Osteoarthritis is the most common form of arthritis. It is "a progressive, degenerative joint disease, the most common form of arthritis, especially in older persons. The disease is thought to result not from the aging process but from biochemical changes and biomechanical stresses affecting articular cartilage. In the foreign literature it is often called osteoarthrosis deformans."[1]
Cause / etiology
Leg-length inequality > 1 cm is associated with osteoarthritis of the knee.[2]
Diagnosis
Signs and symptoms
Knee osteoarthritis
Osteoarthritis of the knees is associated with buckling, or sudden giving way, of the knees.[3] This is more likely if the quadriceps muscle is weak.
A screening survey is positive if any one of the following is answered yes:[3]
- During the last 4 weeks, have you had knee pain on most days?
- During the last 4 weeks, have you had knee pain while climbing down stairs or walking down slopes?
- During the last 4 weeks, have you had swelling in one or both knees?
- Do you have knee OA? (If you do, was the diagnosis made by a rheumatologist or a general practitioner?)
- sensitivity = 87%
- specificity = 92%
Using the prevalence of disease in this study (5% to 8%), the predictive values are:
- positive predictive value = 51%
- negative predictive value = 98%
Hip osteoarthritis
A screening survey is positive if any one of the following is answered yes:[3]
- During the last 4 weeks, have you had hip pain (groin or upper thigh) on most days?
- During the last 4 weeks, have you had hip pain while climbing down stairs or walking down slopes?
- During the last 4 weeks, have you noticed any limitation in the range of motion of one or both hips?
- Do you have hip osteoarthritis? (If you do, was the diagnosis made by a rheumatologist or a general practitioner?)
- sensitivity = 93%
- specificity = 95%
Using the prevalence of disease in this study (5% to 8%), the predictive values are:
- positive predictive value = 56%
- negative predictive value = 99%
Treatment
Analgesic medications
The World Health Organization recognizes a "pain ladder" of increasingly potent analgesics to deal with the pain of osteoarthritis. These may be supplemented with adjuvants.
The Disease-Modifying Anti-Rheumatic Drugs (DMARD) used in rheumatoid arthritis and other autoimmune disorders are not indicated in the essentially mechanical wear involved in osteoarthritis.
Analgesics
Acetaminophen
A randomized controlled trial comparing acetaminophen to ibuprofen in x-ray proven mild to moderate osteoarthritis of the hip or knee found that equal benefit.[4] However, acetaminophen at a dose of 4 grams per day can increase liver function tests.[5]
NSAIDs
Tramadol
Opioids
Adjuvants for pain medications
Dietary supplements
A combination of glucosamine and chondroitin dietary supplements may help moderate to severe osteoarthritis according to the GAIT study while neither supplement seems effective alone.[6] However, longer follow-up of the GAIT study showed the combination group tended to have the most loss of joint space.[7]
Chondroitin
A meta-analysis of randomized controlled trials found no benefit from chondroitin as monotherapy.[8]
Glucosamine
A molecule derived from glucosamine is used by the body to make some of the components of cartilage and synovial fluid.
Neither glucosamine sulfate[9] nor glucosamine hydrochloride[6][7] is effective as monotherapy for osteoarthritis.
S-adenosylmethionine
Acupuncture
Acupuncture is probably not effective according to a meta-analysis that concluded "sham-controlled trials show clinically irrelevant short-term benefits of acupuncture for treating knee osteoarthritis. Waiting list-controlled trials suggest clinically relevant benefits, some of which may be due to placebo or expectation effects."[10]
Intraarticular injections
Intra-articuloar injections of the hip joint for labral tears may not be effective.[11]
Joint lavage
Joint lavage, with or without corticosteroids, does not help.[12]
Knee bracing and shoe prosthesis
Laterally wedged insoles and valgus bracing may benefit some patients with arthritis of the medial knee according to a randomized controlled trial. [13]

Surgery
Arthroscopic surgery for osteoarthritis of the knee is not effective according among patients with moderate or severe disease to two randomized controlled trials. However, a number of patients including those with severe disease of two or more compartments of the knee, were excluded.[14][15]
Prognosis
Knee
The strongest predictors of poor functional outcome are age, body mass index, anxiety and pain severity.[16]
Hip
Among patients presenting with hip pain to their general practitioner, the rates of total hip replacement are:[17]
- 12% of patients at 3 years
- 22% after 6 years
Predictors of the need for a total hip replacement are:[17]
- age >/=60 years, morning stiffness
- pain in the groin/medial thigh
- decreased extension/adduction
- painful internal rotation
- body mass index </=30 kg/m(2)
- Kellgren/Lawrence grade of 2 or higher
