[Transplant selection for primary replacement of the anterior cruciate ligament].
Various graft choices have evolved over the past few decades for the primary reconstruction of the anterior cruciate ligament (ACL). Three predominant autologous graft choices exist today: patellar, hamstring, and quadriceps tendons. Clinical studies have as yet failed to demonstrate significant differences in clinical outcome among these grafts, irrespective of their varying fixation techniques. Therefore, other factors such as graft harvest morbidity have become more important when comparing different grafts. These factors can differ substantially between the grafts, depending on the type of patients' activities, the injury pattern, and the associated injuries of the knee joint. A basic knowledge of these factors and the parameters that affect the mechanical and biological behavior of the reconstructed ACL can help to find the appropriate graft choice for each individual patient. Factors such as harvest site morbidity, fixation techniques, osseous integration, and tunnel widening are discussed based on current clinical and basic science studies. Finally, an outlook is given for future alternatives with evolving techniques for tissue-engineered grafts, allografts, or the transplantation of xenogeneic donor tissue.
