Many middle-aged and elderly people suffer from knee pain, which can make it difficult to walk. Some have repeated swelling and pain in the knee; some have to rest after walking a short distance, and are reluctant to go downstairs; some often feel as if there is something in the knee walking around like a mouse; some always feel as if the knee is always tripped up, and so on. These are mostly due to “degenerative disease”, which is commonly referred to as “aging”, and is actually caused by damage to the meniscus inside the joint, cracking of the cartilage surface, and normal secretion disorders. Just like the brake pads of a car, the damage must be repaired and replaced in time so that it can be used normally again. Meniscus and cartilage damage inside the knee needs to be repaired just like damaged brake pads, but of course it is relatively difficult to replace them. If the damaged meniscus inside the knee joint is repaired, the broken cartilage fragments are removed, and the abnormal disease-causing factors inside the joint are flushed out, it will continue to run like a rejuvenated old car. How does this work? Do we need to make a big, big incision in the knee joint? No, now we can use a very minimally invasive method, the “arthroscopic” method, which only requires two small incisions of about one centimeter in the front of the knee joint to solve the problem. In the past, a large incision of more than ten to twenty centimeters was required. And you can walk normally on the ground two or three days after the surgery. You will be able to get a lot of relief from your knee pain and discomfort with just a fraction of a second. Of course, arthroscopic surgery can not only solve these problems, but also for intra-articular ligament damage, synovial lesions, patellar dislocation (congenital and acquired), some patellar fractures, tibial plateau fractures, etc. can be treated by this minimally invasive method. This procedure is a good option for ladies and gentlemen who love beauty in case they encounter similar lesions.
