In a meta-analysis of three RCTs of thermotherapy for people with knee OA, 179 patients with physiciandiagnosed
disease (some with X-ray confirmation) received cold or ice packs with or without ice massage, hot packs, or no treatment.24 All subjects took medications as prescribed. The primary outcomes examined were pain relief, decreased swelling, improved range of motion, and better function. One of the studies found that, compared with no treatment, 20 minutes of ice massage five days a week for three weeks had a clinically important benefit for quadriceps strength
(29% relative difference) and produced small gains in knee range of motion (8% relative difference) and
functional status (11% relative difference).The studies were not of high quality and the therapy was administered
for varying amounts of time, but in all three studies improvements were found in range of motion, function, and knee muscle strength. Cold appeared to reduce swelling but not pain. More rigorous research is needed
