Arthroscopic Stabilization After a First-Time Dislocation: Collision Versus Contact Athletes

Outcomes of Shoulder Instability Surgery in Competitive Wrestlers: Outcomes, Reoperations, and Return to Play at 5 Years' Mean Follow-up

BACKGROUND

Wrestling is a physically demanding sport with young athletes prone to traumatic shoulder instability and a paucity of data evaluating the results of shoulder instability surgery (SIS).

PURPOSE

To assess reoperation rates, patient-reported outcomes, and return to wrestling (RTW) after SIS in a cohort of competitive wrestlers.

STUDY DESIGN

Case series; Level of evidence, 3.

METHODS

All competitive wrestlers with a history of shoulder instability and subsequent surgery at a single institution between 1996 and 2020 were identified. All directions of shoulder instability (anterior shoulder instability [ASI], posterior shoulder instability [PSI], and traumatic multidirectional shoulder instability [TMDI]) were analyzed. Exclusions included revision SIS and <2 years of follow-up. Athletes were contacted for determination of complications, RTW, and Western Ontario Shoulder Instability Index scores.

RESULTS

Ultimately, 104 wrestlers were included with a mean age at initial instability of 16.9 years (range, 12.0-22.7 years), mean age at surgery of 18.9 years (range, 14.0-29.0 years), and a mean follow-up of 5.2 years (range, 2.0-22.0 years). A total of 58 (55.8%) wrestlers were evaluated after a single shoulder instability event, while 46 (44.2%) sustained multiple events before evaluation. ASI was the most common direction (n = 79; 76.0%), followed by PSI (n = 14; 13.5%) and TMDI (n = 11; 10.6%). Surgical treatment was most commonly an arthroscopic soft tissue stabilization (n = 88; 84.6%), with open soft tissue repair (n = 13; 12.5%) and open bony augmentation (n = 3; 2.9%) performed less frequently. RTW occurred in 57.3% of wrestlers at a mean of 9.8 months. Recurrent instability was the most common complication, occurring in 18 (17.3%) wrestlers. Revision SIS was performed in 15 (14.4%) wrestlers. Across the entire cohort, survivorship rates free from recurrent instability and revision surgery were 90.4% and 92.5% at 2 years, 71.9% and 70.7% at 5 years, and 71.9% and 66.5% at 10 years, respectively. Preoperative recurrent instability was an independent risk factor for postoperative recurrent instability (hazard ratio, 3.8; 95% CI, 1.33-11.03; P = .012).

CONCLUSION

Competitive wrestlers with multiple dislocations before initial clinical evaluation were 3.8 times more likely to experience postoperative recurrent instability. Patients should be counseled that despite SIS, only 57.3% returned to wrestling after surgery.

Return to sports after arthroscopic Bankart repair in teenage athletes: a retrospective cohort study

BACKGROUND

Anterior shoulder instability is frequent among young athletes. Surgical treatment for this injury aims to facilitate an early return to sports (RTS). However, the rate of recurrent instability after surgery is reportedly high among young patients, and it is unclear whether surgery ensures satisfactory RTS. The purpose of this study was to verify the clinical outcomes and RTS after arthroscopic Bankart repair in competitive teenage athletes without critical bone loss in the glenoid.

METHODS

We retrospectively reviewed competitive teenage athletes who underwent arthroscopic Bankart repair. Patients with large bony defects in the glenoid, larger than 20% of the healthy side, were excluded. Clinical outcomes, recurrent instability, the final level of RTS, and the time needed for RTS were analyzed.

RESULTS

In total, 50 patients with a mean follow-up period of 44.5 ± 19.6 (range, 24-85 months) months were included. The mean age at surgery was 16.8 ± 1.7 (range, 13-19 years) years. Two patients (4.0%) experienced recurrent instability. All patients returned to sports, 96% of patients participated competitively, and 76% achieved a complete return to the pre-injury level without any complaints. The time for RTS was 6.6 ± 2.7 months (range, 3-18 months), to competitions was 9.3 ± 4.0 (range, 6-24 months) months, and to complete return was 10.6 ± 4.3 (range, 8-24 months) months. The complete return rates varied by sports type, with 82% in contact athletes, 59% in dominant-hand overhead athletes, and 100% in other athletes (P = 0.026). Other preoperative factors or concomitant lesion such as bony Bankart, superior labrum tear, or humeral avulsion of glenohumeral ligament lesion did not affect the complete RTS.

