The influence of computer navigation on trainee learning in hip resurfacing arthroplasty.

Computer navigation in arthroplasty surgery is a form of concurrent augmented feedback. Motor learning theory suggests such feedback may be detrimental to learning as a result of the learner either developing a dependence on the additional feedback or being distracted from using intrinsic feedback. To determine whether computer navigation influences the learning curve of novices performing hip resurfacing arthroplasty, a systematic review and critical appraisal of the current English-language literature on the topic was conducted. There is some evidence that use of navigation by trainees facilitates more accurate placement of arthroplasty components as compared to conventional instrumentation. However, there is no evidence that training with computer navigation impairs performance in retention or transfer tests. Thus, although the published literature has significant limitations, there is no evidence that supports concerns regarding the impact of computer navigation on the learning curve of arthroplasty trainees.
