Background: Arthroscopic capsulolabral reconstruction has proven to be effective in treating posterior shoulder instability. Few studies have examined the risk factors that may contribute to poor outcomes in the adolescent population. Purpose: To identify risk factors for surgical failure by comparing anatomic and subjective variations in children who underwent surgical intervention for posterior shoulder instability. Study Design: Case series; Level of evidence, 4. Methods: All patients undergoing arthroscopic shoulder surgery at one institution between 2011 and 2018 were reviewed. Patients >18 years old at presentation and those with Ehlers-Danlos syndrome were excluded. Posterior instability was defined as unidirectional subluxation on posterior drawer testing while under anesthesia. Two-year minimum follow-up was required, but those whose treatment failed earlier were included for calculation purposes. Demographics and intraoperative findings were recorded, as were Single Assessment Numeric Evaluation (SANE) scoring, Pediatric and Adolescent Shoulder Survey (PASS), and the short version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) results. Major complication was defined as revision arthroscopy or redislocation, and minor complications included self-reporting a poor outcome score (eg, SANE score <65). Results: A total of 48 children (23 girls and 25 boys) met criteria, with a mean age of 16.5 years (range, 12.4-17.9 years) and a mean follow-up of 3.75 years. Fifteen (31.3%) patients had a complication by our criteria, including 12.5% with surgical failures; regarding major complications, boys were treated successfully 96% of the time and girls 78% of the time ( P = .049). Of the anatomic and subjective variables tested, only younger age ( P≤ .001) and presentation type ( P < .05) were correlated with complications. SANE scores differed significantly ( P < .002) by presentation type, with mean scores of 52 (trauma), 94 (recurrent instability), and 81 (pain). QuickDASH scores demonstrated patients with a history of trauma (mean, 37), instability (mean, 9), and pain (mean, 11). Conclusion: Adolescents treated surgically for posterior shoulder instability are at risk of treatment failure (when including outcome scores), and it appears that patients of female sex, younger age, and traumatic presentation are at the highest risk to require revision surgery or experience continued limitations secondary to their shoulder.

Background: Multidirectional shoulder instability (MDI) refractory to rehabilitation can be treated with arthroscopic capsulolabral reconstruction with suture anchors. To the best of our knowledge, no studies have reported on outcomes or examined the risk factors that contribute to poor outcomes in adolescent athletes. Purpose: To identify risk factors for surgical failure by comparing anatomic, clinical, and demographic variables in adolescents who underwent intervention for MDI. Study Design: Case series; Level of evidence, 4. Methods: All patients 20 years or younger who underwent arthroscopic shoulder surgery at a single institution between January 2009 and April 2017 were evaluated. MDI was defined by positive drive-through sign on arthroscopy plus positive sulcus sign and/or multidirectional laxity on anterior and posterior drawer tests while under anesthesia. A 2-year minimum follow-up was required, but those whose treatment failed earlier were also included. Demographic characteristics and intraoperative findings were recorded, as were scores on the Single Assessment Numeric Evaluation (SANE), Pediatric and Adolescent Shoulder Survey (PASS), and short version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH). Results: Overall, 42 adolescents (50 shoulders; 31 female, 19 male) were identified as having undergone surgical treatment for MDI with minimum 2-year follow-up or failure. The mean follow-up period was 6.3 years (range, 2.8-10.2 years). Surgical failure, defined as recurrence of subluxation and instability, was noted in 13 (26.0%) shoulders; all underwent reoperation at a mean of 1.9 years (range, 0.8-3.2 years). None of the anatomic, clinical, or demographic variables tested, or the presence of generalized ligamentous laxity, was associated with subjective outcomes or reoperation. Number of anchors used was not different between shoulders that failed and those that did not fail. Patients reported a mean SANE score of 83.3, PASS score of 85.0, and QuickDASH score of 6.8. Return to prior level of sport occurred in 56% of patients. Conclusion: Adolescent MDI refractory to nonsurgical management appeared to have long-term outcomes after surgical intervention that were comparable with outcomes of adolescent patients with unidirectional instability. In patients who experienced failure of capsulorrhaphy, results showed that failure most likely occurred within 3 years of the index surgical treatment.

