular syndesmosis.

The distal tibiofibular syndesmosis (DTFS) is more frequently injured than previously thought. Early diagnosis and appropriate treatment is essential to avoid long term complications like chronic instability, early osteoarthritis and residual pain. Management of these injuries require a complete understanding of the anatomy of DTFS, and the role played by the ligaments stabilizing the DTFS and ankle. High index of suspicion, appreciating the areas of focal tenderness and utilizing the provocative maneuvers help in early diagnosis. In pure ligamentous injuries radiographs with stress of weight bearing help to detect subtle instability. If these images are inconclusive, then further imaging with MRI, CT scan, stress examination under anesthesia, and arthroscopic examination facilitate diagnosis. An injury to syndesmosis frequently accompanies rotational fractures and all ankle fractures need to be stressed intra-operatively under fluoroscopy after fixation of the osseous components to detect syndesmotic instability. Non-operative treatment is appropriate for stable injuries. Unstable injuries should be treated operatively. Anatomic reduction of the syndesmosis is critical, and currently both trans-syndesmotic screws and suture button fixation are commonly used for syndesmotic stabilization. Chronic syndesmotic instability (CSI) requires debridement of syndesmosis, restoration of ankle mortise with or without syndesmotic stabilization. Arthrodesis of ankle is used a last resort in the presence of significant ankle arthritis. This article reviews anatomy and biomechanics of the syndesmosis, the mechanism of pure ligamentous injury and injury associated with ankle fractures, clinical, radiological and arthroscopic diagnosis and surgical treatment.

Артроскопическое оперативное лечение у возрастных пациентов с остеоартрозом коленного сустава

Chronic arthropathies are currently one of the most key problems among diseases of the musculoskeletal system. The problem of treating osteoarthritis, aimed not only at reducing symptoms, but also at lowering the rate of progression, especially in people of older age groups, has important socio-economic significance. The purpose of the study: to evaluate the results of arthroscopic surgical treatment of age-related patients with osteoarthritis of the knee joint.Methods. The article presents the results of arthroscopic treatment of age-related patients with osteoarthros is of the knee joint. The study included 65 patients with degenerative-dystrophic changes in intra-articular structures (meniscal injury, chondromatosis, synovitis, contracture due to mechanical obstruction, exostoses, osteophytes, inflammatory diseases), with the exception of patients with traumatic injuries of the capsular-ligamentous apparatus (damage to the cruciate, medial and lateral lateral ligaments, capsule) of the knee joint. The age of patients ranged from 61 to 85 years, 61-75 years - 50 (76.1%), older than 75 years - 15 (23.9%) patients. The mean age of the patients was 64.3±1.8 years. Among them, men - 21 (32.3%), women - 44 (67.70%). The ratio of males and females was 1:3. We performed arthroscopy of the knee joint using the standard anterior approach described by H. Hempfling.Results. When assessing the dynamics of pain intensity on a visual analogue scale, it was possible to achieve a decrease in pain up to 5 points. Positive results of treatment were obtained in the form of cessation of night pain after 3-7 days after surgery and the disappearance of pain after 3-4 weeks. In the postoperative period after arthroscopic debridement, it was possible to achieve positive treatment results according to the Lequesne scale up to 2-3 points.Сonclusions. The results showed that arthroscopic surgical treatment in patients of older age groups allows eliminating mechanical obstacles to joint excursions and restoring the normal range of motion of the knee joint, restoring cartilage nutrition in patients with knee contracture, and removing the inflammatory process.Key words: knee joint, osteoarthrosis, gonarthrosis, arthroscopy of the knee joint.

Low-dose prophylaxis protocol for heterotopic ossification after hip preservation surgery in a sport participants cohort.

