CANALES-ZAMORA, OA et al. Complex multiligament knee injury associated with patellar tendon rupture. Acta ortop. mex [online]. 2020, vol.34, n.6, pp.417-421.  Epub 13-Jun-2022. ISSN 2306-4102.


Multi-ligament injury of the knee joint is defined as damage to two or more major ligaments. They are uncommon, with an incidence of ˂ 10:10,000. They constitute less than 0.02% of all orthopedic lesions. It is even less frequent to find an association of these with a complete rupture of the patellar tendon which presents with a prevalence of 2.4%.

Case report:

22 year old male; he presented a high-speed accident with a diagnosis of multi-ligament left knee injury stage V of Schenck associated with complete patellar tendon rupture treated in a single surgical time with ligament reconstruction, four weeks after traumatic event. A score of 88.5 was obtained after eight months with the IKDC 2000 form for the subjective functional evaluation of the knee.


The definitive surgical treatment is performed four weeks after the injury. This reduces the risk of instability. In our clinical case, the patient is integrated into the activities of his daily life after eight months. To validate this technique as effective or good for its use, a greater number of patients treated in the same way is required. It is, however, suggested to contemplate as a management option.


These types of lesions are infrequent with a prognosis reserved.
