Abstract:

BACKGROUND: There is consistency of conclusions on whether the patella replacement should be performed in total knee arthroplasty.
OBJECTIVE: To comparatively observe whether the patella replacement should be performed in total knee arthroplasty.
METHODS: A total of 56 cases (60 knees) with knee osteoarthritis were selected from Yancheng City No.1 People’s Hospital from July 2009 to April 2012, and divided into patella replacement group and non-replacement group.
RESULTS AND CONCLUSION: At 3 months after total knee arthroplasty, the Hospital for Special Surgery score, patella score, activity and Q angle in patella replacement group were lower than those in the non-replacement group (P < 0.05), while there was no significant difference of postoperative anterior knee pain score and knee valgus angle between two groups (P > 0.05). Intraoperative reasonable patellar treatment can effectively improve the trajectory of the patellofemoral joint, significantly reduce the patellar complications. For the patients with patellofemoral match and a good line of force, to retain the patella in total knee arthroplasty can improve joint function recovery, and the overall effect of patella replacement is better than that of non-replacement.
