Purpose A peroneus longus tendon autograft is used in many orthopaedic procedures and it is biomechanically comparable to a hamstring tendon autograft. Despite its potential, there are few studies that have evaluated the use of the peroneus longus tendon in ACL reconstruction. The aim of this study was to compare the clinical outcome and donor site morbidity of ACL reconstruction with hamstring tendon autografts versus peroneus longus tendon autografts in patients with an isolated ACL injury. Methods Patients who underwent isolated single-bundle ACL reconstruction were allocated to two groups (hamstring and peroneus longus) and observed prospectively. Graft diameter was measured intraoperatively. Functional scores (IKDC, modiied Cincinnati and Lysholm scores) were recorded preoperatively and 1 year after surgery. Donor site morbidities were assessed with thigh circumference measurements and ankle scoring with the AOFAS and FADI. Results Fifty-two patients (hamstring n = 28, peroneus n = 24) met the inclusion criteria. The peroneus longus graft diameter (8.8 ± 0.7 mm) was signiicantly larger than the hamstring diameter (8.2 ± 0.8 mm) (p = 0.012). There were no signiicant diferences between the pre-and 1-year postoperative score between the hamstring and peroneus longus groups in the IKDC (n.s), modiied Cincinnati (n.s), and Lysholm (n.s). The mean for the AOFAS was 97.3 ± 4.2 and for the FADI 98 ± 3.4 in the peroneus longus group, with a signiicant decrease in thigh circumference in the hamstring group (p = 0.002). Conclusion Anterior cruciate ligament reconstruction with peroneus longus autografts produces a functional score (IKDC, modiied Cincinnati, Lysholm) comparable to that of hamstring autografts at a 1-year follow-up, with the advantages of larger graft diameter, less thigh hypotrophy and excellent ankle function based on AOFAS and FADI scores.

BackgroundAnterior Cruciate Ligament (ACL) is the most common ligament injury during sports activities that was treated with ACL reconstruction. Nowadays, peroneus longus is used in ACL reconstruction. However, it is difficult to predict the peroneus longus graft diameter for ACL reconstruction. Thus, preoperative measurements are very important to predict peroneus longus autograft for ACL reconstruction.MethodsA cohort retrospective study was conducted using consecutive sampling method from February 2016 until October 2017 in our center. We recorded patients’ characteristics include gender, age, body weight, height, and Body Mass Index (BMI) preoperatively. We measured peroneus longus graft diameter intraoperatively, and analysed data using Spearman correlation.ResultsThirty-nine patients met inclusion criteria. There were 28 males and 11 females in the peroneus group. From the patients' mean characteristics, age was 25.10 ± 9.16, body weight 71.23 ± 14.17, height 169.13 ± 8.81, and BMI 20.96 ± 3.44. Intraoperative peroneus longus diameter measurement was 8.56 ± 0.82. Spearman correlation showed significant correlation between intraoperative peroneus longus diameter with patient's height, body weight, and BMI with p < 0.05.ConclusionPatients’ characteristics including gender, height, weight, and BMI in preoperative measurements can predict peoneus longus graft diameter intraoperatively.
Anterior Cruciate Ligament (ACL) is a knee ligament that is very important in maintaining the stability of the knee joint. The incidence of isolated ACL tears remain a common orthopaedic injury with significant increase in the rate of ACL reconstruction over time. Several types of autografts used for ACL reconstruction have some potential occurrence of donor site morbidity, including Bone-Patellar Tendon-Bone (BPTB), hamstring tendon, and quadriceps tendon. Peroneus longus tendon can be an option as a graft donor because it has biomechanical characteristics that are not significantly different from the hamstring tendon. Purpose: The aim of the study was to evaluate the functional outcome and donor site morbidity of anterior cruciate ligament (ACL) reconstruction using peroneus longus tendon autograft. Methods: This study was an observational analytical with retrospective cohort design using medical record. The functional outcomes were assessed with IKDC, Modified Cincinnati, Tegner-Lysholm, and KSS scoring system 12 months after surgery. Donor site morbidity was assessed with AOFAS and FADI scoring system, eversion strength, and plantarflexion strength. Results: Seventy five patients fulfilled the inclusion criteria (59 males and 16 females). Mean of peroneus longus tendon graft diameters were 8.39 ± 0.69 mm (range 6.5-10 mm). Significant increase of functional score (p<0.05) were found 12 months after surgery. Mean score of IKDC was 55.26 ± 12.76 preoperative; 96.69 ± 3.36 postoperative, Modified Cincinnati was 65.45 ± 16.25 preoperative; 93.29 ± 7.04 postoperative, Tegner-Lysholm was 67.80 ± 15.29 preoperative; 89.71 ± 8.35 postoperative, KSS (Knee) was 65.33 ± 19.46 preoperative; 95.17 ± 5.94 postoperative, and KSS (Function) was 76.52 ± 20.25 preoperative; 93.20 ± 10.29 postoperative. Mean score of AOFAS was 98.93 ± 3.11 and FADI was 99.80 ± 0.59 at six months after surgery. The eversion and plantarflexion strength were not significantly different (p>0.05) between donor and contralateral side ankle. There was neurapraxia in 3 (4%) patients at six months postoperative. Conclusion: The peroneus longus tendon can be an ideal source of graft for ACL reconstruction because it has good functional outcome and minimal donor site morbidity.
