    AbstractThe aim of this was to investigate the efficacy of physical exercise (leg swing and quadriceps strengthening exercises) versus platelet-rich plasma (PRP) and hyaluronic acid (HA) combination therapy. From January 2020 to August 2021, 106 patients with Kellgren-Lawrence Grade I-III knee osteoarthritis were divided into leg swing and quadriceps strengthening exercises (Group A) and intra-articular combination injections of PRP and HA (Group B) according to the treatment strategies. Patients in Group A received regular leg swing and quadriceps strengthening exercises for 3 months. Patients in Group B received 2 intra-articular combination injections of PRP (2 mL) and HA (2 mL) every 2 weeks. The primary outcome measures were the Visual Analogue Scale (VAS) and the Western Ontario and McMaster Universities (WOMAC) score. Secondary outcomes included single leg stance test and functional activity by 2-minute walk test and time up and go test. All outcomes were evaluated at baseline and again 1, 3, 6, and 12 months. The VAS and WOMAC scores were similar in both groups at 1 and 3 months after treatment (P > .05); however, Group A patients had significantly superior VAS and WOMAC scores than Group B patients at 6 and 12 months after treatment. For the single leg stance test, 2-minute walk test, and time up and go test, Group A patients were significantly superior to Group B throughout follow-up (P < .001). The leg swing and quadriceps strengthening exercises resulted in a significantly better clinical outcomes than the combined PRP and HA therapy, with a sustained lower pain score and improved quality of life, balance ability, and functional activity within 12 months.Copyright © 2023 the Author(s).
