Is ACL reconstruction done with an allograft tendon?

An allograft is donor tendon tissue prepared for use as a ligament graft. During ACL reconstruction, the surgeon places the graft along the planned ligament path and secures it in the bone tunnels. Other reconstruction options use the patient’s own tendon, called an autograft. The decision considers sporting goals, age, previous operations, available tissue, knee stability, and the surgeon’s assessment. An allograft may avoid taking a tendon from another part of the same leg, but it has its own healing considerations.

Discuss the graft options before surgery and explain the activities you hope to resume. Ask how the graft will be fixed, what rehabilitation restrictions apply, and how the plan changes if meniscus or cartilage treatment is needed at the same time. Pre-operative physiotherapy may help restore knee motion, reduce swelling, and improve muscle control when appropriate. After reconstruction, follow the staged programme even if the knee feels better early; graft healing and neuromuscular recovery continue beyond the first phase.

Before surgery, obtain assessment for a locked knee, repeated giving-way episodes, or substantial swelling after an injury. After surgery, contact the care team for worsening pain, increasing redness or drainage, fever, new calf swelling, or sudden breathlessness. A new instability episode or inability to follow the rehabilitation exercises also deserves review.

Ask why an allograft or autograft is being recommended for you, what donor-tissue processing involves, how the choice fits your sport, and which milestones will determine return to running and pivoting activities.
