Common Causes Of Patellafemoral Pain Syndrome
Patellofemoral Pain Syndrome (PFPS), also known as runner's knee or anterior knee pain, is a common knee condition characterized by pain around or behind the patella (kneecap). It typically occurs due to problems with the alignment of the patella as it moves along the groove at the end of the thigh bone (femur). Here’s an overview of PFPS:
1. Overuse or Repetitive Stress: Activities that involve frequent bending of the knee, such as running, jumping, squatting, or climbing stairs.
2. Muscle Imbalances: Weakness or tightness in the muscles around the knee, particularly the quadriceps (thigh muscles) and hip abductors.
3. Poor Biomechanics: Abnormalities in knee alignment, such as excessive inward movement of the kneecap (patellar maltracking) during movement.
4. Trauma: Direct blow or injury to the kneecap or surrounding structures.
5. Flat Feet or High Arches: Foot abnormalities that affect the alignment and mechanics of the knee joint.
6. Joint Overload: Excessive weight-bearing activities or sudden increases in training intensity.
1. Pain: Dull, aching pain around or behind the kneecap, which may worsen with activities like running, squatting, or sitting for prolonged periods with knees bent.
2. Crepitus: Crackling or grinding sensation when moving the knee joint.
3. Swelling: Mild swelling around the knee joint.
4. Stiffness: Difficulty bending or straightening the knee fully, especially after periods of inactivity.
5. Pain with Activities: Pain may increase with activities that involve bending the knee, such as climbing stairs or kneeling.
