Understanding Knee Pain
Before we dive into PFPS specifically, it's important to understand knee pain in general. The knee is a complex joint that bears a significant amount of body weight and stress during daily activities and sports. Common types of knee pain include:
- Patellofemoral Pain Syndrome (PFPS)
- Osteoarthritis
- Meniscus tears
- Ligament injuries (ACL, MCL, etc.)
- Tendinitis (e.g., patellar tendinitis or "jumper's knee")
- Bursitis
Each of these conditions requires a specific approach to diagnosis and treatment. In this article, we'll focus on PFPS, one of the most common knee complaints we see in our East Kilbride clinic.
What is Patellofemoral Pain Syndrome?
PFPS is a term used to describe pain around or behind your kneecap (patella). It's often referred to as "runner's knee" or "jumper's knee", but it can affect anyone, regardless of their activity level [1].
Common Symptoms
- Pain at the front of the knee, especially when bending it
- Discomfort when sitting for long periods
- A grinding or clicking sensation in the knee
- Pain that worsens with activity, particularly running, jumping, or climbing stairs
- Difficulty kneeling or squatting
PFPS affects up to 25% of the general population and up to 40% of active individuals [2]. If these symptoms sound familiar, you're not alone, and there are effective ways to manage this condition.
Understanding the Causes
Recent research suggests that PFPS is more complex than simply the kneecap not tracking properly. Factors can include:
- Muscle imbalances or weakness, particularly in the hip and thigh
- Poor movement patterns
- Overuse or sudden increases in training load
- Foot mechanics (like flat feet or high arches)
- Tight muscles or soft tissues around the knee
- Poor core stability
It's important to note that while some people may experience a grinding sensation, this doesn't always indicate a problem. Some level of crepitus (grinding or cracking sounds) can be normal in healthy knees [3].
Traditional Physiotherapy Approach
Traditional physiotherapy for PFPS often focuses on basic, isolated exercises and modalities:
- Quadriceps strengthening exercises (e.g., straight leg raises, quad sets)
- Simple hip strengthening exercises (e.g., clamshells)
- Basic calf exercises (e.g., calf raises)
- Stretching routines for the quadriceps, hamstrings, and calf muscles
- Patellar taping or bracing
- Use of orthotic devices
- Advice on activity modification
While these approaches can provide a starting point, especially for individuals in the early stages of rehabilitation or those with significant deconditioning, research suggests they may not fully address all the factors contributing to PFPS, especially in active individuals or those looking to return to high-level activities [12].
The Outlaw Approach: Sports Therapy and Strength Training
At Outlaw Athlete Therapy, we take a more comprehensive sports therapy approach to managing PFPS, which builds upon basic exercises and incorporates advanced techniques based on current evidence:
- Thorough Assessment: We evaluate not just your knee, but your entire lower body mechanics, including hip strength, ankle mobility, and movement patterns during functional tasks. Research has shown that PFPS is often related to hip and trunk dysfunction, not just local knee factors [13].
- Progressive Strength Training: We go beyond isolated exercises, incorporating heavy, compound movements that target multiple muscle groups. This approach is based on recent research showing the benefits of progressive loading for PFPS [4]. Studies have demonstrated that high-intensity resistance training can be more effective than traditional low-load exercises for PFPS [14].
- Functional Movement Training: Rather than relying solely on basic, single-joint exercises, we focus on improving movement patterns that translate directly to your daily activities or sport, such as squats, lunges, and step-ups. Evidence suggests that functional exercises are more effective than non-weight bearing exercises for PFPS [15].
- Dynamic Load Management: We help you understand how to gradually increase your activity level and exercise intensity without overloading your knee, using principles from sports periodisation. This approach is supported by research on load management in running-related injuries [16].
- Comprehensive Education: We empower you with in-depth knowledge about your condition, pain science, and long-term management strategies. Studies have shown that patient education is a crucial component of effective PFPS management [17].
- Advanced Manual Therapy: When necessary, we use targeted hands-on techniques to address soft tissue restrictions and joint mobility issues that may be contributing to your PFPS. While the evidence for manual therapy in PFPS is mixed, it can be beneficial when combined with exercise therapy [18].
- Sport-Specific Return-to-Activity Planning: We develop a structured plan to safely return you to your desired activity level, incorporating plyometrics, agility drills, and sport-specific exercises as appropriate. This approach is based on research showing the importance of sport-specific training in injury rehabilitation [19].
