We’re launching a new patient portal!

Joint Replacement

It’s easy to take knees and hips for granted, but stiffness and pain can sideline you from your favorite activities or everyday tasks. The good news is: Whether you’re looking to climb a fourteener or play with your grandkids, we can help!

Our team of Denver joint replacement specialists work diligently to help patients regain or maintain their independence and improve their quality of life. We treat a range of patients, including those experiencing disability and pain from arthritis. We treat other orthopedic problems, including deformities, infections, traumatic injuries, and failed joint replacements.

We consider every patient’s individual needs, from diagnosis to treatment and rehabilitation, to help them move toward an active, pain-free lifestyle. Patient support begins with patient education, including a discussion about which treatments are available.

Armed with both compassion and years of experience, our physicians are dedicated to listening, answering questions and including patients in the decision-making process.

Especially when it comes to arthritis, you don’t have to wait until the pain becomes constant or you have difficulty getting around. In fact, early intervention increases the chance of getting well without surgery. Our goal is to use conservative treatment options to keep patients active. Treatment for hip and knee pain depends upon your condition and the severity of your symptoms. However, in many cases, pain can be treated using over-the-counter or prescription medication, injections, specialized exercise programs or physical therapy.

Our Hospital, OrthoColorado, is Rated the #1 Hospital in Colorado for Joint Replacement

In a recent edition of Becker’s Hospital Review – the leading publication for healthcare industry leaders, they released the CareChex list of best hospitals for joint replacement surgery. OrthoColorado, Panorama’s physician-owned Hospital, was listed as the number one hospital for joint replacement in the state of Colorado!

CareChex, a divison of Quantros,  is known to be the most comprehensive site for rating medical care.  CareChex provides clinical, financial, and patient satisfaction findings to consumers, providers, and purchasers of U.S. medical care. Unlike other publicly available quality ratings, CareChex provides a comprehensive evaluation of inpatient hospital quality performance using a variety of outcomes of care measures. The organization also uses CMS Hospital Consumer Assessment of Healthcare Providers and Systems data, which provides patient satisfaction measures on physician and nurse communication, medication examination, pain control, care transition and several other areas.

The Panorama Difference - A Team of Joint Replacement Experts

At Panorama Orthopedic and Spine Center, our joint replacement surgeons believe that to offer the highest quality care you need to concentrate your experience in your area of expertise. The average orthopedic surgeon may perform 30- 40 joint replacement surgeries a year.  At Panorama, each of our joint replacements surgeons perform hundreds of joint replacements a year. Repetition breeds excellence and our surgeons are experts in this area.

If surgery is necessary, you can rely on our experienced team of doctors, who specialize in joint replacement and revision joint replacement. In addition, we have doctor’s specializing in the newest approaches to hip and knee replacement. These options are designed to help patients heal faster with less pain.

Using the anterior approach to hip replacement allows the surgeon to work between muscles, instead of through them. Dr. Chrastil, Dr. Peace, Dr Kinder, Dr. Thomas and Dr. Hugate are specialists in the anterior approach to hip replacement.

Patients typically experience a quicker and less painful recovery.

Specialized training and instrumentation enable Dr. Foran to perform traditional knee replacement surgery in a minimally invasive manner.  By using smaller incisions he is able to complete the surgery without cutting tendons or ligaments, and with less disruption to the soft tissues. This, too, allows patients to typically recover quicker.

Both Dr. Thomas and Dr. Lehman are two orthopedic surgeons certified in the use of Mako Robotic technology. The Mako System is a robotic-arm assisted technology that allows surgeons to precisely pre-plan joint replacement surgeries according to each patient’s unique anatomy. With the Mako System, CT (computed tomography) scans are taken of the joint and combined with the Mako technology which helps the surgeon place and measure the joint before ever beginning surgery. When in surgery the Mako System helps guide the surgeon but always allows for the surgeon to use his or her expert judgement to change the plan during surgery.

