Brief summary: Treatment of isolated osteoarthritis of the glenohumeral joint at the initial stages involves the use of numerous conservative or arthroscopic treatments with uncertain results and, upon their failure, the current solution for the resolution of symptoms is shoulder arthroplasty, an effective procedure but with significant costs and rates of morbidity, especially in young patients. Since the use of intra-articular injections of mesenchymal cells obtained from the bone marrow has proved effective in the treatment of gonarthrosis, our goal is to evaluate the effectiveness of the same therapy in the treatment of glenohumeral arthritis isolated.

Detailed description: Glenohumeral arthritis is one of the main reasons for persistent shoulder pain and reduced movement (range of motion, ROM) as it can compromise the work activity and also the normal daily activities, leading to the development of depressive syndromes. The final treatment is shoulder arthroplasty, which is effective but is associated with significant costs and morbidity rates. In addition, arthro-prosthesis is avoided in young patients due to longevity concerns and is not indicated in the early stages of arthritis. Currently, conservative treatments for patients with mild or moderate glenohumeral arthritis include non-steroidal anti-inflammatory drugs (NSAIDs), corticosteroid injections, with low efficacy and a significant adverse effect profile, hyaluronic acid infiltrations, with good efficacy in initial treatment, and infiltrations of platelet-Rich Plasma (PRP), which have shown beneficial effects in knee arthritis. However, evidence for the glenohumeral joint are limited. In cases not responsive to conservative therapy, and especially in young patients, a valid alternative to the prosthesis is the arthroscopic treatment, with good results in the short term, but with relatively high failure rates that increase over time. Other types of nonprosthetic surgical treatment for chondral-humeral defects have low scientific evidence, with variable and uncertain results. In recent years, mesenchymal stem cells (MSC), derived from bone marrow or adipose tissue, due to the ability to differentiate into chondrogenic line cells, have emerged as cells with great therapeutic potential in patients with degenerative joint disorders. Since the knee joint is the most susceptible to pathology because of its mechanical load, most studies based on stem cell therapy regard the knee joint, reporting promising results in treatment in the treatment of early stages of arthritis. As regards the glenohumeral joint, since the most frequent pathology affects the tendons of the rotator cuff, almost all studies investigate the effect of MSC in the treatment of rotator cuff disorders with or without associated surgical repair techniques. Only a prospective study analyzed the effect of intra-articular MSC injection derived from bone marrow in 34 patients with isolated glenohumeral arthritis, reporting a significant decrease in pain and an improvement in shoulder function measured by the Disabilities of the Arm, Shoulder and Hand (DASH) scale at about 1 year, although study quality is very low. Since the use of intra-articular injections of mesenchymal cells obtained from the bone marrow has proved effective in the treatment of gonarthrosis, our study proposes to evaluate the long-term efficacy of this type of therapy in the treatment of the isolated glenohumeral arthritis.
