Abstract
The patella is the biggest sesamoid bone of the human body and translates the force generated by the quadriceps muscle to the lower leg. Full active knee extension is essential for walking and all daily activities. Thus, good extension strength is essential for a successful total knee replacement (TKR). Loss of knee extension, if a TKR is in place, often results in catastrophic outcomes. Therefore, prevention of violation to the extensor mechanism during TKR implantation is of high importance. Displaced patellar fractures or partial extensor tendon ruptures, but preserved extensor function, should be treated nonsurgically. Surgical repair always bears the risk of advanced extensor mechanism failure due to the limited healing capacity.
In total loss of knee extension due to complete Rupture of the quadriceps or patellar tendon or dislocated patellar fracture most of the time surgery is required.If surgical reconstruction is necessary, augmentation with autografts, allografts, xenografts, or synthetic material is recommended to increase solid scarring and to prevent failure. Reconstruction of chronic failure of the extensor mechanism is still regarded as salvage procedure to avoid knee arthrodesis.