Background: Posterior shoulder instability is associated with nonspecific symptoms, including pain, subluxation, and functional impairment, which complicate its diagnosis and management. Owing to the rarity of the condition, there are no present decision tools for its diagnosis and treatment. Purpose: To investigate demographic, lesional, and surgical factors that influence functional outcomes in patients treated for posterior shoulder instability. Study Design: Case-control study; Level of evidence, 3. Methods: We analyzed the clinical and radiographic records of 150 patients treated surgically for isolated posterior shoulder instability at 10 centers between 2000 and 2015, of which 144 were eligible for inclusion: 114 men (79%) and 30 women (21%) (mean ± SD age, 28.7 ± 9.6 years). The mean time between onset of symptoms and surgery was 66 ± 75 months. Shoulder instability was of traumatic origin in 115 patients (80%). The primary treatment was bone-block procedures for 65 patients (45%), posterior Bankart repair for 67 (47%), and capsular plication for 12 (8%). Patients were assessed with the Constant and Walch-Duplay scores at a mean follow-up of 51 ± 32 months (range, 12-159 months). Uni- and multivariable regression analyses were performed to determine associations between clinical scores and sex, age, traumatic origin, type of lesion, type of procedure, and follow-up. Results: At final follow-up, subluxations or dislocations recurred in 24 patients (17%). The overall Constant score was 86.2 ± 14.5, with a pain component of 12.6 ± 3.5. The Walch-Duplay score was 79.8 ± 24.2. Multivariable regressions revealed that the presence of a glenoid cartilage lesion was the only factor associated with worse Constant score (beta = –10; P = .013) and Walch-Duplay score (beta = –16.7; P = .024) across all subcomponents. Conclusion: The only factor that jeopardized functional outcomes of posterior instability surgery was the presence of glenoid cartilage lesions. Knowing that shoulders with glenoid cartilage lesions are at greater risk of residual pain or instability could help manage patient expectation and justify faster intervention before lesions deteriorate.

Background: Arthroscopic treatment of posterior shoulder instability has become more popular and effective in recent years, but few data are available concerning the rate of return to sport. Purpose: To present our experiences with arthroscopic posterior labral reconstruction in athletes and review our results, with a particular focus on the rate of return to sport. Study Design: Case series; Level of evidence, 4. Methods: Included in the study were 40 arthroscopic stabilizations performed because of posterior shoulder instability in 37 athletes at a single institution. During follow-up, the athletes’ rate of return to sport was calculated. Shoulder function was evaluated based on a pre- versus postoperative comparison of the Rowe instability score and the American Shoulder and Elbow Surgeons score. Additionally, the return-to-sport rate was compared among different subgroups: traumatic versus atraumatic origin of injury, competitive versus recreational athletes, high-risk versus low-risk sport, and posterior-only versus anterior and posterior stabilization. Data were statistically analyzed using paired-samples t test and nonparametric Fisher exact test. Results: The average follow-up period was 54.4 months (range, 24-112 months). Three shoulders (7.5%) continued to have posterior subluxations postoperatively. There were 34 excellent, 3 good, and 3 fair results based on the Rowe score (average postoperative score, 92.9), and patients achieved an average postoperative American Shoulder and Elbow Surgeons score of 92.7. The pre- to postoperative improvement was statistically significant in both scoring systems ( P < .001). Of the 37 patients, 36 (98.2%) were able to return to sport activity: 27 of them (72.9%) to their original sport and 19 (51.4%) at their preinjury level. A significantly higher rate of return to the same sport occurred in athletes who had traumatic injury compared with a subgroup of athletes without a traumatic event ( P < .02). Conclusion: More than half of the athletes were able to return to their preinjury level of sport after arthroscopic posterior labral reconstruction. In addition, low recurrence rates and good functional outcomes were seen in >90% of the patients, and 98% returned to sport activity. The athletes had a significantly higher rate of return to sport if their posterior shoulder instability had a clear traumatic origin.

