PCL injuries, although less common than ACL injuries, may be seen in variety of clinical settings. These can usually be diagnosed by the skilled physician through a thorough physical examination and confirmatory radiographic studies. Low-grade, isolated PCL injuries are usually treated nonoperatively with acceptable outcomes. Recent studies, however, suggest that chronic PCL deficiency may lead to progressive joint degeneration and arthritis. Multiple surgical options exist for reconstruction of the PCL, although there is little evidence to date demonstrating that PCL reconstruction significantly alters this natural history. Further research is needed to evaluate surgical techniques and treatment controversies.
