What Is Runner’s Knee?
Runner’s knee is the common name for patellofemoral pain syndrome, or PFPS, a condition involving irritation of the tissue around or behind the kneecap. Despite the name, you do not have to be a runner to develop it. It shows up in cyclists, hikers, gym-goers, and people who spend a lot of time on stairs or sitting with knees bent for long periods.
The pain typically sits at the front of the knee, around or behind the kneecap, and tends to flare with activity that bends the knee under any significant demand. Running, squatting, going up and down stairs, and prolonged sitting with the knees bent are among the most common triggers. Some people notice a dull ache that builds gradually during activity, while others feel a sharper pain that comes on quickly and forces them to stop.
What is actually happening is that the kneecap is not tracking as smoothly as it should through the groove at the end of the femur. When that movement becomes irritated or inefficient, the surrounding tissue can become sensitised and painful. A detailed look at patellofemoral syndrome and what drives kneecap pain helps explain why this condition is more nuanced than it first appears.
It is also worth knowing that the knee does not work in isolation. The hip, foot, and ankle all influence how forces travel through the kneecap during movement. What feels like a straightforward knee problem is sometimes being driven or maintained by something further up or down the chain.
Getting the right picture early matters. A thorough assessment looks at strength, movement patterns, and what specifically provokes your symptoms so we can understand what is driving the irritation and build a plan that addresses it properly.
Why Runner’s Knee Develops
PFPS tends to build gradually rather than appearing after a single incident. Most often the kneecap becomes irritated when it is repeatedly asked to do more than the surrounding muscles can comfortably support.
Common causes include:
Figuring Out What’s Behind the Pain
Because front-of-knee pain can come from several different sources, the assessment starts with a detailed conversation. Where exactly is the pain, what triggers it, does it build during activity or hit you afterward, and how long has it been going on. Those answers shape everything that follows before we even start the physical exam.
From there we look at how the knee is moving and how well the surrounding muscles are supporting it. That means testing strength through the hip and thigh, watching how you move during single leg activities, and checking whether the foot and ankle are contributing to how much pressure builds behind the kneecap. Weakness through the hip is one of the most consistent things we find with PFPS, and keeping the knee strong and resilient over time almost always becomes a central part of the plan.
The foot, ankle, and lower back are looked at as well. Changes in how any of these areas function can quietly shift how forces travel through the knee on every step, which is why treating the knee alone often misses the point.
Rather than chasing the pain itself, the goal is to understand what created the conditions for it. Imaging is not always needed and is typically only considered when something is not adding up clinically or progress has stalled.

Taking the Pressure Off and Building the Strength to Stay There
Treatment starts with understanding what you want to get back to, whether that is logging kilometres again, getting through a hike without that familiar ache behind the kneecap, or just managing a full day on your feet without paying for it afterward.
Because PFPS is almost always tied to how much pressure the kneecap is absorbing relative to what the surrounding muscles can manage, treatment works on several things at once. This typically means reducing irritation at the front of the knee, improving how the hip and thigh are supporting the joint, and gradually reintroducing the activities that have been aggravating things. Understanding what is actually going on at the front of your knee is something we prioritise early because people who understand their condition tend to make better decisions throughout recovery.
The goal is not to stop moving but to find what the knee can currently handle and build from there. Runner’s knee responds well to a progressive return to activity, but the approach needs to match where you are in the process.
Hands-on treatment may help settle sensitivity and improve how the knee and hip move, but the lasting gains come from strengthening the muscles that take pressure off the kneecap and adjusting the training habits that allowed the irritation to develop. Changes to running volume, footwear, and surface choice often make a meaningful difference.
Understanding why your knee hurts, what aggravates it, and how to pace your return to full activity gives you the tools to manage this condition well and keep it from becoming a recurring problem.
Runner’s Knee Care at Our Burlington Clinic
Getting on top of PFPS usually involves working on a few things at once. Depending on what is driving your symptoms, care typically combines hands-on treatment to settle the irritation around the kneecap with a structured program to build the strength and control that keeps it from coming back.
Chiropractic Treatment
When stiffness through the knee joint or hip is changing how the kneecap moves during activity, chiropractic care may help restore motion through the affected area. Active Release Technique and Graston Technique are commonly used to address tightness through the quadriceps and outer thigh that can pull the kneecap off its preferred path and increase pressure behind it.
Massage Therapy
Tension through the quadriceps, hip flexors, and surrounding muscles can keep the kneecap under sustained pressure long after the initial flare has settled. Soft tissue treatment may help reduce that tension and improve how the knee moves, and works well alongside acupuncture for managing pain and sensitivity during the more acute stages.
Physiotherapy
Building strength through the hip and thigh and retraining how the knee absorbs force during running, stairs, and daily activity is usually the most important part of lasting recovery from PFPS. Physiotherapy may include progressive strengthening, movement retraining, orthotics assessment for foot-related contributors, and laser therapy to support tissue healing.
Your Path Back to Running
Recovery depends on how the knee responds as things settle and capacity builds back up. The process adapts as your tolerance for running, stairs, and activity improves over time.
