The influence of severe knee varus and patellofemoral joint degeneration on outcomes following fixed-bearing medial robotic-assisted unicompartmental knee arthroplasty: a minimum of 18-month follow-up

This is the first study demonstrating that preoperative radiographic severe knee varus, mild-to-moderate PFJ OA, and malalignment of the PFJ do not adversely influence early outcomes after fixed-bearing medial RA-UKA. However, the relatively short follow-up period limits the assessment of complications, implant survivorship, and mid- to long-term functional outcomes, particularly in patients with severe varus deformity. Therefore, the current findings apply only to early postoperative outcomes.