Objectives: Among patients treated non-operatively for 1 year following a diagnosis of posterior shoulder instability (PSI), little is known about the the incidence of surgery between 1-13 years after injury. The purpose of this study is to define the frequency and evaluate the factors predictive for late surgical intervention of symptomatic PSI. Methods: This study included a population-based cohort of 115 patients (14 females, 101 males) diagnosed with PSI between January 1994 and July 2012 with a minimum 5-years follow-up (mean:13.9 years; range: 5-23 years). Landmark survival analysis was performed to evaluate incidence of surgery after 1 year. Survival was estimated using Kaplan Meier method and predictors of late surgical intervention were analyzed using Cox proportional hazards regression. Results: A total of 61/115 (53%) patients were treated non-operatively for 1 year following diagnosis of PSI. Of these, 24/61 (39%) converted to surgery for symptomatic PSI. The overall survival free of surgery at 1 and 5 years was 53.0% (95% CI 434.7-63.0) and 37.1% (95% CI 29.1-47.1), respectively. BMI >35 (p=0.04, HR 3.3) was predictive for late conversion to surgery. Age, gender, occupation, or history of glenohumeral dislocation were not significant. Assessing surgery as a time dependent covariate, a patient undergoing surgery was at an increased risk for radiographic progression of osteoarthritis (p=0.02, HR=4.0, 95% CI 1.2-13.2). Conclusion: Conservative management was performed for at least one year in over half of patients diagnosed with PSI. However, long-term follow-up demonstrates that nearly 40% of these patients eventually require surgery. Increased BMI was predictive for late failure of while age, gender, history of dislocation and occupation did not show an effect. Patients who underwent surgery were at an increased risk of radiographic progression of arthritis.

Purpose To evaluate the long-term outcome of a modified inferior capsular shift procedure in patients with atraumatic anterior-inferior shoulder instability by analyzing a consecutive series of patients who had undergone a modified inferior capsular shift for this specific type of shoulder instability. Study Design Case series; Level of evidence, 4. Methods Between 1992 and 1997, 38 shoulders of 35 patients with atraumatic anterior-inferior shoulder instability that were unresponsive to nonoperative management were operated on using a modified capsular shift procedure with longitudinal incision of the capsule medially and a bony fixation of the inferior flap to the glenoid and labrum in the 1 o'clock to 3 o'clock position. The patient study group consisted of 9 men and 26 women with a mean age of 25.4 years (range, 15-55 years) at the time of surgery. The mean follow-up was 7.4 years (range, 4.0-11.4 years); 1 patient was lost to follow-up directly after surgery. The study group was evaluated according to the Rowe score. Results After 7.4 years, 2 patients experienced a single redislocation or resubluxation, 1 patient had recurrent dislocations, and 1 patient had a positive apprehension sign, which is an overall redislocation rate of 10.5%. The average Rowe score increased to 90.6 (SD = 19.7) points from 36.2 (SD = 13.5) points before surgery. Seventy-two percent of the patients participating in sports returned to their preoperative level of competition. Conclusions Results in this series demonstrate the efficacy and durability of a modified capsular shift procedure for the treatment of atraumatic anterior-inferior shoulder instability.

