ACL reconstruction in 2026: graft choices, demystified

Anterior cruciate ligament reconstruction is one of the most common sports surgeries performed today. The original ligament is replaced with a graft, and the choice of graft has a real effect on recovery, return to sport, and long-term knee health. Despite what you may read online, there is no single 'best' graft. The right choice depends on the patient, the sport, and the surgeon's experience.

The three most common graft options are bone-patellar tendon-bone (BPTB), hamstring tendons, and quadriceps tendon. Each has clear advantages and trade-offs.

BPTB has the strongest historical track record, especially for high-level athletes who need a rigid fixation and predictable return to pivoting sports. It heals reliably into the bone tunnels and is associated with a lower retear rate in younger, competitive patients.

The downside is anterior knee pain. Some patients find kneeling uncomfortable for months or years after surgery, and there is a small risk of patellar fracture. We tend to reserve BPTB for patients under 25 who play cutting or pivoting sports and have no history of kneecap pain.

Hamstring autografts are the most common choice in many parts of the world. They produce less anterior knee pain and preserve the patellar tendon, so kneeling is rarely an issue. The scar is smaller and the initial postoperative pain is usually milder.

The trade-off is a slightly higher retear rate in very young athletes, and a small reduction in hamstring strength that can be noticeable in sprinting or jumping sports. Hamstring grafts are often our first choice for recreational athletes, older patients, and those who want the quickest early recovery.

Quadriceps tendon grafts have gained popularity over the last decade. The tissue is strong, the harvest leaves the patellar tendon untouched, and early studies show favourable outcomes for both return to sport and knee comfort.

It is a good middle ground for patients who want the strength of a central graft without the anterior knee pain risk of BPTB. We consider it for active patients of all ages, especially those with a history of patellar tendinopathy or kneecap issues.

In our clinic, graft selection is a shared decision. We discuss age, sport, work demands, previous knee problems, and personal preferences. For a 19-year-old footballer, BPTB or quadriceps tendon may be preferred. For a 40-year-old recreational runner, hamstring is often ideal. For revision cases, allograft or quadriceps tendon may be used depending on what was done before.

The surgeon's technical familiarity also matters. A graft that the surgeon uses frequently and trusts will usually outperform one used only occasionally. If you are considering ACL reconstruction, ask your surgeon specifically why they recommend one graft over another for you.
