New Study Shows Same Day Stem Cells with Knee Surgery better than Knee Surgery Alone

surgery plus stem cells is better

A new study out this week shows that a similar type of stem cell isolation as that used in Regenexx-SD (without the superplatlet mix that helps stem cell growth), when added to knee debridement surgery improved pain and function over the knee surgery alone. The study compared 50 patients who were divided into two groups and assigned to receive knee debridement surgery for osteoarthritis or the knee surgery plus the same day stem cells harvested from a simple bone marrow aspirate. Given the good results we’ve seen with knee stem cell injections, this result isn’t surprising. In addition, since knee debridement surgery has been shown to be no better than a placebo surgery, we’d recommend that in most patients the surgery part isn’t needed-these patients would just need the knee stem cell injection without the sugery. These results are in contrast to those obtained in a recent study where platelet rich plasma was added to arthroscopic knee surgery. In that study, no difference was found between the PRP knees and the knees treated with surgery alone. Again, this isn’t too surprising, as PRP works by ramping up growth. In most severely arthritic knees, there isn’t much left to grow. On the stem cell front, based on experience and the data already presented about stem cells and knee arthritis at conferences and submitted for publication by our group, we expect to see more of these positive knee stem cell studies in the next few years (including ours). As an example, another recent study showed that stem cells plus micro fracture knee surgery was better than micro fracture alone. Finally an earlier study from last year demonstrated that the use of bone marrow stem cells instead of chondrocytes in ACI knee surgery (autologous chondrocyte implantation where cartilage cells are sewn into a hole in the knee cartilage), resulted in overall better results with less complications. The upshot? So far the real world clinical data is showing that surgery plus stem cells is better than surgery alone.
