Works in progress #5. Total knee arthroplasty using a long-stem tibia component A novel approach to traumatic...

Constrained total knee arthroplasty (TKA) using a long-stem modular tibia component has been successful in three cases that presented an unusual combination of technical problems. The constrained TKA described allows successful salvage in patients with traumatic arthritis, extreme ligamentous damage, and either nonunion or the presence of multiple screw holes of the proximal tibia. The average follow-up period for these three cases has been only 18 months, but the results so far are very promising.
