Each of the Following Is True About Postoperative Management After

Each of the following is true about postoperative management after primary total knee arthroplasty (TKA) except:

A) Based on the design of the prosthesis,the use of grade III posterior joint gliding techniques may be an appropriate intervention to increase knee flexion after cruciate-excising TKA but not after cruciate-retaining TKA when stretching is permissible.
B) If the TKA involved cementless fixation,weight-bearing recommendations vary widely from weight bearing as tolerated while using a walker or crutches to touch-down weight bearing for 4 to 6 weeks after surgery.
C) Although straight-leg-raising exercises for the operated lower extremity are initiated in supine and prone positions as soon as possible during the early postoperative period,they often are delayed for several weeks in side-lying positions to avoid varus/valgus stresses on the operated knee.
D) Participation in high-impact physical activities should be avoided after TKA,as it may contribute to mechanical loosening of the implanted prosthesis over time.
