Joint Replacement

Patients receiving hip, knee and shoulder replacements at Winneshiek Medical Center may benefit from minimally invasive surgery, or surgery using just one or two small incisions. Because of continued research and technological advances, orthopedic surgeons have the resources available to perform surgeries resulting in less pain and faster rehabilitation when compared with traditional joint replacement surgery.

According to the American Academy of Orthopedic Surgeons, patients generally experience less pain, more cosmetic incisions, less muscle damage, faster rehabilitation and shorter hospital stays following minimally invasive surgeries.

Goals of joint replacement surgery at Winneshiek Medical Center are:

  • To relieve pain
  • Restore function
  • Increase activity
  • Maintain a full and active lifestyle

Types of Joint Replacement Available at Winneshiek Medical Center

Uni-compartmental (Partial) Knee Arthroplasty
Minimally Invasive Total Knee Arthroplasty
Standard Total Hip Arthroplasty
Minimally Invasive Total Hip Arthroplasty (Direct Anterior Approach -DAA)

Uni-compartmental (Partial) Knee Arthroplasty

Another name for a uni-compartmental knee arthroplasty is ‘partial knee replacement.’ During surgery, the damaged part of the knee is removed and replaced with artificial parts.

Partial knee replacement involves removing a relatively thin amount of bone from the end of the thigh bone and the top of the leg bone. All of the major ligaments and tendons of the knee are left in place and rebalanced so that the knee straightens and bends, and is stable from side-to-side and front-to-back after surgery.

The surgery typically lasts about one to two hours. After surgery, you will rest in the recovery room for about two hours. Most people can leave the hospital after a one- or two-night hospital stay.

The benefits of a partial knee replacement may include a less invasive surgery and a smaller incision. The procedure also removes less tissue from both the tibia and femur than a total knee, because only the damaged bone and cartilage are removed. Since the implant saves more tissue, a future total knee replacement can be more easily performed, if it is necessary.

Uni-compartmental knee arthroplasty is most suitable for people with good knee flexibility, damage to just one side of the knee joint and normal knee ligaments.

Minimally Invasive Total Knee Arthroplasty

Total knee replacement can be an extremely successful surgical procedure. Total knee replacement, also called arthroplasty, involves removing the diseased bone and cartilage and resurfacing it with orthopedic implants. The word ‘replacement’ makes one think that surgeons remove the entire knee. In truth, your surgeon only resurfaces damaged bone and cartilage at the ends of the bones in your joint. During surgery, the joint is exposed by an incision, made down the center or off to the side of the knee. The damaged bone ends are then resurfaced with components designed to re-create the natural contours of the bones in a healthy knee. The metal and polyethylene (plastic) implants allow the bones to smoothly glide against each other, much like natural cartilage.

Total knee replacement is performed while you are under anesthesia. There are various types of anesthesia available and your physician will explain your options to you before surgery.

The length of surgery may be approximately 1 ½ – 2 hours. Care before surgery and time spent in the recovery room can add an additional two to three hours before you are back in your hospital room.

Standard Total Hip Arthroplasty

Total hip replacement surgery is also called total hip arthroplasty, which means surgically replacing the hip joint.

During surgery, the damaged part of the hip is removed and replaced with artificial parts. An incision is made on the side, or toward the back, of the hip. The incision requires surgeons to cut through muscles and tendons, which need time to heal. During the healing process, patients are typically prescribed extensive physical therapy to regain strength and stability in the joint.

The surgery typically lasts about one to two hours. After surgery, you will rest in the recovery room for about two hours. Most people can leave the hospital after a two-night hospital stay.

Following a total hip replacement surgery, Transitional Care at Winneshiek Medical Center might be an option for you as you recover.

Minimally Invasive Total Hip Arthroplasty (Direct Anterior Approach)

Unlike traditional minimally invasive hip replacement techniques, the Direct Anterior Approach (DAA) technique uses an incision at the front of the hip instead of the side or back of the hip. The modified incision placement allows surgeons to directly approach the hip joint by going between the muscles that surround the hip joint. Traditional approaches would require cutting the muscles and/or tendons that surround the hip.

The Direct Anterior Approach minimally invasive hip replacement procedure is designed to reduce trauma to the tissues surrounding the hip joint. By preserving the muscles and tendons, surgeons may enable their patients to walk the day of surgery, to experience less postoperative pain, and to return to daily activities more quickly.

Traditional Hip Replacement Direct Anterior Approach
8-12 inch incision
Surgical approach – side or back
Disturbance of the joint and connecting tissues
3-4 inch incision
Surgical approach – front
Muscles or tendons not detached.
