Diagnosis

Signs and symptoms

Knee osteoarthritis

Osteoarthritis of the knees is associated with buckling, or sudden giving way, of the knees.[1] This is more likely if the quadriceps muscle is weak.

A screening survey is positive if any one of the following is answered yes:[1]

  • 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?)

Using the prevalence of disease in this study (5% to 8%), the predictive values are:

Hip osteoarthritis

A screening survey is positive if any one of the following is answered yes:[1]

  • 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?)

Using the prevalence of disease in this study (5% to 8%), the predictive values are:

Treatment

Medications

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.[2] However, acetaminophen at a dose of 4 grams per day can increase liver function tests.[3]

Supplements

Dietary supplements have been studied.

Chondroitin

A meta-analysis of randomized controlled trials found no benefit from chondroitin.[4] This meta-analysis included the GAIT randomized controlled trial of Clegg et al.[5] A longer followup of the GAIT show no benefit from sodium chondroitin on reduction in loss of joint space width.[6]

A more recent trial is positive. A trial sponsored by the manufacturer reports less loss of joint space with chondriotins 4 and 6.[7]

Selected randomized controlled trials of chondroitin

Glucosamine

For more information, see: 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[5][6] is effective for osteoarthritis.

S-adenosylmethionine

For more information, see: S-adenosylmethionine.


Acupuncture

For more information, see: 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]

Injections

Injections of the hip joint for labral tears may not be effective.[11]

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.[12][13]

Prognosis

Knee

The strongest predictors of poor functional outcome are age, body mass index, anxiety and pain severity.[14]

Hip

Among patients presenting with hip pain to their general practitioner, the rates of total hip replacement are:[15]

  • 12% of patients at 3 years
  • 22% after 6 years

Predictors of the need for a total hip replacement are:[15]

  • 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
