IntroductionThe purpose of this study was to conduct a literature review of studies that have addressed rehabilitation after posterior cruciate ligament (PCL) reconstruction. In particular, we intended to perform categorical analysis and discuss some critical points.Materials And MethodsA literature review of English language articles was performed using the PubMed databases. Our literature search was performed using the following text words: [posterior cruciate ligament OR PCL] AND [reconstruction] AND [rehabilitation]. A total of 34 articles met our criteria and were included in the final systematic review. Rehabilitation protocols were reviewed and tabulated according to main rehabilitation protocol categories [range of motion (ROM), weight bearing, bracing, and strengthening].ResultsRanges of motion of 90° and 120° were allowed at 4-8 and 6-12 weeks postoperatively in 70 % of studies. Full weight bearing was delayed until 6 weeks postoperatively in 60 % of studies. Most studies (73 % of studies) used a brace for 6-8 weeks and active hamstring exercise was not allowed for 6-24 weeks postoperatively.ConclusionsThe review showed that flexion of 90° was allowed at around 6 weeks and prone passive flexion exercise or supine passive ROM exercise with posterior support was used to prevent a posteriorly directed force. Most authors used non-weight bearing or partial weight bearing in their rehabilitation programs, however it may be possible to perform active weight bearing in full extension or early flexion grades as soon as the soft tissue situation allows. Co-strengthening exercises could be recommended because these exercises produce co-contraction between the quadriceps and hamstring muscles with little posterior shear force.
