Tendon-bone incorporation of a tendon graft within the bone tunnel is of priority
concern when using for ACL reconstruction. Superior tendon graft-bone healing can
be achieved when periosteum was sutured on the tendon inserted into a bone tunnel.
This is a case series outcome study with surgical technique for single-bundle ACL
reconstruction with periosteum-enveloping hamstring tendon graft at 2-7 years followup.
Methods: From 2000 to 2005, ACL reconstruction with a periosteum-enveloping
hamstring tendon graft was performed on 368 patients (372 knees). Of those, 312
patients who complete at least two years of follow-up were included for analysis.
Four-strand periosteum-hamstring tendon grafts were used for single-bundle
reconstruction. Results: The 312 study patients were followed for an average of 4.6
(2-7) years. Their median Lysholm knee scores were 56 (40 to 70) and 95 (60 to 100)
points before and after surgery, respectively. After reconstruction, 85% of patients
could return to moderate or strenuous activity, 5.1 % exhibited grade 2 or higher
ligament laxity with anterior drawer test, and 6.1% had positive pivot shift. Complete
range of motion was achieved in 88% of patients. IKDC assessment rated 93% of
patients as normal or nearly normal. Conclusion: The study shows that satisfactory
results can be achieved with the periosteum-enveloping hamstring tendon graft in
single-bundle ACL reconstruction with minimal tunnel widening. Bone-tunnel
enlargement of more than 1 mm was identified in 5.4% of femoral tunnels and 6.1%
of tibial tunnels, which was less than in other studies using comparable fixation.
