Knee osteoarthritis is a common degenerative joint condition among the elderly. In the treatment of osteoarthritis of the knee, a combination of thermal therapy and self-management exercise has shown to be effective. The aim of this study was to compare the efficacy of topical heat packs versus focal heat therapy at acupressure points in the treatment of osteoarthritis of the knee.

In 76 patients with osteoarthritis of the knee, a randomized controlled trial was performed. Following inclusion and exclusion criteria, patients were assigned to one of two groups: group 1 (heat pack) or group 2 (cold pack) (Thermal gun). Any of the patients received 30 minutes of medication twice a week for four weeks. They were also given an education curriculum and learned how to do knee exercises at home. Pain severity, muscle strength, knee ROM, WOMAC, and SF-12v2 were all assessed using the visual analog scale (VAS).

Results:
--In the Thermal gun group, function and total scores (WOMAC) and Physical Composite Scale (SF-12v2) were significantly improved after 8 sessions.

--Quadriceps strength was significantly improved after 8 weeks (from 4.42 to 4.63).

--In the Heat pack group, flexion was significantly improved after 8 sessions.

--Mean VAS scores after Heat pack treatment was consistently better (lower) than mean VAS scores after Thermal gun treatment.

Finally, in osteoarthritis of the knee, a combination of focal thermal therapy at acupressure points is a viable conservative treatment. Topical thermal therapy has a synergistic effect when pressure is applied to acupressure points.
