Objective:
To confirm the feasibility of laser assisted technology in an office based rheumatology practice and to compare selected outcome variables with those of conventional arthroscopic cutting tools.
Methods:
A prospective analysis of 70 office based arthroscopies on 70 patients with knee arthritis over an 8 month period. All patients met specific criteria for office based arthroscopy. Thirty-six patients had interventions with conventional cutting tools and 34 patients had interventions with a 40 watt holmium YAG laser. Variables assessed included procedure time, length of recuperative period, and postprocedural pain.
Results:
Laser assisted arthroscopy was performed in 34 cases without side effects or complications. Patients who received laser treatment had a shorter recuperative period, less postprocedural pain, and fewer hemarthroses than patients treated with conventional methods.
Conclusion:
While recognizing the shortcomings and possible complications associated with laser surgery, we conclude that laser use in an office setting is not only feasible but may in the future be an excellent method for office based arthroscopic treatment of the arthritic knee.
