Abstract: Introduction: Total knee replacement (TKR) is a common surgery for patients with knee degeneration. Poor post-operative knee flexion range could affect the functional level and lead to prolonged hospital stay. Active stretching, passive stretching and proprioceptive neuromuscular facilitation (PNF) are common stretching methods, but there is no consensus on the best stretching method. The objectives of the present study were to compare the immediate and prolonged effectiveness of three different stretching methods on knee flexion range in people after TKR. Methods: Thirty-six patients aged from 57 to 82 (mean: 70.39 +-7.07) years receiving TKR due to osteoarthritis were studied. They were randomly assigned into 3 groups, namely, active-control stretching (Group 1, n=12), passive stretching (Group 2, n=12) and PNF (Group 3, n=12). Starting from mean post-surgical day 10.08 +-2.61, subjects commenced the stretching program according to their respective group assignment. All subjects received 10 minutes of stretching exercise according to their group assignment. The treatment frequency was 5 days per week for 2 weeks. The immediate change in both active (AROM) and passive flexion range (PROM) of the knee after the first treatment session and the pattern of change in these ranges throughout the 2-week study period were compared among the three groups. The knee flexion range was measured with universal goniometer. Results: For the immediate effect, no statistical difference was found in both AROM (p=0.440) and PROM (p=0.577) among the three groups. The largest improvement was shown in Group 2 in both AROM (8.25%) and PROM (6.30%). For the change in knee range throughout the 2 weeks of study, there was no statistical difference among these groups in both AROM (p=0.507) and PROM (p=0.304). The least improvement in rate of change of range was shown in Group 3 in both AROM and PROM. Conclusion: This study did not show any significant difference in the immediate and prolonged effectiveness of the three methods in knee flexion range for patients after TKR.
