Computer-assisted total knee replacement leads to better postoperative outcomes: 3 study findings

Orthopedic

Computer-assisted total knee replacement provided greater pain relief and restored function two years postoperatively compared to conventional total knee replacement, according to a study in The Journal of Bone and Joint Surgery.

Here are three things to know:

1. The randomized, controlled trial assessed 172 patients who underwent computer-assisted or conventional total knee replacement. Almost all — 97 percent — answered all patient-reported outcome measures.

2. Study authors assessed surgical outcomes using the Outcome Measures in Rheumatology-Osteoarthritis Research Society International criteria to calculate responder rates, which are divided into high responders, moderate responders and non-responders.

3. The computer-assisted group had significantly more improvement than the conventional group and significantly more high responders at two years postoperatively.