The Anterior Approach for Hip Replacement

Minimally Invasive Knee Replacement

Mako - Robotic-Assisted Joint Replacement

At Panorama Orthopedics & Spine Center, our goal is to offer our patients the best—and that means staying on top of the newest advances and offering patients options. In 1940 the first joint replacement was performed and now, over 70 years later, there is a new tool in joint replacement, the Mako robotic arm—now offered by Panorama’s experts in joint replacement surgery. Mako is a surgical assistance system that combines a robotic arm and Mako software that allows pre-surgical planning by a Mako certified joint replacement specialist and guidance during surgery.

The goal of the Mako System is to provide additional flexibility and better fit by providing more precision during placement—this should lead to less wear and tear over the life of the artificial joint. As patients get joints replaced at younger and younger ages, having a tool that is meant to prolong the life of an artificial joint becomes more and more important.

In traditional joint replacement surgeries, surgeons use imaging from MRIs and X-rays to get a picture of the joint, they make a plan and begin surgery; with Mako, a 3D model of the joint is created using CT imaging. Using this model, a surgeon is able to place the implant, rotate the joint, and extend and bend the joint to each patient’s unique anatomy before ever beginning surgery.


With a precise plan in place the surgeon will do the actual surgery using the Mako robotic arm. The Mako Robotic Arm gives feedback during surgery to help keep the surgeon to his pre-surgical plan just as a GPS would give guidance during a road trip. The surgeon is always able to make “detours” during surgery using their expert judgement.

The Mako robotic arm is a tool that the surgeon controls and moves with their hands throughout the duration of the surgery. Each surgeon who uses Mako goes through a training program to become certified and specifically trained in using the Mako robotic arm.  Dr. Tim Lehman, Dr. Bob Thomas and Dr. Todd Wente are certified Mako joint specialists and are happy to work with each patient to determine the best course of action for their surgery.

The Mako robotic arm is an option for the following surgeries:

  • Total knee replacement
  • Partial knee replacement

Panorama offers the Mako procedure at Littleton Adventist Hospital in Littleton and at Centennial Hospital. If you have more questions about Mako or think you would like to consult with a doctor please call to make an appointment with Dr Thomas, Dr Lehman or Dr. Wente.

Corey's Story of MAKO - Robotic Assisted Joint Replacement

Partial knee replacement - For some patients it can be a total solution to a partial problem

There tends be a lot of questions and often misconceptions around partial knee replacement. Is it as good as a total knee replacement? Why get a partial knee replacement when I can get a full replacement?  Some patients are skeptical because they think a partial replacement may only be a temporary solution.  If I get a partial replacement now, will I need to get a full replacement later?  Friends and family say why not just do the whole thing?   This is based on misunderstanding of what we are doing and why. For the right patient, a partial knee replacement is the total solution to a partial problem, and people who get partial knee replacements tend to be the most satisfied patients.


The History of Partial Knee Replacement

Partial knee replacements are not new.  They have been around since the 1970’s, however, results from the earliest partial knees weren’t as good as total knees at the time and they developed a bad reputation 30 or 40 years ago. There were several reasons for this.   First, the early implants and instruments used to put them in were not technologically advanced,  Second, because surgeons hadn’t quite perfected the surgical technique, and third, and probably most importantly, surgeons didn’t know how to choose the ideal candidate for a partial knee replacement.  Partial knee replacements, therefore, got a bad reputation with surgeons who tried the procedure with mixed success. Over the last couple decades, things have changed. The implants and surgical instruments are markedly improved and well-studied, the surgical techniques are refined and exacting, and we know now, based on decades of experience who is and who isn’t a good candidate for a partial knee.  In fact, modern data on partial knee replacements is excellent; Studies show that partial knee replacement patients tend to have higher satisfaction and better function than total knee replacement patients.  Additionally, several studies show that the longevity of partial knee replacements is quite similar to total knee replacement1.

Even though the modern data is excellent today, not all joint replacement surgeons have experience doing partial replacements, and many respected surgeons who were not trained with partial knees are biased by older techniques and outdated studies.

