Knee arthroscopic surgery is a key hole procedure performed through small incisions in the skin to repair injuries to tissues such as ligaments, cartilage, or bone within the knee joint area. The surgery is conducted with the aid of an arthroscope, which is a very small instrument guided by a light source attached to a television monitor. Other instruments are inserted through two incisions around the knee. Arthroscopic surgeries range from minor procedures such as flushing or smoothing out bone surfaces or tissue fragments (lavage and debridement) associated with osteoarthritis, to the realignment of a dislocated knee and ligament grafting surgeries. The range of surgeries represents very different procedures, risks, and aftercare requirements.
Diagnostic Arthroscopy Introduction
Arthroscopic surgery allows diagnosis and treatment of joint problems through small incisions in the skin. A camera attached to a scope is used to see inside your joint.
Small incisions (portals) are made around the joint. The scope and surgical instruments will go into these incisions.
The scope is inserted into the knee. Saline solution flows through a tube (cannula) and into the knee to expand the joint and to improve visualization. The image is sent to a video monitor where the surgeon can see inside the joint.
Using the video monitor as a guide, the surgeon can make a diagnosis. A variety of surgical instruments like this probe can be inserted through other incisions to treat specific problems.
End Of Procedure
The surgical instruments are removed and the procedure is completed.
What is Hyaluronic Acid?
Hyaluronic Acid viscosupplementation injects a preparation of hyaluronic acid into the knee or hip joint. Hyaluronic acid is a naturally occurring substance around in the synovial (joint) fluid.
It acts as a lubricant to enable bones to move smoothly over each other and as a shock absorber for joint loads. People with osteoarthritis ("wear-and-tear" arthritis) have a lower-than-normal concentration of hyaluronic acid in their joints.
Viscosupplementation may be a therapeutic option for individuals with osteoarthritis of the knee. Viscosupplementation has been shown to relieve pain in many patients who cannot get relief from nonmedicinal measures or analgesic drugs.
What are the risks of HA Viscosupplementation?
The simple procedure involves injecting the HA into the joint affected. The risks involved are similar to any injection, including bleeding, infection, and possible adverse reactions.
What happens during a HA Viscosupplementation?
The physician will administer local anesthesia to the area being injected. This will prevent excess pain and discomfort during the procedure itself. The HA injection will be ready to be administered in a prefilled syringe. The surgeon will first aspirate the affected joint to remove any fluid that may be present. After removing the fluid, the HA is injected into the joint. You will be able to get up and walk immediately after the procedure.
What activity can I do after I receive HA Viscosupplementation?
During the first week after HA Viscosupplementation, heavy and strenuous exercise involving the affected joint should be avoided. However, you can continue your regular daily activities as normal.
How many treatments do you need?
Most patients only require one HA Viscosupplementation once a year depending on the severity of osteoarthritis. If your condition is more advanced, you may require to have the injections repeated again between 6 months to 9 months after the first treatment.
How does HA Viscosupplementation work?
As a natural component in your joints, Hyaluronic Acid provides joints a smooth surface to allow movement. Over time, the concentration of Hyaluronic acid in your joints decreases, the joints can not move freely causing pain and discomfort. With HA Viscosupplementation, it seeks to restore the concentration of HA to that of a normal healthy joint. This leads to reduce pain, and increased functionality of the joint.
How long does it take for HA Viscosupplementation to "work"?
Most patients notice some element of improvement almost immediately after HA Viscosupplementation. As time goes on the pain and soreness related to the injury decreases, increasing the ability to do functional daily living activities.
