Retention treatment after periprosthetic total hip arthroplasty infection.

Purpose: The purpose of this study was to compare infection control rates between implant retention and two-stage revision and assess the effectiveness of retention treatment in THA.

Methods: Twenty-eight debridements with implant retention (retention group) and 65 staged revisions (removal group) were retrospectively analysed and risk factors that can contribute to failure of infection control were explored.

Results: For the retention and removal groups, infection control rates were 50% and 78% after initial treatment, and 68% and 82% at latest follow-up, respectively.

Do commonly reported outcome measures reflect patient satisfaction after revision hip arthroplasty?

The purpose of this study was to determine which commonly reported outcome measures best correlated with patient satisfaction after revision hip arthroplasty and to identify factors unrelated to hip status that may also play a role. From our institutional database, we identified 78 patients (80 hips) who underwent revision total hip arthroplasty and collected follow-up data. Patients with moderate or severe pain and those with limited walking ability reported significantly lower satisfaction scores.
