Subcutaneous versus intraarticular indwelling closed suction drainage after TKA: A randomized controlled trial

This report has been verified by one or more authors of the original publication.

111 patients with osteoarthritis (OA) of the knee, scheduled for Total Knee Replacement, were randomized to have an indwelling intra-articular drain or a subcutaneous drain, placed at the end of TKR procedure. The subcutaneous drain was found to have comparable outcomes to the intra-articular drain; hence, the subcutaneous indwelling closed-suction drainage could be used as a safe and functional alternative to intraarticular indwelling closed-suction drainage.
