REGISTRY REVIEW: Partial Knee Arthroplasty in the US
Primary total knee arthroplasty (TKA) is one of the most commonly performed orthopaedic procedures in the US. The same cannot be said for partial knee arthroplasty: According 2020 Annual Report from the American Joint Replacement Registry (AJRR), unicompartmental knee arthroplasty (medial and lateral UKA) accounted for just 4.1% of knee replacements in 2019, compared with 8.2% in 2012, and patellofemoral arthroplasty decreased from a high of 1.7% in 2016 to 0.04% in 2019.
