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.

Abstract Background: Cortical suspensory femoral fixation is commonly performed for graft fixation of the femur in anterior cruciate ligament (ACL) reconstruction using hamstring tendons. This study aimed to compare the morphology of femoral tunnel and graft insertion between fixed-length loop devices (FLD) and adjustable-length loop devices (ALD) using computed tomography (CT) images on the first day after hamstring ACL reconstruction. Methods: Overall, 94 patients who underwent ACL reconstruction from January 2016 to January 2021 were included. For femoral graft fixation, FLD (Smith & Nephew, ENDOBUTTON) and ALD (DePuy Synthes, Mitek sports medicine, RIGIDLOOP Adjustable cortical system) were used in 56 and 38 patients, respectively (FLD and ALD groups). For evaluation of the morphology of the humeral tunnel and graft depth, CT scans were performed immediately on the first postoperative day. The gap distance between the top of the graft and the socket tunnel end, the length of lateral bone preservation, and the depth of graft insertion were measured on the CT images. Results: The gap distance and bone preservation significantly differed between the two groups (1.90±1.81 mm and 14.35±4.67 mm in ALD groups; 7.08±2.63 mm and 7.35±3.62 mm in FLD groups, respectively; both P values < 0.01). The graft insertion depth did not significantly differ between the groups. Conclusion: The ALD group had a smaller gap distance, better bone preservation, and a similar graft insertion length in the femoral tunnel when compared to the FLD group. Based on these findings, ALD might be better for bone preservation and tunnel utilization in patients with short femoral tunnels. Trial registration: retrospectively registered

Abstract Purpose The effect of bone marrow mesenchymal stromal cells (BMSCs) and platelet-rich plasma (PRP) on tendon allograft maturation in a large animal anterior cruciate ligament (ACL) reconstruction model was reported for the first time. It was hypothesised that compared with non-augmented ACL reconstruction, BMSCs and PRP would enhance graft maturation after 12 weeks and this would be detected using magnetic resonance imaging (MRI). Methods Fifteen sheep underwent unilateral tendon allograft ACL reconstruction using aperture fixation and were randomised into three groups (n = 5). Group 1 received 10 million allogeneic BMSCs in 2 ml fibrin sealant; Group 2 received 12 ml PRP in a plasma clot injected into the graft and bone tunnels; and Group 3 (control) received no adjunctive treatment. At autopsy at 12 weeks, a graft maturation score was determined by the sum for graft integrity, synovial coverage and vascularisation, graft thickness and apparent tension, and synovial sealing at tunnel apertures. MRI analysis (n = 2 animals per group) of the signal–noise quotient (SNQ) and fibrous interzone (FIZ) was used to evaluate intra-articular graft maturation and tendon–bone healing, respectively. Spearman’s rank correlation coefficient (r) of SNQ, autopsy graft maturation score and bone tunnel diameter were analysed. Results The BMSC group (p = 0.01) and PRP group (p = 0.03) had a significantly higher graft maturation score compared with the control group. The BMSC group scored significantly higher for synovial sealing at tunnel apertures (p = 0.03) compared with the control group. The graft maturation score at autopsy significantly correlated with the SNQ (r = − 0.83, p < 0.01). The tunnel diameter of the femoral tunnel at the aperture (r = 0.883, p = 0.03) and mid-portion (r = 0.941, p = 0.02) positively correlated with the SNQ. Conclusions BMSCs and PRP significantly enhanced graft maturation, which indicates that orthobiologics can accelerate the biologic events in tendon allograft incorporation. Femoral tunnel expansion significantly correlated with inferior maturation of the intra-articular graft. The clinical relevance of this study is that BMSCs and PRP enhance allograft healing in a translational model, and biological modulation of graft healing can be evaluated non-invasively using MRI.

<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>
