“Chondromalacia, also known as “runner’s knee,” is a condition where the cartilage on the undersurface of the patella (kneecap) deteriorates and softens. This condition is common among young, athletic individuals, but may also occur in older adults who have arthritis of the knee.

What Are the Symptoms of Chondromalacia?

Chondromalacia will typically present itself with pain in the knee region, known as patellofemoral pain. You may feel sensations of grinding or cracking when bending or extending your knee. Pain may worsen after sitting for a prolonged period of time or during activities that apply extreme pressure to your knees, such as standing for an extended period or exercising.

Treatment Options for Chondromalacia

Physical therapy focusing on strengthening the quadriceps, hamstrings, adductors, and abductors can help improve your muscle strength and balance. Muscle balance will help prevent knee misalignment. Typically recommended are non-weight-bearing exercises, such as swimming or riding a stationary bike. Additionally, isometric exercises that involve tightening and releasing your muscles can help to maintain muscle mass.”
