The use of mesenchymal stem cells from bone marrow concentrate (BMC) has become an increasingly popular option as an alternative to total joint replacement. Although there is evidence to support the use of BMC injections to improve quality of life for patients with knee osteoarthritis (OA), there is limited evidence to support its use in patients with hip OA. This case series provides the short-term outcomes of 4 hip OA patients who each underwent 4 BMC injections. On average, the last follow-up was administered 3.5 months after the first injection. The results show that patients experienced decreased resting and active pain compared with baseline and mean 72.4% total overall improvement. Patients also reported less difficulty in performing daily activities following the procedure. These encouraging results warrant further research to better understand the effects of BMC injections on hip OA.
