Long-term Follow-up of Extensive Peri-anchor (Poly-L/D-lactic Acid) Cyst Formation after Arthroscopic Rotator Cuff Repair: A Case Report

Abstract

Suture anchors are commonly used in shoulder surgeries, especially for rotator cuff tears. Peri-anchor cyst formation, however, is sometimes detected on follow-up radiologic image after surgery. The purpose of this report is to discuss the case of a patient who presented with regression of extensive peri-anchor cyst on postoperative 4-year follow-up magnetic resonance imaging and had good clinical outcome despite peri-anchor cyst formation after arthroscopic rotator cuff repair.

Physical Therapy Following Arthroscopic Rotator Cuff Repair with Graft Augmentation: A Case Report with Magnetic Resonance Imaging

“…Considering that the reported minimal important difference (MCID) of pain intensity was 1.1 to 2.17 points [9,26], it was found that the reduced result in this study was a clinically significant result. In shoulder ROM, even compared with other case report studies [27], the increase in baselines appears to quite large. Considering that the reported MCID of SST was 2 points in the shoulder function [28], a reduction of 4 points in follow-up compared to baseline is a clinically meaningful result.…”

Metastasis of renal cell carcinoma around suture anchor implants

“…In addition, a hematoma formed during RCR could be a hotbed for cancer cell seeding [9]. Furthermore, the suture anchor implant is a foreign body inside a bone, which can cause a foreign body reaction, such as activation of macrophages, giant cells, and leukocytes [10]. This foreign body reaction can facilitate the growth of blood-borne tumors, as suggested by Murphy et al [5] However, these explanations for increased susceptibility to metastasis around implants are only hypotheses and are not fully understood; thus, they warrant further study.…”
