Weakness, stiffness, lack of full range of motion, and instability are also concerns that need to be investigated. Because the knee joint is so multifaceted, pain on the inside of the knee can indicate an entirely different condition than pain on the outside of the knee. This is why proper diagnosis is extremely important when treating knee injuries.
Possible Causes for Knee Pain
Athletes who regularly participate in high-impact sports place extreme demands on their knees by twisting, pivoting, and making sudden stops and starts. However, non-athletes sustain the majority of knee injuries, arising from a variety of causes including poor posture, being overweight, arthritis, gout, sprains, strains, IT band issues, and years of normal activity.
The stabilizing ligaments inside the knee are particularly susceptible to damage. For example, a torn or injured ACL (anterior cruciate ligament), MCL (medial collateral ligament), or meniscus is a regular occurrence among those who twist, pivot and turn with regularity. While such stress injuries are a common source of knee pain among younger people, older people tend to suffer from knee injuries and pain related to every day, degenerative wear and tear and from conditions like osteoarthritis, tendonitis, gout, rheumatoid arthritis, and bursitis.
