Clinical outcomes following open anterior shoulder stabilization for glenohumeral instability in the young collision athlete.

BACKGROUND: Anterior glenohumeral instability occurs most commonly in those aged 15-29, with 72% of individuals younger than 22 years suffering recurrent episodes; collision athletes are at particular risk. In the setting of subcritical glenoid bone loss, arthroscopic Bankart repair is widely used despite concerns of recurrent dislocations when compared with open techniques. Furthermore, indications for bone-block procedures are evolving with the Latarjet procedure being favored amongst recent authors as a primary stabilization method in elite and contact athletes. OBJECTIVE: To determine the efficacy of open modified Bankart stabilization in treating anterior glenohumeral instability in young collision athletes. METHODS: This was a retrospective review of outcomes of consecutive patients aged 15-20 years who underwent unilateral or bilateral open stabilization for recurrent anterior glenohumeral instability over a 7-year period (2007-2015). The cohort was selected as recent literature suggests that this is the group with the highest redislocation rate and poorest outcomes. Outcome assessments included redislocation rate, return to sport, pain score, patient-related satisfaction scores, and the Western Ontario Shoulder Instability Index. RESULTS: A total of 60 patients (55 male: 5 female) of mean age 18 years (range: 15-20 years) were available for follow-up at 7 years. All but 3 were competitive athletes with 18 competing regionally and 9 internationally; rugby union and rugby league represent the most common sports. Fifty-five of 60 (92%) have returned to their desired level of sport with 62% of athletes returning to their previous level of competition sport and 1 retuning at a higher level. The mean postoperative pain score was 2.5/10. The mean time to return to play was 14 months (range: 5-48 months). Eight of 60 shoulders reported redislocation (13%), 7 of these being traumatic dislocations after return to high-impact sporting activities. At 7 years of follow-up, 4 of 60 shoulders (7%) had undergone revision surgery. CONCLUSION: Young collision athletes represent a challenging cohort of instability patients. This study of open modified Bankart in young collision sport athletes revealed excellent outcomes with 92% return to sport and a low revision rate. The results from this cohort rival those of arthroscopic repair. The open procedure described here in this 7-year series represents a robust, reliable technique that could be considered as an alternative to arthroscopic Bankart due to concern for recurrence, while avoiding potential morbidity and complication of bone-block procedures. There is still a role for the open modified Bankart procedure in treating traumatic anterior instability.

Outcomes of a 2-Portal Endoscopic Technique for Osseous Lesions Resulting in Posterior Ankle Impingement Syndrome.

Posterior ankle impingement syndrome is common in sporting populations and encompasses a range of disorders that cause posterior ankle pain during maximal forced plantarflexion. The aim of this study was to evaluate the short- and medium- to long-term outcomes of 2-portal endoscopic surgery for osseous lesions causing posterior ankle impingement syndrome. This was a retrospective case series analysis of all patients who underwent 2-portal endoscopic surgery at a single institution between 2005 and 2016. Visual analogue scales and selected components of the Short Form of the Revised Foot Function Index were used to assess ankle function, with the median follow-up time being 4.8 years. Of the 52 patients, 49 (94%) were able to return to their previous sport/physical activity, with the mean time taken being 5.8 months. At the completion of follow-up, the mean pain score during exercise had improved from 7.5 to 0.9 points. The mean work and sporting function scores also improved, from 5.9 to 9.6 points and 2.9 to 8.8 points, respectively. The mean score of the Short Form of the Revised Foot Function Index also improved by 77.7 points, from 84.4 to 6.7 at the completion of follow-up. There were no postoperative infections or any other major complications. This study provides strong supporting evidence for the use of hindfoot endoscopy in the treatment of posterior ankle impingement syndrome in athletes.

Arthroscopic treatment of anterior ankle impingement: a prospective study of 46 patients with 5-year follow-up.

BACKGROUND: Midterm outcomes after arthroscopic debridement in patients with anterior ankle impingement without osteoarthritis are currently unclear. PURPOSE: To assess the functional and radiological outcomes after arthroscopic treatment of anterior ankle impingement with a minimum 5-year follow-up in patients without osteoarthritis. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: From September 1999 to March 2006, a consecutive series of eligible patients without ankle osteoarthritis and with anterior ankle impingement, who had persistent ankle pain and activity restrictions despite at least 6 months of nonoperative management, underwent standardized arthroscopic debridement and followed uniform postoperative management. Patients were assessed preoperatively and at 6 weeks, 6 months, and 12 months and then at 1-year intervals after surgery until a minimum of 5 years' follow-up had been achieved, with weightbearing ankle dorsiflexion, Foot Functional Index (FFI), and plain radiography including Scranton and McDermott classification (SMC) grade and tibial osteophyte size. RESULTS: A total of 46 patients (42 male, 4 female) were prospectively assessed, with a mean age at surgery of 29 years (range, 16-44 years) and a mean follow-up duration of 5.1 years (range, 5.0-7.5 years). Preoperative ankle radiographs demonstrated a median SMC grade of 2 and a mean tibial osteophyte size of 5.1 mm. At a minimum of 5 years postoperatively, patients demonstrated limited improvement in ankle dorsiflexion (mean, 24.7° [preoperatively] vs 27.0° [final follow-up]; P = .049); however, they demonstrated substantial improvement in the FFI (mean, 20.5 [preoperatively] vs 2.7 [final follow-up]; P < .001). Postoperatively, 84% of patients showed a recurrence of radiological osteophytes, with plain radiographs at final follow-up demonstrating no significant difference in the SMC grade (P = .107) or tibial osteophyte size (P = .212) compared with preoperative imaging. There was no significant effect of patient age, sex, body mass index, or SMC grade at the time of surgery on any of the postoperative outcome measures. CONCLUSION: In this prospective outcome study of 46 patients without osteoarthritis managed arthroscopically for anterior ankle impingement, the functional outcome scores had significantly improved at 5 years postoperatively despite a recurrence of radiographic osteophytes.

