Chondromalacia
patellae - Softening of the articular cartilage of the patella
that's produced by osteoarthritis degeneration. Such cartilage is
unsuited for the high compressive loads and frictional forces involved
in squatting, and roughening of the underside of the kneecap is common.
Tight quads are responsible for 80% of chondromalacia cases. Other
causes include aging, repetitive overuse and faulty biomechanics because
of genetics. (The condition may also be called patellar tracking
dysfunction)
Patellaofemoral
Pain Syndrome (PFPS) - Identified by pain in front of the patella,
which intensifies during activity. Also indicated by pain during
extended sitting and/ or walking up stairs. PFPS is considered to be a
tracking problem of the patella, caused by an imbalance between the
medial and lateral quadriceps. The damage to the underside of the
patella isn't unlike uneven tread wear in a car that needs the tired
rotated.
Unstable Knee Joint
- Knee suddenly gives out, often caused by old injuries that have
overstretched the knee ligaments.
Locked Knee -
The usual cause is a torn meniscus or a loose body within the joint
capsule
Swelling /
Tightness - Nearly always indicates an internal injury. See a
physician immediately.
Crepitus -
Noisy knees are no reason for concern, unless accompanied by pain and/
or swelling.
