A research conducted by the University of Western Ontario and Lawson Health Research Institute has concluded that a knee surgery does not relieve osteoarthritis patients from joint pain and provide for no improvement in knee functioning. A minimally invasive surgical procedure, arthroscopic surgery, adds no therapeutic value to medication and physical therapy for patients suffering from moderate osteoarthritis. The authors of the study have suggested that the resources which are currently allotted to arthroscopy for osteoarthritis could be utilized in a better way if directed elsewhere.
