Patellofemoral syndrome (PFS) also known as Runner's Knee due to runners being the ones who experience this the most. The stress from running causes irritation where the kneecap rests on the thighbone. Pain is felt in front of the knee (patella), and can be sudden, sharp and dull. The cause is mostly due to poor development of quadriceps and tight hamstrings. Weak quadriceps would not be able to support the patella , leading to movement of the knee alignment, causing imbalance and inflexible hamstring putting pressure on the knee.
Symptoms of PFS or Runner's Knee:
It is important to see a healthcare provider if you are experiencing any of the symptoms below:
Knee pain when sitting with bent knees ( squatting, jumping, going down stairs.)
Sudden experience of knee buckling
Knee crepitus - certain movements may cause grinding or a crunching sensation within the knee
Stiffness at rest
Knee swelling
Cause of Patello Femoral Syndrome:
Overuse: repetitive stress causing cartilage under kneecap to wear out, roughen or soften
Muscle imbalance or weakness : changes under the kneecap or a kneecap that is not properly aligned
Excessive weight
Surgery - knee surgery to repair ACL using own patellar tendon as a graft, increases risk of patellofemoral pain
Injury: dislocation or fracture
Gender:- women have a higher chance of developing PFS due to different knee alignment and wider hips
Treatment for Runner's Knee
Runner’s knee can get progressively worse if untreated, it is important to treat it via:
Taping or bracing kneecap
Surgery
Physical therapy exercises - increase flexibility and decrease tightness around knee ( ex: straight-leg raises )
Taking nonprescription anti-inflammatory drugs to decrease pain, swelling, stiffness ( ex: ibuprofen or naproxen )
Athletic therapy
Chiropractic rehab
Acupuncture
Prevention for Patello Femoral Syndrome:
Maintain strength - Strong quadriceps and hip abductor muscles to increase balance
Stretch - warm up gently before any physical activity to increase flexibility
Lose weight - Less stress on the knees
Proper shoes - Wearing the correct shoe wear ( orthotics for flat feet ) , good quality and good shock absorption
Proper running form - Run on a soft platform, lean forward and keep knees bent. Walk or run in a zigzag pattern when going down a steep incline
