1. A method of shoulder arthroscopy, comprising:
forming a first portal in a shoulder of a patient to access a subacromial space in the shoulder;
introducing an endoscope through the first portal to visualize the subacromial space;
forming a second portal in the shoulder to access the subacromial space;
introducing a working end of a probe having a longitudinal axis through the second portal into the subacromial space, wherein the working end includes a first element for cutting soft tissue, a second element for applying RF energy to tissue, and a third element for bone cutting or burring;
cutting soft tissue with the first element to access targeted bone, wherein the first element includes a windowed cutting member, and wherein said cutting soft tissue with the first element includes rotating the windowed cutting member in a window of an outer sleeve, the window of the outer sleeve including a single scalloped lateral side, the outer sleeve including a distal end surface that transitions into the single scalloped lateral side with a first barb-like portion for capturing and retaining tissue within said outer sleeve window, wherein the single scalloped lateral side extends in a proximal direction along the outer sleeve from the first barb-like portion to a proximal end of the single scalloped lateral side, the proximal end of the single scalloped lateral side being void of a barb-like portion such that the first barb-like portion is the only barb-like portion positioned along the single scalloped lateral side;
applying radiofrequency (RF) energy to ablate bone surface tissue with the second element; and
burring the targeted bone with the third element to thereby treat the subacromial space.
