Total Knee Revision Using the Midvastus Approach: A Case Report.

Total knee arthroplasty (TKA) is a common procedure for managing severe knee osteoarthritis. However, component loosening continues to be a common issue, frequently requiring revision surgery. Although the medial parapatellar (MPP) approach is commonly used due to the broad access it provides, it may disrupt the extensor mechanism and reduce blood flow to the patella. We present a case of a 62-year-old woman who required revision TKA (RTKA) on the left knee due to tibial component loosening seven years after her initial surgery, which had been performed via the MPP approach. We have used the midvastus (MV) approach to preserve the quadriceps tendon. This case highlights the MV approach as a viable alternative in RTKA, offering adequate exposure while minimizing soft tissue damage.
