Abstract
Purpose

To analyze the clinical results of collagen meniscal implants (CMIs) combined with tears of the anterior cruciate ligament (ACL).

Materials and methods

37 males and 1 female were followed up, with ages ranging between 22 and 50, who were subjected to an arthroscopic implantation of a CMI in the medial compartment of the knee associated with repair of the anterior cruciate ligament and the semitendinosus and gracilis tendons in 35 cases; in 3 cases an allograft was used. Ten of the patients presented with an injury in the lateral meniscus of the same knee. Time elapsed between injury to the ACL and surgery ranged between three weeks and six months. All patients were evaluated on the IKDC scale, as well as weight-bearing X-rays and NMRi. Follow-up was between 24 and 84 months.

Results

The IKDC score was normal in 19 patients (A), almost normal in 14 (B), abnormal in 4 (C) and severely abnormal in one (D). Range of motion was normal in 26 patients and near-to-normal in 12. KT-1000 was normal in 30 patients, near-to-normal in 5, abnormal in 1 and severely abnormal in 2. The weight-bearing X-ray study was normal in 24 patients, near-to-normal in 7 and abnormal in 7. As regards complications, 8 implants had reabsorbed at 6 months; there were 7 dysesthesias in the area of the saphenous nerve, one failed repair, one loss of a CMI and two instances of stiffness that required mobilization under anesthesia.

Conclusions

CMI is a functional alternative for young patients with severe meniscal lesions who also have an ACL tear. However, further study is necessary before it can be considered a generalized technique.

Resumen
Objetivo

analizar el resultado clínico de los implantes meniscales de colágeno (CMI) combinados con roturas del ligamento cruzado anterior (LCA).

Pacientes y método

se realizó el seguimiento de 37 varones y 1 mujer, con edades entre 22 y 50 años, a los que se implantó artroscópicamente un CMI en el compartimento medial de la rodilla asociado a plastia de ligamento cruzado anterior, semitendinoso y recto interno en 35 casos y con aloinjerto en 3. De los pacientes, 10 presentaban una lesión del menisco lateral en la misma rodilla. El intervalo de tiempo entre la lesión del LCA y la cirugía varió entre 3 semanas y 6 meses. Se evaluó a todos los paciente con la escala IKDC, radiografías en carga y resonancia magnética. La evolución fue entre 24 y 84 meses.

Resultados

el IKDC, en 19 de los pacientes fue normal (A), en 14 casi normal (B), en 4 anormal (C) y en uno severamente anormal (D). El rango de movilidad fue normal en 26 pacientes y cercano al normal en 12. El KT-1000 fue normal en 30 pacientes, casi normal en 5, anormal en 1 y severamente anormal en 2. El estudio radiográfico en carga fue normal en 24 pacientes, casi normal en 7 y anormal en 7. Como complicaciones encontramos 8 implantes reabsorbidos a los 6 meses; 7 disestesias en territorio del nervio safeno, una rotura de plastia, una pérdida del CMI y 2 rigideces que precisaron movilización bajo anestesia.

Conclusiones

el CMI es una alternativa funcional en pacientes jóvenes con lesiones meniscales graves que asocian roturas del LCA, pero requiere futuros estudios y desarrollos técnicos antes de ser generalizada.
