Medial Parapatellar versus Lateral Parapatellar Approach in Total Knee Arthroplasty in Valgus Deformity

Abstract

Although TKA is one of the most commonly performed operations in adult reconstructive surgery. The surgical approaches in primary TKA remain controversial. There are proponents for medial parapatellar approach and proponents for lateral parapatellar approach. In our study, we aimed to compare the different effects of medial parapatellar approach and lateral parapatellar approach in total knee arthroplasty. 40 patients (46 knees) who are candidates for TKA were enrolled in a pilot comparative randomized clinical trial using a posterior-stabilized TKA. Evaluations were done preoperatively and after 1, 3, 6 and 12 months. Evaluation using Knee Society Score (KSS) and functional knee society score were measured.
