This article tells me that at the time of it’s writing, there was not a lot of high level evidence behind these protocols (at least not full text available in English). It highlights the fact that whether RTSA or anatomical TSA there is a lot of variability behind protocols. It highlights the common concern for subscapularis tendon integrity, as well as potential stress fractures. Essentially, take them with a grain of salt, consider the anatomy involved, review the op report if available and consider the involved structures and the stages of healing when progressing your patient.
