The superiority of navigation and robotics in hip arthroplasty: fact or myth?

Computer-assisted surgery represents a relatively novel treatment option in total hip arthroplasty, which has been supported by the technological progress over the latest decades. Navigation and robotics enable increasing the precision of cup positioning, as well as successful biomechanical restoration of leg length and offset. However, the intended target area is still one of debate in literature. Besides the learning curve, the use of navigation and robotics requires additional time and financial expense, which has not yet been addressed in the German healthcare system. This is one reason why computer-assisted surgery has not fully attained everyday routine. The number of comparative studies is limited, but the results are promising. However, if these surrogate measures will end in reduced revision rates or better outcome is unclear. Further prospective studies and register analysis might illuminate the potential benefit of navigation and robotics.

Automated summary

Computer-assisted surgery is a relatively novel treatment option in total hip arthroplasty, supported by technological progress. Navigation and robotics improve precision and biomechanical restoration, but the target area and cost effectiveness are still debated. Further research is needed to evaluate the potential benefits and outcomes of this technology.
