Yes. The team spins the exudates during surgery and pours it back into the wound at closure. Since this was part of a grant study, over 5 years ago, your Surgeon needs to talk to Dr. Junik. I am well known by Dr. Junik, so refer to William D. Monlux the Physical Therapist from Taos,N M and that will jog his memory. He can tell your Physician about the data on success of the procedure and the particulars on the preparation and centrifuge of the exudates. I will give you a lot of information. He moved his office. New Location: 2100 Lousiana Blv. Suite 410, Alburquerque, NM 87110. Main Office-1-800-339-5161 (505-724-4300) After Hr: 505-724-4300-WorkLink Wed.

I have -personally had excellent results. I asked very few questions because I was knowlegeable. I had only One follow up visit because I followed up with home health and out patient Physical Therapy. Target a year. Those that go home and do nothing have less results than I did. So, when you read comments on Dr. Junik, most are good but some are poor. He has a number especially for people who ask questions after surgery. Be aware. This is one of the most tender surgerys you can have for the first 2 days. After that, the daily P.T.,0.T. and personal nursing care shines through;. I have virtually no pain any time. I have full ranges of motion. I have paper thin scars.Do what your Physicians says. Do not do Sucker deep bend on you T-K knees and extreme movements in yoga, or other sports. Use a good castered walker with a seat. Stand at your sink and put the walker behind you. Do squats hanging onto the sink and squat down until you touch your walker seat. Do this the rest of your life. Case in point. Something like a piece of anything falls on the floor. Lock your walker or stabilize by hanging onto something. Keep your head up to keep from falling forward. DO MOT KEEP YOUR LEGS LOCKED AND REACH FOR THE FLOOR..The sink training is enough to allow you to reach the floor, The straight leg reach is poor mechanics and may induce back problems. The daily semi-squats will keep your quadriceps at good-good +.. Standing heel and toe 2 sets of 10 in your walker or at the wall should be done daily. Sitting quads with 10# or more ,if in good shape, helps. Walk a block each day. Up and down your hall if necessary. Remember, you eat to survive. You exercise daily to be actively..These two things are necessary. I know you will be your own care giver after one year. I am 90 yrs old with beautiful total knees. Good Luck! Contact me at this place at ant time. If I am still alive, I will answer you. Ha!
