Aim: The purpose of this research is to determine the Posterior Cruciate Ligament restoration utilising a peroneus longus tendon graft. Methods: This research comprised 20 individuals with chronic injury (> 6 months) and the presence of a 'isolated' PCL. Clinical examination and imaging were used to confirm the diagnosis of chronic ligament rupture (Magnetic resonance imaging, MRI). Two years following surgery, post-operative functional outcomes (IKDC, Modified Cincinnati, and Lysholm) were documented by direct patient examination and a guided interview by a single orthopaedic specialist outside the surgical team. Results: Intra operatively, graft diameter was measured and documented, yielding a mean diameter of 8.77± 0.88 mm. The pre-operative IKDC score was 48.75±11.69, while the post-operative score was 79.98±5.63. After a two-year follow-up. The mean Modified Cincinnati score was 49.86±9.58 before surgery and 81.69±2.36 after 2 years of follow-up. The pre-operative Lysholm score was 51.638.69, and the 2-year follow-up score was 82.44±5.22. There were significant differences in pre-operative and 2 years post-operative IKDC, Modified Cincinnati, and Lysholm scores (p 0.05), with the majority of patients with PCL damage rebuilt with peroneus longus tendon showing improvement. After 24 months, the single hop test and triple hop test showed 97.02± 3.21 and 93.12±3.06, respectively. Table 3 shows how ankle functional score, AOFAS, and FADI score are used to assess donor site morbidity. The average AOFAS score of the donor ankle was 95.61±1.97, while the FADI score was 95.89±1.78. Conclusion: At two years, single bundle PCL repair with peroneus longus tendon autograft improved functional outcome (IKDC, Modified Cincinnati, Lysholm) and demonstrated good ankle function and serial hop test results.
