Cyclist's Knee - Relevant Anatomy[edit | edit source]
Most cyclists experience some knee pain over the cause in their riding career. A systematic review and various studies studies report the incidence of knee pain ranging from from 36% to 62%[1] [2]and it is the second most reported overuse injury for cyclists[3] (after Cyclist's Back).
The knee ( see the link for comprehensive detail of the knee) sits between the upper and lower leg. . If any part of the lower kinematic chain ( core, lumbar spine, hip, knee, ankle) gets a problem it can pull on the knee joint changing the way the knee functions and cause knee pain. Due to the repetitive motion of the knee in cycling overuse injuries can occur when these incorrect tensions/torsions are applied to the knee.
The knee joint is a complicated joint with various compartments that can be affected
Lateral and medial knee pain
Mechanism of Injury / Pathological Process[edit | edit source]
Four Main Reasons for Knee Pain on the Bike
- Incorrect cleat alignment
- Incorrect saddle position
- Incorrect cadence
- Poor flexibility and or strength of the core, pelvis and or flexors or extensors of lower limb kinetic chain[4]
Three Main Regions of Knee Pain
- Anterior Knee Pain. Caused by increased pressure on the patella and surrounding soft tissues or incorrect tracking of the patella. This can arise from: saddle too low or positioned too far forward; tight hip or knee flexors casing patella to compress at at patella femoral joint; slow cadence putting much great force through knee; cleats causing tibial torsion resulting in incorrect patella tracking.
- Posterior Knee Pain. Caused by increased forces applied to posterior knee joint and surrounding soft tissues. This can arise through: saddle too high or to far aft; tight calf, hamstrings or gluteals; cleats positions, foot too far forward on pedal.
- Lateral or Medial Knee Pain. Caused by incorrect pressure applied through lateral or medial knee structures[5] A 2018 systematic review reported that an increased medial projection of their knees causes an altered activation of the vastus medialis and vastus lateralis muscles and was a potential cause of cyclists knee pain[5].This can arise through: incorrect cleat alignment, toe pointing medial causing lateral stress, toe points lateral causing medial stress; tight medial or lateral structures eg TFL or thigh adductors; insufficient core or pelvic muscle power to stabilise pelvis for lower limb kinetic chain to function efficiently from.[4]