Background:Most patellar dislocations occur in a lateral direction because of a summed lateral force vector and predisposing anatomic risk factors. Medial patellar instability is rare and is a well-recognized iatrogenic complication of an overly aggressive lateral retinacular release. Noniatrogenic medial patellar dislocations are rare. The management of these injuries is not well described.Purpose:To describe the experience of the International Patellofemoral Study Group with patients with noniatrogenic medial patellar dislocation.Study Design:Case series; Level of evidence, 4.Methods:Members of the International Patellofemoral Study Group (N = 64) were surveyed between October 2018 and April 2019. This group was chosen because of its wide referral base and interest in patellar instability. Specialists who had encountered a patient with medial patellar instability were sent a questionnaire inquiring about details of the case, including patient demographics, medical history, level of athletic competition, injury characteristics, and treatment. Cases were confirmed by physical examination records and, in some cases, with findings on advanced radiographic imaging.Results:The survey response rate was 73% (47/64). Three of the 47 specialists (6.4%) reported they had seen a case of noniatrogenic medial patellar dislocation, for a total of 6 cases. Four cases were described as recurrent medial dislocations in the setting of hypermobile Ehlers-Danlos syndrome; 2 were treated nonoperatively, 1 underwent lateral patellofemoral ligament reconstruction, and 1 underwent derotational osteotomies. Two medial-sided patellar dislocations in collegiate athletes were sports-related injuries that required surgical debridement but no ligamentous reconstruction. None of the patients had persistent or recurrent instability at the time of their most recent follow-up.Conclusion:Noniatrogenic medial patellar dislocations are extremely rare. This case review suggests that the treatment of first-time medial patellar instability in patients without known risk factors should follow the same principles as the treatment of lateral instability with no known risk factors, which is nonoperative management. For patients with documented risk factors and recurrence, surgery to address the risk factors may be appropriate.

Background: Risk factors associated with short-term functional outcomes in patients with operative ankle fractures have been established. However, no previous studies have reported the association between these risk factors and functional outcomes outside of the first postoperative year. We identified predictors of functional and pain outcomes in patients with operative ankle fractures using the Patient Reported Outcomes Measurement System (PROMIS) physical function (PF) and pain interference (PI) measures. Methods: We retrospectively reviewed a multicenter cohort of patients ≥18 years old who underwent operative management of closed ankle fractures from 2001 to 2013 with a minimum of a 2-year follow-up. Patients with pilon variants, Maisonneuve fractures, Charcot arthropathy, prior ankle surgery, and chronic ankle fractures were excluded. Patients meeting inclusion criteria were contacted and evaluated using the PROMIS PF and PI computerized adaptive tests. Patient demographic and injury characteristics were obtained through a retrospective chart review. Univariate and multivariate regression models were developed to determine independent predictors of physical function and pain at follow-up. Included in this study were 142 patients (64 women, 78 men) with a mean age of 52.7 years (SD = 14.7) averaging 6.3 years of follow-up (range 2-14). Results: Patients had a mean PF of 51.9 (SD = 10.0) and a mean PI of 47.8 (SD = 8.45). Multivariate analysis demonstrated that independent predictors of decreased PF included higher age (B = 0.16, P = .03), higher American Society of Anesthesiologists (ASA) class (B = 10.3, P < .01), and higher body mass index (BMI; B = 0.44, P < .01). Predictors of increased PI included higher ASA class (B = 11.5, P < .01) and lower BMI (B = 0.41, P < .01). Conclusion: At follow-up, increased ASA class, increased BMI, and higher age at time of surgery were independently predictive of decreased physical function. Factors that were associated with increased pain at follow-up include lower BMI and higher ASA class. ASA class had the strongest effect on both physical function and pain. Level of Evidence: Level IV, case series.

