Exercises to Avoid with Osteoarthritis of the Knee or Hip

Participation in sport is associated with a with a 20—40% reduction in all-cause mortality compared with non-participation. Exercise might also be considered as a fifth vital sign, according to the Lancet: http://goo.gl/gyxYf

Exercises to Avoid with Osteoarthritis of the Knee or Hip include:

- Running and jogging. The difference between how much force goes through your joints jogging or running, as opposed to with walking, is sometimes more than 10-fold your whole body weight
- Jumping rope
- High-impact aerobics
- Any activity where, at any time, you have both feet off the ground at once, however briefly (basketball, jumping)

Fortunately, that leaves a lot of activities that are OK for people with knee and hip osteoarthritis and that can help keep you mobile - see the list at WebMD.

Osteoarthritis at the base of the thumb has a 15-30% prevalence in adults

What is it?

Patients with osteoarthritis of the thumb carpometacarpal joint, or base of the thumb, commonly seek help for their symptoms. Arthritis at the base of the thumb causes functional disability and pain, particularly with “pinching” actions.

How common is osteoarthritis of the thumb?

The prevalence of this condition increases with age and is greatest in postmenopausal women. It ranges between 15% prevalence in adults in Finland and a 33% prevalence in postmenopausal women. This is likely to increase as populations age and people stay active for longer.

How to diagnose it?

Pain reproduced on the axial grind test localizes pathology to the base of the thumb.

Trapeziometacarpal and scaphotrapeziotrapezoid joints should be assessed with plain radiographs (X-rays) that typically show degenerative changes. However, X-rays may underestimate the extent of the disease.

What to do?

Non-operative treatments can ameliorate symptoms and delay surgery in most patients with osteoarthritis of the thumb:

- behaviour modification
- pain relief
- splinting
- corticosteroid injections

No single operative procedure has been shown to be superior:

- simple trapeziectomy has the lowest complication rate
- arthrodesis may be the best option for patients who value pain relief and reliable strength and stability more than mobility (such as younger manual workers)

Symptomatic knee osteoarthritis (OA) increased during the past 20 years but radiographic OA did not

A recent surge in knee replacements is assumed to be due to aging and increased obesity of the U.S. population.

This cross-sectional study used data from 6 NHANES (National Health and Nutrition Examination Survey) surveys between 1971 and 2004 and from 3 examination periods in the FOA (Framingham Osteoarthritis) Study between 1983 through 2005 of the U.S. population.

Prevalence of knee pain increased by 65% in NHANES from 1974 to 1994.

In the FOA Study, prevalence of knee pain and symptomatic knee osteoarthritis doubled in women and tripled in men over 20 years.

However, no such trend was observed in the prevalence of radiographic knee osteoarthritis.

Prevalence of knee pain has increased substantially over 20 years. Obesity accounted for only part of this increase.

Symptomatic knee osteoarthritis increased but radiographic knee osteoarthritis did not. Why the patients are more symptomatic now than 20 years ago?

What is Boomeritis?

In 2006, the NYTimes described the health problems of aging baby boomers who continue to exercise: osteoarthritis which needs "knee and hip replacements, surgery for cartilage and ligament damage, and treatment for tendinitis, arthritis, bursitis and stress fractures." Some doctors call this phenomenon "boomeritis" or "Generation Ouch."

Exercises you may need to avoid if you have moderate or severe osteoarthritis of the knee or hip include:
