Introduction: This systematic review and meta-analysis compared the revision rates, complications, and outcomes in anatomic total shoulder arthroplasty (aTSA) and reverse TSA (rTSA) performed for primary glenohumeral osteoarthritis in patients aged over 70 years without a full-thickness rotator cuff tear.

Materials And Methods: We performed a systematic literature search identifying comparative studies meeting the above patient criteria and published from January 2010 to May 2022 from 3 databases: MEDLINE, EMBASE, and Cochrane Library. We performed the systematic review in accordance with PRISMA guidelines and the study was prospectively registered on PROSPERO.

Case: We describe a case of a traumatic superior dislocation of the sternoclavicular joint (SCJ) due to an isolated rupture of the costoclavicular ligament (CCL). A magnetic resonance imaging (MRI) scan demonstrated the CCL rupture with preservation of the anterior and posterior SCJ ligaments. This was successfully treated with an isolated hamstring tendon reconstruction of the CCL, resulting in a satisfactory outcome at 1 year after the procedure.

Introduction: Stiffness following total knee arthroplasty (TKA) is a challenging complication and can result in a poor functional outcome. There is considerable debate concerning the definition, work-up, and optimal management of this complication. The aim of this study was to record the definition of stiffness, management practices, and expectations of outcome among surgeons from an international community using a peer-reviewed questionnaire.

Avulsion fracture of the tibial tuberosity is an infrequent injury in adolescents and an extremely rare occurrence in adults. We describe the case of an 86-year-old gentleman presenting after a fall, sustaining injury to the left knee. Radiographs of the left knee showed avulsion fracture of the tibial tuberosity.

Subscapular abscess is an uncommon condition which requires early recognition followed by prompt surgical intervention. We present a case of spontaneous subscapular abscess following blunt trauma to the shoulder in a patient with a history of recurrent superficial soft tissue infections, in which Panton-Valentine leukocidin-producing was identified as the infectious agent. This strain due to its virulence can lead to fatal infections in otherwise healthy individuals; therefore, a high index of suspicion is needed to investigate with an MRI to rule out abscess formation in a patient with acute shoulder girdle pain and negative joint aspirate.

Introduction: Septic arthritis of the sternoclavicular (SC) joint is a rare condition. Typically, it presents in patients with risk of infection and is usually unilateral. In this report, we describe a case of spontaneous bilateral sternoclavicular joint infection of an otherwise healthy adult.

Spinal metastases may present in a myriad of ways, most commonly back pain with or without neurology. We report an unusual presentation of isolated atypical chest pain preceding metastatic cord compression, secondary to penile carcinoma. Spinal metastasis from penile carcinoma is rare with few cases reported.

Stiffness following total knee arthroplasty (TKA) is a debilitating condition for the patient with limitation of functional outcome. There are various causes of stiffness, which can be classified as pre-operative, per-operative and post-operative. Arthrofibrosis is one of the causes, which can be managed in different ways, and manipulation under anaesthesia (MUA) is routinely performed as the first line of management.
