Proper component positioning is essential for successful total knee arthroplasty (TKA). Femoral component positioning presents a technical challenge when significant femoral deformity is present. Most commonly, an intramedullary guide is used to make an accurate distal femoral cut. However, in the presence of a significant femoral deformity, this is not a viable option.The use of clamshell oste...

  A 25 year-old man presented with pain, swelling, and intermittent drainage from distal lateral aspect of his left knee three months after undergoing isolated ACL reconstruction with arthroscopic hamstring autograft and endobottom technique. His surgeon at that time tried to eliminate the pathology through arthroscopic wash out in two attempts. However, the pain, edema, and discharge recurred ...

Background: Femoral version abnormalities can contribute to intra-articular hip pathology. Combined arthroscopy with femoral derotational osteotomy (FDRO) has been shown successfully treat those pathology excessive anteversion or retroversion of the femur. Indications: We describe technique for combined and FDRO in patients symptomatic setting Technique Description: Hip is performed using stand...

Osteotomy procedures around the knee can alter the biomechanical axis of the knee, thereby shifting the load from one compartment to another. This can be used to unload an arthritic painful compartment or to decrease the weight experienced by a cartilage restoration procedure. Recent clinical and biomechanical studies have emphasized the importance of correcting the weight bearing axis in a car...

  Background: There are few studies comparing the biomechanical properties of angled blade plate and locking compression plates in supracondylar osteotomy. In the current randomized study, we prospectively compared the clinical and radiological outcomes of supracondylar osteotomy using these two plates. Methods: Forty patients with valgus knee malalignment were randomly assigned to two equal nu...

Background Distal femoral osteotomies (DFO) can be used to correct deformities around the knee. Although osteotomies can be fixed with either internal or external fixation techniques, the advantages of one over the other are unclear. Questions/purposes We asked whether (1) for both techniques, we could accurately correct the deformities based on our preoperative goals for mechanical axis deviat...

OBJECTIVES The development of computer-assisted surgery in total knee arthroplasty continues its search for better accuracy in the spatial positioning of prosthetic components and in achieving the best ideal ligament balance. Many studies have underscored the value of computer-assisted navigation in obtaining precise bone cuts in terms of both orientation and location, which would optimize bone...

Interruption of the blood flow may occur in intra-osseous arteries within the femoral head. We report a 72-year-old woman who developed osteonecrosis of the femoral head 11 months after surgery involving massive cementing of a segmental distal femoral rotating hinge prosthesis to treat nonunion of the distal femur. The bone cement filled the cavity up to the femoral neck and the superolateral p...