This evidence-based approach allows us to address the complex nature of PFPS more effectively, providing a pathway not just to pain reduction, but to improved performance and long-term joint health.
The Science Behind Strength Training for PFPS
Recent studies have shown that strength training, particularly focusing on the hip and knee muscles, can significantly reduce pain and improve function in individuals with PFPS [5].
A 2018 study published in the British Journal of Sports Medicine found that hip and knee strengthening was more effective than knee strengthening alone for reducing pain in PFPS [6]. The study used exercises similar to those you might see in a gym setting, including leg press, leg extension, and hip abduction exercises.
Another study from 2015 showed that proximal muscle (hip and core) rehabilitation was effective for PFPS, with both short and long-term benefits [7].
These findings support our approach at Outlaw Athlete Therapy, where we incorporate "bodybuilding" style training into our rehabilitation programmes. However, it's crucial to note that this training is done under professional guidance, with proper form and load management to ensure safety and effectiveness.
Activity-Specific Considerations
Different activities place varying demands on the knee joint. Here are some activity-specific considerations for PFPS:
- Running: Focus on proper running mechanics, gradually increasing mileage, and incorporating strength training.
- Gym Workouts: Emphasise proper form in squats and lunges, and address any mobility limitations.
- Daily Activities: Improve mechanics for tasks like climbing stairs or getting up from a chair.
- Desk Jobs: Address posture and incorporate regular movement breaks.
- Sports: Focus on sport-specific movements and strengthen supporting muscles.
Our sports therapy approach takes these activity-specific demands into account when designing your treatment plan.
Myth Busting
Let's clear up some common misconceptions:
- Myth: Complete rest is the best treatment for PFPS. Truth: While reducing aggravating activities is important, complete rest can lead to deconditioning. Guided, progressive loading is key [8].
- Myth: Running is bad for your knees. Truth: When done properly and progressively, running can actually be beneficial for knee health [9].
- Myth: You always need to tape your knee or use a brace for PFPS. Truth: While these can provide short-term relief, they're not a long-term solution and can create dependency [10].
- Myth: PFPS is always caused by weak quads. Truth: While quad strength is important, research shows that hip weakness is more strongly associated with PFPS [11].
Self-Help Strategies
While professional guidance is often the most effective approach for managing PFPS, here are some evidence-based strategies you can try at home. Keep in mind that these are starting points and may not be sufficient for everyone, especially those with more persistent or severe symptoms:
- Gradual Activity Progression: Avoid sudden increases in training volume or intensity. Research shows that gradual load progression is key in managing and preventing running-related injuries, including PFPS [20].
- Functional Strengthening: Focus on exercises that mimic everyday movements. While isolated exercises like clamshells have traditionally been prescribed, current evidence suggests that functional, weight-bearing exercises may be more effective [21]. Try:
- Squats (starting with bodyweight and progressing as comfortable)
- Step-ups
- Forward and lateral lunges
- Improve Overall Body Awareness: Exercises that enhance proprioception and neuromuscular control can be beneficial. Single-leg balance exercises, for example, have shown promise in improving knee control [22].
- Address the Entire Kinetic Chain: Don't focus solely on the knee. Exercises that target the hips, core, and even the ankles can contribute to better knee health. Planks and bridges are good starting points [23].
- Maintain Cardiovascular Fitness: If running is painful, consider low-impact alternatives like swimming or cycling to maintain fitness while managing your symptoms [24].
- Use Pain as a Guide: Mild discomfort during exercise is generally okay, but sharp or severe pain is a sign to stop. This aligns with current pain science which suggests some pain during rehabilitation can be acceptable [25].
- Footwear Considerations: While the evidence on footwear's direct impact on PFPS is mixed, comfortable shoes that provide adequate support for your foot type may help. If you're a runner, consider having your gait analysed by a professional to ensure your shoes are appropriate [26].
Remember, these strategies are not a substitute for professional assessment and treatment. If your symptoms persist or worsen, it's crucial to seek help from a qualified sports therapist or healthcare professional.
When to Seek Professional Help
While many cases of PFPS can improve with self-management, you should consider seeking professional help if:
- Your pain persists for more than a few weeks despite self-care measures
- The pain is severe or getting worse
- You have difficulty with daily activities
- You notice swelling in your knee
- You feel unstable or like your knee might give way
Remember, while we at Outlaw Athlete Therapy specialise in sports therapy and strength-based approaches, we always recommend consulting with your GP for a proper diagnosis, especially if you have severe or persistent symptoms.
