Does alignment of the limb and tibial width determine relative narrowing between compartments when planning mechanically aligned TKA?
We determined (1) the range of the hip-knee-ankle (HKA) angle in the native or pre-arthritic limbs of patients with a contralateral total knee arthroplasty (TKA); and when mechanical alignment is planned (2) the relationships between the HKA angle and the tibial width, and the relative narrowing between the medial and lateral compartments and (3) the effect of tibial width on the range of narrowing. ⋯ IV, therapeutic study.

Clinical and sonographic evaluation of subpectoral biceps tenodesis with a dual suture anchor technique demonstrates improved outcomes and a low failure rate at a minimum 2-year follow-up.
The purpose of this study was to evaluate the clinical outcomes and integrity of an open subpectoral biceps tenodesis using a dual suture anchor construct. ⋯ Subpectoral biceps tenodesis utilizing a dual suture anchor technique is a treatment option for SLAP lesions, partial thickness tears, subluxation, and tenosynovitis of the long head of the biceps with high rates of postoperative patient satisfaction, a low failure rate, and improved outcome scores. The presence of a concomitant rotator cuff tear did not influence clinical outcomes.

Observational StudyThe impact of canal flare index on leg length discrepancy after total hip arthroplasty.
The femoral stem should protrude from femur by an appropriate vertical distance to allow leg length equalization at hip arthroplasty; this distance depends on the size/shape of medullary canal and implant. The relationship between femoral morphology and achievability of leg length restoration is currently unclear. Our aim was to examine the impact of the femoral canal flare index (CFI) on the risk of leg length discrepancy (LLD) after total hip arthroplasty with different femoral stems. ⋯ Higher CFI increases the risk of clinically detectable postoperative LLD in single-wedge femoral stems with cementless metaphyseal fixation. CFI has no significant impact on LLD in femoral stems with cementless diaphyseal fixation or cemented fixation.

Does tranexamic acid increase the risk of thromboembolism after bilateral simultaneous total knee arthroplasties in Asian Population?
To ascertain whether tranexamic acid reduces the blood loss and transfusion rate and volumes; increase the prevalence of deep vein thrombosis (DVT); and investigate factors associated with DVT in patients undergoing primary bilateral total knee arthroplasties (TKAs) without use of chemical thromboprophylaxis. ⋯ The use of tranexamic acid reduces the volume of blood transfusion and does not increase the prevalence of DVT or PE in the patients who did not receive routine chemical thromboprophylaxis after primary bilateral simultaneous sequential TKAs in Asian patients.

Exchange nailing with enhanced distal fixation is effective for the treatment of infraisthmal femoral nonunions.
The treatment options for nonunions of infraisthmal femoral shaft fractures after internal fixation are controversial. Methods such as exchanging an existing nail with a nail of a larger size, dynamization, removal of the nail followed by plating, and bone grafting have all been reported. Among those options, exchange nailing seems to be the most popular choice. In this study, a Poller screw, or an additional interlocking screw, was used in conjunction with exchange intramedullary nailing. The purpose of this study was to evaluate the effectiveness of treating femoral shaft nonunions using insertion of a Poller screw or an additional interlocking screw in conjunction with intramedullary nail fixation. ⋯ Poller screws and additional interlocking screws, along with intramedullary nailing exchange, may be an effective and reliable alternative for treating infraisthmal femoral shaft nonunions.
