Stepping into the Unknown: Unveiling the Rarity of PCL Fracture-Avulsions

Tears of the posterior cruciate ligament (PCL) are rare, and avulsion fracture of the tibial attachment of the posterior cruciate ligament is even rarer. These injuries usually occur in accidents such as car crashes, causing acute pain, swelling as well as total functional impotence of the knee. Studies on the incidence of these injuries show variable results, but there appears to be an upward trend. The surgical management of PCL avulsion fracture is not clearly established, although arthroscopic techniques are becoming more popular due to their potential benefits. However, some medical centers may have limited access to these methods, thus preferring open surgery options. A case of LCP avulsion fracture in a 36-year-old female patient was reported, and surgery was successfully performed, leading to full recovery after six months with full knee mobility and posterior stability.
