Abstract

Purpose: When conservative measures are unsuccessful in improving pain and function in patients with knee osteoarthritis, a unicompartmental or total knee arthroplasty may be considered. Choosing between the two can be a difficult decision without unbiased and credible evidence. The goal of this paper is to investigate the outcomes of a unicompartmental knee arthroplasty on pain and function compared with a total knee arthroplasty within one year in patients with knee osteoarthritis.

Methods: A literature search has been performed using Google Scholar, PubMed, and Summon since 2018. From 16,700 sources, five studies were selected using inclusion and exclusion criteria. These studies include one systematic review, three prospective cohort studies, and one retrospective cohort study. These studies compared the Knee Society Score, Numerical Pain Rating Scale, Oxford Knee Score, UCLA activity-level scores, revision rate, and annual revision rate. Studies must have been published from 2018 to 2023, have a minimum of one year follow up, and have isolated osteoarthritis.

Results: After a minimum of one year follow up, patients receiving a unicompartmental knee arthroplasty had a larger improvement in patient-reported outcomes whereas patients receiving a total knee arthroplasty had lower revision rates and longer implant survivorship.

Conclusions: After a minimum of one year follow-up, unicompartmental knee arthroplasties led to improved patient-reported pain and functional outcomes whereas total knee arthroplasties had improved implant survivorship and decreased revision rates.

Keywords: total knee arthroplasties, unicompartmental knee arthroplasties, pain and function, Knee Society Score, Numerical Pain Rating Scale, UCLA Activity-Level Score, Oxford Knee Score, and annual revision rate.
