 Ligament Tear And Repair


The knee is susceptible to injury. Cruciate ligaments, meniscus and cartilage injury are common with sports injury. These diseases are amenable to early surgery.



Knee Surgery
Anterior Cruciate Ligament (ACL) Tears Reconstruction
during twisting, sudden stops, landing from a jump or during a direct collision

Symptoms
During the acute injury, usually pain is felt immediately around the knee and sometimes a popping sound can be heard as though something has torn inside your knee. Shortly thereafter there will be swelling. Occasionally, you may feel the pain and swelling sometime later after the injury has occurred. You may have difficulty standing and walking.

If you do not seek treatment and leave the ACL tear untreated, you may find your knee unstable when you do certain twisting motion, or make a sudden stop. You may even find your knee having episodes of pain and swelling after such episodes of instability.

Diagnosis
Your doctor will ask you questions about the injury and perform an examination on your knee. He may order X-rays or an MRI of the knee. Sometimes arthroscopy of the knee is required.

Treatment
The treatment options include non-operative and operative. Operative treatment is recommended for young and active athletes. The two common grafts for the surgery are patellar tendon and hamstrings tendon. The torn ACL is replaced with a new ligament. For patients who are not engaged in active sports or who are willing to modify activities to prevent instability episodes, non-operative treatment is recommended.

Types of Surgery
  • Bone-patellar tendon-bone autograft
  • Hamstring autograft

Rehabilitation
Rehabilitation with muscle strengthening, stretching and proprioception training is an important part of recovery whether you choose operative or non-operative treatment. Your physiotherapist will give a rehabilitation program with the aim to facilitate your recovery. Often the program may last for months.

Related prosthetic & orthotic services
You will be provided with an adjustable rehabilitation knee brace to facilitate early rehabilitation exercise. Your normal daily living can be resumed since the injured knee is controlled in a safety range. Functional knee brace can also be designed and fabricated for sports after recovery, protect the knees from re-injury.


Meniscus Surgery
Meniscus Tear
The knee meniscus acts as the knee shock absorber. It can be injured by twisting force. Small tear may heal by itself. Bigger and displaced tear needs surgery. Nearly most of the meniscus surgery is performed arthroscopically. The meniscus may be repaired or excised. You may need crutches and knee brace for a few weeks to protect the meniscus after surgery especially if it is repaired.
