Abstract Background: Both total knee arthroplasty (TKA) and unicompartement knee arthroplasty (UKA) are options to manage anteromedial knee osteoarthritis. This study aim is to determine the functional outcome, time taken to walk without support and post-operative complications after either TKA or UKA in treatment of anteromedial knee osteoarthritis. Methods : A prospective randomized cohort study is performed in level 1 academic center on 60 patients with mean age 56.2 complaining of isolated anteromedial knee osteoarthritis. Thirty patients were managed by UKA (group1) while the other thirty patients were managed by TKA (group2). Diagnosis was confirmed by plain X-rays (AP standing, Lateral, skyline, stress varus and valgus views). Follow up was done for at least 12 months postoperative. Results : Mean pre-operative function KSS was 65.83 and 62.67 for group 1 and group 2 respectively. Mean functional KSS after one year was 86.3 for group 1 and 84.6 for group 2. In group 1, one patient developed lateral joint line pain and another patient developed post operative blood loss more than 400 ml , Whereas in group 2 one patient developed pattelofemoral pain and another patient developed also postoperative blood loss more than 400 ml . The mean time in which patients can walk without support was 1.6 weeks in group 1 while it was 1.93 for group 2. Conclusion : Both UKA and TKA have the same functional outcome for treatment of anteromedial knee osteoarthritis and same rate of complications but early postoperative rehabilitation is better in patients managed by UKA. Level of evidence : Level 1 |
