Population
12 patients who underwent anterior cruciate ligament reconstruction with the 4-strand semitendinosus tendon
Design
Case_series
Follow-up
average 15.8 months (range 9-22 months)
Key result
Contrast-enhanced magnetic resonance angiography demonstrated that branches of the middle and inferior genicular arteries provided blood supply to the graft in all 12 patients after ACL reconstruction.

Vascular status of hamstring ACL grafts remains investigational; leaves open whether revascularization affects clinical outcomes.
Observational (n=12)
Contrast-enhanced MRA effectively visualizes the revascularization of autogenous hamstring tendon grafts and bone tunnels after ACL reconstruction.
Arai et al. (2008) conducted an observational in Anterior cruciate ligament reconstruction (n=12). Contrast-enhanced magnetic resonance angiography was evaluated on Vascular status of autogenous semitendinosus grafts. Contrast-enhanced magnetic resonance angiography demonstrated that branches of the middle and inferior genicular arteries provided blood supply to the graft in all 12 patients after ACL reconstruction.
