Long-Term Outcomes of Osteochondral Allograft with Osteogenic Protein-1 Augmentation: A Twelve-Year Follow-Up.

Background: Osteochondral lesions (OCLs) can significantly impact functional status and activities of daily living. Weightbearing joints are disproportionately affected due to considerable biomechanical forces in these areas. Various biologic reconstructive procedures such as microfracture, osteochondral autograft transfer (OATS) or allograft transplantation (OCA), and matrix-induced autologous chondrocyte implantation (MACI) are utilized by surgeons to treat OCLs.

Shoulder Injury Related to Vaccine Administration.

Shoulder injury related to vaccine administration (SIRVA) is a recognized complication and possible source of morbidity associated with incorrectly administered intramuscular deltoid vaccinations. As this site is commonly used for intramuscular injection, both clinicians and vaccine administrators should be familiar with SIRVA to minimize risk and monitor for its clinical presentation. A 49-year-old male presented with shoulder pain that began 1 day after intramuscular administration of an influenza vaccine and point tenderness near the site of injection.

Recurrent Nontuberculous Mycobacterial Tenosynovitis.

Nontuberculous mycobacteria are an uncommon pathogen for musculoskeletal infection and are difficult to treat because of delays in diagnosis, prolonged treatment requiring both antimycobacterial therapy and surgical debridement, and high rates of resistance to antimycobacterial therapy. We report the case of an 88-year-old male with recurrent complex tenosynovitis despite receiving multiple courses of pharmacologic therapy and surgical debridement. Nontuberculous mycobacterial musculoskeletal infections can be difficult to diagnose and equally difficult to treat.
