Abstract
Objective

The aim of this work is to investigate whether the application of platelet-rich plasma (PRP) with a high fibrin content in the repair area of massive rotator cuff tears treated using arthroscopic techniques improves the functional results and decreases the number of re-tears.

Material and method

This prospective, randomised study included 28 patients (20 females and 8 males) with a mean age of 65 years (range: 53 to 78) and diagnosed with a massive rotator cuff tear (two tendons affected, >5cm). A complete single row arthroscopic repair of the rotator cuff was performed on all patients. A concentrate of platelet rich plasma with a high fibrin content was applied to the osteotendinous transition area in 14 patients after the operation, whilst in the other 14 patients the repair was performed without any growth factor support. The functional results were evaluated with the Constant scale, as well as an arthro-MRI to check the integrity of the repaired tendon one year after the operation.

Results

There were no complications or repeat operations in any of the two groups. The pre-operative Constant results improved 30 points in the group without PRP and 26 points in the group with PRP, with no significant differences between both groups. In the arthro-MRI study, integrity of the repair was observed in 9 (32%) patients, whilst 4 had a contrast leak and 15 a clear re-tear. No differences were found in the number of re-tears between the group in which the platelet-rich plasma was applied and in the one where it was not applied.

Conclusions

The arthroscopic repair of massive rotator cuff tears gives clinically satisfactory results, despite a high rate of new tears. The application of platelet-rich plasma did not improve the clinic results or decrease the number of re-tears.

Resumen
Objetivo

El objetivo de este trabajo es investigar si la aplicación de plasma rico en plaquetas con alto contenido en fibrina a la zona de reparación de roturas masivas del manguito de los rotadores tratadas mediante técnicas artroscópicas mejora los resultados funcionales y disminuye el índice de reroturas.

Material y método

28 enfermos (20 mujeres y 8 varones) con una edad media de 65 años (rango: 53 a 78) diagnosticados de una rotura masiva del manguito rotador (dos tendones afectados > 5 cm) fueron incluidos en este estudio prospectivo y aleatorizado. En todos los enfermos se realizó una reparación completa artroscópica del manguito rotador con técnica de una hilera. En 14 pacientes una vez finalizada la reparación se aplicó en la zona de transición osteotendinosa un concentrado de plasma rico en plaquetas y alto contenido de fibrina, mientras que en 14 enfermos se realizó la reparación sin ningún aporte de factores de crecimiento. Se evaluaron los resultados funcionales con la escala de Constant al año de la intervención, así como una artro-RM para comprobar la integridad del tendón reparado.

Resultados

No hubo complicaciones ni reoperaciones en ninguno de los dos grupos. El Constant preoperatorio mejoró 30 puntos en el grupo sin PRP y 26 puntos en el grupo con PRP, sin diferencias entre ambos grupos. En el estudio de artro-RM 9 pacientes mostraban integridad de la reparación (32%), 4 presentaban una fuga de contraste y 15 una rerotura franca. No se encontraron diferencias en índice de reroturas entre el grupo en el que se aplicó plasma rico en plaquetas y en el que no.

Conclusiones

La reparación artroscópica de roturas masivas del manguito rotador ofrece unos resultados clínicos satisfactorios a pesar de un elevado índice de nuevas roturas. La aplicación de plasma rico en plaquetas no mejora los resultados clínicos ni disminuye el índice de reroturas.
