Debridement can be performed either surgically or nonsurgically; some methods are less invasive than others. Doctors select the appropriate debridement technique by considering the location, cause, and size of a patient's wound and may also weigh the patient's overall wellbeing, age, and risk of infection.

Surgical debridement is performed by cutting away dead, infected, and hyperkeratotic skin with a surgical scalpel. For deep wounds that tear away the skin and go into the muscle, skin from another region of a patient's body may be grafted onto the wound, which may then be periodically assessed and rebandaged until fully healed.

Non-surgical debridement is achieved with water or a dissolvent gel. Water softens the damaged skin and affected tissue, allowing doctors to remove it with wet-to-dry dressing. When wet tissue dries, it adheres to the dry dressing or bandage and comes off when the dressing is pulled away. In contrast, dissolvent gel deconstructs tissue, which can be cleaned off of the wound. Nonsurgical debridement is less invasive than surgical techniques; however, it can entail repeat treatments, slowing wound recovery.

While the prospect of stripping away skin may seem jarring, debridement can be critical to the treatment and healing of wounds which cannot not heal independently.

Both injection and aspiration are techniques that involve inserting a needle connected to a syringe directly into the joint. Aspiration involves the removal of excess fluid, and injection is the placement of medication directly into the joint space via the needle. Both procedures may be performed at the same time. In both cases a local anesthetic may be used, the skin will be cleaned and disinfected, and then the needle will be inserted. In some cases, especially if the injection or aspiration is in a large and deep joint such as the hip or spine, ultrasound may be used to guide the needle to the exact location desired.

In some cases, irritation to the joint can cause fluid to build up so significantly that the joint hurts and can no longer move well. Aspiration removes some of the excess fluid and relieves the pressure. In addition, aspiration can be used to provide a sample of joint fluid if it needs to be examined microscopically for the presence of white blood cells, bacteria, or crystal formations.

Certain injuries and diseases that affect joints are inflammatory in nature, such as rheumatoid arthritis, tendonitis or gout. These diseases may be helped by the local injection of anti-inflammatory medications directly into the affected joint. In this case, corticosteroids such as methylprednisone are usually used. Relief from the pain may be felt right away and may last for weeks or even months.

In some cases, such as with osteoarthritis, the cartilage buffer between the two bones wears down and pain comes from bones rubbing against each other. In this case, injection of a lubricating agent such as hyaluronic acid may be beneficial. It provides a slippery cushion between the bones to relieve pain that can last for months.

There are many benefits to robotic surgery, both for the patient and the surgeon. Robotic surgery allows for more precise movements and increased control during very delicate surgical procedures. This makes performing surgery accurately much easier for surgeons and reduces fatigue. The smaller 'hand' of the robot can enter the body via a much smaller opening, which reduces the risk of infection and scarring and leads to a faster recovery. The robotic hands also contain tiny moveable cameras among their tools, giving surgeons a much closer view of the procedure than would be possible with traditional surgery.
