Effects of Denosumab on Bone Microarchitecture After Total Knee Arthroplasty

Single Dose Subcutaneous Injections of Denosumab for Patients Underwent Cemented Total Knee Arthroplasty. A Randomized Controlled Study on the Effects on Bone Microarchitecture, Skeletal Muscle, Cartilage and Synovium

This study evaluates single dose of Denosumab in decreasing systemic and periprosthetic bone resorption after Total Knee Arthroplasty compared to placebo in 60 patients (30 placebo and 30 Denosumab) within 2 months after surgery. This study also evaluates the anti-RANKL effect of single dose of Denosumab in serum, skeletal muscle, synovium, fat, and cartilage.
