Minoda Y, Sugama R, Ohta Y, et al. - This study was sought to evaluate the association between the amount of additional bone resection in the distal femur and the increase in the extension joint gap in total knee arthroplasty (TKA). Researchers assessed 50 knees undergoing TKA for varus osteoarthritis. In the distal femur, the amount of additional bone resection was not equal to the increase in the extension joint gap. The findings revealed that additional bone resection of 4 mm in the distal femur only elevated the extension joint gap by a mean of 2 mm.
