Abstract
BackgroundThe number of patients receiving total knee arthroplasty (TKA) has been rising every year due to the aging population and the obesity epidemic. Post-operative rehabilitation is important for the outcome of TKA.MethodsA series of 34 patients who underwent primary unilateral TKA was retrospectively collected and divided into either exercise group (n = 16) and control group (n = 18). The exercise group underwent a 24-week course of circuit training beginning 3 months after total knee arthroplasty (TKA). The effect of circuit training on TKA patients in terms of motion analysis, muscle strength testing, Knee injury and Osteoarthritis Outcomes Score (KOOS) questionnaire and patient-reported outcome measurement Short-Form Health Survey (SF-36) at the pre-operation, pre-exercise, mid-exercise, and post-exercise.ResultsMotion analysis revealed the stride length, step velocity, and excursion of active knee range of motion significantly improved in the exercise group when compared to those in the control group. KOOS questionnaire showed a greater improvement in pain, ADL, and total scores in the exercise group. The SF-36 questionnaire revealed a significant improvement in general health, bodily pain, social function, and physical components score in the exercise group.ConclusionsThe post-operative circuit training intervention can facilitate recovery of knee function and decrease the degree of pain in the TKA and might be considered a useful adjunct rehabilitative modality. The ultimate influence of circuit training on TKA needs further a prospective randomized clinical trial study and long-term investigation.Trial registrationNCT02928562
Highlights
The number of patients receiving total knee arthroplasty (TKA) has been rising every year due to the aging population and the obesity epidemic
The demographic data, including age, height, and weight was similar in the exercise and control groups (Table 1)
When comparison was performed within the individual group in temporal fashion, it was shown that stride length, stride velocity, step length, and step velocity increased in mid-excise assessment in the exercise group, while no such difference was noted in control group
Summary
The number of patients receiving total knee arthroplasty (TKA) has been rising every year due to the aging population and the obesity epidemic. The number of patients receiving TKA has been rising every year due to the aging population and the obesity. The retrospective study focused on the female and assessed the feasibility and effect of post-operative circuit training intervention on TKA. The circuit training intervention would carry out at 3 months after the operation for 6 months The assessments of this intervention were measured using motion analysis and muscle strength testing, KOOS questionnaire, and patient-reported outcome measurement Short-Form Health Survey (SF-36). The goal was to demonstrate the effect, if any, that circuit training intervention might have on post-operative knee functional recovery and daily activities