Heterotopic ossification (HO) is a well-known complication of arthroscopic and open surgical treatment of femoroacetabular impingement (FAI). Incidence of heterotopic ossification has been reported in the literature between 0% and 44% after hip arthroscopy and between 18.2% and 25% after anterior mini-open surgery. Currently, pharmacological prophylaxis with NSAIDs and selective COX-2 inhibitors are commonly used and their effectiveness is well documented in literature. We hypothesized that the low-dose prophylaxis protocol with selective cox-2 inhibitors decreases the risk of heterotopic ossification in open or arthroscopic hip preservation surgery in athletes. This study is an analysis of prospectively gathered data on 98 sport participant patients who underwent arthroscopic or anterior mini-open treatment for FAI between April 2008 and April 2018. All the patients received postoperative oral prophylaxis with 60mg etoricoxib once daily for two weeks. Post-operative X-rays were performed at 1, 3, and 12 months after surgery and reviewed by two orthopedic surgeons blinded to the type and side of surgery. HO were graded according to the Brooker classification. Descriptive statistics was used to analyze demographic data. Bivariate analysis was performed to analyze the association of HO with each of the following variables: type of surgery, physical activity, time of evolution of symptoms, age at surgery, and sex. Finally, a regression model analysis was performed to determine the presence of confounding effects between variables. The study cohort was composed of 54 patients in the arthroscopic treatment group and 44 patients in the anterior mini-open group. HO was identified in 6 (13.6%) patients in the mini-open group. No HO was identified in the arthroscopic group. In the bivariate analysis, "type of surgery" was the only variable that showed a statistically significant association with HO (p=0.007). Results of this study suggest that anterior mini-open treatment was characterized by a higher risk of HO development compared to hip arthroscopy for femoroacetabular impingement treatment regardless of pharmacological prophylaxis. The treatment regimen of 60 mg etoricoxib daily for two weeks was an effective prophylaxis for HO formation in sport participant patients compared with data available in the literature.

Arthroscopic treatment of diffuse pigmented villonodular synovitis of the elbow

IntroductionPigmented villonodular synovitis (PVNS) is a rare pathology of the elbow, but presents a risk of progression with cartilage destruction. Surgical treatment consists in synovectomy, as complete as possible. Arthroscopy is an excellent tool for the exploration and treatment of intra-articular lesions in the elbow, but the results in PVNS of the elbow have never been evaluated. The aim of this study was to assess the recurrence rate of PVNS of the elbow after arthroscopic synovectomy, and secondarily to assess pain, joint range of motion, functional scores and complication rate. Material and methodsWe performed a retrospective study of a continuous series of 8 patients operated on between February 2012 and February 2019, with a mean age of 43.7 years. The operated side was the dominant side in 75% of cases. Surgery consisted in the most complete synovectomy possible, performed arthroscopically. Recurrence, clinical evaluation, with pain at rest and on mpvement on visual analogue scale (VAS) and joint range of motion, functional MEPS and DASH scores, and any complications were collected. ResultsAt a mean 66.4 months’ follow-up, 2 patients required revision surgery for recurrence. At the last follow-up, VAS for pain at rest was 0.9 and 1.9 for pain on movement. MEPS score was 85.6 and DASH score 82.2. No neurological, vascular or infectious complications of arthroscopic synovectomy were found in our series. DiscussionArthroscopic synovectomy in the treatment of PVNS of the elbow was a reliable and safe therapeutic alternative, with a low complications rate and 2 cases of recurrence (25%) in our study. This was the first study to report the results of arthroscopic surgical treatment of elbow PVNS. Level of evidenceIV Retrospective study without control group.