CONCLUSION

Arthroscopic Bankart repair is an effective surgical procedure for anterior shoulder instability, even among competitive teenage athletes. Sports type was the only factor associated with complete RTS after surgery.

Return to sports, functional outcomes, and recurrences after arthroscopic Bankart repair in soccer players

BACKGROUND

There is a shortage of relevant reports about the results obtained after shoulder stabilization in soccer players. Therefore, this retrospective study aims to report return to sports, functional outcomes, and recurrences after arthroscopic Bankart repair in soccer players.

METHODS

A total of 156 soccer players were treated for anterior shoulder instability at a single institution between 2008 and 2017. The Rowe score and Athletic Shoulder Outcome Scoring System were used to assess functional outcomes. Return to sport and recurrence rates were also evaluated.

RESULTS

The Rowe and Athletic Shoulder Outcome Scoring System scores showed statistical improvement after surgery (P < .001). Overall, 148 soccer players (94.8%) returned to sports, and 122 (78.2%) returned to the same level. The mean time to return to sport was 4.8 months. The recurrence rate was 5.2%.

DISCUSSION

Soccer players who underwent an arthroscopic isolated Bankart repair for anterior glenohumeral instability have shown remarkable outcomes, with most of the patients returning to sports, and at the same level they had before surgery with a low rate of recurrence.

Bipolar Bone Defects in Shoulders With Primary Instability: Dislocation Versus Subluxation

Background:

In shoulders with traumatic anterior instability, a bipolar bone defect has been recognized as an important indicator of the prognosis.

Purpose:

To investigate bipolar bone defects at primary instability and compare the difference between dislocation and subluxation.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

There were 156 shoulders (156 patients) including 91 shoulders with dislocation and 65 shoulders with subluxation. Glenoid defects and Hill-Sachs lesions were classified into 5 size categories on 3-dimensional computed tomography (CT) scans and were allocated scores ranging from 0 (no defect) to 4 points (very large defect). To assess the combined size of the glenoid defect and Hill-Sachs lesion, the scores for both lesions were summed (range, 0-8 points). Patients in the dislocation and subluxation groups were compared regarding the prevalence of a glenoid defect, a bone fragment of bony Bankart lesion, a Hill-Sachs lesion, a bipolar bone defect, and an off-track Hill-Sachs lesion. Then, the combined size of the bipolar bone defects was compared between the dislocation and subluxation groups and among patients stratified by age at the time of CT scanning (<20, 20-29, and ≥30 years).

Results:

Hill-Sachs lesions were observed more frequently in the dislocation group (75.8%) compared with the subluxation group (27.7%; P < .001), whereas the prevalence of glenoid defects was not significantly different between groups (36.3% vs 29.2%, respectively; P = .393). The combined defect size was significantly larger in the dislocation versus subluxation group (mean ± SD combined defect score, 2.1 ± 1.6 vs 0.8 ± 0.9 points, respectively; P < .001) due to a larger Hill-Sachs lesion at dislocation than subluxation (glenoid defect score, 0.5 ± 0.9 vs 0.3 ± 0.6 points [P = .112]; Hill-Sachs lesion score, 1.6 ± 1.2 vs 0.4 ± 0.7 points [P < .001]). Combined defect size was larger in older patients than younger patients in the setting of dislocation (combined defect score, <20 years, 1.6 ± 1.2 points; 20-29 years, 1.9 ± 1.5 points; ≥30 years, 3.4 ± 1.6 points; P < .001) but was not different in the setting of subluxation (0.8 ± 1.0, 0.7 ± 0.9, and 0.8 ± 0.8 points, respectively; P = .885). An off-track Hill-Sachs lesion was observed in 2 older patients with dislocation but was not observed in shoulders with subluxation.

