Abstract
Fifteen chronic anterior cruciate ligament-deficient knees were arthroscopically reconstructed
with a semitendinosus tendon polypropylene (STP) augmented composite graft. A comparison
group of 28 reconstructions with the semitendinosus tendon (ST) but without augmentation
was simultaneously reviewed. The mean follow-up in the STP group was 31 months (range
of 24–42 months) and in the ST group it was 34 months (range 26–54 months). Both patient
groups had similar age, sex, preinjury functional sports level, injury-to-surgery
interval, and associated meniscal pathology. Good-to-excellent subjective results
were reported in 86% of STP patients and 78% of ST patients, whereas 86% of the STP
patients and 88% of the ST patients returned to sports activity. Objective examination
revealed 73% of the STP group and 82% of the ST group to have a negative or 1 + Lachman
test result. A negative pivot shift was noted at follow-up in 80% of the STP group
and in 82% of the ST group. KT-1000 testing revealed 60% of the STP patients and 61%
of the ST patients to have ≤3 mm of side-to-side difference. In the STP group there
was no evidence of graft breakage, deep infections, or sterile effusions. Overall
subjective and functional results were uniformly better than objective results in
both patient groups. Analysis of subjective, objective, and functional results reveal
no difference in outcome between the STP and the ST patient groups.
