Osteoarthritis: Diagnosis and Treatment


Osteoarthritis is a common degenerative disorder of the articular cartilage associated with hypertrophie bone changes. Risk factors include genetics, female sex, past trauma, advancing age, and obesity. The diagnosis is based on a history of joint pain worsened by movement, which can lead to disability in activities of daily living. Plain radiography may help in the diagnosis, but laboratory testing usually does not. Pharmacologic treatment should begin with acetaminophen and step up to nonsteroidal anti-inflammatory drugs. Exercise is a useful adjunct to treatment and has been shown to reduce pain and disability. The supplements glucosamine and chondroitin can be used for moderate to severe osteoarthritis when taken in combination. Corticosteroid injections provide inexpensive, short-term (four to eight weeks) relief of osteoarthritic flare-ups of the knee, whereas hyaluronic acid injections are more expensive but can maintain symptom improvement for longer periods. Total joint replacement of the hip, knee, or shoulder is recommended for patients with chronic pain and disability despite maximal medical therapy


Signs and Symptoms of Osteoarthritis

    Hand
    Pain on range of motion
    Hypertrophic changes at distal and proximal interphalangeal joints (Heberden nodes and Bouchard nodes; Figure 1)
    Tenderness over metacarpophalangeal joint of thumb 
    Shoulder
    Pain on range of motion
    Limitation of range of motion, especially external rotation
    Crepitus on range of motion
    Knee
    Pain on range of motion
    Joint effusion
    Crepitus on range of motion
    Presence of popliteal cyst (Baker cyst)
    Lateral instability
    Valgus or varus deformity
    Hip
    Pain on range of motion
    Pain in buttock
    Limitation of range of motion, especially internal rotation
    Foot
    Pain on ambulation, especially at first metatarsophalangeal joint
    Limited range of motion of first metatarsophalangeal joint, hallux rigidus
    Hallux valgus deformity
    Spine
    Pain on range of motion
    Limitation of range of motion
    Lower extremity sensory loss, reflex loss, motor weakness caused by nerve root impingement
    Pseudoclaudication caused by spinal stenosis


SORT: KEY RECOMMENDATIONS FOR PRACTICE
Clinical recommendationEvidence ratingReferences
Physical therapy using land-based or water-based exercise can help reduce pain and improve function in patients with osteoarthritisB[10] [11] ,[12]
Acetaminophen should be used as first-line therapy for mild osteoarthritis.A16
Nonsteroidal anti-inflammatory drugs are superior to acetaminophen for treating moderate to severe osteoarthritisA16
Intra-articular corticosteroid injections can be beneficial for short-term (i.e., less than eight weeks) relief of osteoarthritis pain of the knee.A[21] [22]
Compared with intra-articular corticosteroids, intra-articular hyaluronic acid njections of the knee are less effective in the short term, equivalent in the ntermediate term (i.e., four to eight weeks), and superior in the long termB[26] [27]
The combination of glucosamine and chondroitin may decrease pain in patients with moderate to severe knee osteoarthritis, although the evidence for this effect is limited and inconsistent.B30
Patients who have continued pain and disability from osteoarthritis of the hip, knee, or shoulder despite maximal medical therapy are candidates for total joint replacement.


Complementary and Alternative Medicine

A meta-analysis on the effectiveness of acupuncture for osteoarthritis of the knee found only short-term benefit, which the authors described as clinically irrelevant.[28] Acupuncture can be of benefit in chronic low back pain, but studies do not differentiate the etiology of the back pain.[29]

The most widely used supplements for osteoarthritis are glucosamine and chondroitin. The literature consisted of small clinical trials until the release of the Glucosamine/Chondroitin Arthritis Intervention Trial (GAIT), which included more than 1,500 patients. The trial had five arms comparing glucosamine alone, chondroitin alone, a combination of glucosamine and chondroitin, celecoxib, and placebo. The results were favorable only for the combination of glucosamine and chondroitin, which appeared to be effective for moderate to severe osteoarthritis of the knee.[30] Chondroitin alone did not show benefit for osteoarthritis of the knee or hip in a meta-analysis.[31]

Balneotherapy is a heterogeneous group of treatments also known as spa therapy or mineral baths. A Cochrane review concluded that mineral baths were of some benefit to patients with osteoarthritis, but the authors addressed methodologic flaws in the studies and urged caution in interpreting the findings.[32] Capsaicin cream is a topical analgesic derived from chili peppers. It has been found to be superior to placebo in treating osteoarthritis pain. It is widely available, is relatively inexpensive, and can be used as an adjunct to standard osteoarthritis treatments.[33] There also is evidence supporting the use of the supplement S-adenosylmethionine (SAM-e) to reduce functional limitation, but not compared with placebo in patients with osteoarthritis pain. The effectiveness of SAM-e is comparable to that of NSAIDs in some studies but with fewer adverse effects.[34]
Surgical

Surgery should be reserved for patients whose symptoms have not responded to other treatments. The well-accepted indication for surgery is continued pain and disability despite conservative treatment. The most effective surgical intervention is total joint replacement, with excellent patient outcomes following total joint replacement of the hip, knee, and shoulder. [1] [35] Many different prosthetic devices are available; however, controlled trials comparing the various devices are lacking. Patients can expect that most current joint prostheses will function well for 15 to 20 years.[35]

There are other surgical approaches to osteoarthritis treatment, but they have not equaled the success of total joint replacement. Randomized trials of arthroscopic debridement for osteoarthritis of the knee have consistently failed to show an advantage over maximal medical therapy combined with physical therapy.[36]

IBS

Diagnostic Criteria for IBS

Abdominal discomfort or pain, for at least 12 weeks (which need not be consecutive) in the preceding 12 months, with two of the following features:

Relief with defecation

Onset associated with a change in stool frequency

Onset associated with a change in form or appearance of stool

These additional symptoms cumulatively support the diagnosis of IBS:

Abnormal stool frequency (more than three times per day or less than three times per week)
Abnormal stool form (loose and watery or lumpy and hard)
Abnormal stool passage (urgency, frequency, feeling of incomplete evacuation)
Passage of mucus (white material)
Bloating or sensation of abdominal distention
