Biking Injuries

Biking is a popular recreational activity. Compared to other recreational activities such as jogging, biking (cycling) is a low impact method to perform regular exercise and stay healthy, that rarely results in serious pain and injury. Small changes in bike setup influence riding position (trunk, neck, upper and lower extremities) and its kinematics which can often lead to biking injuries.


Several studies indicated that 85% of cyclists suffer chronic and overuse injuries such as neck pain, median nerve palsy and patellofemoral pain syndrome etc. Among these injuries, Wilber et al found 41.7% had knee problems. This is because the foot pronates during a pressure step down phase, delivering an internally rotating stress to the medial side of the knee. In addition, the knee joints withstand these internally rotating stresses up to 5000 times an hour while repetitively bending and extending. This slight but continuous stress can lead to chronic knee injuries.


For cyclists, the most common knee injury is patellofemoral pain syndrome. It is caused by excessive internally rotating stress to the knees during a pressure step down phase, weak vastus medialis (VMO), tight lateral retinaculum, or poor quadriceps flexibility and inappropriate seat set. Clinically, cyclists with patellofemoral pain syndrome experience limited patellar mobility and dull pain behind or around the patella induced by knee flexion.


Treatment of patellofemoral pain syndrome focuses on regaining anatomical alignment, muscular strength and flexibility. Preventing patellofemoral pain syndrome is better than treating it. Although correct seat, pedals and frame set-up could minimize the severity of chronic injury, this correction cannot totally avoid knee problems. Wearing a knee support is recommended to prevent patefellofemoral pain syndrome by decreasing excessive stresses to the knee joint.


LP Knee supports function to correct knee alignment and disperse excessive internally rotating stress to the knees during pedaling. The Extreme Knee Support with Posterior Reinforcement Straps (533CA) is made from high-quality CoolPrene® material which can withstand excessive stretch to muscles and ligaments and regulate skin humidity and temperature during exercise. Two flexible stays placed on the lateral and medial side of the knee support, provide effective support to stabilize anatomical and functional alignment and disperse excessive medial stresses to the knees which is the main factor in developing chronic knee injuries. In addition, oval reinforced patellar pad inserted in 533CA helps normalize patellar alignment at the rest position and patellar tracking during pedaling. The unique opposite fastening system provides continuous, comfortable compression to support weak knee joint. The combination of these unique characteristics in the LP 533CA provides comfortable and reliable stability to cyclists so they can enjoy riding without pain and injury.
