Case Study: Revision Total Knee Replacement

in a 68-year-old male with prior Unicondylar Knee Replacement

A retired banker presented to our office with worsening right knee pain. The pain was first noticed 6 months back when he was walking his dog. The pain subsequently got worse and disturbed his sleep. He had a partial knee replacement done by another physician about 5 years back for osteoarthritis of the medial compartment of the knee.

The pain was described as a dull ache which was non-radiating. The intensity of the pain was described as severe on activities and moderate on rest. The pain was especially worse on activities such as walking, getting up from a chair, climbing stairs, bending, kneeling, turning and twisting. He denied any associated fall or trauma.

He was currently taking over the counter pain medications. He denied any recent history of fever or redness of the knee. He complained of excessive stiffness on prolonged periods of rest. Currently, the pain severely restricted his daily activities. He was currently living with his daughter who accompanied him for the doctor’s office visit.

He was a former smoker having quit 10 years ago. He denied any known drug allergies. He was currently taking medications for hypothyroidism, asthma and high blood pressure. All his medical issues were well controlled with medications. Besides the Unicondylar knee replacement, He had a laparoscopic hernia repair 2 years ago and arthroscopic shoulder surgery a year ago.

On physical examination, there was mild swelling in the right knee. There was no rise in local temperature. The skin incision from the previous surgery was well healed. The gait of the patient was antalgic with a reduced stance phase on the right side. There was tenderness on the medial and lateral joint lines.

There was tenderness on patellar facets. Valgus and varus stress test at 0 degrees, 30 degrees, and 60 degrees was negative. Anterior drawer, posterior drawer, and Lachman test was negative as well. The entire arch of motion was painful. The range was from 10 degrees to 110 degrees.

The examination of the left knee, bilateral hips and ankles were normal. There was no distal neurological deficit. The bilateral lower extremity pulses were palpable and comparable. There was no bowel or bladder dysfunction. The lower extremity deep tendon reflexes were present and comparable.

He was advised a knee aspiration for gram staining, culture sensitivity, and biochemistry. He was also advised blood tests in the form of Hb, TLC, DLC, ESR and CRP (qualitative and quantitative).

The knee aspiration tests were negative for infection. The blood tests ruled out any active infection. The imaging studies revealed the failure of the Unicondylar knee replacement. He was advised for revision surgery in the form of total knee replacement. Risks, benefits, and alternatives were discussed at length with the patient. The patient agreed with the plan.

PREOPERATIVE DIAGNOSIS: Failed medial unilateral knee replacement.

IMPLANT USED: Tibial component size 2 with a stem extension 13 mm x 100 mm in length with size 2. 5-mm medial augment with flex 17 mm polyethylene with 32-mm patella, B.5-mm thickness, with Flex femoral component size C.

PROCEDURE: The patient was brought to the operating room after obtaining informed consent and signing the correct surgical site. The risks. benefits. and alternatives were extensively discussed with the patient prior to the procedure. The patient understands the increased risk of knee revision surgically.

The patient was definitively positioned and the right lower extremity was then draped and prepped in the usual sterile manner. Tourniquet cuff was placed over the right thigh. A time-out was performed. Antibiotics were given and the Esmarch was used and the tourniquet was then elevated.

The earlier incision was used for the arthrotomy. It was extended proximally and distally. Skin and subcutaneous tissues were incised. Medial parapatellar arthrotomy was then performed. The scar tissue was removed.

The tibia was then repaired. The component was loose and was removed. The tibia was drilled and then, the resection was made in the tibia to the fresh bone.

The tibia was then sized and it was decided to put a 5-mm augment on the medial side. The tibia was then prepared. Attention was then towards the femur. The femoral uni component was then removed. The distal and sample cuts were made on the femur.

The notch cut was then prepared. Medial and lateral laminar spreaders were used and the medial and the lateral cruciates and meniscus were then debrided. The gap was balanced in flexion and in extension.

Attention was then turned towards the patella after removing the scar tissue. The patellar excision was then performed and the trial patella was then placed into position. The trial femur was placed. The trial tibia was placed and trial poly was placed into position. The knee was then trialed through a full range of motion. The patellar tracking was good. The knee was stable in all range of motion.

The trial components were then removed. The femur was cemented into position. The tibia was cemented into position. Poly was then placed into position and the knee was held in full extension with a bump under the ankle. Patella was cemented into position and was held in position with a patellar clamp. Excess cement was then removed.

After the cement hardened. the knee was then again trialed and it was felt that the knee was loose in flexion as well as in extension. The knee was then trialed with 17-mm poly and was found to be stable in physiological flexion and extension. The earlier poly size was 12 mm.

The new poly size was 17 mm. Full extension and full flexion were obtained with the knee. Thorough lavage was given. The injection was given for pain control. Medial parapatellar arthrotomy was closed with Vicryl.

Cutaneous tissues were closed with #0 Vicryl. subcuticular tissues were closed with 2-0 Vicryl and skin was closed using Monocryl. Sterile dressing was then applied over the wound. The patient was then transferred to the postoperative care unit in stable condition.

The patient was advised by physical therapy and home exercise programs to increase flexibility and strengthen the muscles.

The sutures were examined to be clean, dry and intact. Three months post-op He demonstrated a full range of motion of the right knee with no pain. He was active again and expressed satisfaction at the results of the procedure. He was performing all his daily activities with ease.

I had such a wonderful experience with Complete Orthopedics in Stony Brook. Not only did Dr. Kuo fix my broken wrist with such kindness and care, but the office staff, including Billing, Reception and the X-Ray Technician, was always so helpful, going out of their way to ensure that each patient felt welcome, answering any questions with a smile, and ensuring any issues with insurance/billing were handled with the utmost professionalism. I highly recommend their practice!

I'm very happy St. Catherine's sent me to this office for treatment after I broke my collar bone! Unfortunately the break was too severe to repair on its own and I had to have it rebuilt a week after the injury. Dr. Vaksha did a great job fixing it. I'm three months out, and I have full use of the arm and shoulder. The whole office staff is very professional, accommodating, and welcoming. I hope to not need orthopedic services again, but Dr. Vaksha will be my number one choice if I or anyone in family suffers such am injury.

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
