Runners Knee (PFPS)

Runner’s Knee (Patellofemoral Pain Syndrome)

Anatomy and Biomechanics

Runner’s knee, also known as patellofemoral pain syndrome, refers to pain around the kneecap (patella) where it meets the thigh bone. During movements like running, squatting, or climbing stairs, the patella slides in a groove on the femur.

If the kneecap does not move smoothly due to muscle imbalances, weakness in the hips or quadriceps, or poor movement mechanics, excessive stress can develop in the joint, leading to irritation and pain.

Signs and Symptoms

Common symptoms include:

Pain around or behind the kneecap
Pain when running, squatting, or going downstairs
Knee pain after sitting for long periods
Clicking or grinding sensations in the knee
Increased pain with repetitive knee bending

How Physiotherapy Helps

Physiotherapy focuses on correcting the underlying biomechanical factors contributing to knee pain.

Treatment typically includes:

Strengthening the quadriceps and hip muscles
Improving lower limb alignment and movement patterns
Running or gait analysis
Mobility work for the hips and ankles
Progressive return-to-running programs

Research consistently shows that exercise therapy targeting the hip and knee muscles is the most effective treatment for patellofemoral pain.

What Physiotherapists Look at During a Running Injury Assessment

Running is one of the most popular forms of exercise because it is simple, accessible, and incredibly effective for improving cardiovascular health. However, the repetitive nature of running means the body experiences thousands of loading cycles during a single run, which can lead to overuse injuries when movement patterns, strength, or training load are not optimal. Small asymmetries in mobility, strength and endurance become very apparent with these thousands of steps. When

How Pre-Operative Physiotherapy Improves Surgical Outcomes

Preparing for surgery is about more than just scheduling a procedure and waiting for your operation date. What you do before surgery — especially when it comes to your physical readiness — can profoundly influence how well you function afterward. This is where pre-operative physiotherapy , also called prehabilitation , comes in. A recent research article published in JAMA Network Open looked at randomized clinical trials involving more than 3,500 patients to determine wheth

Hockey Mobility: Why It Matters and the Best Stretches to Improve It

Hockey season is back, and with it comes long practices, fast-paced games, and the physical demands of being back on the ice. After a summer away, many players quickly ramp up their training—which can put extra stress on the body if it isn’t moving properly. That’s why mobility is so important for hockey players. Watch this video to learn about why hockey mobility is so important and for simple static and dynamic stretches that can improve mobility and lower the risk of

The Most Important Muscle in Your Body: Meet the Psoas

By: Nancy Botting Many Therapists believe that the psoas muscle is the most important muscle in the body. The psoas muscle helps to flex the hip in standing, walking, and running, and to flex the spine over the legs in sitting, cycling, canoeing or kayaking. It is a long cylindrical muscle (on average 16" in length) deep within your core and it often also described as the "thickest" muscle of the body. In animals it is the "tenderloin". It is a long and lean muscle due to it'

The Benefits of Physiotherapy for Osteoarthritis

Hello everyone, Hope you are all having a great summer! We wanted to share this link with you to an interesting article from the British Journal of Sports Medicine that speaks to the benefits of starting physiotherapy earlier rather than later, and the relation to future risk of opioid use in people with knee osteoarthritis (OA) . This article is based off of a study conducted with data from a group of adults with mild to moderate knee OA referred for physiotherapy within 1
