A Regenerative Medicine Potpourri
I have been invited to participate in a Crain’s Chicago Business Orthopedic Roundtable discussion scheduled to appear in Crain’s on 02/24/2020. My focus will be on Orthobiologics and Cellular orthopedics. As readers of this blog are aware, I personally underwent orthobiologic interventions into my hips and knees in December. This past weekend, I trekked and trudged through 8 inches of snow to reach some of my favorite trout creeks in Southwest Wisconsin’s Driftless Area. While the fishing was slow to say the least and my fingers were frozen, my hips and knees did great.
Does Bone Marrow Concentrate really work?
From The Am J Sports Med. 2019 Oct;47(12):2881-2887. doi: 10.1177/0363546519867933. Epub 2019 Aug 21
Equivalent 10-Year Outcomes After Implantation of Autologous Bone Marrow-Derived Mesenchymal Stem Cells Versus Autologous Chondrocyte Implantation for Chondral Defects of the Knee.
The use of bone marrow-derived mesenchymal stem cells (BMSCs) in cartilage repair procedures circumvents some of the limitations of autologous chondrocyte implantation (ACI), but long-term outcomes for this newer procedure are lacking. The authors previously reported comparable outcomes for the 2 procedures at 2-year follow-up.
The purpose was to compare the long-term clinical outcomes of ACI versus BMSCs. It was hypothesized that there would be no significant difference between the groups in terms of patient-reported outcome scores and safety outcomes at 10-year follow-up.
Cohort study; Level of evidence, 2.
Seventy-two patients who underwent either ACI or BMSC implantation-matched in terms of age and lesion site- were followed up to a median of at least 10 years. Patients were assessed with the 36-item Short Form Health Survey (SF-36), the International Knee Documentation Committee knee evaluation form, the Lysholm Knee Score, and the Tegner Activity Scale. In addition, information was obtained regarding any additional surgical procedures as well as safety data, with particular attention to infection and tumor formation.
There was an improvement in all patient-reported outcomes scores apart from the Mental Component Summary of the SF-36 after cartilage repair surgery. There was no significant difference in any of the patient-reported outcomes between cohorts at any time point. Six and 5 patients in the ACI and BMSC groups, respectively, underwent subsequent surgical procedures, including 1 total knee replacement in the BMSC group. None of the patients in either group developed any deep infection or tumor within the follow-up period.
BMSC implantation used for the treatment of chondral defects of the knee appears to result in equivalent clinical outcomes to first-generation ACI at up to 10 years, with no apparent increased tumor formation risk.
An Update about our FDA-Approved Personalized Stem Cell Clinical Trial.
Some changes are taking place in the trial to allow an accelerated recruitment on the one hand; but an overall decrease in the number of subjects who will be allowed to participate. If you are interested, please call about changes in the inclusion criteria and costs: (312) 475 1893
