Purpose To measure the femoral tunnel length created through a far medial portal and determine its correlation with body height, limb length, and thigh length in 404 Indian patients undergoing anterior cruciate ligament (ACL) reconstruction. Methods 364 male and 40 female Indian patients aged 18 to 51 (mean, 26.8) years underwent ACL reconstruction by a single surgeon using the hamstrings tendon autograft. Their body height, limb length, and thigh length were measured by a single assessor, as was the femoral tunnel length. Results The mean femoral tunnel length was 34.5 mm. It was <30 mm in 28 patients and <25 mm in 2 patients. The correlation coefficients of the femoral tunnel length with body height, limb length, and thigh length were 0.485 (p<0.0001), 0.426 (p<0.0001), and 0.304 (p<0.0001). No patient had posterior wall blowout fracture. Conclusion The femoral tunnel length positively correlated with body height, limb length, and thigh length in 404 Indian patients.

<p class="abstract"><strong>Background:</strong> One of the popular graft choices for ACL reconstruction have been Hamstrings tendon autograft. There is no consensus on the ideal technique of fixation of hamstrings graft to femoral condyle. Theoretically we hypothesized that transfixation method of hamstrings graft fixation to femoral condyle should be superior to bio-interference screw fixation technique. Hence aim of our study is to compare this two fixation methods of hamstrings autografts clinically.</p><p class="abstract"><strong>Methods:</strong> 50 clinically and radiologically proven ACL deficient fighting soldiers are selected for the study. In group A; 25 patients underwent ACL reconstruction with Bioscrew using aperture technique on femoral side. Other 25 patients in group B underwent ACL reconstruction with transfixation screw using cortico-cancellous fixation technique on femoral side. In both groups quadrupled semitendinosus autograft is utilized. All the patients evaluated for functional outcome at the end of 6 weeks and at 6 months and at the end of 1 year following the procedure. The subjects are evaluated using the modified Lysholm knee score and knee laxity is measured by Rolimeter.<strong></strong></p><p class="abstract"><strong>Results:</strong> At 01 year post op. there was no statistically significant difference in both groups in terms of Manual laity tests,Rollimeter laity measurement and Lysholm knee score.The overall satisfactory result (Excellent + Good) in both the groups at 01 year follow up were 98% by Lysholm score.</p><p><strong>Conclusions:</strong> Transfixation and Bioscrew fixation showed comparable results in manual knee laxity tests, instrumental knee laxity tests using Rolimeter, Lyslohm scores and high patient satisfaction, with almost 96% of patients in both groups returned to their pre-injury levels. </p>

<p class="abstract"><strong>Background:</strong> Various techniques and graft types are now available for the reconstruction of ACL. Opinions differ among experts with regard to the ideal technique and graft type to be used. Arthroscopic anatomical ACL reconstruction using quadrupled hamstring autograft with fixation in the femoral tunnel using tightrope and in the tibial tunnel with interference screw is a relatively new technique. Purpose of this study is to analyze the postoperative outcome in our experience with this procedure.</p><p class="abstract"><strong>Methods:</strong> This was a prospective study of patients with ACL injury who underwent Arthroscopic anatomical ACL reconstruction using quadrupled hamstrings autograft. All patients were operated upon by the same surgeon and had the same rehabilitation protocol. They were followed up for six months at regular intervals using IKDC, LGS scoring systems, tegner activity scale and a subjective questionnaire.<strong></strong></p><p class="abstract"><strong>Results:</strong> About 95% of the patients had a favorable outcome as per three scoring systems. (IKDC, Lysholm score, subjective questionnaire) all three scoring system had a very high correlation around 90% of individuals were able to return to their pre injury activity level.</p><p class="abstract"><strong>Conclusions:</strong> We conclude that the functional outcome of arthroscopic anatomical anterior cruciate ligament reconstruction using quadrupled hamstrings tendon autograft is excellent to good (95%). With proper patient selection and rehabilitation full occupational and recreational activities can be expected for most of the patients within four to six months of the procedure.</p>
