The purpose of this study is to determine whether intraoperative computer-assisted navigation improves prosthetic implant positioning as compared to conventional intraoperatve instrumentation in Total Knee Arthroplasty (TKA).
Primary data to be obtained is to determine whether mechanical axis of the limb malignment differs between patients whom have computer-assisted TKA and those treated with conventional intraoperative instrumentation.
Three months after surgery follow-up radiographic data will provide evidence on the initial implant position as determined with a series of x-rays including: full length standing, standard AP weight bearing, lateral, patellar, kneelingfilm views and CT evaluation. In addition, a correlation betweeen the CT measures and the kneeling x-ray can be performed at this time. Clinical (Knee Scale Society, WOMAC, and SF-36) data will also be obtained at the three month interval.

The functional flexion axis of the knee can be established by computer-assisted intra-operative data, through range of motion techniques, not specific landmarks such as epicondyles.
This is a prospective, randomised clinical outcomes study comparing the Signature Personalised Patient Care, Conventional Total Knee Arthroplasty and Computer Assisted Navigation, using Va...
Prospective, multicenter, observational, comparative clinical trial on the equivalence of two different OrthoPilot® navigation system generations applied for computer-assisted total knee ...
To compare the functional outcomes of Computer-Assisted Navigation (CAS) and Conventional Instrumentation TKA at the 8-year follow-up.
The objective of this study is to document the demographic and clinical characteristics and the long-term clinical outcomes of patients who require a total knee arthroplasty (TKA). The hy...
Patients with knee osteoarthritis may undergo total knee replacement too early or may delay or underuse this procedure. We quantified these categories of total knee replacement utilization in 2 cohort...
Custom-designed total knee replacement has become a standard procedure in some orthopaedic centres worldwide. Due to the lack of literature, the discussion about the hypothetical advantages has remai...
The goal of computer navigation in total knee arthroplasty (TKA) is to improve the accuracy of alignment. However, the relationship between this technology and implant longevity has not been establish...
We aimed to measure the period effect (change over time) in 30-day mortality after total hip arthroplasty (THA) and total knee arthroplasty (TKA) using data from the Australian Orthopaedic Association...
Total knee replacement is the treatment of choice in knee osteoarthritis. Despite this, there is still a percentage of unsatisfied patients. Recently, prosthetic designs have been developed to improve...
Replacement of the knee joint.
Replacement for a knee joint.
An instrument used to assess the results of rehabilitation from knee injuries, especially those requiring ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION. It measures recovery of knee joint function based on ACTIVITIES OF DAILY LIVING.
Partial or total replacement of a joint.
Injuries to the knee or the knee joint.
Arthroplasty is a surgical procedure to restore the integrity and function of a joint. A joint can be restored by resurfacing the bones. An artificial joint (called a prosthesis) may also be used. Various types of arthritis may affect the joints. Osteo...
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
