The Recovery Time of Quadriceps Strength After Total Knee Arthroplasty (TKA): The Effect of Quadriceps Incision Length

October 10, 2011 updated by: Mahidol University

The Recovery Time of Quadriceps Strength After Total Knee Arthroplasty: The Effect of Quadriceps Incision Length

Minimally invasive total knee arthroplasty (MIS-TKA) became the popular technique. It had the less postoperative pain and shorter recovery time compared to the conventional technique. With using MIS technique, less cut of quadriceps tendon was the key. It related to keep more quadriceps strength and improve functional performance after TKA. However, there was no previous studies about the effect of quadriceps incision length in the recovery time of the quadriceps strength. The investigators hypothesized that longer quadriceps incision affected the longer recovery time of quadriceps strength in MIS-TKA.
