Minimally Invasive Subvastus Total Knee Replacement
This procedure promises lesser pain along with quick recovery and is performed by pushing the muscles to the side-following the Sub Vastus approach instead of cutting the muscles. This treatment is cosmetically appealing because the skin is cut only upto 8-10 cms. Also, the kneecap is not flipped as in the conventional method but it is only pushed to the side to expose the joint. Due to this, the strength of the muscles in front of the thigh extensors is preserved. The bones are not separated from each other but they are cut in place, which minimizes the stretch injury to the structures surrounding the joints. This approach can result in significantly less trauma to the leg, faster healing and more strength and mobility in the new knee.
Along with good pain control measures, minimal pain after the surgery is ensured. The patient will be able to lift the leg immediately after the surgery and can stand and walk with support the same day. The knee can be bent upto 90 degrees and the patient will be able to walk atleast 100 steps by the 3rd day-at the time of discharge. After 2 weeks time, they will be able to walk independently without any support and getting up from the sitting position becomes easy in 1 to 2 months time. Within 2 to 3 months, they will be able to stand for a long time and walk any distance without suffering from any heaviness in the thigh muscles. In other words, the patient tends to forget the knee surgery in 2-3 months and will be able to resume their day to day activities comfortably.
