Tension band wiring remains a common treatment for patella fractures, but complication rates are high, with unsatisfactory results. The purpose of this observation study was to evaluate clinical results and complication rates of a novel patella locking plate fixation. ⋯ The patella locking plate is a safe and effective treatment for patella fractures, including comminuted fractures. Function can be restored within six months after surgery, and the complication rate is low. Nonetheless, the implant can cause discomfort or anterior knee pain especially when kneeling, which can necessitate an implant removal.

Excision of extensive scar tissue (EEST) may be required in certain cases of revision reverse total shoulder arthroplasty (RTSA). Neurovascular structures are at a higher risk of iatrogenic direct injury in these cases. We describe a technique to expose and protect the musculocutaneous and axillary nerves in a series of revision RTSA cases that required EEST. ⋯ Complete permanent nerve injuries resulting from direct surgical trauma during revision RTSA requiring EEST can be avoided using the technique presented here. Despite proper exposition of the nerves, partial temporary neurapraxic injuries may occur. Patients who underwent this procedure experienced significant improvements in shoulder pain and function with complication rates consistent to those previously reported in revision RTSA.

The purpose of this study was to assess whether unicompartmental knee arthroplasty (UKA) results in better patient-reported and clinical outcome than total knee arthroplasty (TKA). The study hypothesis was UKA yields better patient-reported and clinical outcomes than TKA. ⋯ Our findings suggest UKA patients are less aware of their joint replacements than TKA patients for medial osteoarthritis of the knee. UKA conserves more soft tissue and bone than TKA, which may be the reason for the differences observed.
