# EVALUATION OF TENDON HEALING AFTER ARTHROSCOPIC REPAIR OF ISOLATED SUPRASPINATUS TEARS

## TL;DR

This study evaluated how well supraspinatus tendons heal after arthroscopic repair, finding an 81.7% healing rate with reliable evaluations.

## Contribution

The study provides a reliable evaluation of healing rates and observer agreement in arthroscopic supraspinatus repair.

## Key findings

- The mean healing rate for supraspinatus tendon repair was 81.7%.
- Intra-observer agreement was excellent, and inter-observer agreement was good.
- Most patients showed healing grades I to III in the Sugaya classification.

## Abstract

To evaluate the healing of supraspinatus tendon lesions after arthroscopic repair, with analysis of intra- and inter-observer agreement by two experienced evaluators for the same lesions.

A study was conducted with patients evaluated in the postoperative period of arthroscopic surgery to repair isolated supraspinatus tendon ruptures, with a minimum follow-up of one year. Tendon healing was evaluated using magnetic resonance imaging by two independent evaluators at two time points, with a seven-day interval between them. Categorical data were presented in absolute and relative frequencies, and mixed linear regression models were used to analyze intra- and inter-observer agreement, with a probability of rejecting the null hypothesis of 5%.

Twenty-three patients (26 shoulders) were evaluated, with a mean age of 61.5 years. At both evaluation times, most patients presented a healing grade between I and III in the Sugaya classification for both observers. The interobserver agreement was good, and the intraobserver agreement was excellent.

The mean tendon healing rate for arthroscopic repair of isolated supraspinatus ruptures was 81.7%. Intra-observer agreement ratings were considered excellent, while inter-observer agreement was good, demonstrating reliability in the evaluations performed.
