Abstract (original English)

Aim: Osteoarthritis (OA) prevalence is increased in ageing and obese populations. This prospective single-arm cohort study aimed to investigate the efficacy of autologous microfragmented adipose tissue treatment of severe knee or shoulder OA. Materials & methods: Participants received an intra-articular microfragmented adipose tissue injection to the affected joint(s). Multiple patient reported outcome measures (PROMS) were recorded from 0 to 52 weeks for 63 consecutive joints. Results: Compared with baseline, there were significant improvements in all PROMS from 2 to 12 weeks and maintained at 52 weeks. Regression analysis revealed an inverse correlation with BMI and change in PROMS for knee joints. Conclusion: Our observed findings suggest this approach represents a safe, effective treatment for moderate-to-severe knee and shoulder OA, although efficacy may be reduced with increasing obesity. Swelling and pain in the joints is common and found more often in older and overweight people. Osteoarthritis causes swelling and pain in joints because of a loss of tough, flexible tissue called cartilage. This study looks to see if injection of fat tissue into knee or shoulder joints can improve symptoms. The fat tissue used was called microfragmented adipose tissue (MFAT). This uses a technique to break down the fat tissue before injection. These cells were from the patient’s own body
