Cutting edge protocols:  Modern state of the art Total Knee Replacement means less traumatic techniques to minimize pain, swelling, and bleeding for a quicker recovery and faster return back to a normal, active life.  In 2014 some healthy, carefully selected patients are able to be discharged to home directly from the recovery room after Less Traumatic TKR.  In 2015 our top surgical team of RN’s, Surgical Tech’s, and Periop Nurses have moved to SurgCenterGreaterPHX (opens February, 2015), a same day surgery center. The center will be our preferred surgical location, rather than a traditional inpatient hospital.

Outpatient Total Knee replacement has advantages.  Think no hospital room charges, no exorbitant hospital medication and physical therapy costs.  Think Less Overtreatment because there will be fewer blood tests and fewer doctor/nurse encounters.  Less testing and less overtreatment avoids unwanted complications from unnecessary medical care.  We can not say for sure infections rates are lower when patients avoid hospital stays but we think it to be true: the germs in your home are your friends.  They know you, they live with you everyday and they do not often harm you.  The germs in the hospital are germs you have never met.  They do not know you.  They are often nasty germs that are can harm you.

For patient comfort, continuity of care and peace of mind we offer our patients the option to have home RN and PT visits for the first several days at home after Same Day Total Joint Replacement.

Less Traumatic Total Knee Replacement is the culmination of years of innovative improvements in all facets of surgical strategies and techniques, with the ultimate goal to attain the best possible outcome for every patient. Let our team show you how Less Traumatic TKR can improve your life.

total-knee-replacement-2Knee Arthritis Treatment Options

Advanced arthritis of the knee symptoms (pain, stiffness, limited motion, decreased walking and standing tolerance) often times intensify to the point of interfering with daily activities and causing intolerable pain during some or all activities. For these people, surgical intervention using knee joint replacement implants often times returns patients back into their normal life style with markedly diminished or no knee pain.

Non Surgical “Step Treatment” Alternatives to Total Knee Replacement

Self directed treatments can be helpful in cases of mild to moderate knee osteoarthritis.  These measures includes optimizing body weight, daily aerobic low impact exercise, activity modification/rest, ice and OTC pills such as ibuprofen, naproxen, or acetaminophen. Physician directed treatments include physical therapy, prescription anti inflammatory NSAID like Celebrex or Mobic, Cortisone injections, Visco gel injections, arthritis unloader bracing, acupuncture, and if indicated for meniscal tear or loose body – knee arthroscopy.

Total or Makoplasty Partial Replacement Replacement – How to decide which is best ?

Total Knee replacement is done when 2 or 3 of the knee compartments are completely worn out.  These patients typically limp, have crooked legs (varus- bow leg or valgus- knock knee) and limited knee motion. Partial or Unicompartmental Knee replacement is done robotically using the Makoplasty technique when only one compartment is diseased or injured.

Total Knee Implants Systems:

For 2015 – Choose Your Implant for Same Day Knee Replacement at SurgCenter of GreaterPHX.   To improve patient satisfaction and to emphasize the distinction of Total Knee Replacement in the Ambulatory Surgery Center Dr. Tarlow will consult with the patient and together we will choose which implant the patient desires for their knee (applies to outpatient Total Knee Replacement at SurgCenter GreaterPHX only).  In addition to the implants listed below, choose from one of the major joint replacement brands including Depuy, Smith and NephewStryker, and Zimmer.

The key for a successful Less Traumatic Total Knee Replacement is precise implantation by a skilled and experienced surgeon.  Doctor Tarlow’s system of choice is the Ortho Development Balanced Knee System for primary TKR (first time surgery).  The Ortho Development Balanced Knee System is the revision system preferred by Dr. Tarlow.


Ortho Development Balanced Knee Implant

Ortho Development Balanced Knee System

The Ortho Development knee implant is US designed by Engineers and Orthopedic Surgeons.   Components are manufactured in Utah, Massachusetts, Ohio.  The materials are sourced in the US.  The original design has been modified three times since the introduction of this implant in 1998, incorporating engineering refinements that are associated with improved patient knee function. Design highlights include Vitamin E antioxidant polyethylene tibia and patella components,  patented tibial insert locking mechanism to limit micromotion, anatomic low profile femoral components with narrow sized options for precise fit, tibial inserts that are available in 1mm increments in the most popular thicknesses to give the surgeon the ability to micro tune the stability of the knee.  16 years on the market and no mechanical failures or recalls with the Balanced Knee System.

