Total ankle arthroplasty results using fixed bearing CT-guided patient specific implants in posttraumatic versus nontraumatic arthritis.

Background: Patients who undergo total ankle arthroplasty (TAA) for end-stage posttraumatic ankle osteoarthritis have previously reported more complications and lower satisfaction than those with non-traumatic etiologies. The purpose of this study was to evaluate clinical and radiographic outcomes in these two patient groups after TAA using a newer generation implant.

Methods: Patients underwent TAA with a third generation implant using CT-based patient-specific cutting guides.

Arthroscopic Management of Synovial Chondromatosis of the Ankle Joint: A Systematic Review of the Literature.

Background: Synovial chondromatosis (SC) of the ankle is a rare disorder in which metaplastic proliferation of synovia, tendon sheaths, and/or bursae leads to the formation of loose cartilaginous bodies within the joint space. While SC itself is a benign condition, its sequelae can be chronic and debilitating if left untreated, or if there is postoperative recurrence. Arthritic degeneration and malignant transformation to chondrosarcoma are among the more serious complications in the natural history of the disease; the latter occurs in approximately 5% of cases.

Posterior Hoffa's fat pad impingement secondary to a thickened infrapatellar plica: a case report and review of the literature.

We report a case of posterior hoffitis in a middle-aged woman with no prior history of significant major trauma. Her symptoms of anterior knee pain and limited extension failed conservative measures. Preoperative magnetic resonance imaging demonstrated a significantly thickened infrapatellar plica tethering Hoffa's fat pad in the anterior interval of the knee.
