Background:
This study aimed to compare the effects of Acupotomy Arthroscope and Arthroscopic interventions on gait and symptoms in patients with Knee Osteoarthritis (KOA).
Methods:
In a single-blind, randomized trial, 73 KOA patients were assigned to receive either Acupotomy Arthroscope or Arthroscopic treatment. The primary outcomes measured were pre- and post-intervention gait spatiotemporal and kinematic parameters. Secondary outcomes included the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Knee Society Score (KSS).
Results:
Both groups exhibited significant improvements in gait parameters and reductions in WOMAC scores, with increases in KSS post-intervention (P < 0.01). The Acupotomy Arthroscope group demonstrated better improvements in gait cycle times and knee flexion angles, although it was less effective in enhancing walking speed.
Conclusion:
Both interventions effectively enhanced gait biomechanics and reduced joint symptoms. Acupotomy Arthroscope was more effective in improving short-term clinical symptoms and functional capacity, while Arthroscopic treatment was superior for pain and mobility limitations.
