Key result
The authors express concern regarding the high level of emphasis placed on repair of the rotator interval as being critical to success in the arthroscopic treatment of posterior shoulder instability.
Questions emphasis on rotator interval repair in arthroscopic posterior instability; hypothesis-generating and should not yet change practice.
We read with interest the article “Arthroscopic Management of Posterior Instability: Evolution of Technique and Results” by Savoie et al.1 in the April 2008 issue of the Journal. The authors have had excellent results in 136 patients treated arthroscopically for posterior shoulder instability. The authors should be commended for describing the evolution of their repair technique and recognition of the pathology with a posterior instability lesion. However, we are concerned with the high level of emphasis that the authors placed on repair of the rotator interval as being critical to success in their patient population.

Provencher et al. (2008) conducted a letter in posterior shoulder instability (n=136). Repair of the rotator interval was evaluated. The authors express concern regarding the high level of emphasis placed on repair of the rotator interval as being critical to success in the arthroscopic treatment of posterior shoulder instability.
