  1. aData are provided as mean ± SD or n (%), unless otherwise noted. Bold indicates P < .05. PD, Parkinson’s Disease; AP, anteroposterior; GFDI, global fatty degeneration index
  2. bTear size was measured arthroscopically with a calibrated probe at the time of surgery and classified according to the rating system of DeOrio and Cofield
  3. cFatty infiltration was graded in accordance with the criteria established by Goutallier et al.
