Causes of pain and loss of function in rotator cuff disease: analysis of 1383 cases
Long head of biceps (LHB) pathology has been traditionally been thought to be a pain generator of rotator cuff disease,6 but once again the majority of studies have focussed on post‐operative outcomes.7 Likewise, labral pathology has been linked to poor function but limited literature is available.9
The New Zealand Rotator Cuff Registry is a multicentre nationwide registry of rotator cuff operations. To date, it is the largest prospective study of rotator cuff repairs, and is the first registry to include both open and arthroscopic repairs.10
This aim of this study was to investigate the relationship of rotator tear characteristics and other shoulder pathology on pain and function in a large cohort of patients presenting for rotator cuff surgery.
