Patellofemoral Pain Syndrome

Patellofemoral pain syndrome, sometimes called runner's knee or anterior knee pain syndrome, describes pain around the joint between the kneecap and thighbone. It often reflects how the knee is being loaded rather than one single structural injury. Patellofemoral pain syndrome causes pain around or behind the kneecap during bending, stairs, squatting or prolonged sitting.

Difficulty Climbing Stairs is a very common presentation of patellofemoral pain syndrome. Knee Pain and Kneecap Pain are also very common presentations. Discomfort may appear after sitting with the knee bent, during squats, running or getting up from a chair.

Some people notice clicking or grinding without serious damage. Giving way, a locked knee, substantial swelling or pain after a major injury suggests another problem may need assessment.

Pain can develop when the kneecap and surrounding tissues are repeatedly loaded during bending. Changes in activity, reduced hip or thigh control, altered foot mechanics and limited recovery may shift stress across the knee. Several contributors can exist together.

Symptoms commonly fluctuate with activity. A sudden return to running, hills or deep squats may provoke a flare, while graded strengthening can improve tolerance. Progress is better judged by daily function and recovery after exercise than by one pain-free session.

Risk factors include a rapid training increase, repetitive stairs or squats, weak hip and thigh muscles, reduced ankle mobility and foot posture changes. Flat Feet may alter how the leg moves and can be one factor among several, rather than a sole explanation.

Diagnosis is based mainly on the pain pattern and a physical examination. The clinician checks kneecap movement, hip and thigh strength, ankle motion, gait and tasks such as a step-down. Imaging is considered if there is trauma, unusual swelling or uncertainty about another condition.

Physiotherapy and Exercise Therapy can build hip, thigh and calf strength while retraining movements that load the kneecap. Gait Retraining may help runners adjust stride or cadence when those changes reduce symptoms.

Custom Orthotics can be considered when foot mechanics contribute to symptoms. Kinesiology Taping may provide short-term movement feedback or comfort for some people, but it works best alongside active rehabilitation.

Break up long sitting, use a gradual activity plan and temporarily shorten painful stairs, hills or deep knee bends. Keep strengthening within an agreed tolerance and monitor whether soreness settles by the following day.

Persistent pain can reduce activity and lead to deconditioning or avoidance of stairs and exercise. Altering the way you walk may then irritate other areas. New swelling, instability or an inability to straighten the knee warrants clinical review.

Build training volume progressively, strengthen the hips and thighs, and maintain ankle mobility. Replace worn footwear when it no longer supports comfortable movement, and vary demanding sessions with recovery or lower-impact exercise.

A physiotherapist or orthopedics clinician can assess the whole movement chain from foot to hip. Describe sitting, stairs, running and squatting triggers so the plan targets your actual activities.
