Our Summary

This research paper discusses a procedure called total hip replacement, which is often performed to relieve pain caused by arthritis in the hip, usually due to a condition called hip dysplasia. The paper talks about two types of hip replacement implants available for small animals - those that use cement to secure the implant, and those that don’t. The INNOPLANT Total Hip Replacement system, which doesn’t use cement, is discussed in particular. This system is designed to keep as much of the natural structure of the hip intact, which helps maintain normal movement in the joint. However, this is a new system, so there is not a lot of data or long-term studies available on it yet.

Doctor’s Tip

A doctor may advise a patient undergoing hip replacement surgery to follow their post-operative instructions carefully, including physical therapy exercises and precautions to prevent dislocation of the new hip joint. It is important to keep the weight off the operated leg as instructed by the surgeon, and to avoid certain movements or positions that could strain the new hip joint. Staying active with low-impact exercises like walking or swimming can help promote healing and strengthen the muscles around the hip joint. It is also important to attend follow-up appointments with the surgeon to monitor progress and address any concerns.

Suitable For

Patients who are typically recommended for hip replacement surgery include those suffering from severe osteoarthritis in the hip joint, often caused by hip dysplasia. These patients may experience significant pain and limited mobility, impacting their quality of life. Total hip replacement surgery is considered a salvage procedure for these patients, aimed at alleviating their discomfort and improving their joint function. Commercially available total hip replacement implants, such as the INNOPLANT Total Hip Replacement system, offer options for both cemented and cementless components. The use of cementless components, such as screw-in endoprosthesis, can help improve implant stability and maintain more normal anatomic structure and biomechanics of the hip joint. While there is limited data and few long-term studies available in veterinary literature on these newer systems, total hip replacement surgery remains a viable option for improving the quality of life for patients suffering from severe hip osteoarthritis.

Timeline

Before hip replacement:

  1. Patient experiences chronic hip pain and stiffness, often leading to difficulty walking and performing daily activities.
  2. Patient undergoes diagnostic tests such as X-rays and MRI to confirm the extent of hip damage.
  3. Orthopedic surgeon evaluates the patient’s condition and recommends total hip replacement as a treatment option.

After hip replacement:

  1. Patient undergoes preoperative preparation, including blood tests, physical therapy, and consultation with an anesthesiologist.
  2. Total hip replacement surgery is performed, typically lasting a few hours.
  3. Patient stays in the hospital for a few days for monitoring and rehabilitation.
  4. Patient undergoes postoperative physical therapy to regain strength and mobility in the hip joint.
  5. Patient gradually resumes normal activities and experiences reduced hip pain and improved quality of life.
