Although performing UKA on both knees in a single sitting can offer logistical benefits, there is limited data comparing its safety and clinical outcomes with unilateral procedures. The objective of this study was to compare the mid-term functional outcomes, recovery parameters, and complication rates between one-stage single-sitting bilateral and unilateral UKA.\n\nMaterials and Methods: This observational study included 256 patients diagnosed with medial compartment OA who underwent either one-stage single-sitting bilateral UKA (n = 134) or unilateral UKA (n = 122). Functional outcomes were evaluated using the Oxford Knee Score (OKS), pain levels through the Visual Analog Scale (VAS), range of motion (ROM), post-operative satisfaction, and time to return to regular activities over a 5-year follow-up period.\n\nResults: Significant improvements in OKS, ROM, and VAS scores were observed in both groups (P &lt; 0.001). Patients undergoing one-stage single-sitting bilateral UKA required fewer physiotherapy sessions (17.6 vs. 21.4, P &lt; 0.001) and returned to daily activities earlier (5.2 vs. 6.4 weeks, P &lt; 0.001), without increased hospital stay or complications.\n\nConclusion: One-stage single-sitting bilateral UKA appears to be a safe and effective treatment strategy for carefully selected patients with medial compartment OA, offering comparable safety and enhanced functional recovery compared to unilateral procedures.\n\nKeywords: Unicompartmental knee arthroplasty, one-stage single-sitting bilateral unicompartmental knee arthroplasty, medial compartment osteoarthritis, functional outcomes, patient satisfaction.<\/jats:p>","DOI":"10.13107\/jocr.2026.v16.i04.7148","type":"journal-article","created":{"date-parts":[[2026,4,9]],"date-time":"2026-04-09T08:07:47Z","timestamp":1775722067000},"page":"351-358","source":"Crossref","is-referenced-by-count":0,"title":["Mid-term Functional Outcomes Following  One-stage Single-Sitting Bilateral and Unilateral Unicompartmental Knee Arthroplasty: A 5-year Prospective Cohort Study"],"prefix":"10.13107","volume":"16","author":[{"given":"Amyn M","family":"Rajani","sequence":"first","affiliation":[{"name":"OAKS Clinic, Mumbai, Maharashtra, India,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rajesh","family":"Garg","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Thumbay University Hospital, Ajman, UAE."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Clevio","family":"Desouza","sequence":"additional","affiliation":[{"name":"OAKS Clinic, Mumbai, Maharashtra, India,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vishal","family":"Kulkarni","sequence":"additional","affiliation":[{"name":"OAKS Clinic, Mumbai, Maharashtra, India,"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"5271","published-online":{"date-parts":[[2026]]},"container-title":["Journal of Orthopaedic Case Reports"],"original-title":[],"deposited":{"date-parts":[[2026,4,9]],"date-time":"2026-04-09T08:07:51Z","timestamp":1775722071000},"score":1,"resource":{"primary":{"URL":"https:\/\/jocr.co.in\/wp\/2026\/04\/mid-term-functional-outcomes-following-simultaneous-bilateral-and-unilateral-unicompartmental-knee-arthroplasty-a-5-year-prospective-cohort-study\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2026]]},"published-print":{"date-parts":[[2026]]}},"URL":"https:\/\/doi.org\/10.13107\/jocr.2026.v16.i04.7148","relation":{},"ISSN":["2321-3817"],"issn-type":[{"value":"2321-3817","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026]]}}}
