Final Grant Proposal Presentation 2

ACL graft comparison between patellar autograft, hamstring autograft and allographs

By: David T. Payne IV

ACL • Anterior translation of the tibia, and

secondary to varus/valgus stress. • Age, knee joint laxity, activity level,

biomechanics, may lead to ACL tear• Most frequently repaired ligament in

the knee joint.

Patellar Tendon Graft • Most widely used graft source and is

considered the gold standard.• Most popular choice due to the

strength, ease of harvest, quick healing, and good patient outcomes.

• Patella infera, patellar fractures, patellar tendon ruptures, tendonitis, anterior knee pain, synovitis

Hamstrings Autograft• Semitendinosus muscle is most often

used.• Recreational athletes, low demand

patients, or youth• Should not be used in competitive

sprinters, those with generalized ligamentous laxity, or those with previous hamstring injury

Allografts• Eliminates the donor morbidity and no

weakening of muscles • There is a shorter operating time, less

pain, smaller incisions, and better cosmetic result.

• Host immune response against donor tissue and an increase in cost.

PurposePatients need to know the differences

between the choices for the repair graft.College athletes are highly active and

will want to know how each graft will handle long-term stress

HypothesisResearch shows that patellar autografts

(BPTB) work best for highly active persons, including our college athletes

Comparing data groups such as success rate, rupture rate, pain levels, ect.

Inclusion Criteria College aged athletesUndergone patellar autograft, allograft

or hamstring autograft to repair ACL injury

Within the past 3 years

Exclusion Criteria College aged individuals that are not

athletes that have had one of the procedures.

Greater than 3 years since reconstruction

Any athlete with other surgeries
