Background:
Peroneus longus (PL) graft harvest has gained popularity in recent years for a variety of ligament surgeries. One of the common apprehensions regarding its more widespread usage has been the risk of injury to the common peroneal nerve or the sural nerve during graft harvest. The purpose of the current study is to assess the rate of injury to the peroneal and sural nerve following PL harvest using our technique in a large cohort of patients.
Materials And Methods:
A prospective cohort of 600 consecutive patients undergoing PLG harvest over a period from January 2022 to December 2022 at a single tertiary referral centre were included for analysis. Patients had baseline screening of nerve function prior to surgery and were regularly followed up at 3 weeks, 6 weeks, 3 months and 6 months post-harvest. Grouped variables for the sural and peroneal nerve were completed and analysis was carried out using Cochrane's Q test and McNemar's test.
Results:
We found that only 0.01% of patients had any nerve complications at 6 months follow-up, and three times more patients had sural nerve complaints than peroneal nerve complaints at the end of the 6 months follow-up.
Conclusion:
Peroneus longus harvest is a safe and reproducible technique with low complication rate. The rate of nerve complications post-harvest is grossly overestimated in the literature secondary to low-powered and low evidence studies. We believe that using our safe surgical technique for PL harvest with respect to surface landmarks allows for PL harvest with a low nerve complication rate.
