Osteoarthritis of the knee

Introduction:
Osteoarthritis of the knee affects about 10% of adults aged over 60 years, with risk increased in those with obesity, and joint damage or abnormalities. Progression of disease on x rays is commonplace, but x ray changes don't correlate well with clinical symptoms.
Methods And Outcomes:
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of non-surgical treatments for osteoarthritis of the knee? What are the effects of surgical treatments for osteoarthritis of the knee? We searched: Medline, Embase, The Cochrane Library and other important databases up to October 2006 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
Results:
We found 74 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
Conclusions:
In this systematic review we present information relating to the effectiveness and safety of the following interventions: acupuncture, capsaicin, chondroitin, education to aid self-management, exercise and physiotherapy, glucosamine, insoles, intra-articular corticosteroids, intra-articular hyaluronan, joint bracing, knee replacement, non-steroidal anti-inflammatory drugs (including topical non-steroidal anti-inflammatory drugs), opioid analgesics, osteotomy, simple analgesics, and taping.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
