“…However, several drawbacks remain unsolved because postoperative morbidities, such as anterior knee pain on climbing stairs, after long periods of sitting, or while kneeling, have been reported [8,38,42]. Moreover, quadriceps or hamstring isokinetic strength deficits [9,36], postoperative range of motion restriction [17], late postoperative graft elongation and subsequent laxity [7,34,37], patellar tendon shortening or rupture [28,29], and patellofemoral osteoarthritis [38] have been reported, and the quadriceps tendon has been found to have potential advantages as a graft in these aspects [13,15,41,44]. This study has some inherent weaknesses because of its retrospective nonrandomized treatment selection and differing methods of graft fixation in the two groups.…”

The bone-patellar tendon-bone has been widely used and considered a good graft source. The quadriceps tendon was introduced as a substitute graft source for bonepatellar tendon-bone. We compared the clinical outcomes of anterior cruciate ligament reconstructions using central quadriceps tendon-patellar bone and bone-patellar tendonbone autografts. We selected 72 patients who underwent unilateral anterior cruciate ligament reconstruction using bone-patellar tendon-bone between 1994 and 2001 and matched for age and gender with 72 patients who underwent anterior cruciate ligament reconstruction using quadriceps tendon-patellar bone. All patients were followed up for more than 2 years. We assessed anterior laxity, knee function using the Lysholm and International Knee Documentation Committee scores, and quadriceps strength, the means of which were similar in the two groups. More patients (28 or 39%) in the bone-patellar tendon-bone group reported anterior knee pain than in the quadriceps tendon-patellar bone group (six patients or 8.3%). Anterior cruciate ligament reconstruction using the central quadriceps tendon-patellar bone graft showed clinical outcomes comparable to those of anterior cruciate ligament reconstruction using the patellar tendon graft, with anterior knee pain being less frequent in the former.Our data suggest the quadriceps tendon can be a good alternative graft choice. Level of Evidence: Level III Therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

rESUMOObjetivo: Avaliar a resistência e a regeneração do ligamento patelar após a retirada de enxerto para reconstrução do ligamento cruzado anterior, utilizando a técnica tradicional de incisão na pele única longitudinal e uma técnica de duas mini-incisões transversas, em ovinos. Métodos: Foram utilizadas 10 ovelhas. No joelho direito, realizamos a retirada do enxerto do ligamento patelar através do método tradicional e, no joelho esquerdo, através do método de duas incisões. Os animais ficaram em observação por seis meses. O conjunto (ligamento patelar, tíbia e a patela) foi adaptado à máquina de testes mecânicos para testes de resistência do ligamento. Resultados: Não foi encontrada diferença entre as duas técnicas propostas com relação à regeneração e resistência do ligamento patelar. Observamos, porém, o encurtamento do ligamento patelar nos dois grupos, e que a sutura da fascia superficialis do ligamento patelar não influiu na regeneração do ligamento patelar, segundo a histologia. Conclusão: A técnica utilizando duas incisões na pele apresenta os mesmos padrões de regeneração e resistência do ligamento patelar remanescente, quando comparada à técnica tradicional de incisão única longitudinal. descritores -

“…Shaffer and Tibone 31 in a prospective study of patients with arthroscopic reconstruction of the ACL using the middle third of the patellar tendon with the defect closed, found a mean of 2.28% of shortening of the tendon. Muellner et al 13 found no correlation of anterior knee pain with shortening of the patellar tendon.…”
