Table 1 The study characteristics

Ref.	Country	Study period	Study design	Patients (n)	Male/female	Mean age (years)	Follow-up (months)	Conclusion
Kumar et al[14], 2023	India	N/M	Prospective study	24	24/0	29.5	24	Arthroscopic single bundle PCL reconstruction using ipsilateral peroneus longus tendon autograft had significant improvement in functional outcome of the knee based on IKDC and Tegner Lysholm score. Ankle function was also found to be preserved based on Foot and Ankle Disability Index score at 2-years follow-up
Sharma et al[15], 2023	India	August 2019 to July 2020	Prospective study	12	9/3	N/M	18	Single bundle PCL reconstruction with peroneus long us tendon auto graft had improvement functional outcome (IKDC, modified cincinnati, Lysholm) and shown excellent ankle function and serial hop test result at 18 months evaluation
Faisal et al[19], 2022	Bangladesh	January 2018 and December 2019	Retrospective study	18	16/2	32	24	Peroneus longus tendon autograft used in PCL reconstruction had improved functional outcome (IKDC, Lysholm) and shown excellent ankle function and serial hop test result at two-year evaluation and can be encouraged as a graft of choice
Rhatomy et al[16], 2021	Indonesia	2014 and 2017	Prospective study	28	22/6	29.1	24	Peroneus longus tendon is a good choice as a graft in PCL reconstruction at the 2-year follow-up, with minimal donor site morbidity
Setyawan et al[17], 2019	Indonesia	October 2015 and June 2016	Prospective cohort study	15	11/4	25.86	24	Single bundle PCL reconstruction with peroneus longus tendon autograft had improvement functional outcome (IKDC, modified cincinnati, Lysholm) and shown excellent ankle function and serial hop test result at two-years evaluation
