Study summary

This study evaluates the effect of Denosumab in decreasing the periprosthetic bone resorption after Total Knee Arthroplasty compared to placebo in 60 patients (30 placebo and 30 Denosumab) within a year after surgery.

Read the detailed description

Periprosthetic bone resorption after Total Knee Arthroplasty occurs as a consequence of prosthetic implant on the bone. Some of this patients (up to 13%) develop an aseptic failure of the prosthesis needing revision surgery.

2 groups of patients are treated with Placebo and Denosumab in a double blind prospective trial. Densitometry, Knee society score (KSS), Western Ontario McMaster University Osteoarthritis Index (WOMAC) and the Medical Outcomes Study Short Form 36 (SF-36) were done in both groups at 0,3,6 and 12 months after surgery.
