Overuse injuries are common in cyclists – anterior knee pain and patellofemoral pain.
Some of the evaluation considerations are:
Bike fit/Poor technique
Recent change in equipment
Individual anatomical factors
Overuse injuries occur when a tissue accumulates damage caused by repetitive submaximal loading. A specific structure fatigues – inadequate recovery follows and – microtrauma stimulates an inflammatory response. This leads to the sum of released vasoactive substances, inflammatory cells and enzymes that damage local tissue. Cumulative microtrauma from further repetitive activity will then have a clinical injury as a result.
In chronic cases, continued activity produces degenerative changes that lead to:
Loss of flexibility
Overuse injuries do not produce acute tissue inflammation BUT chronic degeneration or tendinitis
Most likely occurrences that can lead to this are changes in mode, intensity and duration of training
Biomechanical (intrinsic) factors and equipment or training (extrinsic) issues are the main contributors to overuse injuries.
Overuse Knee injuries are the result of heavy training loads & high mileage as well as rapid increase in training distance or intensity in the early season
Progressive strengthening exercises need to be done for the muscle weaknesses.
Knee pain in cycling caused through training :
Rapid increase in distance or intensity - Can possibly result in muscle tightness or microtrauna
Excessive hill work (on bike ) - Can possibly result in cartilaginous breakdown
Pushing high gear ratio - Can possibly result in medial knee stress
Hill running (on foot) - Can possibly result in medial knee stress (uphill), tight quadriceps (downhill)
Deep leg squats - Can result in increased stress on the entire knee
Knee pain in cycling caused by your anatomy :
Could possibly result in ITB stretch on shorter leg, posterior knee stress
Could result in lateral knee stress (increased Q angle)
Internal tibial rotation
Could have patellar misalignment as a result
And this can result in ITB syndrome
Muscle weakness of quadriceps, hamstrings,hip flexors, gluteus.
