How patient-reported outcomes help define recovery over time

When patients ask whether shoulder surgery is successful, they are usually asking something deeper: “Will I get back to living the way I want to?”

Success is rarely just about the surgery itself. It’s about what comes after—how quickly pain improves, whether daily activities feel easier again, and if the shoulder holds up over time. At Sano, we pay close attention to those questions by tracking patient-reported outcomes (PROs)—standardized measures that capture how patients feel and function throughout recovery. These tools allow us to measure what matters most to patients, not just what looks good on an exam or imaging study.

Understanding the Measures: ASES and SANE

Two of the most widely used PROs in shoulder care are:

  • ASES (American Shoulder and Elbow Surgeons score): A validated measure assessing pain and function during everyday activities.
  • SANE (Single Assessment Numeric Evaluation): A simple but powerful question asking patients to rate how their shoulder feels overall on a scale from 0–100.

A simple but powerful question asking patients to rate how their shoulder feels overall on a scale from 0–100. Both are used nationally and allow us to compare outcomes over time and against broad benchmark data.

Strong Recovery Early—and Staying Strong

For patients undergoing labral repair—a common shoulder procedure for instability and activity-related injuries—we reviewed outcomes across multiple time points and compared them to national registry averages. What stood out was not just one moment of improvement, but a pattern.
  • At 3 months after surgery, Sano patients reported better shoulder function and confidence than the national average.
This early phase is when patients are starting to resume daily activities, progressing in therapy, and building trust in their recovery. Feeling ahead of schedule at this point can be incredibly meaningful.
At 2 years after surgery, the difference became even more compelling.
  • On average, Sano patients reported shoulder function scores more than 9 points higher than global benchmarks on the ASES scale, with continued advantages on the SANE score as well. 
In other words: patients weren’t just recovering faster—they were doing better long term.

Why This Matters for Active Lives

These outcomes matter for anyone who depends on their shoulder—whether that’s parenting, working, lifting, training, or returning to recreational sports. Sustained improvements at two years suggest not only a successful surgery, but a recovery process that supports durability and lasting confidence in movement.

PROs also help highlight something patients intuitively understand: healing doesn’t stop when physical therapy ends. The goal is not just to “get back,” but to stay back—without persistent pain or hesitation.

Turning Data Into Better Care

Collecting and reviewing outcome data allows us to continually ask hard questions:

  • Are patients improving when they expect to?
  • Are the results lasting?
  • Where can we do better?

“Quality data keeps us honest. When we track outcomes that patients actually feel in their daily lives, it helps us refine how we operate, communicate, and care for people long after surgery.”

This commitment to outcomes transparency helps us refine surgical techniques, improve rehabilitation coordination, and—most importantly—build trust with patients navigating recovery.

The Bottom Line
Shoulder surgery success is not defined by a single moment. It’s defined by meaningful improvement over time—less pain, more confidence, and a return to the activities that make life whole. By consistently measuring and learning from patient-reported outcomes, we stay focused on what truly matters: how patients feel, function, and thrive long after treatment.
