Case Study: Custom Left Knee

Replacement in a 59-year-old female

The patient is a 59-year-old female who presented to our office with complaints of bilateral knee pain (left greater than right). She stated that the pain started 4 years back insidiously which has worsened over time. She is a former track and field athlete and feels her knees deteriorated due to her sporting career.

The patient is presently working in a consulting firm which requires her to be seated for long hours. She states that her knee pain is getting worse and she finds it difficult to stand from her sitting position. The patient states she previously enjoyed going for a stroll which she is now unable to do secondary to pain. She finds it difficult to bend her knees or climb stairs limiting her daily activities.

She had lower back surgery done 2 years ago with excellent relief from symptoms. The patient also stated she had an open reduction and internal fixation with a screw secondary to slip and fall in left upper tibia 20 years ago. She had an episode of myocardial infarction 5 years ago and is currently on coronary artery disease medications. Her hypertension is well controlled with medications.

The patient stated she had multiple knee gel injected but the initial pain relief didn’t last. She also had a trial of conservative management in the form of braces, pain medications, and physical therapy but with only temporary relief. She stated she now has lifestyle limiting knee pain.

The patient’s physical examination revealed a horizontal scar over the left tibial tubercle. There was mild swelling with genu varus and flexion deformity. The range of motion of the left knee was found to be 10-95 degrees. Medial joint line and medial patellar facet tenderness were elicited. The patient was visibly under distress due to pain. She stated she wanted to explore the options of knee arthroplasty.

Her imaging studies revealed tricompartmental osteoarthritis of the left knee with a retained hardware (bolt) in the left proximal tibia. After assessing her medical conditions and physical examination she was deemed as a candidate for custom knee replacement. She was advised to undergo only the left side in view of the previous history of myocardial infraction and then proceed for right knee.

Risks and benefits were explained at length to the patient. She was made aware of alternative treatment options. She decided to go ahead with a left custom knee replacement.

The patient underwent a preoperative CT scan a few weeks before the surgery. The data was used to create custom 3D printed instruments and patient-specific unique implants. The data was utilized to create a preoperative plan outlining bone cuts and femoral offsets. The custom implants ensure that maximum bone is preserved and the biological biomechanics are recreated.

Laminar spreaders were used medially and laterally, with medial and the lateral remainder of the meniscus, and the cruciates were then debrided. The posterior osteophytes were then removed.

Attention was then turned towards the patella. Patellar resection was performed. The drill holes were made in the patella. Trial patella was placed into position. Attention was then turned back towards the tibia.

Scheduling my appointment was quick and easy. The staff was super friendly and down to earth. I was seen on time. The appropriate test, “x-rays” were taken before the conversation with doctor, something I really liked, test for analysis and conversation was done upfront. Dr. V had a great personality and was no BS, straight forward diagnosis and a play on next steps. I am happy I found them and would refer them to friends and family.

After suffering from a severe ankle injury Dr. V was able to help me heal and return back to work completely to a job where I stand for 12 hours a day. The office is very clean and I appreciated the reminders of my appointments via phone call and through text. The patient portal made it easy for me to access all my documents including work notes. The office staff is wonderful and Rebecca was able to schedule me with a busy schedule and awesome at answering all of my questions including referring me to a great physical therapy office. I highly recommend this office to anyone who’s looking for knowledgeable and kind orthopedic office.

I was rear ended in an auto accident , Dr Vashka was recommended by a friend of mine .I was experiencing Back , neck , and shoulder pain . After a thorough examination and given exercises to do at home , I am feeling much better , and I ended up avoiding surgery . The staff at Complete Ortho is extremely attentive and show great care when making an appointment and are very friendly and i never waited more than 5 minutes for my appointment . So I would strongly recommend Complete Orthopedics for any aches and pains that one might be experiencing.....

It was the afternoon of Friday Sept. 24. We were in Pt. Jefferson and my wife, Mary Ann, broke her hip. We went to Mather Hospital and it was determined that she would have to have an operation to have it repaired. This would be her third time under the knife in the past year. It just so happened that we were very fortunate enough to have Dr. Karkare, who was on standby, perform the surgery. He put in a rod and two screws in her hip. She spent a few days in the hospital and then went to Gurwin rehabilitee for another few weeks.It has now been almost six weeks and we both worked the election the other day. If it wasn’t for Dr. Karkare’s expertise she never would have been able to work. She is able to walk with a walker and is doing physical therapy three times a week.We can not thank the doctor enough for the compassion and dedication that he puts into his work. It allows Mary Ann do the things that she likes to do, even on a limited basis for a while. I know that with her will, perseverance and the great work that the surgeon performed she will be back on her feet in no time.Sincerely:John V. PlumpEast Northport, NY 11731

In the year of 2018 I was referred to Dr. Karkare because I was experiencing severe knee joint pain. After exhausting physical therapy and trying to labor through the pain, I had to make a quality of life decision. Total knee replacement was the only viable option. Dr. Karkare made my decision easy as he walked me through the whole process from surgery to recovery.On 12/13/19 ( Friday the 13th) I enter Lenox Hill Hospital in great hands. From the time I entered Dr. Karkare’s office for the first time until now, his staff has been amazing. Andrea the medical coordinator walked me through all the paper work and necessary preparations for the surgery. Courtesy and kind would be an understatement. Dr. Karkare went over and beyond from the wellness checks and phone calls all to assure me that I was important to him. This was the right decision no pain and no limp. Complete Orthopedics should be your choice!

I suffered with pain in both knees for years. My orthopedic doctor kept recommending knee replacement . I fought it for years, as I was just afraid. When I had no choice and could barely walk , it was recommended I see Dr. Karkare. We set up a consultation and my wife and I left his office feeling totally confident and comfortable with moving ahead with the surgery. He explained everything to us, and the office staff set everything up for us and made the process easy. So about one month after our initial meeting I had the first knee done. I was up walking mere hours after the surgery, and on the workout machines the next morning. I went home two days after the surgery, and yes walked my daughter down the aisle at her wedding only one week after the surgery without even a cane! Three months later I had the other knee done and went home the very next day. Dr. Karkare put my fears to rest . I would highly recommend him. His expertise gave me my life back. Thank you Dr. Karkare.SincerelyVito Congro
