Understanding Patellofemoral Pain & Non-Surgical Knee Relief Options
Learn what patellofemoral pain is, why it happens, and how targeted, non-surgical care can help you move with confidence again.
While chiropractic care commonly focuses on improving function in the spine to reduce neck pain and back pain, in many cases achieving a successful outcome is only possible when treatment addresses conditions elsewhere in the body. For example, any painful condition of the knee can alter one’s gait pattern, which can result in abnormal movement in the ankle, pelvis, and lower back, potentially leading to musculoskeletal pain in those areas as well. In this article, we’ll focus on patellofemoral (PF) pain, or pain that arises in the region of the knee cap, as it’s one of the more common knee conditions.
📌 Key Takeaway: Knee pain rarely affects only the knee—changes in how you walk can stress your ankles, hips, and lower back too.
1. What Is Patellofemoral Pain?
Patellofemoral pain is discomfort felt around or behind the kneecap—often described as a dull ache that may worsen with activities like climbing stairs, squatting, running, or sitting for long periods with the knee bent. It is sometimes called “runner’s knee,” but it can affect anyone, not just athletes!
Pain in the front of the knee, especially with bending or straightening
Discomfort when using stairs, squatting, or sitting for a long time
A feeling of “grinding” or “catching” behind the kneecap in some cases
“Understanding how the kneecap moves is the first step toward lasting, non-surgical relief.”
2. The Unique Anatomy Around Your Kneecap
The anatomy in and around the patella is unique in several ways. First, the patella is the largest sesamoid (free-floating) bone of the body. The role of all sesamoid bones is to improve the function of the muscle–tendon unit connecting to the sesamoid bone by optimizing the angle of action.
In effect, it acts like a pulley, which significantly improves the strength and force of the muscle. The quadriceps muscles attach above at the pelvis and below at the upper pole of the patella. The patella then glides in a groove, or track, located in the distal femur (thigh bone), and a tendon then attaches the lower pole of the patella to a bony prominence located just below the knee on the proximal tibia, or upper “shin bone.”
💡 Pro Tip: Think of your kneecap as a small but powerful guide pulley—when it tracks correctly, your knee moves smoothly and efficiently.
3. How the Kneecap Moves When You Bend and Straighten
When we flex and extend our knee, the patella slides up and down in its track as the quadriceps contract and relax. This occurs automatically when walking, running, climbing, and during many daily activities.
Of the four muscles that make up the quadriceps, three (rectus femoris, vastus lateralis, and vastus intermedius) pull the patella up and out when we extend or straighten the knee, and only one (vastus medialis) pulls the kneecap up and inward. To compensate for this disadvantage, the vastus medialis normally fires first during knee extension, which allows for proper patellar tracking and normal function.
Three quadriceps muscles pull the kneecap slightly outward
One key muscle (vastus medialis) helps pull it inward and stabilize it
Timing and strength of these muscles are crucial for healthy knee motion
4. What Research Tells Us About Patellofemoral Pain
A 2018 study published in the Archives of Physical Medicine and Rehabilitation looked at the “neural drive” of the four quadriceps muscles in 56 women with or without PF pain. Subjects were asked to sustain an isometric, or static knee, extension contraction at 10% of their maximum effort for 70 seconds.
Specialized nerve testing tools measured the average firing rates at various time points during muscle contraction. In the non-PF pain subjects, the vastus medialis fired at higher rates compared with the largest muscle (the vastus lateralis) that pulls the patella up and out. This was the opposite case in the women with PF pain, which investigators suspect may cause and/or perpetuate patellofemoral pain.
📌 Key Takeaway: In many people with PF pain, the stabilizing muscle (vastus medialis) is not firing as strongly as it should—targeted rehab can help correct this!
5. A Simple Exercise to Support Better Kneecap Tracking
This finding has led to the recommendation of isolating the vastus medialis with a specific strengthening exercise. This is accomplished by emphasizing the last ten degrees of full knee extension by completely locking or straightening out the knee in extension followed by only a slight bend.
Gently straighten your knee until it is fully extended—do not force through pain.
Hold briefly in this “locked” position, focusing on tightening the muscle just above and to the inside of the kneecap.
Slowly release into a slight bend, then repeat in a controlled manner.
This is repeated 10–20 times with or without weight, depending on the degree of injury, pain, and muscle weakness. Your doctor of chiropractic can help train you in performing this exercise properly, as well as offer other highly effective exercises and treatments for knee pain.
💡 Pro Tip: Quality matters more than quantity—slow, controlled repetitions are far more effective than fast, sloppy movements.
6. How Personalized, Non-Surgical Care Can Help
Patellofemoral pain often responds well to a personalized, non-surgical treatment plan. Chiropractors and other musculoskeletal specialists may combine:
Gentle joint and soft tissue therapies to improve alignment and mobility
Targeted strengthening of the quadriceps, hips, and core for better knee support
Gait and posture retraining to reduce stress on the kneecap during daily activities
Lifestyle and activity modifications that support healing while keeping you moving
📌 Key Takeaway: The most effective plans blend hands-on care, advanced assessment, and customized exercises—designed around your goals and activity level.
7. When to Talk With a Doctor of Chiropractic
If knee pain is limiting your work, exercise, or everyday activities, you do not have to wait for it to “go away on its own.” A doctor of chiropractic can:
Evaluate how your knee, hip, ankle, and lower back are working together
Identify movement patterns that may be aggravating your patellofemoral pain
Design a customized, non-surgical plan that fits your lifestyle and goals
💡 Pro Tip: Early evaluation can help you avoid compensations that may lead to hip, ankle, or low back pain down the road.
8. Moving Forward With Confidence
Patellofemoral pain can be frustrating—but it is often highly treatable with the right approach. By understanding how your kneecap moves, strengthening key muscles, and working with a provider who focuses on personalized, non-surgical solutions, you can take meaningful steps toward more comfortable, confident movement.
If knee pain is affecting your daily life, consider scheduling an evaluation to explore safe, innovative options that support long-term joint health and function.
