Abstract

Background

Posterior cruciate ligament injuries can occur as isolated ligament ruptures or in association with the multiligament-injured knee. Delayed reconstruction, at 2–3 weeks post-injury, is predominantly recommended for posterior cruciate ligament tears in the multiligament-injured knee. While acute bone and soft tissue avulsion patterns of injury can be amenable to repair, the described techniques have been associated with some difficulties attaching the avulsed ligament.

Description of Technique

As part of a reconstruction/repair of a multiligament-injured knee, we performed arthroscopic primary repair of the posterior cruciate ligament by passing Bunnell-type stitches into the substance of the ligament using a reloadable suture passer. We then passed the sutures through drill holes into the femoral footprint of the ligament and tied them over a bony bridge.

Patients and Methods

We retrospectively reviewed three patients with posterior cruciate ligament tears associated with a multiligament-injured knee. All patients had posterior cruciate ligament soft tissue avulsions or “peel off” injuries diagnosed by MRI. The described repair technique was used to repair the posterior cruciate ligament avulsion. Minimum followup was 64 months (mean, 68 months; range, 64–75 months). ROM, stability testing, and functional outcome scores (Lysholm and modified Cincinnati) were recorded.

Results

Mean ROM was 0° to 127°. Posterior drawer testing was negative in all three patients. The mean Lysholm score was 92 and the mean modified Cincinnati score was 94. Followup MRI confirmed ligament healing in all patients.

Conclusions

We believe arthroscopic posterior cruciate ligament repair for soft tissue peel off injuries is a technique that, when applied to carefully selected patients, may be helpful to the surgeon treating patients with a multiligament-injured knee.
