Introduction: Total shoulder arthroplasty (TSA) and reverse TSA (rTSA) are successful treatments for end-stage shoulder arthritis. However, it is unknown whether prior arthroscopy is associated with an increased risk for revision surgery. This study investigates if undergoing a shoulder arthroscopy in the year prior to primary arthroplasty increases risk of revision surgery within 2 years.
Methods: Patients who underwent TSA or rTSA between 2005 and 2017 were identified in a natinal claims database and stratified into two cohorts: (1) individuals with a history of shoulder arthroscopy prior to arthroplasty and (2) individuals with no documented history of arthroscopy prior to arthroplasty. These cohorts were propensity matched based on demographic and comorbidity factors. Univariate analysis was used to determine differences in revision rates, aseptic loosening, periprosthetic fracture, and infection between the two cohorts.
Results: Seven hundred and eighty-eight patients were successfully matched from the two cohorts. Revision surgery (3.4% vs. 1.4%, p = 0.001) and aseptic loosening (2.2% vs. 0.8% p = 0.021) were significantly more common in the arthroscopy cohort. Periprosthetic fracture and periprosthetic infection were not found to be significantly different between cohorts.
Discussion: Shoulder arthroscopy in the year prior to shoulder arthroplasty is associated with an increased risk of complications, including revision and aseptic loosening.

The humeral head is the second most common anatomical site of osteonecrosis after the femoral head. Studies have reported satisfactory clinical outcomes after shoulder arthroplasty to treat osteonecrosis of the humeral head (ONHH). However, there are concerns regarding implant longevity in relatively young patients.

Synovial chondromatosis is an uncommon, progressive, benign condition favoring synovial metaplasia resulting from the production of cartilaginous tissue as loose bodies within the joints. In rare cases, it can affect the interior of the shoulder joint and present with pain, edema, and impaired mobility. The diagnosis is challenging, requiring imaging techniques.

Reduction and fixation of glenoid cavity fractures using arthroscopy cause little surgical trauma, allowing the complementary diagnosis and treatment of potentially associated injuries (either capsular, ligamentous or tendon lesions) with promising outcomes. The authors report a case of Ideberg type III glenoid fracture with a distal clavicle fracture which underwent percutaneous reduction and bone fixation (with Kirschner wires) using an arthroscopic technique. We describe the procedure and the outcomes after 18 years of follow-up.

Pigmented villonodular synovitis (PVNS) is rare in the shoulder, with few descriptions in the literature. We present the case of a 58-year-old female patient with no history of trauma. The patient reported pain for 2 months with no limb irradiation and presented lifting strength loss and progressive limitation of active and passive mobility.

Purpose: To determine if the fatty infiltration of rotator cuff muscles, as measured by magnetic resonance imaging (MRI) preoperatively and assessed using the Goutallier Fatty Degeneration Index (GFDI), can predict early post-operative shoulder stiffness (POSS) following rotator cuff repair (RCR).
Methods: This retrospective longitudinal cohort study included patients who underwent primary RCR, had available medical records, and underwent MRI before RCR between November 2012 and July 2022. Patients were excluded based on the following criteria: (1) preoperative shoulder stiffness, (2) additional procedures (e.
