Some issues Dr. Bruce R. Knolmayer, MD can help you with:

Hip Replacement

Hip replacement is a surgical procedure to replace parts of the hip joint that are damaged by disease or injury. It is most often done to treat arthritis, a common condition that causes stiffness and pain in the joints. Surgery is used only after other, less invasive treatments have failed to work.

The type of hip replacement patients receive is based on their age and the extent of damage to their hip. The hip joint has two parts: the femoral head, or hip ball, and the acetabulum, or hip socket. The hip ball is located on the upper end of the femur (thigh bone), and the hip socket is part of the pelvis. Depending on whether one or both parts require replacement, patients may need one of the following procedures:

  • Partial hip replacement, which is generally recommended in the case of hip fractures or other hip injuries. If a patient is having a partial hip replacement, only the hip ball will be replaced.
  • Total hip replacement, which is often used to treat the hip joint when it has become damaged due to arthritis. Both the hip socket and hip ball are replaced.
  • Hip resurfacing, which is usually performed for younger patients. A hip resurfacing procedure reshapes the hip ball and only replaces its surface. This preserves more bone and makes future surgeries easier. If a patient is having a partial hip resurfacing, only the hip ball is resurfaced and replaced. If a patient is having a total hip resurfacing, the hip socket will be replaced as well.

During hip replacement surgery, an incision is made along the side of the hip. The surgeon may access the joint directly through this incision, or by using small tools and a lighted tube called an arthroscope to see and treat the joint. The diseased tissue is removed, and the bones are smoothed out and fitted with metal ends. The metal pieces may be cemented in place, or they may have a porous structure that encourages bone to grow into them and hold them securely. A smooth plastic cushion is placed between the two bones to replace the cartilage and allow the joint to move freely.

Hip replacement surgery takes one to two hours, and afterwards patients may stay in the hospital for several days. When patients go home, they will have to use a cane, walker, or crutches at first. Patients will likely have physical therapy to improve their ability to move with their new hip. After the first few weeks, light exercise such as bike riding or swimming will help them heal, but certain actions, such as climbing stairs or bending over at the waist, may be difficult at first. It will take several weeks before they can drive or return to work. Full recovery may take six to 12 months.

Joint Aspiration

A joint is any area of the body where two bones connect. Due to injury or disease, the space between the two bones can sometimes become swollen and inflamed, which leads to pain and a loss of mobility. Injection and aspiration are two tools that physicians use to treat joint pain locally without needing to perform surgery.

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.

Shoulder Arthritis

Shoulder arthritis is a very common condition that causes pain, stiffness, or a grinding sensation in the shoulder. Some patients may hear a clicking or popping noise, and all symptoms are more noticeable when moving. Arthritis occurs when the cartilage that cushions joints becomes damaged.

Normally, when two bones come together inside a joint, they are separated by a layer of tough, smooth cartilage. The cartilage allows the bones to glide across each other, which makes movement easier. Cartilage can be damaged by an injury, by an illness such as rheumatoid arthritis, or by simple wear and tear (osteoarthritis). In the shoulder, the two joints most commonly affected are the AC joint (where the shoulder blade and collarbone connect at the outside edge of the shoulder), and the glenohumeral joint (where the arm bone meets the shoulder blade).

Treatment for shoulder arthritis may include:

  • Ice and rest
  • Exercise and physical therapy
  • Over-the-counter pain medications
  • Corticosteroid injections
  • Surgery

Surgical treatments include the removal of inflamed tissue and joint reconstruction. The type of arthritis and severity of the damage will determine which treatment is most appropriate.

This was my pre-op visit with Dr. Knolmayer. He explained the hip replacement surgery in detail including any complications that could occur and how he deals with them. He also talked about the recovery process. He was every thing I wanted prior to my surgery.
