Abstract

Introduction: The subacromial balloon is a novel therapeutic device that is used in patients with massive irreparable rotator cuff tears (MIRCTs). The novelty of this device implies that there is still a lot to be known about its mechanism of action and rehabilitation trends. One rehabilitation trend that has been noticed is the “balloon dip”, where a patient exhibits exacerbations in pain and function around 3 months following balloon implantation and after having experienced earlier symptomatic relief post-operative. We discuss the clinical, diagnostic, and therapeutic aspects of the patient’s management while providing additional insight into this prognostic trend. Case Report: In this report, we present the case of a 65-year-old male patient who underwent a subacromial balloon procedure for a MIRCT. During his recovery, the patient exhibited a classic “balloon dip” evident by an exacerbation of pain and function around the 3-month mark. After a notable deterioration in pain and function, the patient was examined, reassured, and educated on the importance of adhering to physical therapy. He was able to successfully recover and showed gradual improvement in pain and function along the course of the year. Conclusion: The “balloon dip” is a rehabilitation pattern that occurs 3–6 months following subacromial balloon spacer implantation. In the majority of cases, careful clinical assessment, watchful monitoring, and education on the importance of following up with physical therapy are sufficient to overcome the dip.
