Early Patellar Related Complications after Total Knee Arthroplasty

Abstract

Background and Aim: Total knee arthroplasty (TKA) surgeries are growing annually. Reporting the early patellar related complications in patients undergoing TKA was the aim of this study.

Patients and Methods: In this prospective study, medical history, clinical and  radiological evaluation, and planning and simulation were performed preoperatively. The Knee Society Score was used to assess the  clinical outcomes. Early patellar related complications were assessed.

Results: This study included thirty patients with a mean age of  60.73±6.84 years and most of them were ladies (76.7%) with male to female ratio was 1: 3.29. A significant improvement in the mean  Functional Score section of Knee Society Score, from 62.6±2.35 preoperatively to 90.0±0 postoperatively, with a mean follow-up period of  six months. Additionally, a significant improvement in flexion deformity was detected. (10%) of cases showed anterior knee pain due to  patella-femoral origin, patellar clunk was seen in (3.33%), patella alta in (10%), and none of them reported rotational malalignment,  infection, venous thromboembolism (VTE), or stiffness.

Conclusions: TKA with medial parapatellar approach achieves excellent clinical  and radiological outcomes with a low incidence of early patellar related complications such as persistent pain and patella alta or clunk
