Purpose This study aimed to evaluate the differences in clinical outcome and donor site morbidity between the Peroneus Longus Tendon (PLT) and Hamstring Tendon (HT) in single-bundle Posterior Cruciate Ligament (PCL) reconstruction. Methods Patients with an isolated PCL injury underwent single-bundle PCL reconstruction using consecutive sampling. Patients were allocated into two groups (PLT and HT) and prospectively observed. The tendon graft diameter was measured intraoperatively. Functional scores (IKDC, Lysholm, and modified Cincinnati scores) were recorded preoperatively and 2 years postoperatively. The thigh circumference and functional score according to the Foot and Ankle Disability Index (FADI) and American Orthopedic Foot and Ankle Society (AOFAS) were recorded to evaluate the morbidities in the ankle. Results Fifty-five patients (hamstring n  = 27, peroneus n  = 28) met the inclusion criteria. The diameter of the PLT graft (8.2 ± 0.6 mm) was comparable to that of the HT graft (8.3 ± 0.5 mm). Both groups had excellent postoperative knee functional outcome scores. The mean AOFAS and FADI scores were excellent, with no difference in thigh circumference between the groups. Conclusion PLT is a good choice as a graft in PCL reconstruction at the 2-year follow-up, with minimal donor site morbidity. Level of evidence II.
