What Challenges Did This Patient Face Before Knee Replacement Surgery?
A 62-year-old patient from Thoppur, Madurai, visited Muthu Hospital with a long history of knee pain.
The patient explained that he had been experiencing knee pain for around 15 to 20 years. Over the last 5 years, the pain had increased significantly and started affecting his daily activities.
He found it difficult to climb up and down stairs. He was also unable to sit cross-legged or sit in a squatting position comfortably.
After consulting a few doctors, he came to Muthu Hospital to discuss his condition and explore knee replacement surgery.
During consultation, I first understand how the knee problem affects a patient’s daily life and discuss the treatment approach based on their condition.
Why Did This Patient Choose Knee Replacement Surgery?
The patient visited Muthu Hospital because his long-term knee pain was affecting his regular movements and comfort.
I explained to him that this was the third knee replacement procedure I was performing in this family. I had already performed knee replacement procedures for his wife and sister, and their trust brought him back for his own treatment.
For this patient, we planned a bilateral knee replacement surgery, where both knees were replaced.
The decision for knee replacement is based on understanding the patient’s concerns and evaluating their individual condition.
How Is a Knee Replacement Operation Performed Using Bone Cement?
During this knee replacement operation, bone cement was used to place the implant.
I explain to my patients that bone cement helps hold the implant securely in position. The cement is placed properly with the implant, and the implant is positioned carefully during the procedure.
I compare it with the strength we feel when cement is used in a building. In the same way, cement helps support the implant placement during knee replacement.
For this patient, the implant was placed using bone cement as part of the replacement procedure.
Knee Replacement Surgery Procedure Explained by Dr. Mithran
| Procedure Step | Explanation |
| Bone cement placement | Bone cement is used during implant placement in knee replacement surgery. |
| Implant positioning | The implant is placed properly with the cement during the procedure. |
| Knee movement check | Knee flexion and movement are checked after completing the implant placement. |
| Patellar tracking check | Patellar tracking is assessed after implant placement. |
| Alignment check | The knee alignment is checked to confirm proper positioning. |
| Bilateral knee replacement | Both knees are replaced as part of the planned treatment. |
How Long Does a Knee Replacement Last?
Many patients want to understand how long a knee replacement can last after surgery.
I explain to my patients that the bone cement used during knee replacement helps keep the implant securely positioned.
The cement is placed properly with the implant, and the implant is expected to remain in the same position for around 25 to 30 years.
I compare this with the strength of cement used in a building. Just as cement provides support in construction, the cement used during knee replacement helps support the implant after placement.
In this procedure, there is no need to wait for the bone to heal around the implant for fixation because the implant is secured with cement.
How Does Dr. Mithran Check the Knee After Implant Placement?
After completing the cementing process, I checked the knee carefully to confirm that everything was positioned correctly.
We assessed:
- Flexion of the knee
- Patellar tracking
- Overall alignment
The knee showed good flexion and proper patellar tracking. We also checked the alignment and confirmed that there was no varus or valgus stress.
The final assessment helped confirm that the knee replacement was positioned correctly.
Bilateral Knee Replacement Surgery: Completing Both Knee Replacements
For this patient, we performed bilateral knee replacement surgery.
After completing one leg in exactly 30 minutes, the anaesthetist confirmed that everything was fine. We then proceeded with the second leg.
The replacement procedure for both knees was completed as planned.
The patient’s body condition also helped make the procedure comfortable to perform.
