Can You Overcome Runner's Knee and Get Back to Running Pain-Free
Runner’s Knee,” or patellofemoral pain syndrome, is more than an inconvenience—it’s a prevalent and complex condition that can derail your running plans. Yet, despite how often it affects runners, many misconceptions surround its causes and treatments.
Could conquering Runner’s Knee be as straightforward as tweaking your training or adding a few exercises to your routine? Perhaps for some, a simple exercise and targeted treatment does the trick. But for others, the path to recovery isn’t quite so clear. Why do some runners bounce back quickly while others struggle for months?
What is Runner's Knee?
Runner’s Knee, clinically known as patellofemoral pain syndrome (PFPS), is not a single injury but a term used to describe pain around the patella or kneecap. It typically arises from the excessive stress placed on the knee joint, particularly where the patella rests against the thighbone.
The pain is often felt during activities that involve bending the knee — such as running, squatting, and climbing stairs — and can be exacerbated by prolonged sitting with bent knees.
The knee is a complex hinge joint stabilised by muscles, tendons, and ligaments. Here’s how it is formed and what typically goes wrong in cases of Runner’s Knee:
Patella and Femoral Groove: The patella, or kneecap, is a small bone located in front of the knee joint. It slides up and down a groove on the femur (thighbone) when the knee bends and straightens. This groove is called the trochlear groove. For the patella to move smoothly, it must be well-aligned within this groove.
Quadriceps and Hamstrings: Imbalances or weakness in these thigh muscles can pull the patella out of alignment during movement, causing it to track incorrectly in the trochlear groove.
Hip and Ankle Factors: Dysfunction in the hip or ankle can lead to altered biomechanics, which can impact the knee. Poor alignment or stability in either of these joints can contribute to knee pain by affecting how forces are distributed through the knee during movement.
Foot Mechanics: The way the foot strikes the ground influences the forces transmitted up to the knee. Overpronation or supination can lead to increased stress on the knee joint, exacerbating conditions like Runner’s Knee.
Symptoms of Runner's Knee
Runner’s Knee can manifest through a variety of symptoms that typically worsen with activity. Understanding these symptoms can help runners and clinicians alike identify the issue early and implement effective management strategies.
Here are the key symptoms associated with patellofemoral pain syndrome:
Pain around or behind the kneecap: The most common symptom of Runner’s Knee is pain around the patella, particularly felt when engaging in activities that put pressure on the knee joint, such as running, squatting, and climbing stairs.
Pain after prolonged sitting: Known as the “cinema sign,” this symptom involves pain that sets in after sitting for long periods with bent knees. It’s a result of pressure building up around the kneecap.
A sensation of grinding or popping: Some people may experience a grinding or popping sensation in the knee during movement. This can be due to the misalignment of the patella as it moves within the trochlea groove.
Swelling: Swelling around the knee may occur, although it’s less common compared to other knee injuries.
Difficulty performing full knee bends: Pain and discomfort can hinder the ability to perform full knee bends, affecting daily activities that require deep knee flexion.
Causes of Runner's Knee
While the condition may seem straightforward, a variety of factors can contribute to its development. Here’s a breakdown:
Overuse and Misuse: Repetitive strain from overuse, particularly in sports or activities that involve a lot of jumping, running, or squatting, can lead to Runner’s Knee.
Equipment and Environmental Factors: Incorrect or worn-out footwear can fail to provide necessary support or cushioning, leading to increased impact and stress on the knees during activity. Running on hard or uneven surfaces can also contribute to the likelihood of developing this condition.
Muscle Imbalances and Weakness: Weak or imbalanced muscles around the knee and hip can fail to properly stabilise and protect the patellofemoral joint. Specifically, weakness in the quadriceps, hamstrings, and hip abductors is often associated with Runner’s Knee
Biomechanical Issues: The way your body moves has a significant impact on the stress experienced by your knees. Specific biomechanical factors often implicated in Runner’s Knee include:
- TT/TG Angle: This measurement assesses the lateral (sideways) position of the tibial tubercle (a bony point below the kneecap) relative to the trochlear groove (the path in the femur where the kneecap moves). An abnormal TT/TG angle can cause the patella to track improperly, leading to increased stress on the patellofemoral joint.
- Patella Alta: This is a condition where the kneecap is positioned higher than usual, which can affect how it engages with the femoral groove. Patella Alta can disrupt normal patellar tracking and increase the risk of dislocation or subluxation, contributing to the development of Runner’s Knee
Treatment Options
Tailored Management Strategies for Runner’s Knee
Effective treatment of Runner’s Knee requires a personalised approach, based on the specific clinical findings of each case. It’s not a one-size-fits-all scenario; rather, treatments are designed to strengthen the right areas and address the unique aspects of each individual’s condition.
Here are the primary treatment options:
- Activity Modification: Initially, it’s crucial to reduce or modify activities that aggravate the knee pain. This doesn’t mean stopping all physical activity but adapting your exercise routine to lessen the impact on your knee.
- Ice Application: Regularly applying ice to the affected area can help manage inflammation and alleviate pain, particularly following activities known to exacerbate symptoms.
- Orthotics and Appropriate Footwear: Utilising orthotics can provide the necessary support to correct foot biomechanics that contribute to knee stress. Coupled with choosing the right shoes based on your foot type, this approach helps minimise undue pressure on the knee.
- Manual Therapy: Targeted manual therapy on the knee and hip musculature can enhance movement quality and relieve pain. Techniques may include massage, mobilisation, and other hands-on treatments to improve joint function and soft tissue health.
- Targeted Strength Training: Strengthening exercises are essential, particularly for the quadriceps, hamstrings, and hip musculature. These exercises help stabilise the knee, improve alignment, and reduce the burden on the patellofemoral joint.
- Considerations for Surgical Intervention
In cases where biomechanical issues such as Patella Alta or an abnormal TT/TG angle contribute significantly to Runner’s Knee, and conservative treatments fail to provide relief, surgical options may be explored. Surgery can realign the patella or correct structural abnormalities to provide long-term relief and functionality. This option is typically considered when all non-invasive treatment approaches have been exhausted.
Overcoming Runners Knee
Runner’s Knee is a common challenge faced by many athletes, from casual weekend joggers to seasoned marathoners. Despite its prevalence, the good news is that with the right approach, overcoming this condition is entirely possible. Each year, we successfully help numerous runners not only manage but completely resolve their Runner’s Knee, enabling them to return to the activities they love without pain.
