The level of evidence is indicated at the end of each review when it is known. Particular attention should be paid to the Level-I and Level-II studies as they represent randomized controlled studies. However, study design and analysis influences the quality of these studies. Additional Level-III and Level-IV studies representing important topics in shoulder and elbow surgery are also included in the review.