Ponseti method compared with surgical treatment of clubfoot: a prospective comparison.

BACKGROUND: Current trends in the treatment of idiopathic clubfoot have shifted from extensive surgical release to more conservative techniques. The purpose of the present study was to prospectively compare the results of the Ponseti method with those of surgical releases for the correction of clubfoot deformity. METHODS: We prospectively compared patients who had idiopathic clubfoot deformities that were treated at a single institution either with the Ponseti method or with below-the-knee casting followed by surgical release. The clinical records of the patients with a minimum duration of follow-up of two years were reviewed. All scheduled and completed operative interventions and associated complications were recorded. RESULTS: Fifty-five patients with eighty-six clubfeet were treated; forty feet were included in the group that was treated with the Ponseti method, and forty-six feet were included in the group that was treated with below-the-knee casts followed by surgery (with three of these feet requiring casting only). There was no difference between the groups in terms of sex, ethnicity, age at the time of first casting, pretreatment Pirani score (average, 5.2 in both groups), or family history. The average number of casts was six in the Ponseti group and thirteen in the surgical group. Of the feet that were treated with below-the-knee casts, forty-three underwent surgery, with forty-two undergoing major surgery (posterior release [eleven] or posteromedial release [thirty-one]). In the Ponseti group, fourteen feet required fifteen operative interventions for recurrences, with only one foot requiring revision surgery. Four of these fifteen were major (necessitating posterior [one] or posteromedial release [three]) while eleven were minor. Thirteen feet in the surgical group required fourteen surgical revisions. Two postoperative complications were seen in each group. CONCLUSIONS: While both cohorts had a relatively high recurrence rate, the Ponseti cohort was managed with significantly less operative intervention and required less revision surgery. The Ponseti method has now been adopted as the primary treatment for clubfoot at our institution.

Resource utilization in clubfoot management.

UNLABELLED: Both private and socialized healthcare systems require treatments to be not only effective, but also cost-efficient. Although the Ponseti method of clubfoot treatment is effective, its cost-effectiveness has not been demonstrated. We compared the difference in resource use between two prospective cohorts treated for clubfoot by either the Ponseti method or below-knee casting followed by primary surgical release in the socialized healthcare system of New Zealand. Using these cohorts and US billing data, costs of treating these cohorts in the US healthcare system were also calculated. Treatment of initial deformity, recurrences, and complications in both cohorts were included in the final assessment. Twenty-six patients (40 feet) were enrolled in the Ponseti cohort and 29 (46 feet) in the primary surgical cohort. For most patients, the Ponseti method was more cost-effective than the primary surgical treatment in both healthcare systems. The cost of treating both cohorts was lower in the socialized system than in the US healthcare system. LEVEL OF EVIDENCE: Level II, prognostic study.

Large osteochondral fractures of the lateral femoral condyle in the adolescent: outcome of bioabsorbable pin fixation.

BACKGROUND: Large osteochondral fractures of the lateral femoral condyle of the knee in adolescent patients can be diagnostically and therapeutically challenging. Historically, management has involved removal of the fragment, leaving a large area of bone devoid of articular cartilage on the weight-bearing surface of the lateral femoral condyle. This study assessed open reduction and internal fixation of the osteochondral fragments with use of multiple polyglycolic acid rods. METHODS: Eight patients, between twelve and fifteen years old, with a large (>4 cm(2)) osteochondral fracture of the lateral femoral condyle were treated with open reduction and internal fixation with use of multiple polyglycolic acid rods. Each patient was evaluated at more than five years (a mean of nine years) after the index procedure with a clinical assessment, during which the knee was scored according to the International Knee Documentation Committee and Cincinnati knee rating systems, plain radiographs were made, and magnetic resonance imaging scans were acquired. RESULTS: The majority of patients scored well on both knee rating systems, with no poor results. Five of the eight patients had normal findings on knee radiographs, and three had radiographs that showed minor changes. Magnetic resonance imaging scans of all patients demonstrated intact articular cartilage in the lateral compartment with no area of full-thickness articular cartilage loss. No evidence of articular cartilage thinning was seen in two knees; a small area of <2 cm(2) of cartilage thinning, in four; a moderate area of 2.7 cm(2) of cartilage thinning, in one; and a large area of 11.2 cm(2) of abnormal cartilage signal, in one knee. CONCLUSIONS: Osteochondral fracture of the lateral femoral condyle is an injury to which adolescents with ligamentous laxity of the knee are prone. Our results show that internal fixation of these osteochondral fragments with bioabsorbable implants is possible and is a worthwhile option.
