“…A randomized comparative trial by Cip et al demonstrated no difference in clinical outcome parameters between computer-assisted arthroplasty and conventional TKA after 5 years of follow-up. 16 Although there was no occurrence of pin tractassociated complications in this study, literature describes the incidence of pin tract-related femoral and tibial fractures at 1.3% and 1.4%, respectively. 17 The incidence of pin site pain and infection was also reported at 0.5% and 1.2%, respectively.…”

This study aims to evaluate the 2-year post-operative clinical outcomes of patients undergoing total knee arthroplasty (TKA) with computer-assisted surgery (CAS) using the pinless BrainLAB ® VectorVision ® Knee 2.5 Navigation System versus standard CAS. A retrospective case-control study of 200 patients who underwent TKA with CAS from 2008 to 2012 was conducted. Patients in the pinless arm underwent a shorter duration of surgery compared to the standard CAS arm with 72 + 13 min and 83 + 11 min, respectively (p < 0.001), with improvement in Oxford Knee Score from 34 + 8 to 18 + 5 and 34 + 9 to 18 + 5, respectively, without statistically significant differences in clinical outcomes at 2 years.

“…Spencer et al ,27 in a randomised controlled trial of 71 patients with a minimum of 2 years of follow-up, found no significant difference in functional outcome scores between patients managed with computer-assisted navigation and those managed with conventional arthroplasty. Zhang et al ,19 Blakeney et al 20 and Cip et al 22 were all able to demonstrate better alignments in CAS TKA but not any improved clinical outcomes.…”

“…It can be concluded that even experienced surgeons may improve their skill while implanting joint replacement under navigation control. However, the question of the clinical relevance of this improvement is still debated, with conflicting positive [29, 30] or negative [31, 32] impacts of navigation.…”

The goal of this review paper is to retrieve from the existing literature relevant information (1) about the learning curve of the currently existing navigation systems and (2) about the use of navigation system for teaching orthopaedic procedures. All studies reporting on the learning curve of navigation systems support the hypothesis that computer-navigated total knee arthroplasty (TKA) involves only a short learning curve and that beginners can obtain good results from the beginning of their experience, as navigation provides continuous feedback during all phases of the knee replacement surgery and allows for correcting any bone cut errors. Interestingly, there is no comparable research on the learning curve of TKA with standard, manual instrumentation. One might postulate that this learning curve might be longer than with navigation, with potentially a higher rate of outliers. The current literature does support that navigation may be an efficient teaching tool for both experienced orthopaedic surgeons and trainees. Experienced surgeons may improve their skills with conventional techniques and learn new techniques more efficiently and more quickly. Trainees may have a better understanding of the procedure and learn standard techniques with a shorter learning curve. This is probably due to the immediate feedback of navigation systems. A shorter learning curve may be associated with improved clinical and functional results for the patient during this critical period. However, there is no evidence that training with navigation excludes trainees from the need to work in academic environments with experienced teachers. Future techniques in training may include the development of laboratory simulation procedures using navigated feedback.
