Background: Arthroscopic treatment has evolved to become the primary surgical option in the management of anterior shoulder instability as studies show comparable outcomes between open and arthroscopic techniques., Objective: To evaluate prospectively the results of our institutional database for arthroscopic Bankart repairs at a minimum 2-year follow-up for patients with anterior instability treated with suture anchors., Study Design: Case series; Level of evidence, 4., Methods: Eighty-three consecutive patients underwent arthroscopic Bankart repair with suture anchors. The mean age at the time of surgery was 33 years (range, 15-55 years). At an average follow-up of 33 months (range, 24-49 months), 73 patients (61 males, 12 females) were assessed with outcomes scores including the American Shoulder and Elbow Surgeons, L'Insalata, and visual analog scores. The rate of recurrent instability, range of motion, and risk factors for postoperative recurrence were evaluated., Results: Thirteen patients (18%) suffered a recurrence after surgery. Seven patients (10%) had a subsequent dislocation and 6 (8%) a subluxation event or apprehension. Six of the 13 had a traumatic event that resulted in recurrent episodes of instability. Revision surgery was needed for 2 patients (3%) for instability and 2 for postoperative shoulder stiffness. On average there was no significant loss of external rotation postoperatively (average, 71 degrees pre- and postoperatively). The American Shoulder and Elbow Surgeons and L'Insalata scores improved from 75.4 to 94.9 and 66.5 to 90.9, respectively (P <.0001). The visual analog score improved from 2.4 to 0.4 (P <.001). Patient age under 25, ligamentous laxity, and the presence of a large (>250 mm(3)) Hill-Sachs lesion were associated with recurrence (P <.05). Patients under age 20 had a 37.5% recurrence rate., Conclusion: In the arthroscopic treatment of anterior instability, identification of risk factors for recurrence allows for appropriate patient counseling and consideration of open stabilization. In our series, patients under age 25, with ligamentous laxity, and with a large (>250 mm(3)) Hill-Sachs lesion were at the greatest risk of recurrence.

This clinical study was performed to document the prevalence of deep vein thrombosis (DVT) after prosthetic shoulder replacement surgery. We prospectively followed 100 consecutive shoulder arthroplasty procedures (total shoulder replacement in 73 and hemiarthroplasty in 27) in 44 male and 56 female patients for 12 weeks (mean age, 67 years; range, 17-88 years). Risk factors for venous thromboembolic disease were assessed preoperatively and postoperatively. A 4-limb surveillance color flow Doppler ultrasound was performed at 2 days (100 patients) and 12 weeks (50 patients randomly selected) after surgery, and the presence and location of DVT were recorded. Postoperative symptomatic or fatal pulmonary emboli (PE) were also recorded. The overall prevalence of DVT was 13.0%, consisting of 13 DVTs in 12 patients. These included 6 ipsilateral and no contralateral upper extremity DVTs and 5 ipsilateral and 2 contralateral lower extremity DVTs. The prevalence of DVT was 10.0% (10/100) at day 2 after surgery and 6.0% (3/50) at week 12 after surgery. The incidence of symptomatic nonfatal PE was 2.0% (2/100), and that of fatal PE was 1.0% (1/100). Risk factors associated with venous thromboembolic disease did not reach statistical significance because of the small study population sample size. At our institution, the prevalence of DVT after reconstructive shoulder arthroplasty was 13.0%, a rate comparable to that after hip arthroplasty (10.3%) but lower than that after knee arthroplasty (27.2%). Shoulder arthroplasty surgeons should be aware of the potential risk of perioperative thromboembolic complications in both the acute and subacute postoperative periods.
