The meniscus is a ring of cartilage located inside of your knee joint. Its main job is to help absorb shock, however, the meniscus can also provide some stability to the knee. Irritation can occur thru knee trauma, or simply "wear and tear" over time.
Patellar (Kneecap) Dysfunction
The patella is the kneecap. It normally glides smoothly in a "C" shaped pattern when bending the knee. Dysfunctions of patellar glide can lead to localized inflammation and pain, and in more extreme circumstances - patellar dislocation.
Knee osteoarthritis is the wearing down of the thin cartilage covering the ends of the knee bones or underneath the kneecap. Often a natural part of the aging process, osteoarthritis tends to effect people over 50 years of age.
Collateral Ligament Injury
The collateral ligaments provide side-to-side static stability to the knee. There are two such ligaments, the Medial Collateral Ligament (MCL) and Lateral Collateral Ligament (LCL.) Injury most commonly occurs from inner or outer blows to the knee, but a fall/twisting of the knee can also effect these structures.
Cruciate Ligament Injuries
You have two cruciate ligaments, the Anterior Cruciate Ligament (ACL) and the Posterior Cruciate Ligament (PCL.) Together they control the back and forth knee motion. ACL injury is by far the most common and typically found in athletes.
The meniscus is a ring of cartilage located inside of your knee joint. Its main job is to help absorb shock, however, the meniscus can also provide some stability to the knee. Acute trauma such as forceful twisting of the knee or falls are common mechanism for tears.
