Total knee arthroplasty in patients with extra-articular deformity
نویسندگان
چکیده
Multiple acceptable options are available for the correction of distal femoral deformity associated with knee arthritis. The treatment modality should be chosen based on the extent of deformity and attention to preservation of the collateral ligaments. Surgical options range from osteotomy alone, arthroplasty with intra-articular correction, or arthroplasty with extra-articular correction. Different implant choices and fixation methods for the osteotomy possess advantages and disadvantages which need to be considered carefully. In addition to discussing principles of management based on current literature, this article includes a case report using a previously undescribed technique using corrective osteotomy, intramedullary nail fixation, and total knee arthroplasty with computer navigation.

Navigation-Assisted Total Knee Arthroplasty for Osteoarthritis with Extra-Articular Femoral Deformity and/or Retained Hardware
Total knee arthroplasty (TKA) for osteoarthritis (OA) patients with extra-articular deformity is still challenging because angular deformity, canal sclerosis, or the retained hardware that precludes the use of the traditional intramedullary guide. In addition, atypical bone cut for intra-articular correction leads to imbalanced soft tissue gap. Furthermore, corrective osteotomy should be consid...

PURPOSE Since the existence of an extra-articular deformity seriously alters the normal geometry and kinetics around the knee joint, difficulties are often encountered in total knee arthroplasty (TKA) using a standard surgical technique. The purpose of this study was to evaluate the usefulness of surgical navigation system as a treatment option for osteoarthritic knees with extra-articular defo...

Total knee arthroplasty (TKA) is the gold standard procedure for the end-stage destructive arthropathy of the knee. TKA can relieve pain and restore knee function. The post-operative mechanical axis should be within a +/-3 degree of a neutral mechanical axis to ensure a good long-term result and maximize the longevity of TKA. Performing TKA in patients with ipsilateral extra-articular deformity...

Long-term success on total knee arthroplasty (TKA) depends mainly on restitution of the limb’s mechanical axis and appropriate balance of soft tissue, as these factors optimize the load distribution to the interfaces [1-4]. Almost all patients with osteoarthritis have some degree of articular deformity, in varus or valgus, associated or not to certain ligament instability. In most cases, conven...
