Chondromalacia (definition)

Softening of articular cartilage beneath the patella

Crepitus

A "crunchy" feeling felt upon palpation, a sign of inflammation

Patellar Tendinitis

An overuse injury that occurs frequently with runners and jumpers

Hamstring Strain

Occurs more frequently during deceleration of a sprint, rather than the acceleration

Myositis Ossificans (definition)

The abnormal growth of bone tissue within a muscle. Frequently occurs in the quads.

Quadriceps contusion

"Deep thigh bruise"

Valgus Stress

A type of stress that can cause injury to the MCL, ACL and meniscus. Also makes someone more likely to experience patellar tendinitis or patellofemoral pain.

Varus Stress

A type of stress that can cause injury to the LCL or meniscus.

Patellar Bursitis (MOI)

Direct blow, fall on bent knee or consistent rubbing

PCL (written MOI)

Fall on bent knee, tibial hitting first

ACL (written MOI)

Planting + twisting, valgus stress, hyperextension

Meniscus (written MOI)

Deep flexion + torsion, excessive knee movement in any direction combined with ligament damage

A disease that results in an abnormally large tibial tuberosity

Patellar Tendinitis

"Jumper's Knee"

Myositis Ossificans

bone growth within the muscle due to improper contusion treatment

Cruciate

A ligamentt INSIDE the knee joint

Collateral

A ligament OUTSIDE the knee joint