Surgical treatment for rotator cuff tears: the way it ought to be

Background: Among many diseases associated with shoulder pain, rotator cuff tear with and without arthritis accounts for most of the surgical cases. We aimed to briefly review the arthroscopic surgical treatment and prognosis for rotator cuff tears.Current Concepts: Traditionally, rotator cuff tears have been treated using open surgery; however, with the development of arthroscopic surgery, the arthroscopic suture method has been preferred. Nevertheless, in cases of partial rotator cuff tears exceeding more than 50% of the total thickness and not responding to conservative treatment for longer than 6 months, surgical treatment is considered. In cases of complete rotator cuff tears, in addition to the preoperative factors, the amount of tension applied to the suture site at the time of surgery and force coupling recovery of the rotator cuff are important factors for successful arthroscopic suturing. Furthermore, various methods such as patch augmentation using human dermis or bone marrow stimulation have been utilized to increase the success rate of sutures in extensive rotator cuff tears. Even after cuff repair, appropriate rehabilitation and pain control are important for optimal outcomes. Superior capsule reconstruction has gained substantial attention since it was first reported; however, further studies on its feasibility, indications, and outcomes are warranted.Discussion and Conclusion: We reviewed the arthroscopic surgical treatment and prognosis for rotator cuff tears. The study reveals that the prognosis can be improved if the treatment is tailored to the individual patient's environment or situation.

Anatomic safe zones for arthroscopic snapping scapula surgery: quantitative anatomy of the superomedial scapula and associated neurovascular structures and the effects of arm positioning on safety.

Neurovascular anatomy has not been previously quantified for the arthroscopic snapping scapula approach with the patient in the most frequent patient position ("chicken-wing" position). The purposes of this study were (1) to determine anatomic relationships of the superomedial scapula and neurovascular structures at risk during arthroscopic surgical treatment of snapping scapula syndrome (SSS), (2) to compare these measurements between the arm in the neutral position and the arm in the chicken-wing position, and (3) to establish safe zones for arthroscopic treatment of SSS. Eight fresh-frozen cadaveric hemi-torsos (mean age, 55.8 years; range, 52-66 years) were dissected to ascertain relevant anatomic structure locations including the (1) spinal accessory nerve, (2) dorsal scapular nerve, and (3) suprascapular nerve. A coordinate measuring device was used to collect data on the relationships of anatomic landmarks and at-risk structures during the surgical approach. The dorsal scapular nerve was a mean of 24.4 mm medial to the superomedial scapula in the neutral position and 33.1 mm medial in the chicken-wing position (P<.001); the dorsal scapular nerve was 21.7 mm medial to the medial border of the scapular spine in the neutral position and 35.5 mm medial in the chicken-wing position (P<.001). The mean distance from the superomedial angle to the spinal accessory nerve intersection at the superior scapular border was 16.5 mm in the neutral position and 15.0 mm in the chicken-wing position (P=.031). The average distance from the superomedial angle to the closest point of the spinal accessory nerve was 11.6 mm and 10.4 mm in the neutral position and chicken-wing position, respectively (P=.039). Neurologic structures around the scapula vary significantly between the neutral arm position and the chicken-wing position commonly used in the arthroscopic treatment of SSS. The chicken-wing position improves safe distances for the dorsal scapular nerve during medial-portal placement and should be considered as a primary position for arthroscopic management of SSS.

Expression and distribution pattern of aggrecanases and miR-140s in the thickened synovia of shoulder joints in rotator cuff tears: A retrospective observational study.

The rotator cuff (RC) is frequently torn at the enthesis composed of fibrocartilage. We aimed to histopathologically evaluate lining layers and assess the distribution of a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS)4, ADAMTS5, and microRNA (miR)-140s in the synovia of patients with RC tears. We recruited 51 patients who underwent arthroscopic surgical treatment for full-thickness rotator cuff tears, including 26 patients with < 3 cm tear size (group N) and 25 patients with ≥ 3 cm tear size (group W). Biopsied synovia were analyzed using histological and immunohistological techniques for the presence ADAMTS4 and ADAMTS5. The layers of the synovial lining were morphologically classified into 3 grades according to the synovitis score and staining levels of ADAMTSs. The glenohumeral synovia from 8 patients with recurrent shoulder dislocation (group C) were used as controls. Furthermore, in situ hybridization was performed to evaluate the presence of miR-140s in patients with massive tears and recurrent shoulder dislocation. The staining levels were evaluated and analyzed based on comparison between patient groups and correlation between ADAMTS5 and miR-140s. Histological analysis revealed significant differences between groups W and C. ADAMTS5 and ADAMTS4 were strongly expressed in the synovial lining of patients in group W, and this expression was significantly higher than that in groups C and N. In addition, expression of ADAMTS5 was inversely correlated with that of miR-140-3p. This study showed that synovia from group W had a significantly higher rate of severely thickened areas with strong expression of both aggrecanases. Furthermore, the area with weak expression of miR-140-3p showed strong ADAMTS5 expression.

