Comparison Between Allografts and Autografts
| Autografts | Allografts | |
|---|---|---|
| Origin | Hamstring tendon | BPTB composites |
| BPTB composites | Achilles tendon | |
| Quadriceps tendon | Tibialis anterior | |
| Tibialis posterior | ||
| Fascia lata | ||
| Hamstring | ||
| Advantages | Heal more quickly with long-term viability | No donor-site morbidity |
| Not involved in disease transmission or initiation of host's immune reaction | Less postoperative and long-term pain | |
| Inexpensive | Decreased operative time | |
| No special instrumentation for preservation | Better cosmetic appearance | |
| Lower failure rate | No functional impairment | |
| Lower infection rate | Large variety of graft sizes and shapes | |
| Fewer ethical and religious concerns | ||
| Disadvantages | Limited availability | Expensive |
| Increased operative time | Disease transmission | |
| Donor-site morbidity | Healing concerns | |
| Functional impairment (e.g. muscle weakness) | Unclear long-term viability | |
| Concerns about immune response and rejection | ||
| Lack of availability | ||
| Ethical and religious concerns |
