Autologous Bone Marrow Concentration for Avascular Necrosis of Femoral Head

April 11, 2020 updated by: Pei-Yuan Lee, MD

The Effect of Autologous Bone Marrow Concentration Combined With Core Decompression for Avascular Necrosis of Femoral Head

This study aims to evaluate the effect of bone marrow concentration on avascular necrosis of femur head by comparing clinical and imaging outcomes between patients receiving core decompression surgery with intraoperative bone marrow concentration and those receiving core decompression surgery only.

Detailed Description

Avascular necrosis (AVN) of femoral head is a progressive disease that predominantly affects younger patients. Although the exact pathophysiology of AVN has not yet to be elucidated, the disease is characterized by a vascular insult to the blood supply of the femoral head, which can lead to collapse of the femoral head and subsequent degenerative changes. Mesenchymal stem cells (MSCs) are pluripotent cells that can differentiate into multiple mesenchymal tissues, including tenocytes, chondrocytes and osteoblasts, as well as being a source of multiple growth factors to establish an environment conducive to soft and hard tissue regeneration. As bone marrow concentration has high concentration of mesenchymal stem cells, several studies have applied the autologous bone marrow concentration in halting the progression of AVN of femoral head. However, a higher level of evidence for its use on patients suffering from femoral head avascular necrosis has not been reported. This clinical trial will evaluate and compare the eligible patients who undertake core decompression surgery plus intraoperative bone marrow concentration with those who received core decompression surgery only. All patients will be followed for one year and clinical and imaging outcomes will be compared and analyzed.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
3-month postoperative hip function evaluated by Harris Hip Score
Time Frame: 3-month postoperative
Hip function is evaluated using Harris Hip score. The survey has 10 question items and scores range from 0-100 with higher scores representing less dysfunction and better outcomes.
3-month postoperative

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
