Successful salvage of a recurrently dislocating Oxford medial unicompartmental bearing.
Dislocation of the bearing of the Oxford medial unicompartmental arthroplasty is a rare but serious complication. We report the case of a 48-year-old woman with a classic anteromedial arthritis who had 2 bearing dislocations within the first 3 months after index surgery. ⋯ After arthroscopic resection of the osteophyte, she has retained her original components with no further dislocations or signs of impending failure 7 years later. This case report emphasizes the importance of osteophyte removal from the back of the femoral condyle during an Oxford unicompartmental arthroplasty.

Pain management after total hip arthroplasty has improved dramatically in the past decade. However, most protocols use opioid medications for pain control. In the current study, 100 patients were prospectively selected to receive a traditional narcotic-based patient-controlled analgesia protocol or a nonnarcotic oral protocol for pain management after primary total hip arthroplasty. ⋯ The nonnarcotic oral group showed lower mean pain scores during the first 24 hours after surgery. The satisfaction rate was high in both groups. Both protocols provided adequate pain control after total hip arthroplasty; the nonnarcotic pain management protocol resulted in significantly decreased opioid consumption and fewer adverse effects.
