Patellofemoral Joint Overstuffing and its Effect on Clinical Outcome in Total Knee Arthroplasty without Patella Resurfacing
Abstract: Objective: To analyze the influencing factors for patellofemoral joint (PFJ) overstuffing following total knee arthroplasty (TKA) without patella resurfacing, and explore the effect of PFJ overstuffing on clinical efficacy. Methods: Retrospective analysis was conducted on 84 patients with end-stage knee osteoarthritis who underwent TKA without patella resurfacing at our hospital between March 2023 and October 2024. In this study, PFJ overstuffing was defined as a postoperative PFJ distance greater than 1 mm compared to the preoperative measurement and the occurrence of PFJ was counted. The patients were divided into the overstuffing group (n=55) and the non-overstuffing group (n=29) to count the patellar thickness and thickness of femoral anterior condyle in all patients before and after surgery, and analyze the influencing factors for postoperative PFJ overstuffing in such patients. Patients were followed up for 1 year to compare the recovery time of postoperative pain, score of visual analogue scale (VAS) and flexion activity. Results: There was no significant difference in patellar thickness between preoperative and postoperative measurements of the patients (P>0.05). However, the thickness of the femoral anterior condyle and the PFJ distance after surgery increased significantly compared with those before surgery (P0.05). Spearman rank correlation analysis indicated females tend to have a lower preoperative thickness of the femoral anterior condyle (r=-0.424, P