Conclusion:

The bipolar bone defect was significantly more frequent, and the combined size was greater in shoulders with primary dislocation and in older patients (≥30 years).

Timelines for returning to physical activity following pediatric spinal surgery: recommendations from the literature and preliminary data

Objective

Participation in physical activity and sports is known to have positive implications for physical health, and for social and emotional wellbeing of children. Following corrective spinal surgery for scoliosis, the timeline for the return to activities and sports varies from surgeon to surgeon and from location to location, and return to activities can be limited due to pain, fear, and decreased flexibility. It is critical that patients know best-practice guidelines, and it is equally critical that medical professionals know whether their patients are following those guidelines. This paper includes a summary of recommendations published in the literature, and a pilot study to address a gap in the literature on determining how long, post-surgery, adolescents with idiopathic scoliosis waited before returning to various self-care and physical activities, and what factors influenced return to activities. We used a mixed-method approach that involved two phases: a questionnaire (n = 8), and subsequent interviews of some participants (n = 3). Participants were ages 14–17 (M = 15.4) and had had posterior instrumentation and fusion for scoliosis in the past 2 years.

Results

Some patients were cautious about return to activities, either because of emotional or medical reasons. However, in many instances, participants returned to physical activities earlier than was recommended, primarily for emotional and social reasons.

Immobilization in External Rotation and Abduction Versus Arthroscopic Stabilization After First-Time Anterior Shoulder Dislocation: A Multicenter Randomized Controlled Trial

BACKGROUND

Treatment of first-time shoulder dislocation (FSD) is a topic of debate. After high rates of recurrent instability after nonoperative management were reported in the literature, primary repair of FSD significantly increased. At the same time, new concepts were proposed that had promising results for immobilization in external rotation (ER) and abduction (ABD).

PURPOSE

The aim of this study was to evaluate the recurrence rates (primary outcome) and clinical outcomes (secondary outcome parameters) of immobilization in ER+ABD versus arthroscopic primary stabilization after FSD.

STUDY DESIGN

Randomized controlled trial; Level of evidence, 1.

METHODS

In a multicenter randomized controlled trial, patients with FSD were randomized to either treatment with immobilization in 60° of ER plus 30° of ABD (group 1) or surgical treatment with arthroscopic Bankart repair (group 2). Clinical evaluation was performed 1, 3, and 6 weeks as well as 6, 12, and 24 months postoperatively or after reduction, including range of motion, instability testing, subjective shoulder value, Constant-Murley score, Rowe score, and Western Ontario Shoulder Instability Index. Recurrent instability events were prospectively recorded.

RESULTS

Between 2011 and 2017, a total of 112 patients were included in this study. Of these, 60 patients were allocated to group 1 and 52 to group 2. At the 24-month follow-up, 91 patients (81.3%) were available for clinical examination. The recurrence rate was 19.1% in group 1 and 2.3% in group 2 (P = .016). No significant differences were found between groups regarding clinical shoulder scores (P > .05). Due to noncompliance with the immobilization treatment protocol, 4 patients (6.7%) were excluded.

CONCLUSION

Immobilization in ER+ABD versus primary arthroscopic shoulder stabilization for the treatment of FSD showed no differences in clinical shoulder scores. However, recurrent instability was significantly higher after nonoperative treatment.

Recurrence and Revision Rates With Arthroscopic Bankart Repair Compared With the Latarjet Procedure in Competitive Rugby Players With Glenohumeral Instability and a Glenoid Bone Loss <20

BACKGROUND

There is a lack of evidence in the literature comparing outcomes between the arthroscopic Bankart repair and the Latarjet procedure in competitive rugby players with glenohumeral instability and a glenoid bone loss <20%.

PURPOSE

To compare return to sport, functional outcomes, and complications between the arthroscopic Bankart repair and the Latarjet procedure in competitive rugby players with glenohumeral instability and a glenoid bone loss <20%.

STUDY DESIGN

Cohort study; Level of evidence, 3.

