Anterior cruciate ligament functional instability. A static intra-articular and dynamic extra-articular procedure

The static and functional results in a series of 50 patients evaluated at least two years after surgery were gratifying. None had any episodes of functional instability. Forty-six of the 49 who participated in sports prior to operation returned to all desired sports, including six patients who returned to intercollegiate and national team sports. The overall subjective and objective results were 30, excellent; 17, good; one, fair, and two, failure. Of the two failures, one had excellent static stability but significant pain due to pre-existing chondromalacia patella, and the other had a postsurgical neuroma at the lateral surgical site.
