Dr Greenbaum is truly elite. A world-class surgeon PLUS a caring, thoughtful bedside manner. (And a super cool guy too!)I have the "blessing" of bad knees - combination of genetics and wear and tear (basketball, mountain biking, golf, college mosh pits). This all resulted in meniscus tears and some arthritis that is slightly more advanced than my age of 45.I had another, well-known physician perform knee surgery about 7 years ago with mixed results. Since then, Dr Greenbaum has performed surgery on both knees. Each surgery involved trimming/repairing the meniscus and then injecting stem cells. I am 9 days out from my most recent surgery. I had ZERO pain and required ZERO meds - not even a Tylenol! I could walk (but see paragraph below) as soon as I woke up from surgery. My knee has almost no swelling. Friends, family and coworkers are amazed by the ease of the procedure, my mobility and how good knee looks. (Two tiny incisions.)My advice is to follow Dr Greenbaum's post-surgery instructions to a tee:- leaving the surgery center, I used crutches to get back into the house.-for the first 3 days, I did NOTHING except R.I.C.E. He just wanted the knee to have time to rest and calm down.- by day 4, I was starting PT and home exercises but at a very measured pace. Just getting the joint moving, keeping an eye on swelling, etc.- even at day 9, I'm continuing to ice and elevate and doing PT, but not rushing things. Dr Greenbaum's office is conveniently located and the billing arrangement with the surgery center was really smooth (bundled everything into one charge.) His staff are very friendly, knowledgeable and efficient. In closing, I'm so grateful for the care that Dr Greenbaum has provided. Two weeks ago, I was limping so badly that finishing a round of golf (with a cart) was difficult. Now, I'll likely be back to full activity within 6-10 weeks. Thanks Doc!
