The Efficacy of High-Intensity Preoperative Physiotherapy Training on Postoperative Outcomes in Greek Patients Undergoing Total Knee Arthroplasty: A Quasi-Experimental Study

Abstract

Purpose: Several studies have shown that patients with severe osteoarthritis (OA) of the knee can reduce their knee pain, improve their quadriceps strength, and improve their functional ability through regular exercise training. The purpose of this study was to investigate the efficacy of a six-week supervised highintensity preoperative training program on muscle strength, functional performance, and patient-reported outcomes in patients undergoing total knee arthroplasty (TKA).Methods: Ninety-eight patients scheduled for unilateral TKA for severe OA were allocated to an intervention group (N = 49) who completed a six-week preoperative training program, five days per week prior to surgery, and a control group (N=49) who did not follow any preoperative training program. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), the Physical Functioning Scale of the Short Form-36 questionnaire (SF-36), Knee Injury and Osteoarthritis Outcome Score (KOOS), quadriceps strength, 20meter walk test, and 30-second chair stand test were assessed at six weeks before surgery (T0), just before surgery (T1), four weeks (T2) and finally 12 weeks (T3) after TKA.Results: Of 98 patients included in our study, 10 individuals withdrew from the study at different stages. Finally, 44 patients were allocated to the intervention group and 44 patients to the control group. When comparing the changes from baseline to the primary test points at T1, T2, and T3, we found a significant group difference in favor of the intervention group for quadriceps strength (<0.001, 0.001, 0.009), 20-meter walk test (<0.001, 0.023, 0.032), 30-second chair stand test (0.001, <0.001, <0.001) and all patient-reported outcomes WOMAC (<0.001, 0.001, 0.007) except from KOOS that showed significant difference only at T1 (<0.001) at T2 (0.048) but not at T3 (0.087).Conclusions: Our study demonstrated that a six-week preoperative physiotherapy training program supervised by a physiotherapist before TKA is efficacious for decreasing knee pain, improving knee function, and enhancing daily living activities.

The Risk Factors and Preventive Strategies of Poor Knee Functions and Osteoarthritis after Anterior Cruciate Ligament Reconstruction: A Narrative Review

“…Prior investigation showed that pre-operative exercises could enhance self-reported knee function, positive outcomes in RTS, and prevent PTOA 93) . Furthermore, pre-operative exercises could minimize lower limb neuromuscular function degradation after surgery 94) . There are two phases of pre-operative treatment of ACLR 95) .…”

Physical therapy as a promising treatment for osteoarthritis: A narrative review

“…Usually, increased physiotheist contact is thought to enhance the rehabilitation of OA patients after knee arthroplasty, especially prolonging postoperative inpatient rehabilitation. For instance, a quasi-experimental study form Dimitrios et al (Vasileiadis et al, 2022) demonstrated that a 6-week physical therapy program supervised by a physiotherapist before surgery is efficacious for decreasing pain, improving knee function, and enhancing living activities. However, recent studies suggested that inpatient or clinic-based rehabilitation offers no clinically important advantages when compared with homebased rehabilitation (Buhagiar et al, 2019).…”
