Runner's Knee (Patellofemoral Pain): Causes, Prevention & When to Consider Advanced Treatment

Running is one of the most accessible and rewarding forms of exercise – great for fitness, mental health, and overall wellbeing. But for many runners, that sense of freedom can come to a painful halt when runner’s knee, or patellofemoral pain syndrome (PFPS), starts to take hold.

Characterised by pain around or behind the kneecap, this common overuse injury doesn’t just affect marathon runners, it can impact anyone who walks, cycles, or exercises regularly. Understanding what causes it, how to prevent it, and when to seek specialist treatment can help keep you moving pain-free.

What Is Runner’s Knee?

Runner’s knee refers to pain at the front of the knee, usually where the kneecap (patella) meets the thigh bone (femur). It’s caused by irritation in this joint, often the result of misalignment, overuse, or muscle imbalance that alters how the kneecap tracks when you move.

The pain is typically felt:

When going up or down stairs
After sitting for long periods (“movie-goer’s knee”)
During squats, lunges, or runs
Around or behind the kneecap

It can range from a dull ache to a sharp, persistent pain that limits activity.

Common Causes of Runner’s Knee

While the name suggests running is to blame, PFPS can result from a combination of factors, many of which are mechanical or postural:

1. Overuse or Sudden Load Increase

Rapidly increasing mileage, intensity, or hill training can overload the joint before the muscles and ligaments are ready to support it.

2. Muscle Imbalance or Weakness

Weak quadriceps, glutes, or hip stabilisers can cause poor kneecap tracking and increased joint stress. Tight hamstrings or calves can worsen the imbalance.

3. Foot and Gait Issues

Flat feet, overpronation, or worn-out footwear can alter how force travels through the knee during movement.

4. Poor Alignment or Pelvic Mechanics

Even subtle misalignments in the hips, pelvis, or spine (something chiropractors frequently assess) can contribute to uneven pressure on the knees.

5. Previous Injury or Scar Tissue

Past trauma, surgery, or repetitive strain can leave the knee vulnerable to irritation and inflammation.

How a Chiropractor Can Help

For many runners, the key to lasting recovery isn’t just managing symptoms, it’s addressing the root cause of imbalance.

A chiropractor trained in musculoskeletal care can:

Assess your gait, posture, and pelvic alignment to identify mechanical causes.
Provide gentle joint adjustments to restore balance and mobility.
Recommend rehabilitative exercises to strengthen the hips, quads, and core.
Offer soft tissue therapy to release tension and improve muscle function.
Advise on footwear, running form, and training progression.

This whole-body approach helps correct underlying dysfunctions that might otherwise cause the problem to return, not just in the knee, but in other joints too.

When Conservative Care Isn’t Enough

Most cases of runner’s knee respond well to rest, targeted exercises, and chiropractic or physiotherapy care. However, some people experience ongoing pain that doesn’t resolve even after consistent rehabilitation.

That’s when it may be time to consider advanced treatment options:

1. Corticosteroid Injections

For acute inflammation or persistent pain, a precisely guided corticosteroid injection can offer rapid relief, allowing patients to return to rehab and strengthen the joint effectively.

2. Hyaluronic Acid (Lubricating) Injections

For those with wear-and-tear or early joint degeneration, hyaluronic acid injections can restore cushioning and fluid balance, helping the knee move more comfortably and efficiently.

3. NStride® APS (Autologous Protein Solution)

A regenerative treatment derived from your own blood, NStride® delivers anti-inflammatory proteins and growth factors directly to the knee joint.
It’s ideal for runners with chronic irritation or early osteoarthritis who want to avoid surgery and promote long-term joint health.

4. Prolozone Therapy

This oxygen-based regenerative injection helps repair tissue damage, reduce inflammation, and stimulate healing in tendons and ligaments. Prolozone Therapy iis deal for overuse injuries like PFPS.

5. Arthrosamid® for Degenerative Knee Pain

For those with longer-term patellofemoral wear, Arthrosamid®, an innovative hydrogel injection, cushions the joint and provides lasting pain relief.

Preventing Runner’s Knee

Whether you’re recovering or starting fresh, prevention is key to staying injury-free:

Strengthen your hips and quads – focus on lateral glute exercises and controlled squats.
Warm up and cool down properly – dynamic stretching prepares the joints for load.
Rotate footwear and ensure proper fit for your gait.
Increase mileage gradually – avoid sudden spikes in intensity.
Listen to your body – pain is feedback, not failure.

Runner’s knee doesn’t have to end your training or limit your movement. With the right blend of manual therapy, functional strengthening, and advanced medical treatment, most patients make a full recovery, often returning stronger than before.