Patient Health Optimization

Patient health optimization is key to a good surgical outcome. Patients should get 30 minutes of low impact, aerobic exercise (break a sweat) for at least 6 weeks prior to Knee Replacement surgery, even if it causes knee pain. Patients should have a reasonable Body Mass Index (lower than 35 is good, 40 may be acceptable). Successful weight loss patients use exercise and food portion control (using Food Diary). We can refer you to a physician to help with weight loss. Smokers should refrain from smoking for 6 weeks prior to surgery and not smoke for the 2 months after their joint replacement. Help to stop smoking is available from ASHLINE. Diabetics, type 1 and 2, need to have Hemoglobin A1C less than 7 around the time of surgery and on the day of surgery blood sugar should be less than 150. Much higher risks for a bad outcome are associated with obesity, smoking and diabetes, with complications occurring in 25% of patients with all three of these risk factors. Morbid obese patients are 25 times more likely to suffer a post-operative infection. Failure Rates (all causes – infection, reported pain, instability, loosening, re-operation) are double in this patient population. Complications such as wound bleeding, blood clots and Surgical Site Infections (SSI) usually result in repeat hospital admissions, repeat surgery, prolonged recovery and unfavorable outcomes. The goal is to have a positive experience with Knee Replacement Surgery.  The best course of action is to optimize your health to minimize complications.

Less Traumatic Total Knee Replacement

knee-replacementWhat I see in my day-to-day practice is that hospital length of stay and return to work and recreational activities are excellent for Less Traumatic Total Knee Replacement patients. In 2014 healthy, motivated people can go home the same day as the Less Traumatic Total Knee Replacement. These good outcomes are from advances in surgical technique including using the smallest workable knee incisions with careful handling of knee tissue, improved implant design, multimodal pain management, thirteen step infection avoidance treatments, pharmacologic bleeding control, and improved rehabilitation methods (cold therapy, compression, early activity). Standardized surgical teams improve surgical processes and maximize best practices and minimize complications. At this writing (12/2014) the use of computer navigation and limited incision techniques for total knee replacement is uncommon (6% of total joint surgeons worldwide). While this issue was at the forefront of Orthopedic Debate in the mid 2000’s, it is rarely discussed at National Orthopedic Meetings today. The matter has been resolved. There is no patient benefit with MIS – CAS technique for Total Knee Replacement.  Now, Less Traumatic Total Knee Replacement patients routinely recover with less pain and have a faster return to normal function due to multimodal pain management, improved traditional surgical techniques, and rapid rehabilitation protocols.

I will continue to evolve surgical techniques and incorporate new technologies into the practice of orthopedic surgery to improve patient experience and patient outcomes.

The Current State of Affairs in Total Knee Replacement Surgery

Less Traumatic Total Knee Replacement surgery uses standard instruments and does not require the use of computer navigation. Improvements over the last decade in traditional surgery techniques, multimodal pain management, infection prevention and rapid rehabilitation protocols produce the best patient recovery paths. Our patients do great!

Typical Recovery: Hospitalization 0-2 nights. Walker for 5-10 days. Driving within 2-4 weeks. Return to work in 1-3 months. Results vary depending on individual’s physical condition, other constitutional characteristics. Many patients take a year to reach a completely healed state.

Typical Risks include infections, blood clots, wound bleeding and knee stiffness. Antibiotics are used in the peri operative period to lower infection risk. Aspirin, Sequential Compression Devices and early mobilization are used to lower risk of blood clots. Aggressive, early Physical Therapy for 6-8 weeks is used to maximize range of motion and function.

Billing and Coding: The CPT billing code for TKR is 27447, for unicompartmental knee replacement 27446 and for patellofemoral arthroplasty 27438. These codes are useful to patients when discussing cost with insurance companies or surgeons. Surgeon fee varies between physicians but is typically several thousand dollars (Dr. Tarlow fees). Charges typically associated with TKR(CPT code 27447) include surgeon fee ($4000-4500), surgical assistant fee ($300), anesthesiologist fee ($850-900), hospital fee (1/3 less at SurgCenterGreaterPHX vs. inpatient hospital) and physical therapy fee.

Guidelines for Antibiotics After Total Knee Replacement:

From AAOS Clinical Practice Guide
For routine dental prophylaxis, one dose Amoxicillin 2 grams orally one hour prior to dental work is standard.

Use Clindamyacin 600 mg if PCN allergic.

In 2012 this recommendation was changed once again: Current recommendation is use only in the first year after joint replacement if healthy patient without dental infection.  Susceptible patients (diabetes, HIV, Rheumatoid on immunosuppresive meds, Cancer patients immunocompromised – to name a few) should always use prophylactic antibiotics for Dental work.
