Overview

The Joint Preservation Institute is an orthopaedic practice led by Dr Amir A. Jamali, a board-certified orthopaedic surgeon, with offices in Walnut Creek and Sacramento, California. The name reflects its stated focus: trying to preserve a patient's own joint where possible, using surgical and injection-based techniques, rather than moving straight to joint replacement.

On the surgical side the practice offers hip preservation and hip replacement, knee preservation and knee replacement, and shoulder arthroscopy (keyhole surgery inside the shoulder joint). On the injection side it offers platelet-rich plasma (PRP, made by concentrating platelets from a sample of the patient's own blood), bone marrow aspirate concentrate (BMAC, marrow drawn from the pelvis and spun down before injection), and Lipogems, a commercial system that processes a small sample of the patient's own fat so it can be injected.

The site describes the cells used as coming from the patient's own body, specifically mesenchymal stem cells from bone marrow taken from the iliac crest of the pelvis. It should be noted that the conditions listed extend well beyond orthopaedics into cardiovascular, neuromuscular and autoimmune disease, which is far outside the surgical scope described elsewhere on the site. Ask specifically what the practice actually treats and what evidence supports cell injection for your own diagnosis.
