Shoulder joint replacement arthroplasty - what outcomes do patients care about?

Surgeons evaluate the outcome of shoulder arthroplasty in terms of a single numerical score using metrics with initials such as PROMIS, ASES, CMS, SMS, PASS, MCID, SANE, UCLA, SCB, and VAS which do not have meaning to patients. 

Patients evaluate the outcome of shoulder arthroplasty in terms of their postoperative shoulder comfort and function, i.e. what are they able to do after the procedure. 

There is now a growing trend to evaluate specific shoulder functions after shoulder arthroplasty, so that data on specific activities performable after surgery can be shared with prospective patients.

Functional aspirations obviously differ among patients. Some want to be able to return to their work, others want to be able to throw a ball with their children or grandchildren, and others simply  want to regain their ability to sleep comfortably. See, for example, Improvement in Sleep Disturbance Following Anatomic and Reverse Shoulder Arthroplasty

Recognizing that different individual functions are not of equal value to different patients, the Simple Shoulder Test evaluates the outcomes for twelve different functions previously identified as being of importance to patients having shoulder arthroplasty.



Below are three papers that report patients' ability to perform these 12 individual functions before and after different types of shoulder arthroplasty.






The authors of What Activities Do Patients Hope to Perform Following Reverse Shoulder Arthroplasty But Are Unable To? Looking Beyond Patient-Reported Outcome Measures used a somewhat different approach in their survey of 142 patients at least two years (average 4.3 years) after reverse total shoulder arthroplasty. A large majority reported little-to-no difficulty with driving a car (90%), managing toileting (84%), putting on a seatbelt (82%), and washing hair (81%). However only 59% percent reported being able to reach shelves at home with minimal difficulty. Furthermore, when asked in a free text questionnaire which activities they wanted to perform, but felt unable to, patients most commonly self-identified tennis (15%), swimming (11%), throwing a ball (11%), golf (10%), and lifting weights or exercising the arm (10%). 

Comment: Patients considering shoulder arthroplasty want to know what their function is likely to be after shoulder joint replacement. Surgeons may wish to inform prospective patients regarding the functions patients can perform after the different types of shoulder arthroplasty used in their practice.
