Great doctor, knowledgeable and very much care for patients. Thanks dr for your help.
I was diagnosed with a frozen shoulder after rotator cuff surgery that utilized a Regeneten Bioinductive Implant. After 5 months of PT my range of motion had not improved much. At that point Dr. Gruner did a capsular distention procedure on my shoulder. After the procedure was done there was a rapid and significant improvement across all planes of range of motion. I am very very pleased with the results of the capsular distention procedure performed by Dr. Gruner.
he's good and listening to my questions. I have no complaint.
Good manner Professional best explanation as to my circumstances and possible remedies
Very knowledgeable; reviewed previous diagnosis from other doctors and determined I need to explore a different path to recovery. Provided next steps to get to the bottom of my multi year issue which has not been resolved by numerous medical providers. Ordered MRI and PT sessions; provided reading materials for strength training, and recommended support cushion to use in the meantime to alleviate symptoms. I’m very hopeful I’ll see results finally under this doctor’s guidance!!
Professional Caring and all around great experience
God bless him, he helped me so much So much with my severe pain even do, I didn't have an appointment the whole stuff treat me really good, that for a moment totally forgot how much pain I had Thank you souch to Othobethesda team and Doctor Marc Gruner
Very knowledgeable and helpful!
Dr Gruner is one of the most sympathetic and caring doctors I have ever visited. He takes his time with patients, goes over options (always from conservative up to drastic) and is not one of those guys who shrugs and says “it’s up to you” when you ask what he would do. He is also very up to date on cutting edge procedures.
Everything about my visit went v well - all the staff were friendly & informative. Dr G, as usual, was calm, clear - and… the shot he put into my hip made the pain disappear!