Влияние повреждений TFCC, сочетанных с переломом ДМЭЛК, на отдаленные результаты функции кисти: сравнительное исследование

Introduction Fractures of the distal metaepipheseal fractures of the radius (DMER) have a leading place in the overall structure of upper limb injuries. DMER fractures are frequently associated with soft- tissue injuries of the wrist joint, and namely, the triangular fibrocartilage complex (TFCC). The additional use of arthroscopy of the wrist joint in the treatment of patients with a DMER fractiures reduces the duration of recovery of patients and improves the result of their treatment. The aim of the study was to determine the effect of arthroscopic surgical treatment of TFCC injuries during bone osteosynthesis for DMER fractures on the functions of the upper extremities (extension/flexion of the hand, hand grip strength, pronation/supination of the forearm, DASH index). Materials and methods The study included 68 patients with DMER fractures, who were divided into 2 groups, depending on the treatment of the fracture. After reduction and osteosynthesis, all patients underwent arthroscopy of the wrist joint. If TFCC injury was detected, either a debridement or a TFCC suture was performed. Results TFCC injury was detected in 61.7 % (n = 42). Debridement was performed in 42.9 % (n = 18); suture using the inside-out technique was performed in 47.6 % (n = 20); one patient underwent reinsertion. After 6 months, the function of flexion and extension of the hand was significantly worse in patients with combined TFCC and DMER injuries, but after 12 months, the indicators were similar. The strength of the hand grip and the rotational function of the forearm did not differ between the subgroups. The subjective assessment of DASH after 6 months was worse in the group with TFCC injury, but after 12 months the results were similar. Conclusion Surgical treatment of TFCС injury in intraarticular fractures of the distal radius contributes to the restoration of the upper limb function to a premorbid level 12 months after surgical treatment.

Morphology of Glenoid Cartilage Defects in Anteroinferior Glenohumeral Instability.

Background:Glenoid cartilage defects may contribute to anterior shoulder instability recurrence and progression to osteoarthritis, but their morphology remains unknown.Purpose/Hypothesis:The purpose was to determine the shape, size, and location of glenoid cartilage defects and the prevalence and risk factors for cartilage defects in the setting of anterior glenohumeral instability. It was hypothesized that glenoid cartilage defects would be common, would be associated with recurrence of dislocation, and would share similar morphology with glenoid osseous defects.Study Design:Cross-sectional study; Level of evidence, 3.Methods:In this retrospective study, all patients who underwent arthroscopic surgical treatment for anterior glenohumeral instability between January 2012 and May 2019 were included; excluded were patients with documented posterior or multidirectional instability or previous glenohumeral surgery. For each patient, the operative report, arthroscopic images, and preoperative magnetic resonance imaging (MRI) scans were reviewed to determine the prevalence of cartilage injury. For those patients with an Outerbridge grade 3 or 4 defect, the cartilage surfaces on the MRI scans were segmented to make 3-dimensional (3-D) segmentations. From these 3-D segmentations, we measured length, width, and surface area of the glenoid and defect, and the orientation of the defect relative to the superior and inferior poles of the glenoid. A multivariable analysis was conducted to determine correlates with cartilage damage.Results:In 322 patients treated operatively for anterior glenohumeral instability, 38% had a concomitant cartilage defect. The mean cartilage defect was located directly anteriorly at the 3:07 clockface position (range, 2:10-4:05) and encompassed 6.5% ± 3.5% of the glenoid surface area. However, defects ranged up to >56% of glenoid length and up to 27% of glenoid width, and the largest defect encompassed 19.5% of the glenoid cartilage surface area. Patients with a cartilage defect were more likely to be male (P = .031) and to have undergone a concomitant posterior labral repair (P = .018).Conclusion:Cartilage defects were common in patients with operatively treated anterior glenohumeral instability, occurring in 38% of patients. These defects were located directly anteriorly at 3:07, similar to osseous glenoid defects. Future prospective studies with cartilage-specific MRI sequences should be conducted.

