Effect of Patellar Morphology on Total Knee Arthroplasty in Patients with Patellofemoral Joint Osteoarthrosis Based on Wiberg Classification
Objective To investigate the effect of different patellar morphology on the efficacy of total knee arthroplasty(TKA)in knee osteoarthritis patients with patellofemoral joint osteoarthrosis based on patellar Wiberg classification.Methods A total of 184 patients who underwent initial TKA from January 2018 to January 2022 and met the criteria were selected as the study objects.The patients were divided into three groups by Wiberg classification of preoperative patellar morphology:W1(52 cases),W2(93 cases)and W3(39 cases).The incidence of anterior knee pain(AKP),visual analog scale(VAS),Oxford Knee Score(OKS),Feller score and imaging data of patients before and after surgery were collected and compared among the three groups.Results At the last follow-up,all the observation indexes of the three groups were significantly improved as compared with those before operation(P＜0.05).At 12th month after surgery,the degree and incidence of postoperative AKP in the W3 group were significantly higher than those in the W1 and W2 groups.Meanwhile,OKS Q12 in the W1 and W2 groups was significantly better than that in the W3 group,and Feller scores in the W1 and W2 groups were significantly higher than those in the W3 group(P＜0.05).Conclusion The degree of knee pain,the incidence of AKP,and improvement of patellofemoral joint function of patients with Wiberg type Ⅰ and Ⅱ patella after TKA surgery are superior to those with Wiberg type Ⅲ patella.However,whether some WibergⅢpatients with severe wear are suitable for TKA needs further study.
