Abstract (original English)

Tennis elbow, also commonly known as lateral epicondylitis or common extensor tendinosis, is a common musculoskeletal injury in the adult population. Currently, the standard treatment regimen prescribed for this injury involves a combination of rest, physical therapy, bracing and anti-inflammatory medications. If refractory to these conservative measures, platelet-rich plasma has been shown effective. However, in the case of full thickness tears, surgery has remained the only treatment option until now. We present a case report of a 56-year-old man with a diagnosis of a left large full thickness tear and rupture with retraction of his common extensor tendon (CET) following a corticosteroid injection. The patient was treated with microfragmented adipose transfer. He was re-evaluated around 7 weeks and again at 15 weeks post-treatment and demonstrated ultrasound evidence of complete bridging and remodeling of his prior full thickness CET tear and resolution of retraction. This case presents a promising option for patients with full thickness CET tears who would like to refrain from or are unable to have surgery. Further research and possible randomized controlled trials are needed to further assess the full efficacy of microfragmented adipose transfer in the treatment of full thickness CET tears. Adipose cells from a patient’s own body fat are one of the best sources of mesenchym
