[Factors related to anterior knee pain after total knee arthroplasty].

Objective: To investigate the incidence rate of anterior knee pain after total knee arthroplasty (TKA) and identify the related factors.

Methods: This prospective, double-blind clinical trial involved a total of 128 patients scheduled for primary ipsilateral cemented three-component TKA for osteoarthrosis. The patients were randomized into two groups to receive operations for TKA with patellar resurfacing (experimental group) or not (control).

[Two-stage revision for treatment of periprosthetic infection following hip arthroplasty].

Objective: To evaluate the efficacy and optimal re-implantation time of two-stage revision for management of periprosthetic infection following hip arthroplasty.

Methods: We retrospectively analyzed the clinical data of 15 patients (15 hip joints) undergoing two-stage ipsilateral total hip arthroplasty (THA) revision from January, 2006 to January, 2010. In the first stage, after surgical debridement and thorough removal of all the implants, a self-made Vancomycin-loaded cement spacer was implanted.
