Chondromalacia patella, also referred to as “runner’s knee,” is a knee condition characterized by the presence of irritated cartilage beneath the kneecap. The term itself translates to “soft cartilage under the kneecap.” Although it commonly affects young athletes, individuals of any age, including older adults with arthritis, can experience this painful condition. The main cause of discomfort is the friction between the femur and the patella.
Risk Factors for Chondromalacia Patella
Chondromalacia patella, a condition characterized by the softening and wearing down of the cartilage on the underside of the kneecap, can be influenced by various risk factors. These include engaging in activities that result in abnormal positioning of the knee cap, as well as having weak or tight muscles around the knee. Additionally, excessive activity or participation in sports that put strain on the knee joints can contribute to the development of this condition.
An imbalance in the muscles located on the outer and inner sides of the thigh, or experiencing trauma to the knee and its surrounding areas, can also pull the kneecap out of alignment. This misalignment further increases the risk of developing chondromalacia patella.
Symptoms of Chondromalacia Patella
Chondromalacia patella is often characterized by several symptoms. One of the most common indications is a grinding sensation experienced when bending the knee. This sensation is typically felt during activities such as knee bends, descending stairs, standing up after prolonged sitting, or running downhill. The associated pain is commonly described as dull or aching and is felt behind, below, or on the sides of the kneecap. Additionally, the pain can become sharper and more intense during the use of the knee.
