# Comparison of Subacromial Bursitis on the Shoulder of the Same Individual After Superior Capsule Reconstruction Using Allograft and Rotator Cuff Tear: A Case Report

## TL;DR

This case report compares shoulder conditions before and after a surgical procedure using an allograft to treat a rotator cuff tear.

## Contribution

The study provides a unique pathological comparison of the same individual's shoulder before and after allograft-based superior capsular reconstruction.

## Key findings

- Allograft revascularization was confirmed two years after surgery.
- The allograft was found to be safe and engrafted successfully after superior capsular reconstruction.
- Pathological differences were observed between the shoulder with and without the allograft.

## Abstract

This paper reports a pathological comparison between the synovium of the shoulder with rotator cuff tears (RCTs) with or without an allograft in the same patient and assesses allograft remodeling after superior capsular reconstruction (SCR). A 49-year-old man underwent SCR with a fascia lata allograft for irreparable RCTs. Two years postoperatively, the patient underwent arthroscopic rotator cuff repair for left RCTs and arthroscopic debridement to alleviate right shoulder pain. Additionally, revascularization was confirmed in the allograft of the fascia lata. In conclusion, allografts are considered highly safe and expected to be engrafted after SCR.
