Demetrius "Mighty Mouse" Johnson had surgery on his right shoulder on March 7. He apparently underwent a labral debridement procedure. He is quoted as saying "When the doctor got in there, he saw my shoulder was stable, which is the most important thing."
Most important, indeed. As I noted on a previous post about Johnson’s shoulder injury, one of the primary functions of the labrum is to help stabilize the shoulder joint. It does this by forming a suction seal between the glenoid and the head of the shoulder bone (the humerus).
A tear to the labrum can disrupt this stabilizing force for the shoulder joint, possibly leading to a mild degree of instability. The fact that he had a labral debridement tells me that the labrum was probably not detatched from the underlying bone. This is good, and will likely lead to a faster recovery. This quick recovery also means that the surgery was probably done arthroscopically, rather than with an open incision. (I discuss his surgery in a bit more detail on the MMA Injury blog.)
Johnson is currently attending rehab twice weekly and may return to training in six weeks. He has been surprisingly open about his recovery, posting many pictures of his rehab on his Twitter feed. The fact that his shoulder is stable is obviously very important. Labral tears are often associated with instability of the shoulder, which usually necessitates a much longer recovery time, even for elite athletes. A stable shoulder means that Mighty Mouse should regain power and coordinated movement with the shoulder fairly rapidly.
