Article Abstract:
More research is needed to determine whether leeches or any component of their saliva may be effective in treating knee osteoarthritis. A study published in 2004 found that leeches might be effective for this purpose, but the study only lasted for about three months. While leeches were more effective painkillers than diclofenac during the first week, the difference in treatments was not so apparent after three months. In addition, the patients could see which treatment they were receiving and this may have influenced the results.

Article Abstract:
Physical therapy combined with exercise can benefit people with osteoarthritis of the knee. This was the conclusion of a study of 83 patients with osteoarthritis of the knee who received physical therapy plus exercise or low levels of ultrasound stimulation to the knee. Both treatments occurred twice a week for four weeks. Patients who received physical therapy and exercise could walk further, had fewer symptoms and were less likely to need surgery than those who received ultrasound. This effect lasted for up to one year.

Article Abstract:
Leeches or their saliva may be an effective treatment for knee osteoarthritis, according to a study published in 2003. Leeches were used because a substance in their saliva called hirudin decreases inflammation. The patients who used leeches reported less pain, stiffness, and better function than those who used topical diclofenac. However, the patients could see which treatment they received, which could have influenced the results.
