How Foot Pronation Can Cause Patella Tendon Pain

When your foot rolls inward excessively—a movement known as overpronation—it does not just affect your arch. Because the bones of the foot and lower leg are connected, your foot alignment directly influences the mechanics of your ankle, shin, and knee.

If you experience soreness just below your kneecap, excessive foot pronation could be contributing to the strain placed on your patellar tendon.

The Kinetic Chain: From Arch to Knee

When your foot pronates and the arch flattens under load, the lower leg bone (tibia) internally rotates. This inward twisting motion alters the angle at which the forces pass through your knee joint. As the leg turns inward, extra stress and pull are placed on the patellar tendon, which connects the kneecap to the shinbone. Over time, this repetitive mechanical strain can cause irritation and pain around the front of the knee.

Addressing Alignment with Orthotic Support

Managing patellar tendon discomfort often involves looking at foot function. Podiatrist-designed orthotic insoles help support the medial arch and stabilise the heel, limiting excessive inward rolling. By helping keep the foot in a more neutral position, orthotics reduce unnecessary internal rotation of the tibia, allowing the knee joint to track more naturally and reducing strain on the tendon.

Key Biomechanical Insights

  • Excessive foot pronation forces the lower leg to rotate internally.
  • Inward rotation creates misaligned stress across the kneecap and patellar tendon.
  • Proper arch support helps stabilize the foot and maintain lower limb alignment.
  • Reducing overpronation can help manage repetitive loading strain on the knee.
Podiatrist TipCheck the soles of your shoes. Excessive wear on the inner side of the heel or tread often signals overpronation that may be affecting your knees.
