N E W S L E T T E R WHAT IS RUNNER’S KNEE, AND WHAT CAN I DO ABOUT IT?
Blog by: Vanessa Salguero, PTA
Chondromalacia patella, also know as, “runner’s knee,” is a common injury that we see today, specifically in young females. Chondromalacia patella (CMP) is defined as the softening and deterioration of the cartilage under the patella. CMP occurs due to improper alignment of the patella, which then causes the undersurface of the patella to grate and deteriorate along the femur during movement. Females are more prone to this injury secondary to having wider hips than men. Other individuals who can be predisposed to this common injury are flat-footed people, those who have muscle imbalances between the outer and inner quads, and those with an unusually shaped patellar undersurface. A common symptom that an individual will experience with CMP is discomfort in the inner aspect of the knee. This becomes aggravated by activity such as running, jumping, climbing, descending stairs, and by prolonged sitting. Other symptoms include, a sense of tightness or fullness in the knee (particularly
if the knee becomes swollen) and grinding or crepitus, which can be felt when bending and straightening the knee. One main solution that a physical therapist provides for the patient is coming up with therapeutic activities that restore the balance between the quad muscles and retract the patella to its original location. These activities include strengthening the muscles in the inner aspect of the quads and stretching the muscles of the outer quads. Other key solutions include controlling pain and inflammation, patellar taping, as well as home exercises and protocols. Most importantly, the physical therapist must incorporate patient education so that the patient understands why it is essential to avoid motions or activities that irritate cartilage under the patella, such as severe knee flexion.
