ISAKOS: TKA: Increased time to restore quadriceps strength if incision length is >4cm .
Does the Length of Quadriceps Incision Affect the Recovery of Isokinetic Quadriceps Strength After Minimally Invasive Total Knee Arthroplasty: A Prospective Randomized Clinical Trial
60 patients who underwent unilateral minimally invasive TKA were randomized to receive treatment using an incision length in the quadriceps muscle of either < 2cm, between 2 and 4cm, or > 4cm to determine the effect of incision size on rate of healing and quadriceps strength. Results indicated an increase in time taken to restore preoperative quadriceps strength in patients who had an incision length of > 4cm, compared to the other two groups. However, there was no difference found in operative time, blood loss, or hospital stay between the three groups.
