Summary: The subvastus approach is an alternative to the standard medial parapatellar approach in TKA which can be used with equally good results

Abstract:

Introduction

The subvastus and medial parapatellar approaches are 2 commonly performed techniques in total knee arthroplasty, but the optimal approach for total knee arthroplasty remains controversial.The medial parapatellar approach in total knee arthroplasty is more common, but the subvastus approach is less insulting to the quadriceps. METHODS: In a prospective randomized study, we compared the clinical and radiological results of primary TKA using a mini-subvastus approach or a standard medial parapatellar approach in 100 patients. The mini-subvastus approach was used on 50 patients(group I) and the parapatellar approach on 50 patients (group II). Mean follow of patients was 24 months ( 20-36 months

Results

Assessment of the results of both operating approaches was based on functional, clinical Knee Society Score, and pain (visual analog scale).No statistically significant differences existed between assessed end points in both groups at 24- and 52-weeks, and 24-months postoperatively. The subvastus approach has given patients better early clinical results; however, at longer follow-up, both groups had similar outcomes. CONCLUSION:The subvastus approach is an alternative to the standard medial parapatellar approach in TKA which can be used with equally good results
