Isolated rupture of the posterior cruciate ligament has a low incidence worldwide, a large number of series report it as one of the most under-diagnosed orthopedic pathologies in emergency services and outpatient clinics. The initial treatment is generally conservative, however there are patients who develop a chronic condition known as posterior knee instability. The ideal method of posterior cruciate ligament reconstruction should be reproducible and clinically successful. A modification to the anatomical technique of the Posterior Cruciate Ligament plasty has been developed, which consists of reinforcement with an adjustable synthetic implant that is anchored on the bone surfaces and fulfills the function of stabilization and reinforcement of the damaged native ligament, in this way faster clinical and functional recovery is achieved. The present work seeks to demonstrate the superiority of the GraftlinkⓇ All inside posterior cruciate ligament repair technique by means of reinforcement and augmentation with the internal braceⓇ system compared to conventional treatment. Data were collected by the surgeon (Felpe Jarquín Gil) and the concomitant (Ignacio Palafox Carral). Inclusion criteria: isolated injuries of the Posterior Cruciate Ligament. Seven patients (43.75%) underwent surgery with the Internal BraceⓇ technique, 9 patients (56.25%) without internal braceⓇ. Follow-up was carried out for 1 year. Patients in the group who underwent posterior cruciate ligament plasty with internal braceⓇ had a faster recovery compared to conventional treatment (p = 0.001). A higher incidence of moderate to severe symptomatology is observed in patients in the group treated with conventional repair, while patients treated with modified repair by reinforcement with internal braceⓇ presented predominantly mild symptoms or no symptoms, this clearly shows a difference in terms of residual symptomatology. Internal braceⓇ repair represents a viable, reproducible, reliable technique, with superior and proven efficacy for the treatment of posterior cruciate ligament rupture, and undoubtedly represents an excellent treatment option to optimize the clinical and functional results of patients. athletes.
