Late reconstruction of patellar ligament ruptures using Ilizarov external fixation.
Overview
abstract
Chronic patellar ligament ruptures, on which failed reconstruction attempts have been made, cause structural changes in the quadriceps mechanisms with marked fixed proximal migration of the patella. Before reconstruction, the position of the patella must be normalized. When using Ilizarov principles and an Ilizarov external fixator to treat these ruptures, full weightbearing and range of motion can be maintained throughout the pre- and postreconstruction period. This previously unreported technique has been used in 2 patients with chronic patellar ligament ruptures in whom reconstruction attempts had failed. Successful results obtained with this procedure warrant its consideration for this rare but disabling problem.
