Meniscus surgery is performed under general anaesthesia or anaesthesia near the spine, during which the leg avascularised from the femur downwards with a tourniquet. The knee specialist makes several, approx. half a cm incisions next to the patellar tendon, through which the surgeon introduces the arthroscope and the special tools needed for surgery. The joint is filled with physiological saline so that the knee is clearly visible, as well as injuries and degenerative lesions. During meniscus surgery, the goal is to save the cartilage of the knee joint as much as possible, because its removal increases the instability and accelerates the wear of the cartilage surfaces.
The torn, pinched part is excised by the doctor, or in a favourable case, lesions in the so-called red zone are fixed back to the cartilage base. At the end of the surgery, the surgeon closes the wounds with small stitches.
After a day’s hospital stay, the patient can leave for home after learning the necessary gymnastics and walking exercises. After partial meniscus removal, the operated knee can be loaded the next day, but in the case of a sutured meniscus injury in the red zone, 4 weeks of relief/crutching and thrombosis prevention treatment are required.
If an early complication does not develop, the sutures will be removed after a week, and rehabilitation may begin if necessary. The patient may return to a lifestyle of average activity one week after partial meniscus removal, but exercise and strenuous physical work are recommended only gradually, 3 to 6 weeks after surgery. In the case of a sutured meniscus injury, gradual loading of the limb may begin on the 5th week after surgery.
