Hypothesis 1: There is less tunnel-widening with bone–patella tendon–bone graft compared with the hamstring graft when the same fixation method is used. Tunnel widening is greater with achilles tendon allografts versus autograft bone-patella tendon-bone and hamstring autografts.

Hypothesis 2: Tunnel widening occurs in the early post-operative period (< 8 weeks) when the tendon remodels within the bone tunnels.

Hypothesis 3: Low pre-operative bone mineral density is associated with tunnel widening.
