Osteoarthritis happens when joints and joint tissues wear down over time.
Usually, doctors use X-ray imaging to see this joint damage. But another
imaging technique may give doctors a better picture.
Magnetic resonance imaging (MRI) spotted many signs of knee osteoarthritis
in patients that had no signs of knee osteoarthritis in X-ray images.

Conservative treatment for cartilage defects in the shoulder, as for any
joint, includes physical therapy, anti-inflammatory medications, and
steroid injections. If these treatments are ineffective, arthroscopy, which
involves removing scar tissue and loose pieces of cartilage through a small
incision, has traditionally been the alternative of choice. But arthroscopy
often provides only temporary relief, since the underlying damage to the
cartilage is not corrected.

A standard shoulder replacement, a decades old treatment for severe
shoulder arthritis, would likely not have worked for her due to her
deficient rotator cuff. However, a recently developed â€“ and radically
different â€“ prosthesis, called a reverse total shoulder, offered the best
chance of decreasing her pain and improving shoulder function.
â€˜A normal shoulder is a ball-and-saucer joint, with its stability and
motion governed to a large extent by the surrounding rotator cuff
musculature,â€™ said Dr Omer Ilhai, an orthopedic surgeon at The Methodist
Hospital in Houston. â€˜In arthritis, the smooth cartilage overlying and
cushioning the surface of the bones is worn away, leaving rough, exposed
bone surfaces to rub against each other. This bone-on-bone contact is very
painful and usually associated with joint stiffness.â€™

Summer is a peak season for many sports and with that comes sport-related
injuries. Among those injuries is shoulder joint dislocation. According to
a literature review in the August 2012 issue of the Journal of the
American Academy of Orthopedic Surgeons, most incidents of shoulder joint
instability are the result of traumatic contact injuries like force or
falling on an outstretched arm; a direct blow to the shoulder area;
forceful throwing, lifting or hitting; or contact with another player.
