Aims And Objectives: To find out the incidence of ACL & meniscal injuries, to co-relate MRI findings with arthroscopy by calculating Sensitivity, Specificity, Positive And Negative Predictive Values (PPV & NPV) keeping arthroscopy as a gold standard, to find out the degree of subluxation and to grade it and to find a threshold value of fluid in knee.
Settings And Design: Prospective analytical study.
Materials And Methods: MRI of 230 patients with 71 arthroscopic co- relation in year 2012-14 was analysed.
Statistical Analysis: Descriptive statistics using Chi square test and predictive values was done. The spearman correlation coefficient was done by using statistical software SPSS 17.0.
Results: The sensitivity, specificity, PPV and NPV was calculated (in %). For ACL it was 87.87, 81.57, 80.55, 88.57 for MM 93.54, 87.50, 85.29, 94.59 and for LM 77.77, 81.81, 72.41, 85.71 respectively. We found 35.6% incidence of anterior tibial subluxation with maximum patients having grade 1 category subluxation. Two hundred and one cases showed joint fluid in lateral aspect of the suprapatellar pouch (AP diameter >10mm) with internal derangement.
Conclusion: MRI is helpful in diagnosing meniscal and cruciate ligament injuries. Arthroscopy still remains gold standard for definitive diagnosis.

Non-contact anterior cruciate ligament (ACL) rupture is a common serious orthopaedic disease in humans and dogs. Familial risk has been recognized in both species but interactions between genetic effects and environmental risk are not understood. We investigated ACL rupture heritability, genetic architecture, selection pressure, sharing of risk genes and biological pathways, and polygenic risk score (PRS) prediction of disease risk.

Background: The aim of this study was to predict intraoperative graft diameter with our new method by evaluating the cross-sectional areas (CSAs) of the hamstrings in axial sections of MRI.
Methods: This study included 78 patients who underwent single-bundle ACLR between 2022 and 2023. MRIs of the patients were evaulated preoperatively and four CSAs of the hamstring tendons were measured in two different regions by two participants.

Anterior Cruciate Ligament Revision Using Bone-Patellar Tendon-Bone Autograft and Lateral Extra-articular Tenodesis.

Revision of anterior cruciate ligament reconstruction presents various challenges not encountered in the primary settings, including malpositioned tunnels, tunnel widening, and the lack of consensus on the ideal graft to be used. This Technical Note describes a one-stage anterior cruciate ligament reconstruction revision using a bone-patellar tendon-bone autograft combined with lateral extra-articular tenodesis. This technique represents the ideal approach to tackle complex revision cases primarily characterized by tibial and femoral tunnel osteolysis and rotational knee instability.