METHODS

Between June 2010 and February 2018, 130 competitive rugby players with anterior shoulder instability were operated on in our institution. The first 80 patients were operated on with the arthroscopic Bankart procedure and the other 50 with the open Latarjet procedure. Return to sport, range of motion (ROM), the Rowe score, and the Athletic Shoulder Outcome Scoring System (ASOSS) were used to assess functional outcomes. Recurrences, reoperations, and complications were also evaluated.

RESULTS

In the total population, the mean follow-up was 40 months (range, 24-90 months) and the mean age was 24.2 years (range, 16-33 years). Ninety-two percent of patients were able to return to rugby, 88% at their preinjury level of play. Eighty-nine percent of patients in the Bankart group and 87% in the Latarjet group returned to compete at the same level (P = .788). No significant difference in shoulder ROM was found between preoperative and postoperative results. The Rowe and ASOSS scores showed statistical improvement after operation (P < .01). No significant difference in functional scores was found between the groups The Rowe score in the Bankart group increased from a preoperative mean (± SD) of 41 ± 13 points to 89.7 points postoperatively, and in the Latarjet group, from a preoperative mean of 42.5 ± 14 points to 88.4 points postoperatively (P = .95). The ASOSS score in the Bankart group increased from a preoperative mean of 53.3 ± 3 points to 93.3 ± 6 points postoperatively, and in the Latarjet group, from a preoperative mean of 53.1 ± 3 points to 93.7 ± 4 points postoperatively (P = .95). There were 18 recurrences (14%). The rate of recurrence was 20% in the Bankart group and 4% in the Latarjet group (P = .01). There were 15 reoperations (12%). The rate of reoperation was 16% in the Bankart group and 4% in the Latarjet group (P = .03). There were 6 complications (5%). The rate of complications was 4% in the Bankart group and 6% in the Latarjet group (P = .55). The proportion of postoperative osteoarthritis was 10% in the Bankart group (8/80 patients) and 12% (6/50 patients) in the Latarjet group (P = .55).

CONCLUSION

In competitive rugby players with glenohumeral instability and a glenoid bone loss <20%, both the arthroscopic Bankart repair and the Latarjet procedure produced excellent functional outcomes, with most athletes returning to sport at the same level they had before the injury. However, the Bankart procedure was associated with a significantly higher rate of recurrence (20% vs 4%) and reoperation (16% vs 4%) than the Latarjet procedure.

High Rate of Return to Sports and Low Recurrences With the Latarjet Procedure in High-Risk Competitive Athletes With Glenohumeral Instability and a Glenoid Bone Loss <20

Purpose

To analyze return to sports, functional outcomes, and complications following the Latarjet procedure in competitive athletes with anterior glenohumeral instability and glenoid bone loss <20%.

Methods

All the included patients were operated between 2010 and 2016. The inclusion criteria were competitive athletes with anterior glenohumeral instability, a glenoid bone defect <20% who participated in contact sports, forced overhead sports, or had a previous failed Bankart repair and had a minimum 2 years’ follow-up. Return to sports, range of motion (ROM), the Rowe score, and the Athletic Shoulder Outcome Scoring System score were used to assess functional outcomes. Complications and bone consolidation were also evaluated.

Results

A total of 65 athletes were included in the study. The mean follow-up was 53 months (±13), and the mean age was 23.9 years (range, 16-31 years). Overall, 94% were able to return to sports and 84% returned at the same level. No significant difference in shoulder ROM was found between preoperative and postoperative results. The Rowe and Athletic Shoulder Outcome Scoring System scores showed statistical improvement after operation (P < .001). No significant difference in shoulder ROM and functional scores was found between primary and revision cases. The total complication rate was 11% and the revision rate was 1.5% The recurrence rate was 4.6%. The bone block healed in 95% of the cases.

Conclusions

In high-risk competitive athletes with anterior glenohumeral instability and glenoid bone loss <20%, the Latarjet procedure resulted in excellent functional outcomes, with most of the patients returning to sports and at the same level they had before injury with a low rate of recurrences

Postoperative Recurrence of Instability After Arthroscopic Bankart Repair for Shoulders With Primary Instability Compared With Recurrent Instability: Influence of Bipolar Bone Defect Size

BACKGROUND

In shoulders with traumatic anterior instability, a bipolar bone defect has recently been recognized as an important indicator of the prognosis.

