What should be paid attention to before meniscal tear surgery?
If you and your specialist decide to have ACL surgery in Singapore for a torn meniscus, you may need some tests ahead of time.
For example, blood tests, an electrocardiogram, and a chest x-ray can help determine if you are healthy enough to tolerate surgery.
The anaesthetist will decide which type of anaesthesia you should have (to control pain) based on your medical condition:
1. Local anaesthesia is a form that numbs only the area of your knee.
2. Half-body anaesthesia is a method of anaesthesia that anaesthetizes the body from the waist down.
3. General anaesthesia is the anaesthesia that puts you to sleep in the form of
If you have local or partial anaesthesia, you may also need sedative medicine to help you relax. Normally, I can do routine meniscus surgery under local anaesthesia.
Before surgery, :
1. You should apply non-steroidal anti-inflammatory analgesics one day in advance to control postoperative pain.
2. Instruct you in advance on how to recover after surgery or order necessary braces or crutches.
3. Tell you how to prepare for the operation. You may need to stop taking aspirin and other drugs one week before the operation.
4. Fasting and water deprivation the night before the operation. (except anaesthesia) local
What happens during arthroscopic meniscus surgery?
The most common procedure for meniscal tears is knee arthroscopy. Usually, ACL surgery in Singapore takes less than an hour.
First, you are given anaesthesia. Doctors from our surgical team will disinfect your knee and cover the rest of your leg with a surgical drape.
I’ll make two small incisions (about 5mm) in your knee called portals. The knee joint is then filled with sterile saline. Salt water helps control minor bleeding in the joint and washes away debris, which helps the doctor see inside the joint.
I will insert an arthroscope, a small tool called into the incision. Arthroscope is a thin tube with a small light and video camera at the end. A camera projects a video image of the knee inside onto a monitor.
Arthroscopy and determine the surgical technique to repair:
1. Meniscus repair: Stitches the torn menisci together so they can heal independently. However, not all tears can be sutured, and the closer the meniscal tear is to the red zone (the area with the most blood supply), the higher the healing rate.
2. Partial meniscectomy: Trimming and removing the damaged meniscus leaves the healthy meniscus tissue in place.
Depending on the condition of the injury, the doctor uses other surgical tools. When a meniscectomy or meniscus repair is complete, your doctor may close the wound with stitches or even close the wound without stitches. Then your knee will be wrapped with a bandage.
What is the aetiology and mechanism of a knee meniscus injury?
When the knee is fully extended, the joint is stable, and there is less chance of meniscus injury. Sudden squeezing action and grinding force are the main causes of meniscal injury.
When the lower limbs bear weight and the foot is fixed, if the knee joint rotates during the process of extension and flexion, the meniscus is squeezed between the femur and tibia. While bearing vertical pressure, it also suffers from horizontal traction, or Shear pressure can easily cause damage to the meniscus.
When working in a semi-squatting or squatting position, such as coal miners squatting in the mine for a long time to shovel and throw coal, meniscus injuries are also prone.
