Olecranization of the patella in posterior instability of the knee.

A case report is given in which temporary fixation of the patella to the tibia with a Steinmann pin was used in a patient with gross knee instability due to deficient cruciate ligaments. The pin was left in place for seven months, and at last follow-up--14 months postoperatively--marked improvement in knee stability was noted. The procedure is applicable as a means of maintaining reduction in posterior cruciate repairs and reconstructions.
