The incidence of arthroscopic shoulder surgery has increased significantly over the last two decades and is predicted to rise in the next 30 years. This has also led to an increase in patients who are unhappy with the results of their surgery, whether its pain or recurrence of instability. Diagnosing the cause of pain, instability, and recurrent symptoms after soft tissue shoulder surgery is complex, and it involves thorough history and clinical examination along with appropriate radiological imaging. The interpretation of the postoperative scans in such patients is affected by the scarring, metallic artifacts, fluid, and many signs which are pathological in a non-operated shoulder but can be seen as a routine postoperative finding. The clinician should be aware of all this before choosing the ideal investigation. Plain radiographs are used as the first line of investigation in most centers; however, its utility is limited to identifying osseous abnormalities and metal implants. Magnetic resonance imaging (MRI) is the investigation of choice due to its ability to produce very high soft tissue contrast. Most complications after soft tissue surgeries can be detected in MRI scans. However, MRI scan’s utility is limited in the presence of metallic implants. Ultrasonography can be a good alternative in such cases, and various studies have shown that it is as reliable as an MRI scan to detect re-tears of rotator cuff. They have the added advantage of allowing dynamic assessment and can also be used as a guide for therapeutic interventions. However, it is not useful to evaluate labral tears. Computed tomography (CT) scan has a very limited role after soft tissue surgeries and is used only if MRI is contraindicated due to metal artifact interference. Positron emission tomography (PET) and single photon emission CT (SPECT) have a limited role in the management of soft tissue shoulder complications.
