Chondromalacia patella is often associated with which of the following factors?

Chondromalacia patella refers to the softening and deterioration of the cartilage on the underside of the kneecap (patella), leading to knee pain and dysfunction. It is often associated with various musculoskeletal factors that influence the alignment and stability of the knee joint.

The connection between foot over-pronation and weak gluteus medius muscles is particularly significant. Over-pronation can lead to altered biomechanics of the lower extremity, resulting in misalignment of the knees and altered patellar tracking. The gluteus medius plays a crucial role in stabilizing the pelvis and maintaining proper alignment of the femur. Weakness in this muscle can contribute to excessive hip adduction and internal rotation during activities such as walking or running, which can further exacerbate the maltracking of the patella and increase the risk of developing chondromalacia.

Therefore, the association of foot over-pronation with weak gluteus medius is a key factor in understanding the mechanical stresses that can lead to chondromalacia patella. Proper assessment and interventions focusing on foot mechanics and strengthening the gluteus medius may help in managing and preventing this condition.
