Here is some good info that I pinched from a medical encyclopedia a couple
of years ago. What you do with it, is on your own head (or knee I 'spose).
A degenerative condition of the patellar cartilage usually occuring in
young adults and sometimes following injury, It may be painfull but is
often painless, and can cause intermittent effusions into the knee joints.
The cartilage on the posterior aspect of the patella becomes roughened.
Chondromalacia refers to wear and tear (destruction) of the articular
cartilage without signs of OA. Most usually it affects the patello
femoral joint causing a characteristic clinical entity called
‘patello femoral syndrome’ or ‘patellor chondropathy’. Articular
cartilage of the patella becomes involved in a process that leads to
softening, cracking and wearing away of the surface. This syndrome can
occur at any age but is most frequently seen in teenagers and young adults
and its onset if often insidious.
The basic aetiology of chondromalacia is unknown, but overuse or acute
patellar contusion can often be found in conjunction with the onset of
symptoms. Many predisposing factors have been found, such as abnormal
distal or proximal placement of the patella; excessive patella laxity and
sublaxaction; lower extremity malalignments (ankle hyperpronation,
external tibial torsion, excessive Q-angle, increased femoral anteversion,
leg length inequality); and hypoplastic vastus medialis obliquus of the
quadriceps muscle. These factors may predispose the patella to lateral
displacement particularly when vigorous quadriceps contraction occurs.
Clinically, the patient with chondromalacia presents pain in the front
of the knee. It is characteristically aggrivated by activities such as
running, climbing stairs or kneeling and is relieved by rest. The pain
is made worse by prolonged sitting with the knee bent, such as when
one attends the cinema or theatre. After prolonged sitting,
rectropatellar pain and stiffness on initiating activity is also typical.
Patellar chondromalacia, when present, typically appears in sporting
activity like running and jumping, and very often makes continuation
impossible. At rest, the symptoms are quickly relieved. These overuse
symptoms can be alleviated more permanently by a quadriceps muscle
exercise program, a patellar knee brace and anti-inflammatory medication.
If symptoms are extremely severe and persistent, an abnormal patellofemoral
tracking mechanism (lateral subluxation) can be treated surgically.
Since patellar chondromalacia is often associated with patellar laxity
and subluxation, these patients can have an increased risk of a complete
luxation of the patella during activity. In prevention of complete
luxation, all the above mentioned measures must be performed. If a
complete patellar luxation does occurs, surgery is often needed.
