Reconstruction of the Posterior Cruciate Ligament and Posterolateral Structures of the Knee
The purpose of this investigation is to determine the clinical outcome of surgical
reconstruction of complete ruptures to the posterior cruciate ligament (PCL) and
posterolateral structures of the knee joint. The outcome will be determined with validated
and rigorous knee rating systems between 2 and 10 years postoperatively. The results will be
determined by the analysis of subjective and functional factors, sports and occupational
activity levels, a comprehensive physical examination, and a radiographic evaluation. We
hypothesize that the appropriately indicated procedures will effectively restore normal knee
stability and function in patients with isolated or combined injuries to these structures.

Because injuries to the PCL and posterolateral structures occur with less frequency than
other structures in the knee joint (such as the anterior cruciate ligament and menisci),
fewer studies are available to assist the surgeon and patient with appropriate
decision-making regarding conservative versus surgical treatment. The majority of patients
who sustain injury to these structures are treated conservatively. Unfortunately, several
investigations describe noteworthy symptoms and functional limitations following
conservative management, and a high percentage of patients develop knee osteoarthritis that
can be disabling for both recreational and daily activities. The investigators of this study
have nearly three decades of experience and have extensively studied the effects of this
injury in both the laboratory and clinic settings. It is our opinion that surgical
reconstruction provides significant benefit when appropriately indicated, as has been
demonstrated in our previous studies. Especially in athletic individuals, PCL and
posterolateral reconstructive procedures have advanced to the point where more predictable
results can be expected to restore sufficient knee function. Studies have demonstrated, at
least in the short-term, that the majority of patients with acute ligament ruptures treated
with reconstruction are able to return to various levels of sports activities.12 Whether
these procedures will decrease the risk of the patient developing future osteoarthritis is
unknown and requires further study.
