We present 50 consecutive patients with chronic anterior cruciate defi
ciency treated by reconstruction of the ligament through a limited art
hrotomy using the middle third of the patellar tendon as a graft. The
patients were all men with a mean age of 26 years (range 17 to 36 year
s) with an average follow lip of 24 months. There were good or excelle
nt results as measured by the Lysholm score in 41, and in 27 with the
ARPEGE score. Movements were full in 46 and retropatellar pain was exp
erienced by 4.
