Sad but true :(
Sometimes, I really wonder why did such an injury happen to me?!? It's frustrating knowing that my knee is not as strong as it used to be and could just give way at anytime when overworked and overstressed during high impact sports or activities.
It's not really giving me a lot of problem (at the moment at least) but some. My left knee gets tired very fast especially when I'm walking a lot. Besides that, other problems that I'm facing currently includes the hearing of popping sounds at times when I bend my knee, slight swelling, and instability of the knee (i.e., a "wobbly" feeling or a feeling that the knee is not solid).
There are 2 ways to go about it:
1) Non-surgical treatment:
A completely torn ACL has the slight potential of regrowth. The ACL primarily serves to stabilize the knee in an extended position and when surrounding muscles are relaxed, so if the muscles are strong, many people can function without it. The term for non-surgical treatment for ACL rupture is "conservative management", and it often includes physical therapy and use of a knee brace. Lack of an ACL generally increases the risk of other knee injuries such as torn meniscus, so sports with cutting and twisting motions are not recommended. For patients who frequently participate in such sports, surgery is often recommended.
2) Surgery
There are two main options for ACL graft selection, allograft and autograft. Autografts are the patients' own tissues, and options include the hamstring tendons or middle third of the patella tendon. Allograft is cadaveric tissue sourced from a tissue bank. Each method has its own pros and cons, hamstring and middle third of patella tendon having similar outcomes. Patellar grafts are often incorrectly cited as being stronger, but the site of the harvest is often extremely painful for weeks after surgery and some patients develop chronic patellar tendinitis. Replacement via a posthumous donor involves a slightly higher risk of infection. Additionally, donor grafts eliminate tendon harvesting which, due to improved arthroscopic methods, is responsible for most post-operative pain.
The surgery is typically undertaken arthroscopically, with tunnels drilled into the femur and tibia at approximately the original ACL attachments. The graft is then placed into position and held in place. There are a variety of fixation devices available, particularly for hamstring tendon fixation. These include screws, buttons and post fixation devices. The graft typically attaches to the bone within 6-8 weeks. The original collagen tissue in the graft acts as a scaffold and new collagen tissue is laid down in the graft with time. Hence the graft takes over 6 months to reach maximal strength.
After surgery, the knee joint loses flexibility, and the muscles around the knee and in the thigh tend to
atrophy. All treatment options require extensive physical therapy to build up muscle strength around the knee and restore range of motion. For many active patients, the lengthy rehabilitation period is more difficult to deal with than the actual surgery. In general, a rehabilitation period of 6 months to a year is required to regain pre-surgery strength and use. This is very dependent on the rehabilitation assignment provided by the surgeon as well as the person who is receiving the surgery. External bracing is recommended for athletes in contact and collision sports for a period of time after reconstruction. It is important however to realize that this type of prevention is given by a 'surgeon to surgeon' basis; not all surgeons will prescribe a brace for post surgery recovery. Whether the ACL deficient knee is reconstructed or not, the patient is susceptible to early onset of chronic degenerative joint disease.
After much discussions and considerations, I've decided the best thing for me to do is to opt for the surgery. It was tough weighing out the pros and cons but I'm now looking at the long term.
Yes, it may take a 6 months rehabilitation period to heal completely but that 6 months is nothing compared to the activities and sports that I'll be missing out for many, many more years to come.
Surgical treatment of the torn ACL usually involves an arthroscopic surgical reconstruction
Although a number of different types of tissue have been utilized to reconstruct the ACL, the most common type of ACL reconstruction involves harvesting the central third of the patellar tendon with a bone block at each end of the tendon graft. After performing a diagnostic arthroscopic examination of the knee, the central third of the patellar tendon is harvested.

The remaining tendon is then repaired. After harvesting the tissue, drill guides are used to place holes into the tibia (bone below the knee)...

...and femur (bone above the knee). By placing the drill holes at the attachment sites of the original ligament, when the graft is pulled through the drill hole and into the knee, it will be placed in the same position as the original ACL.
After pulling the graft through the drill holes and into the joint to replace the torn ACL, the graft is then held in place with bioabsorbable screws or metallic screws.

Fastening the graft in this manner allows new blood vessels to grow into the transferred graft and for healing to occur. Typically, the procedure is performed on an outpatient basis.

The last time I checked, the cost for the 2 hours surgery will be approximately a cool whopping RM20,000!!!
-__-'
But thank God, I've got medical insurance to cover up for me, i.e. 90% of the total cost. And better still, the maximum amount that I need to pay for the 10% is only RM1,000 even though 10% of RM20,000 is RM2,000.
So the moral of the story, please invest in a medical insurance. You'll never know how important it is when you need it. Medical expenses nowadays are absurdly crazy.
No joke.
To say I'm not afraid and nervous about the surgery is bullshitting. Of course I'm worried.
Will there be any side effects? How long will it take before I can be active again? Is it painful?
Sigh, so many questions running through my head.
All I can do now is to pray for God's strength to get me through this period of worrying. And also I need all the support and encouragement that I can get from everyone around me.
