Chondromalacia patellae, also known as runner's knee or patellofemoral pain syndrome, is a medical condition characterized by pain and inflammation in the front of the knee, specifically around the kneecap or patella. It is a common injury among athletes, especially runners, cyclists, and basketball players.
Chondromalacia patellae is caused by the breakdown and softening of the cartilage on the underside of the patella. This can be due to several factors, including:
Overuse or repetitive stress: Activities that involve repetitive bending and straightening of the knee, such as running or jumping, can cause stress on the knee joint and lead to chondromalacia patellae.
Muscle imbalances: Weakness or tightness in the muscles surrounding the knee, including the quadriceps, hamstrings, and hip muscles, can cause uneven pressure on the patella and contribute to chondromalacia patellae.
Trauma: A direct blow or injury to the knee can cause damage to the cartilage and lead to chondromalacia patellae.
Symptoms of chondromalacia patellae may include:
Pain and tenderness in the front of the knee, specifically around the patella
A grinding or popping sensation when bending or straightening the knee
Swelling and inflammation around the knee
Stiffness or limited range of motion in the knee
Treatment for chondromalacia patellae may include:
Rest and activity modification: Avoiding activities that aggravate the knee and allowing time for rest and recovery can help alleviate symptoms.
Physical therapy: Stretching and strengthening exercises, as well as techniques to improve alignment and muscle balance, can help improve knee function and reduce pain.
Pain management: Over-the-counter pain medications, such as acetaminophen or ibuprofen, can help alleviate pain and reduce inflammation.
Bracing or taping: Using a knee brace or taping the knee can provide additional support and help reduce pain.
Surgery: In rare cases, surgery may be necessary to repair or remove damaged cartilage.
