Knee Arthroplasty without Metal Augmentations in Patients with Major Tibial Defects: A Retrospective Study

Knee arthroplasty procedures improve pain, function, stability, and appearance of the limb. Total knee arthroplasty (TKA) in severe, long-standing osteoarthritis (OA) with large medial tibial defects could be a challenge. This paper looks at TKA outcomes when large tibial defects are managed without metal wedges or stems. TKA cases done for OA with tibial defects of 15-25 mm, without any metal wedge or stem from 2004 to 2017 by a single surgeon in Shiraz, Iran, were clinically and radiographically evaluated. The preoperative questionnaires of SF36, WOMAC, KSS, and radiographs were compared with the follow-up assessments of the same parameters. Data were analyzed by R programming language using student test, ANOVA, and Kruskal-Wallis. P
