Patellofemoral Pain Syndrome (PFPS)

Understanding Patellofemoral Pain Syndrome (PFPS):

Overview:

PFPS refers to pain in the patella (kneecap) and/or femur (thigh bone) areas.

Anatomy:

The kneecap is linked to the quadriceps, a large group of muscles at the front of the thighs, responsible for knee straightening, standing, walking, and various leg movements. The kneecap moves with the quadriceps during knee bending and straightening.

Symptoms:

PFPS pain typically occurs in the front of the knee, near or under the kneecap. It may also manifest deep inside, at the sides, or the back of the knee. The pain often arises without an apparent cause or injury, limiting activities like squatting, kneeling, using stairs, or walking.

Causes:

PFPS is usually influenced by factors such as poor kneecap alignment, muscular imbalance, bony abnormalities, knee joint overuse, tendon overload, and knee trauma. Abnormal kneecap alignment is a common cause, often linked to overactivity and tightness in the outer quadriceps, coupled with weakness in the inner quadriceps. Poor loading of the knee joint may result from glute muscle dysfunction or issues in the foot and ankle.

Treatment:

Effective treatment involves identifying specific PFPS causes and addressing them through manual therapy, strength exercises, functional exercises to restore optimal knee joint function, modalities, and personalized education. The prognosis varies, but consistent therapy and individualized exercises have proven most effective in managing PFPS.
