About

The loss of muscle mass post-surgery confounds recovery efforts and leads to a delay in patient's ability to return to activities. Although the use of testosterone in aging and chronic muscle loss has been investigated, this study could prove short-term use of testosterone efficacious in preventing muscle atrophy due to surgery. We hypothesize that by bracketing an indexed knee surgery with testosterone undecanoate injections, post-surgical quadriceps muscle loss may be minimized. Determination of the effect of intra-muscular (IM) testosterone injections in preventing quadriceps muscle loss are measured by serial MRI and manual measurements of quadriceps cross-section.

Full description

This is an in vivo study using serial IM testosterone undeconate injections in participants undergoing knee surgery with limited weight bearing post-operatively which includes partial/total knee replacement, ACL reconstruction/revision, meniscal allograft transplantation and articular cartilage paste grafting. The design is a randomized, controlled, double blind, longitudinal study of intra-muscular injections of testosterone versus saline control. Pre-operative and post-operative assessments will include: serial MRIs and manual measurements of quadriceps cross-section and knee pain and function survey, KOOS. Blood analysis will be performed for therapeutic assessment and safety. The participant will receive two testosterone undeconate injections, once during their pre-operative visit and once during their 1 month visit. Timing of assessments will be pre-operative, 1-4 days post-operative and 1, 3, and 6 months. Measurement of the control group versus experimental group at all time points may identify differences in participant response to testosterone injections.
