BONES OF THE KNEE:
The femur (thigh bone), tibia (shin bone), patella (knee cap), fibula (smaller bone next to shin bone).
Muscles, tendons and ligaments connect the knee bones. The kneecap glides in a groove in the thighbone and adds leverage to the thigh muscles, which are used to extend the leg. The thigh bone and shine bone come together at the knee joint and move on one another when bending or straightening the leg.
KNEE JOINT CAPSULE:
Four main ligaments connect the bones of the knee:
Two ligaments are in the center of knee and are bathed in joint fluid - the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL)
The other two ligaments are located on the outside of the knee joint - the medial collateral ligament (MCL) on the inner side and the lateral collateral ligament (LCL) on the outer side.
Ligaments on outside of kneecap usually heal by themselves. Ligaments in the center of the knee rarely heal on their own because they are bathed in joint fluid and lack a blood supply.
CARTILAGE OF THE KNEE: Connective tissue that absorbs shock. The two types of cartilage are: Articular & Meniscular.
Articular Cartilage:
Meniscus (Meniscal Cartilage):
MUSCLES OF THE KNEE:
Hamstrings: Muscles on the back of thigh attach to tibia (shin bone) at back of knee. Used to bend the knee.
TENDONS OF THE KNEE:
The medial meniscus is a semi-circular structure which is wider toward the back of the knee than toward the front. The anterior horn of the medial meniscus is attached to the tibial plateau, just in front of the area where ACL attaches. The anterior often "drops off" the tibial plateau with the majority of its insertion sitting below the knee joint itself. The posterior horn of the medial meniscus is firmly attached to the tibia in the back of the knee near the attachments of the lateral meniscus and the PCL.
Lateral Meniscus:
The lateral meniscus is almost circular and covers a larger portion of the lateral tibial plateau when compared to the amount of medial meniscus covering the medial tibial plateau. The lateral meniscus is approximately the same width in both the front and back. The anterior horn of the lateral meniscus attaches to the tibia in front of the intercondylar eminence in association with the ACL. The lateral meniscus is more loosely attached to the joint capsule than the medial meniscus.
(The MR scan)-I guess it's approximately similar with what the doctor so called the MRI.
Functional Anatomy:
When the knee bends, the menisci move toward the back of the knee. As the knee straightens, they move toward the front of the knee. The menisci act as "shock absorbers" and reduce the force per unit area on the proximal tibia. Loss of meniscal tissue increases stresses on the joint surface and predisposes the development of osteoarthritis. In addition, the presence of the menisci may provide some stability to the knee in cases where the ligaments are deficient.
(Arthroscopic view of a discoid lateral meniscus)
(This is the reseach I done, not mine, I guess it's almost the same.)
On occasion, the lateral meniscus may be "discoid". In this case, rather than tapering centrally, the meniscus occupies the entire space between the tibia and and femur. Patients who have discoid meniscus may complain of audible "snaps" during flexion and extension of the knee.
The doctor suggested me to go for the surgery operation as called sloppy. In addition, this operation before you can be choosen to do the MRI check first as you seen the previous pic, and they will ensure what the problems it's going on with. Thereby the MRI cost will be around $750 and after that sloppy operation will cost around $3-5k. Ohmygod. Not even I were worried about the financial, but also the risk of doing it. From my life experience, I had never ever even been it this cirtumstances before, I'm worry about does it be any side effect after the operation? do I still can go sport as previous? How risks will be in this operation and also probability of succession? I absolutely fright up once our topics on going. And this time mum told the doctor to allow me therapy with medical pil first, we will deciding it on next. After that mum got me a lesson on car about don't simply go for surgery first, we should also go for other few osteoarthropathy specialise doctors to see, she said nowadays those doctors are like this, wasn't really can believe with, they required peoples do operations alway, but what the viewpoint inside that is to earn more money they can. As I keep thinking to, its wasn't wrong as well, and I taken mum suggestion, take pils in punctual, bless to mine knee what I can do now.
(The figure upon will be similar with the surgery operation like may be I'm doing)
(It's horrific in it?)
(The following figure as well)
(The Leg Bone's Connected to the Knee Bone/The Left Hemisphere's Connected to the Right Foot)
If you’re watching the track events in the Olympics, notice that when the sprinters get down into their starting blocks, some of them have their left foot back to push off with and others have their right foot back.
Big deal, eh?

Bro...very sad when hear about ur knee problem...i feel more and more sad when u got problem i cant even help u!Sorry ya...i just hope that u can take good care about ur knee...if got other problem try call other ppl help u first...if u need i be the 1st person stand up for u!hehe...i'm not gay~i just appreciate u this bro...although we didn't closed just like before but don't matter how 1 day is my bro then u will be my bro forever!Pls PLs walk slowly...don't go sepak bola edi...i can do more part time job and earn some extra money...if u can't paid about ur operation fees i cant borrow u...For me money can earn back but a good bro cant!i just hope u will be fine~tk ya...remember wat i say...find me if u got problem!
10s.concerning man.It ok. I din choose to operation yet, not dare to be 1st, coz not the 100% grasp. U manage ur finance better too, although u hv hard got strungle wit those money frm job, but spend less wit save more, its not easy to earn, buy less those "needs".
