Background:The high demands to the glenohumeral joint and the violent shoulder blows experienced during martial arts (MA) could compromise return to sports and increase the recurrence rate after arthroscopic stabilization for anterior shoulder instability in these athletes.Purpose:To report the functional outcomes, return to sports, and recurrences in a series of MA athletes with anterior shoulder instability treated with arthroscopic stabilization with suture anchors.Study Design:Case series; Level of evidence, 4.Methods:A total of 20 consecutive MA athletes were treated for anterior shoulder instability at a single institution between January 2008 and December 2013. Range of motion (ROM), the Rowe score, a visual analog scale (VAS), and the Athletic Shoulder Outcome Scoring System (ASOSS) were used to assess functional outcomes. Return-to-sport and recurrence rates were also evaluated.Results:The mean age at the time of surgery was 25.4 years (range, 18-35 years), and the mean follow-up was 71 months (range, 36-96 months). No significant difference in preoperative and postoperative shoulder ROM was found. The Rowe, VAS, and ASOSS scores showed statistical improvement after surgery (P < .001). In all, 19 athletes (95%) returned to sports. However, only 60% achieved ≥90% recovery after surgery. The recurrence rate was 20%.Conclusion:In this retrospective study of a consecutive cohort of MA athletes, arthroscopic anterior shoulder stabilization significantly improved functional scores. However, only 60% of the athletes achieved the same level of competition, and there was a 20% recurrence rate.

Background:There is no universally accepted definition of “contact” or “collision” sports in the literature. The few available studies evaluating contact and collision sports consider them to be synonymous. However, athletes in collision sports purposely hit or collide with each other or with inanimate objects with greater force and frequency than in contact sports, which could jeopardize functional outcomes.Purpose:To compare the functional outcomes, return to sports, and recurrences in a series of contact and collision athletes with a first-time anterior shoulder dislocation treated using arthroscopic stabilization with suture anchors.Study Design:Cohort study; Level of evidence, 2.Methods:A total of 56 athletes were enrolled in this study, including 22 contact athletes and 34 collision athletes. All athletes underwent arthroscopic shoulder stabilization using suture anchors. Range of motion, the Rowe score, a visual analog scale (VAS) for pain, and the Athletic Shoulder Outcome Scoring System (ASOSS) were used to assess functional outcomes. Return to sports and recurrences were also evaluated.Results:The mean age at the time of surgery was 22.2 years, and the mean follow-up was 62.4 months (range, 36-94 months). No significant difference in shoulder motion was found between preoperative and postoperative results or between the contact and collision groups. The Rowe, VAS, and ASOSS scores showed statistical improvement in both groups after surgery (P = .001). Patients in the contact group returned to sports significantly faster than those in the collision group (5.2 vs 6.9 months, respectively; P = .01). In all, 43 athletes (76.8%) returned to near-preinjury sports activity levels (≥90% recovery) after surgery: 86.4% of patients in the contact group and 70.6% in the collision group (P = .04). The total recurrence rate was 8.9%. There were 5 recurrences (14.7%) in the collision group and no recurrences in the contact group (P < .01).Conclusion:Arthroscopic stabilization for anterior instability of the shoulder is a reliable procedure with respect to shoulder function, range of motion, and postoperative return to sports in contact and collision athletes. Compared with the contact group (0%), the collision group yielded a higher failure rate (14.7%). Moreover, patients in the contact group returned significantly faster (5.2 vs 6.9 months, respectively) and to and more returned to preinjury or near-preinjury activity levels (86.4% vs 70.6% of patients, respectively) than patients in the collision group.

Background:Arthroscopic treatment of calcific deposits of rotator cuff tears has been described with successful results in the general population. However, despite the high frequency of this condition, there is no information in the literature regarding arthroscopic treatment of rotator cuff calcifications in athletes.Purpose:To analyze the time to return to sport, clinical outcomes, and complications of complete arthroscopic removal of intratendinous calcific deposits and repair of the tendon lesion without acromioplasty in athletes.Study Design:Case series; Level of evidence, 4.Methods:This study retrospectively evaluated 24 consecutive patients with a mean age of 36.2 years. The mean follow-up was 59 months (range, 24-108 months). Patients completed a questionnaire focused on the time to return to sport and treatment course. Pre- and postoperative functional assessment was performed using the Constant score and University of California Los Angeles (UCLA) score. Pain was assessed by visual analog scale (VAS). Radiographs and magnetic resonance imaging (MRI) were performed to evaluate the recurrence of calcifications and the indemnity of the supraspinatus tendon repair.Results:Of the 24 patients, 23 (95.8%) were able to return to sports; 91.3% returned to the same level. The mean time to return to play was 5.3 months (range, 3-9 months): 26% of patients (6/23) returned to sports in less than 4 months, 61% (14/24) returned between 4 and 6 months, and 13% (3/24) returned after the sixth month. The mean Constant score increased from 26.9 preoperatively to 89.7 postoperatively (P < .001), and the UCLA score increased from 17.3 preoperatively to 33.2 postoperatively (P < .001). Significant improvement was obtained for pain (mean VAS, 8.4 [before surgery] vs 0.6 [after]; P < .001). The overall majority (91.6%) of patients were satisfied with their result. MRI examination at last follow-up (79% of patients) showed no tendon tears.Conclusion:In athletes with calcifying tendinitis of the supraspinatus tendon with failed nonoperative treatment, complete arthroscopic removal of calcific deposits and tendon repair without acromioplasty results in significant pain relief and improvement in functional outcomes. Most patients return to the same level of proficiency regardless of the type of sport and the level of competition before injury, with 91.6% of patients satisfied with their results.