The Right Patient and the Right Surgeon

Not all patients are candidates for partial knees.  In order to have a successful partial knee replacement, we must select the correct patient for this type of surgery. Additionally, it is also very important to have a surgeon who specializes in this type of procedure. Dr. Jared Foran has been a leading researcher in partial knee replacement and performed more partial knee replacements than any other surgeon at Panorama.

The right patient for a partial knee replacement is one who has truly isolated arthritis in one of the three compartments of the knee. Arthritis that occurs in only one compartment of the knee is actually quite common—perhaps as high as 40 or more percent of patients. Arthritis occurs in only one compartment for a variety of reasons. Some examples:

  • Congenital or genetic predispositions such as bow leggedness or knock knees – may subject the inside or outside portion of the joint to abnormal stress and wear over time, while leaving the rest of the knee normal
  • Traumatic injury to one compartment of the knee (such as a meniscus tear), which leads to isolated cartilage damage to that part of the knee only.
  • Osteonecrosis, where one specific part of the bone dies or damaged, is another condition that may be an indication for a partial knee replacement.

X-rays, physical exam, and a careful patient history are used to determine how much arthritis is present and which compartment or compartments are involved. In rare instances, MRI or other studies can be helpful. The doctor will usually make the final decision in the operating room.  That is if during surgery the knee is opened and it is discovered that the arthritis is NOT isolated in one compartment only, then a total knee replacement can be done instead.

The benefits of a partial knee replacement

Patients who have partial knee replacements are some of the happiest!  In general, partial knee replacements feel more natural and have better function as compared to total knee replacements.  Often these patients may forget which knee was operated on over time. Some of the benefits of a partial knee replacement over a total knee replacement:

  • It is generally a faster, easier recovery with less pain and less downtime
  • It tends to feel more like a natural knee – it is often known as a forgotten knee – they feel so natural that patients don’t think about it anymore.
  • There is less risk for infection, blood clots, and stiffness.

Because this procedure is less painful, patients are often off pain medications within a couple days of their surgery. They are usually not requiring a cane or walker within a week. People are usually pleasantly surprised by how reasonable the recovery is.

As a surgeon it is our philosophy is do the minimum we can do to make the patient whole – whether that is operative or not.  If it is operative – we want to do the minimum needed to have a result that brings the patient back to 100%. In many cases the perfect solution is a partial knee replacement: “a total solution to a partial problem!”

Learning About Osteoarthritis with Dr. Patel

Complex Revision Joint Replacement

Sometimes referred to as revision arthroplasty, revision joint replacement is sometimes necessary when a joint replacement implant wears out, causes pain, becomes unstable, gets deeply infected, or starts to fail.

Complex joint revisions are thankfully uncommon and require a skilled surgeon to properly perform. Revision joint replacement surgery is complex and requires meticulous skill and planning. If it is complicated enough to require bone or joint reconstruction, it requires a doctor who is specialized in complex orthopedics.


At Panorama Orthopedics & Spine Center, Dr. Ron Hugate and Dr. Jeremy Kinder are both experts in complex revision and reconstruction. They provide other orthopedic surgeons and patients suffering from a failed joint replacement with a resource and a referral center.

While it is rare that a patient may need a joint revision, it is typically due to one of the following causes:

  • Loosening of the joint replacement parts, which leads to instability, reduced range of motion, and pain. Revision is done in this case to remedy the instability and reduced range of motion.
  • A fracture of the bones that hold the joint replacement implant in place could cause instability in the joint or a separation of the implants from the bone.
  • Infection in the joint, which can cause loosening of the implant and lead to stiffening and pain in the replaced joint.
  • Trauma to a joint with a joint replacement that results in implant breakage, loosening or instability.
  • Joint instability (joint “pops out”) when an implant wears out or is not properly positioned in the bone.
  • An implant wears out over a long time. If the plastic pieces in joint implants begin to wear that may be the only part that needs revision, in other cases, the entire implant may need to be revised or replaced.