Background: Anterior and posterior shoulder instabilities are entirely different entities. The presenting complaints and symptoms vastly differ between patients with these 2 conditions, and a clear understanding of these differences can help guide effective treatment. Purpose: To compare a matched cohort of patients with anterior and posterior instability to clearly outline the differences in the initial presenting history and overall outcomes after arthroscopic stabilization. Study Design: Cohort study; Level of evidence, 2. Methods: Consecutive patients with either anterior or posterior glenohumeral instability were prospectively enrolled; patients were excluded if they had more than 10% anterior or posterior glenoid bone loss, multidirectional instability, neurologic injury, or prior surgery. Patients were assigned to anterior or posterior shoulder instability groups based on the history and clinical examination documenting the primary direction of instability, with imaging findings to confirm a labral tear associated with the specific direction of instability. Preoperative demographic data, injury history, and overall clinical outcome scores (American Shoulder and Elbow Surgeons [ASES], Single Assessment Numeric Evaluation [SANE], and Western Ontario Shoulder Index [WOSI]) were assessed and compared statistically between the 2 cohorts. Patients were indicated for surgery if they elected to proceed with surgical management or did not respond to a course of nonoperative management. Results: The study included 103 patients who underwent anterior stabilization (mean age, 23.5 years; range, 18-36 years) and 97 patients who underwent posterior stabilization (mean age, 24.5 years; range, 18-36 years). The mean follow-up was 39.7 months (range, 24-65 months), and there were no age or sex differences between the groups. No patients were lost to follow-up. The primary mechanism of injury in the anterior cohort was a formal dislocation event (82.5% [85/103], of which 46% [39/85] required reduction by a medical provider), followed by shoulder subluxation (12%, 12/103), and “other” (6%, 6/103; no forceful injury). No primary identifiable mechanism of injury was found in the posterior cohort for 78% (75/97) of patients; lifting and pressing (11%, 11/97) and contact injuries (10% [all football blocking], 10/97) were the common mechanisms that initiated symptoms. Only 10 patients (10.3%) in the posterior cohort sustained a dislocation. The most common complaints for patients with anterior instability were joint instability (80%) and pain with activities (32%). In the posterior cohort, the most common complaint was pain (90.7%); only 13.4% in this cohort reported instability as the primary complaint. Clinical outcomes after arthroscopic stabilization were significantly improved in both groups, but the anterior cohort had significantly better outcomes in all scores measured: ASES (preoperative: anterior 58.0, posterior 60.0; postoperative: anterior 94.2 vs posterior 87.7, P < .005), SANE (preoperative: anterior 50.0, posterior 60.0; postoperative: anterior 92.9 vs posterior 84.9, P < .005), and WOSI (preoperative: anterior 55.95, posterior 60.95; postoperative: anterior 92% of normal vs posterior 84%, P < .005). Conclusion: This study outlines clear distinctions between anterior and posterior shoulder instability in terms of presentation and clinical findings. Patients with anterior instability present primarily with an identifiable mechanism of injury and complaints of instability, whereas most patients with classic posterior instability have no identifiable mechanism of injury and their primary symptom is pain. Anterior instability outcomes in this matched cohort were superior in all domains versus posterior instability after arthroscopic stabilization, which further highlights the differences between anterior and posterior instability.

Background: Hammertoe correction is perhaps the most common elective surgery performed in the foot, yet rates of symptomatic recurrence and revision surgery can be high. In this study, we aimed to identify patient and provider risk factors associated with failure after hammertoe surgery. Methods: Consecutive patients with a minimum of 6 months’ follow-up undergoing hammertoe surgery within a single, urban foot and ankle practice between January 1, 2011, and December 31, 2013, served as the basis of this retrospective cohort study. Cox regression analysis was used to identify important predictor variables obtained through chart and radiographic review. One hundred fifty-two patients (311 toes) with a mean age of 60.8 ± 11.2 years and mean follow-up of 29.5 ± 21.2 months were included. Results: Statistically significant predictors of failure were having a larger preoperative transverse plane deviation of the digit (hazard ratio [HR], 1.03 for each degree; P < .001; 95% CI, 1.02, 1.04), operating on the second toe (vs third or fourth) (HR, 2.23; P = .003; 95% CI, 1.31, 3.81), use of a phalangeal osteotomy to reduce the proximal interphalangeal (PIP) joint (HR, 2.77; P = .005; 95% CI, 1.36, 5.64), and using less common/conventional operative techniques to reduce the PIP joint (HR, 2.62; P = .03; 95% CI, 1.09, 6.26). Concomitant performance of first ray surgery reduced hammertoe recurrence by 50% (HR, 0.51; P = .01; 95% CI, 0.30, 0.87). Conclusion: We identified risk factors that may provide guidance for surgeons during preoperative hammertoe surgery consultations. This information may better equip patients with appropriate postoperative expectations when contemplating surgery. Level of Evidence: Level III, retrospective case series.
