Abstract
ObjectiveTo investigate the application of proprioceptive neuromuscular facilitation (PNF) combined with isokinetic muscle strength rehabilitation in postoperative rehabilitation of total knee arthroplasty (TKA) for knee osteoarthritis.
MethodsA total of 102 patients with knee osteoarthritis treated in Fuwai Central China Cardiovascular Hospital and Henan Provincial People’s Hospital from January 2018 to June 2020 were selected as the object of study. All patients were treated by TKA, and the patients were divided into observation group and control group by random number table method, with 51 cases in each group. The control group was given PNF for rehabilitation, and the observation group performed isokinetic muscle strength rehabilitation based on the inertvention of the control group. The recovery condition assessed by Knee Western Ontario and McMaster University Osteoarthritis Index (WOMAC), knee flexor and extensor isokinetic muscle strength assessed by peak torque (PT), time to peak torque (TPT), average power (AP) and peak torque/body weight (PT/BW), and knee mobility assessed by Japanese Orthopaedic Association (JOA) knee osteoarthritis score and knee range of motion (ROM), of the two groups were compared and analyzed.
ResultsAfter treatment, the WOMAC scores of the two groups decreased, and the WOMAC scores of the observation group were lower than those of the control group (P<0.05). After treatment, the PT, AP and PT/BW of the flexor and extensor muscles in the two groups were improved, whlie PT, AP and PT/BW of the flexor and extensor muscles in the observation group were higher than those in the control group (P<0.05). After treatment, the TPT of the flexor and extensor muscles in the two groups was decreased, and TPT of the flexor and extensor muscles in the observation group were lower than those in the control group (P<0.05); the JOA score and ROM of the two groups were improved, and the JOA score and ROM of the observation group were significantly higher than those of the control group(P<0.05).
ConclusionsThe application of PNF technique combined with isokinetic muscle strength rehabilitation after TKA for knee osteoarthritis can effectively improve knee joint recovery, improve knee flexion and extensor isokinetic muscle strength, and then optimize knee joint activity.
