| Abstrakt: | BACKGROUND: Patients who underwent total knee arthroplasty (TKA) often experience muscle loss due to pain and limited mobility. Nutritional supplementation and rehabilitation may positively affect the decline in muscle function. OBJECTIVE: The purpose of this study is to evaluate whether whey protein intervention, in addition to conventional rehabilitation training, is beneficial in improving muscle function and quality of life in patients after TKA. METHODS: 72 patients who met the criteria were selected for this randomized controlled study. For the experimental group, whey protein was used as a daily supplement for 12 weeks, while the control group was given a placebo, during which both groups received conventional rehabilitation training. Muscle strength and each of the secondary observables needed to be measured and statistically analyzed preoperatively and at 4, 8, and 12 weeks post-intervention. RESULTS: In total, 62 subjects completed the study: 32 in the experimental group and 30 in the control group. Both groups showed significant improvement in muscle strength, VAS, ROM, AKS and leg circumference after 12 weeks of treatment. Compared to the control group, patients in the experimental group showed significant improvement in muscle strength, VAS, ROM, AKS and leg circumference (p = 0.001, p = 0.002, p = 0.001, p = 0.001, p = 0.001, respectively) after 12 weeks of treatment. CONCLUSION: The 12-week intervention of whey protein nutritional supplement showed significant improvement in muscle mass and function among post-TKA patients besides aiding with conventional rehabilitation exercise.
