The incidence of femoral shaft fractures is on rise because of fast, high speed transportation and modern lifestyles. Internal fixation is the mainstay of treatment. Conventional plating is associated with high risk of infection, pseudoarthrosis, malunion, decreased knee motion and loss of fixation. Interlocking techniques lead to fewer complications of nonunion/malunion, lesser soft tissue dissection, earlier fracture healing and lesser chances of infection. Fractures in any zone from the subtrochanteric to distal supracondylar part of the femur are accessible to nailing. Materials and Methods:This was a prospective study of patients who underwent reamed intramedullary nailing for the fracture shaft of the femur. All patients were operated by the same surgeon and patients were followed up to six months period at regular intervals. Functional outcome is assessed by Thoresen's criteria and lower extremity functional scoring system. The study shall be of two and half years duration with effect from May 2015 to October 2017. Post operative evaluation was done at 1 month, 3 months and 6 months following surgery. Results: In our series of 78 cases of femoral shaft fractures treated by interlocking nail 57 patients had good outcome, 12 patients had moderate outcome, 5 had fair and 4 patients had poor outcome. Most of the patients in this series were younger age group; more than 80% were below 50 years. Conclusion: We confirm that the functional outcome after fracture shaft of femur stabilised by reamed intramedullary nail is good to moderate. Intramedullary nailing is effective treatment for the stabilisation of the fracture shaft of femur in view of subjective and objective perspective. Femur interlocking nail is a good implant for the treatment of femoral shaft fractures because of its load sharing, closed insertion, rotational stability, restoration of anatomic length alignment and early mobilization.

The knee joint is the most commonly injured of all joints and the anterior cruciate ligament is the most commonly injured ligament. Arthroscopic reconstruction of torn ACL has become the gold standard in treating ACL tears. The primary aim of this prospective randomized comparative study was to investigate whether an interference screw placed through the PT portal shows less divergence as compared with a screw placed through the AM portal. Materials and Methods: This is a randomized controlled study. 24 patients have been included in the study. Femoral tunnel-interference screw divergence will be measured on postoperative digital lateral Xrays. Ha's method will be used to grade divergence. The radiologist was blinded for the technique used (AM or PT portal).The clinical outcome will be assessed by postoperative intervention knee documentation committee grading (IKDC) and Lysholm score at two year follow up. The study shall be of two and half years duration with effect from May 2015 to October 2017. Results: In our series of 24 patients, mean age was 30.6 years.With respect to the IKDC scoring, 95.83 % patients had normal or nearly normal outcome and 4.16% had abnormal outcomes. We had 95.83 % excellent and good results with respect to Lysholm score, 4.16 % had fair outcome and we did not have any poor outcomes. In our study we had 12 patients in each group (AM and PT). The mean divergence in group 1 (AM portal) is 13.15 o . Mean angle of divergence in group 2 (PT portal) is 7.24 o Conclusion: Arthroscopic ACL reconstruction using bone-patellar tendon-bone autograft provides a stable knee with minimal complications. The short term results of femoral interference screw placement through the patellar tendon portal for arthroscopic ACL reconstruction using bone patellar tendon bone graft are encouraging with minimal screw divergence with a good clinical outcome.
