Many patients who come in with “knee pain” are told they have knee osteoarthritis and are sent home with painkillers. But the truth is, knee pain in many young and middle-aged adults has nothing to do with osteoarthritis at all. One of the most common \u2014 and most overlooked \u2014 causes is Patellofemoral Pain Syndrome<\/strong>, or PFPS<\/strong>: pain that arises when the kneecap and the bone surface behind it don’t work together as they should.<\/p>\n\n

What Is PFPS and What Causes It?<\/h2>\n\n

The kneecap (patella) acts like a pulley that helps the thigh muscles work efficiently. In normal movement, it glides smoothly up and down in the groove of the femur. But when something pushes the kneecap off track, the compressive force on the bone surface beneath it builds up until irritation and pain develop.<\/p>\n\n

\"Diagram<\/figure>\n\n

The Main Causes of PFPS Usually Involve Several Factors at Once:<\/h2>\n\n

Imbalanced Thigh Muscles<\/h3>\n\n

Particularly a weak VMO (Vastus Medialis Oblique) on the inner side relative to the outer side, which pulls the kneecap too far toward the outside.<\/p>\n\n

Weak Hip and Glute Muscles<\/h3>\n\n

Multiple studies have shown that weak hip abductors and external rotators cause the leg to collapse inward when weight-bearing, directly increasing the pressure on the kneecap\u00b9.<\/p>\n\n

Tight Calf Muscles and Achilles Tendon<\/h3>\n\n

This makes the ankle and knee absorb more force.<\/p>\n\n

Activity Increased Too Quickly<\/h3>\n\n

For example, starting to run or train hard without building up gradually.<\/p>\n\n

Prolonged Sitting with Bent Knees<\/h3>\n\n

For example, working at a computer or long car rides \u2014 another very common everyday cause.<\/p>\n\n

The typical symptoms are pain around the kneecap or at the front of the knee, worsening when going down stairs, squatting, exercising, or standing up after sitting for a long time. Sometimes the knee makes a noticeable noise when bending.<\/p>\n\n

Treatment: Approaches That Really Work<\/h2>\n\n

PFPS responds very well to treatment, especially when started early and targeted correctly. The main approach has three tiers.<\/p>\n\n

1. Stretching<\/h3>\n\n

Stretching tight muscles reduces the forces that pull the kneecap off track. Muscles that deserve special attention include:<\/p>\n\n

IT Band and the Outer Thigh Muscle (TFL)<\/h4>\n\n

Stand with your legs crossed and lean your body to the side. Hold for 30 seconds, 3 rounds per side.<\/p>\n\n

Front Thigh Muscles (Quadriceps)<\/h4>\n\n

Stand and keep your balance, bend one knee, and pull the ankle toward your buttock. Hold for 30 seconds.<\/p>\n\n

Calf Muscles (Gastrocnemius\/Soleus)<\/h4>\n\n

Stand facing a wall with hands on it, keep the stretching leg extended behind you, bend the front knee, and keep the back heel pressed to the floor. Hold for 30 seconds.<\/p>\n\n

We recommend stretching at least twice a day, without pushing to the point of unbearable pain.<\/p>\n\n

2. Strengthening Exercises at Home<\/h3>\n\n

A research review in the British Journal of Sports Medicine found that strengthening the hip muscles together with the thigh muscles reduces pain better than exercising the thigh alone\u00b2. Recommended exercises to do at home:<\/p>\n\n

Straight Leg Raise<\/h4>\n\n

Lie on your back with one knee bent. Lift the straight leg to about 45 degrees and hold for 5 seconds. Do 15 repetitions, 3 sets.<\/p>\n\n

Clamshell<\/h4>\n\n

Lie on your side with your hips and knees slightly bent. Lift the top knee without rolling your hips. Do 15 repetitions, 3 sets. This strengthens the outer hip muscles.<\/p>\n\n

Mini Squat<\/h4>\n\n

Stand with your feet shoulder-width apart and bend your knees slightly, no more than 30 degrees, keeping your knees behind your toes. Do 15 repetitions, 3 sets.<\/p>\n\n

Important: if the exercises make the pain worse, stop and consult a doctor first.<\/p>\n\n

3. Treatment with Medical Technology<\/h3>\n\n

When symptoms don’t respond well enough to exercise, or the pain is too severe to exercise, treatment with specialized equipment gives good, evidence-based results.<\/p>\n\n

High Intensity Laser Therapy (HILT)<\/h4>\n\n

A high-power laser delivers light energy deep into the tissue, stimulating repair at the cellular level, reducing inflammation, and relieving pain directly. Research published in Lasers in Medical Science showed that HILT significantly reduced knee pain and improved movement function in patients with knee problems\u00b3.<\/p>\n\n

Focused Shockwave Therapy<\/a><\/h4>\n\n

Focused shockwaves deliver energy directly to inflamed or fibrotic tissue, stimulating blood flow and new tissue formation. A review published in the Journal of Orthopaedic Surgery and Research found that shockwave therapy is effective in reducing patellofemoral pain and pain in the tissues around the knee, particularly when there is accompanying tendon inflammation\u2074.<\/p>\n\n

Both of these approaches work best when combined with a muscle-strengthening program \u2014 not as a substitute for it.<\/p>\n\n

Don’t let “knee pain” become the new normal in your life. Untreated PFPS tends to become chronic, and over time the cartilage behind the kneecap can start to genuinely wear down. That’s why early diagnosis and treatment matter far more than waiting for symptoms to worsen. At Freesia Rehab Clinic, our rehabilitation physicians will assess the true cause of your knee pain and design a comprehensive treatment plan covering rehabilitation exercise and treatment with our high-power laser program or focused shockwave program as appropriate. Because a knee that truly stops hurting doesn’t start with painkillers \u2014 it starts with knowing exactly where the problem is.<\/p>\n\n
