in combination with the ACL’s can have excellent
and good results, similar to those of isolated ACL
reconstructions.

Objective: In 1992, we reported our incidence of
loss of extension (LOE) (>=10 ) to be 11.1% at 2
months postoperatively. By avoiding acute
surgery, we decreased our incidence to 1.7% in
1995. In 2000, the International Knee
Documentation Committee (IKDC) redefined a
nearly normal passive motion deficit
postoperatively to be a side-to-side difference
5 side-toside
difference in passive knee extension or the
need for repeat arthroscopy or a drop out cast to
alleviate LOE.
Results: The overall incidence of LOE was 25.3%
(58 of 229). Thirteen point three per cent (28 of
233) of patients required arthroscopy to recover
full extension. LOE was significantly associated
with preoperative extension (p