Most Elite Athletes Who Underwent Hip Arthroscopy for Femoroacetabular Impingement Syndrome Did Not Return to the Same Level of Sport, but the Majority Were Satisfied With the Outcome of Surgery

PurposeTo evaluate the 2-year outcomes after arthroscopic surgical treatment for femoroacetabular impingement syndrome (FAIS) using validated patient-reported outcome measurements in young elite athletes and to report the rate of return to sport.MethodsYoung elite athletes undergoing arthroscopic surgery for FAIS with 2 years of follow-up were included. A young elite athlete was defined as an athlete aged 18 to 22 years at the time of surgery with a Hip Sports Activity Scale (HSAS) level greater than 6 before the onset of symptoms. The following patient-reported outcome measurements were collected prospectively: Copenhagen Hip and Groin Outcome Score, 12-item International Hip Outcome Tool, HSAS, visual analog scale (VAS), European Quality of Life (EQ) 5 Dimensions questionnaire, and EQ VAS. Furthermore, the patients answered a question related to satisfaction with surgery at follow-up.ResultsA total of 84 athletes (67 male and 17 female athletes), with a mean age of 19.8 ± 1.5 years, completed the 2-year follow-up. Bilateral hip arthroscopy was performed in 57 athletes, generating a total of 141 included hips. The improvements in the Copenhagen Hip and Groin Outcome Score subscales, 12-item International Hip Outcome Tool, EQ 5 Dimensions questionnaire, EQ VAS, and VAS for overall hip function were statistically significant (P < .001). At the 2-year follow-up, 42% of the athletes reported an HSAS level of either 7 or 8 whereas 28% reported an HSAS level of 5 or 6. In total, 79% of the athletes were satisfied with the surgical procedure.ConclusionsThere are significant improvements in outcome measurements at the 2-year follow-up in elite young athletes undergoing arthroscopic hip surgery for FAIS. Although many of the athletes remained in high-level sports 2 years after surgery, only 30% of the athletes returned to sport at the same level.Level of EvidenceLevel IV, therapeutic case series.

FUNCTIONAL EVALUATION OF THE RESULTS OF REPAIR OF PARTIAL AND COMPLETE ROTATOR CUFF TEARS.

ABSTRACTObjective: To perform a comparative analysis of the results of arthroscopic surgical treatment of partial and complete rotator cuff (RC) injuries. Methods: Eighty-four shoulders with partial or complete RC tear that underwent arthroscopic repair were retrospectively evaluated using UCLA and Constant scores, assessment of strength, and range of motion. Fifty-seven shoulders with complete injuries and 27 with partial injuries were identified. Results: Age (p = 0.007) was higher in those with complete lesions (mean 61.4 ± 7.9 years), compared to those with partial lesions (mean 56.5 ± 7.1 years). The complete injuries group showed a higher elevation difference in relation to the contralateral shoulder compared to the partial injuries group (partial injuries: −1.1% vs complete injuries: −16.5%), statistically significant difference (p = 0.0004). In addition, complete lesions presented 96.5% of excellent and good results and a median of 35 in the UCLA score and partial lesions presented 84.6% of good/ excellent results and a median of 34. The Constant score showed 91.2% of satisfactory results in complete lesions and 77% in partial ones. Conclusion: Arthroscopic repair shows satisfactory functional results for both partial and complete rotator cuff injuries, with similar outcomes between groups.
