Why Do My Knees Hurt When Bending or Squatting?

Overview of Why Do My Knees Hurt When Bending or Squatting?

Experiencing sharp knee pain when bending or climbing stairs? Learn about patellofemoral tracking, cartilage wear, and physical therapy recovery guides.

The knee joint relies on the patella sliding smoothly inside the trochlear groove of the femur. Any muscle imbalance (such as tight outer thighs or weak inner quadriceps) pulls the patella off-track, causing pain.

Common Causes & Pathophysiology

Patellar maltracking, meniscus degeneration, knee osteoarthritis, quadriceps tendonitis, and patellar bursitis are common triggers. Poor running or squatting mechanics aggravate the condition.

Common symptoms include localized tenderness, sharp pain during movements, swelling, bruising, and muscular tightness or spasms in the affected region.

Evidence-Based Physiotherapy Treatment

Rehab focuses on: 1) Quadriceps strengthening (VMO focus) and gluteal activation, 2) Patellar mobilization and foam rolling the lateral structures (IT band), 3) Patella taping for patellar tracking support, and 4) Squat mechanics retraining.

Rehabilitation must be progressive, moving from pain reduction to strength restoration. Patients are advised to work under guided supervision to prevent reinjury.

Clinical Outlook & Next Steps

Early and accurate diagnosis is critical to avoid transforming acute tissue strains or nerve compressions into chronic dysfunction. If you suspect an injury, consult a physiotherapist for a personalized evaluation.
