This systematic review summarizes the latest evidence, on postoperative rehabilitation protocols for patients undergoing ulnar collateral ligament reconstruction (UCLR). Studies published in the English language from the year 2000 to 2019 with a level 1 to 4 grade of evidence and examined rehabilitation protocols following UCLR were eligible for inclusion. A multidatabase search was conducted. Two blinded reviewers screened and graded articles for inclusion and a third independent reviewer resolved any conflicts. Ten of the original 139 studies identified were used for analysis. Surgical techniques as well as rehabilitation protocols varied across studies. Analysis gave strong evidence that a 4-phase postoperative rehabilitation protocol utilizing milestone-based goals is effective in returning athletes back to preinjury levels of activity and sport within 1 year following UCLR.