PURPOSE

To investigate the influence of bipolar bone defects on postoperative recurrence after arthroscopic Bankart repair performed at primary instability.

STUDY DESIGN

Cohort study; Level of evidence, 3.

METHODS

The study group consisted of 45 patients (45 shoulders) who underwent arthroscopic Bankart repair at primary instability before recurrence and were followed for at least 2 years. The control group consisted of 95 patients (95 shoulders) with recurrent instability who underwent Bankart repair and were followed for at least 2 years. Glenoid defects and Hill-Sachs lesions were classified into 5 size categories on 3-dimensional computed tomography and were allocated scores ranging from 0 for no defect to 4 for the largest defect. The shoulders were classified according to the total score for both lesions (0-8 points). The postoperative recurrence rate was investigated for each score of bipolar bone defects and was compared between patients with primary instability and patients with recurrent instability. The same analysis was performed for the age at operation (<20 years, 20-29 years, or ≥30 years) and for the presence of an off-track Hill-Sachs lesion.

RESULTS

Bipolar bone defects were smaller in shoulders with primary instability (mean ± SD defect score, 1.4 ± 1.5 points) than in those with recurrent instability (3.6 ± 1.9 points) and were larger in older patients than in younger patients at the time of primary instability. The postoperative recurrence rate was low (6.7%) in shoulders with primary instability regardless of the size of the bipolar bone defect and the patient's age, whereas the postoperative recurrence rate was high (23.2%) in shoulders with recurrent instability, especially among patients younger than 20 years with bipolar bone defects of 2 points or greater. An off-track Hill-Sachs lesion was found in only 1 patient in the oldest age group (2.2%) at primary instability, but it was found in 19 patients (20%) at recurrent instability, including 14 patients younger than 30 years. Among patients with an off-track lesion, the postoperative recurrence rate was significantly higher in patients younger than 20 years with recurrent instability (recurrence rates: <20 years, 71.4%; 20-29 years, 14.3%; ≥30 years, 0%).

CONCLUSION

The recurrence rate was consistently low in patients with primary instability and was significantly influenced by bipolar bone defect size and patient age in patients with recurrent instability.

It's Not All About Redislocation: A Systematic Review of Complications After Anterior Shoulder Stabilization Surgery

BACKGROUND

The surgical treatment of recurrent shoulder instability has evolved in recent years to include a variety of soft tissue and bone block procedures, undertaken with either an open or arthroscopic approach. Although the utilization of such techniques has rapidly expanded, the associated risk of complications remains poorly defined. This information is vital for clinical decision making and patient counseling.

PURPOSE

To quantify the complication rate associated with all types of surgery for anterior glenohumeral joint dislocation.

STUDY DESIGN

Systematic review.

METHODS

A systematic search was undertaken of studies reporting complications from anterior shoulder stabilization surgery. Inclusion criteria were studies published in English between 2000 and 2017 with a minimum 2-year follow-up. Methodological quality of the included studies was assessed with the Methodological Index for Non-Randomized Studies criteria. Complication rates for all undesirable events contributing to the patient outcome were extracted and cumulative rates calculated.

RESULTS

Out of 1942 references, 56 studies were included, totaling 4362 procedures among 4336 patients. Arthroscopic soft tissue repair had a complication rate of 1.6% (n = 2805). When repair was combined with arthroscopic remplissage, the rate was 0.5% (n = 219). Open soft tissue repair had a complication rate of 6.2% (n = 219) and open labral repair with remplissage, a rate of 2.3% (n = 79). An open bone block procedure had a complication rate of 7.2% (n = 573) and an arthroscopic bone block procedure, a rate of 13.6% (n = 163).

CONCLUSION

This large systematic review demonstrates the overall complication rates (not purely recurrence rates) in modern shoulder stabilization surgery. With the growing interest in bone block stabilization procedures, including those performed arthroscopically, surgeons should be aware of the 10-fold increase in complications for these procedures over soft tissue arthroscopic surgery and counsel their patients accordingly.
