^aRange 0 – 100. Higher scores indicate less pain and other symptoms and better function

^bAge at the time of operative fixation of the loose body

^cRange 0 – 16. Higher scores indicated higher levels of activity

^dThis patient is only 1.8 years post-op at the time of publication

^eMean time to follow-up for those available for follow-up at greater than 2 years post-operative

^fStatistically significant (p < 0.05) when compared with age-matched controls
