A randomized controlled trial: Acupotomy Arthroscope vs. arthroscopic intervention in knee OA patients' gait and symptoms.

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.
