Key Restrictions

Same as BPTB plus: PWB with crutches x 6 wks; early return to sport phase delayed; allograft revascularization is slower than autograft

Timeline & Phases

6 phases: same as BPTB/hamstring entries; early return to sport phase delayed

Notes

Same document as BPTB/hamstring entries; notes allograft has slightly increased risk of graft failure with early high-level activity. [Archived copy — original Massachusetts General Hospital URL retired in the Mass General Brigham site migration; Wayback snapshot 2026-07-30.]
