“…Attention has been drawn to possible errors that may arise from the manual location of femoral epicondyles [11]. There is also no experience in navigation in major deformities, and there is still very little in revision surgery [22]. Furthermore, even in experienced hands, and as our results show, the length of the surgery is at least 15 min longer than in conventional surgery.…”

We carried out a multicentre study to compare the postoperative femorotibial radiographic axis in two total knee replacement groups; one using manual instrumentation and the other using navigation. In the latter group, three navigation systems were used: Stryker, Orthopilot and Navitrack. The prior circumstances of patients in terms of age, weight, aetiology, epicondylar perimeter, patellar tendon length and knee deformity was similar in both groups. The duration of the operation was longer in the group with navigation (16.7 min). A normal femorotibial axis was more frequently obtained in the group with a navigator compared to the manual group (48.1% and 30%, respectively). A varus axis was most common in the manual group (42.2 and 26.

“…Five of the eight cases of aseptic loosening were in varus malalignment, implying that 230 knees in varus malalignment did NOT loosen.) The use of a malalignment index summing alignment measurements in three planes has been introduced by Sikorski [21]. The 3D assessment of alignment is now easily performed with tools such as the Perth CT knee protocol, and this should represent the gold standard in such studies.…”

The use of computer navigation and conventional techniques in total knee arthroplasty remains controversial. Advocates of computer navigated techniques cite better alignment of components and reduced morbidity associated with avoidance of intramedullary instrumentation as a rationale for their use. In contrast, proponents of conventional techniques argue that better alignment does not correlate with a better functional outcome and that the conventional approach avoids the perceived risk of fracture associated with bicortical insertion of navigation tracker pins.All total knee arthoplasties performed at our institution are prospectively monitored for life in a dedicated Joint Replacement Assessment Clinic (JRAC). Patients are reviewed by physiotherapists, independent of the surgeons who performed surgery, both preoperatively and at six weeks, three and six months, and one, two and five years postoperatively (and every five years thereafter). Patients are assessed using validated outcome measures (Knee Society Score, Western Ontario and McMaster Universities (WOMAC) osteoarthritis index, Short Form SF-36 Health Survey (version 2) and a patient satisfaction score). In addition, at 6 months post surgery, a CT scan of each implanted prosthesis is performed using the Perth CT knee protocol.The findings of a single unit's experience of 777 navigated primary total knee replacements are discussed and critically compared to the body of literature that currently relates to this controversial topic.

“…The definition of good and bad alignment is entirely arbitrary. Sikorski made an arbitrary unit that within 2˚ of neutral was defined as good alignment [21]. Some other authors also described that limb alignment after TKA to within 3˚ of the normal mechanical axis is important for good alignment in order for good post TKA outcome [22] The study conducted by Nathaniel F.R.…”

Total Knee Arthroplasty (TKA) is a procedure to replace the diseased or damaged knee joint with artificial prosthesis for the relief of disabling pain and restoring the function of knee. Total Knee Arthroplasty (TKA) is one of the most common and successful procedures in modern orthopedics and is spreading through the world. Many surgeons are developing their skill but it needs experience and patience for successful outcomes. There are different factors which affect the outcome after total knee arthroplasty, among them; the coronal alignment of lower limb plays a major role. Many studies have supported that neutral mechanical alignment after total knee arthroplasty leads to better function. The aim of this review is to evaluate clinical outcome with reference to the coronal alignment of the limb and safety based on Western Ontario and McMaster Universities (WOMAC), Knee Society Score (KSS) score.
