Clinically-driven approach to improve arthroscopic techniques.

In this paper, a clinically-driven approach is introduced as the starting point for the improvement of arthroscopic techniques. The approach was divided into two phases. Phase 1 consisted of a combination of observations and discussions that resulted in the definition of clinically-relevant research topics. Phase 2 consisted of an interview which aimed at analysis of the general opinion on arthroscopy, and which assigned a priority ranking to the topics. Six research topics were defined. Based on the information collected, the conclusion is that the surgeons are satisfied with current arthroscopic techniques. A majority gives priority to the optimization of cartilage treatment and to the design of a steerable arthroscopic cutter. A minority gives priority to the expansion of arthroscopic techniques. The two-phase approach was fruitful in terms of establishing clinical problem areas, and of involving surgeons in the technical improvement of arthroscopic techniques.
