Patellofemoral pain syndrome
A pathology involving pain in the front part of the knee, often caused by the kneecap (patella) not sitting properly against the thigh bone (femur) and putting too much pressure on the articular surfaces.

The main cause of patellofemoral pain syndrome (PFPS) is the displacement of the patella's path of motion during knee flexion and extension. Normally, the kneecap is kept stable by ligaments and muscles in the thigh. If these structures are not working properly, the kneecap can move out of place. This can cause the surrounding tissues to overstretch, which puts more pressure on the articular surfaces. Over time, repeated small injuries and ongoing inflammation can cause the cartilage in the joint between the kneecap (patella) and the thigh bone (femur) to thin out. This makes the cartilage less elastic, which causes pain and accelerates its deterioration.
Causes
Abnormal knee joint biomechanics.
Valgus (X-shaped) leg curvature.
Thigh muscle weakness or imbalance.
Improper foot position (e.g., flat feet or flat-valgus setting).
Excessive strain on the knees when playing sports.
Prolonged sitting posture.
Frequent joint microtraumas.
Abnormalities such as joint hypermobility.
Symptoms
Anterior knee pain that increases with physical activity.
Discomfort when squatting, going up or down stairs.
Crunching or crepitation in the joint when moving.
Locking or stiffness in the knee.
Patellar swelling or soreness.
Weakness or hypertrophy of the quadriceps femoris muscle.
After-effects
Untreated patellofemoral pain syndrome can cause:
Chondromalacia patellae - damage and thinning of the cartilage covering the articular surfaces.
Chronic pain and impaired mobility.
Degeneration of malposition of the patella and its structures, development of arthrosis.
Лечение

Nonsurgical treatment
Treatment for PFPS in the early stages aims to restore the normal way the knee joint moves, reduce inflammation, and strengthen the quadriceps and calf muscles to improve joint stability. The main treatment methods are physical, massage, manual, and exercise therapies.

Surgical treatment
Surgical intervention may be required if other treatments don't work and there is severe cartilage damage. Advanced procedures include: Arthroscopy: removing damaged cartilage, osteophytes or adjusting the patellar trajectory. Ligament reconstruction: restoring damaged stabilizing structures. Lateral release: releasing the tension of the ligament that deflects the patella. Osteotomy: adjusting limb axis for even load distribution.
