Thigh and Knee Circumference, Knee‐Extension Strength, and Functional Performance After Fast‐Track Total Hip Arthroplasty

Abstract: Knee-extension strength is considerably reduced at discharge after THA, but the early strength reduction does not correlate with changes in thigh or knee circumferences. Because functional performance is also considerably reduced at discharge (unrelated to reduced knee-extension strength), other mechanisms such as fear, avoidance of movement, or decreased hip-muscle strength also may be involved.

“…We included only a small number of participants from a single medical center, so our observations must be interpreted with caution. The present study investigated only the early postoperative period; these findings should be considered preliminary for TKA and THA, although other studies have considered physical function in the early period after TKA and THA[12,18,24]. Scores on the preoperative PCS in the present study were higher than those reported in previous TKA studies[9-11].…”

“…The strength-testing position of the knee extensors was confirmed using a goniometer at a hip angle of 90° and knee flexed to 60°. If necessary, the feet were supported by a small bench[18-22]. A strap was attached between the examination couch and a point on the participant’s ankle, 5 cm above the lateral malleolus.…”

“…As muscle weakness also appears to be a problem in the early postoperative period, the reduced quadriceps muscle function amounting to about 60–80% reduction after TKA (Mizner et al 2005, Holm et al 2010) and to about 30–40% after THA (Holm et al 2011), may call for early physiotherapy including strengthening exercises and/or reduction of inhibitory neural reflexes that may contribute to impaired muscle function (Mizner et al 2005). …”
