A video summary is available with the new Level-I study by Pongcharoen et al. in JBJS, “Comparison of Functional Recovery Between Unicompartmental and Total Knee Arthroplasty: A Randomized Controlled Trial.”
The investigators compared the results of the 2-minute walk test (2MWT) and the Timed Up-and-Go Test (TUG) in patients undergoing unicompartmental knee arthroplasty vs. total knee arthroplasty (UKA vs. TKA) for isolated medial knee arthritis. Patient-reported outcome measures were also assessed.
Watch the video summary:
As concluded by the authors: “The 2MWT indicated that UKA for isolated medial knee OA enabled faster recovery than TKA did at 6 weeks to 6 months, and earlier recovery was also seen with the TUG at 6 weeks to 3 months. The 2MWT and TUG results after UKA and TKA were similar to one another at 1 and 2 years.”
