“…This remnant may also lend blood supply to the graft along its length, possibly resulting in earlier incorporation and maturation of the graft. 12 Primary repair of the PCL allows for the reduction of native tissue to anatomic landmarks and possibly more rapid healing and ligamentization compared with reconstruction. 11 , 19 The addition of hamstring autograft augmentation may further protect the primary repair by maintaining the tibiofemoral relationship as an independent PCL reconstruction and by adding collagen to the construct without any of the complications of artificial material augmentation, namely, stress shielding, overconstraint, synovitis, and/or failure.…”

“… 4 , 24 Other authors recommended preserving the PCL remnant during reconstruction, citing improved graft maturation and earlier healing. 12 , 25 , 41 , 48 However, reconstruction with remnant preservation can be challenging because of decreased arthroscopic visibility. 25 , 41 , 48 Still, others advocate for primary PCL repair, citing the PCL's ability to heal and the importance of preserving native anatomic landmarks as guiding principles.…”

Background: Posterior cruciate ligament (PCL) injuries to the knee are uncommon, and ideal surgical management of these injuries is unclear. Current surgical techniques include PCL reconstruction with remnant debridement, remnant-preserving techniques, and primary PCL repair. Augmentation of PCL repairs and reconstructions has been proposed to protect repairs or grafts in the postoperative period. Purpose: To describe PCL repair with the hamstring autograft augmentation technique and examine our preliminary midterm outcomes from a sequential cohort of patients. Study Design: Case series; Level of evidence, 4. Methods: The authors identified patients at their institution who underwent remnant-preserving primary PCL repair with hamstring autograft augmentation for both isolated tears and tears associated with multiligament knee injury (MLKI). Patient-reported outcomes were evaluated at a minimum 2-year follow-up using the International Knee Documentation Committee (IKDC) subjective knee form, the 12-item Short Form Survey, and a custom return-to-play questionnaire. Patient-reported outcomes data were summarized, and the predictors of outcomes from the descriptive data and clinical measures were further examined. Results: A total of 23 patients with a mean follow-up of 5.3 years met the inclusion criteria. Of these patients, 87% were associated with MLKI. The mean IKDC score was 87.7. Approximately 83% of patients were able to successfully return to their sport or occupation. Among 19 athletes, only 2 reported being unable to return to their preinjury level of sport because of limitations from their PCL surgery. Patient-reported outcome scores and return to sport or occupation did not have a statistically significant association with age, sex, body mass index, time from injury to surgery, or follow-up time. Conclusion: Outcomes of our cohort with remnant-preserving primary PCL repairs with hamstring autograft augmentation demonstrated comparable clinical outcomes to previously published PCL data. The advantages of remnant preservation, primary repair, and augmentation with an independent hamstring autograft reconstruction are combined within this technique.
