Osteoarthritis of the knee is one of the most common causes of disability among elderly. As the disease progresses the cartilage become frustrated, surrounding bone react to become thicker and inflammation occurs in subchondral bone seen in T2-weighted MRI as increase in signal density. Patients are treated initially by pain management. In patients who don't response to first line treatment invasive treatment like total knee replacement is done. The investigators designed this clinical study with the aim of evaluating therapeutic effects of intra-articular injection of bone marrow mesenchymal stem cells (BM-MSCs) in patients with severe knee osteoarthritis.

Primary Outcome Measures:
  • physical function improvement [ Time Frame: 2weeks ]
    Evaluation the physical function improvement Measured by WOMAC osteoarthritis index after cell injection.

  • change in pain density [ Time Frame: 2 weeks ]
    Evaluation the changing of pain density measured by Visual Analogue Scale after cell injection.

Secondary Outcome Measures:
  • joint swelling [ Time Frame: 3months ]
    Evaluation the joint swelling by physical examination after intra articular cell injection.

  • joint erythema [ Time Frame: 3months ]
    Evaluation the joint erythem by physical examination after cell injection

  • deterioration of joint function [ Time Frame: 3months ]
    Evaluation the deterioration of joint function by physical examination after intra articular cell injection.

  • Allergic reactions [ Time Frame: 3months ]
    Evaluation the allergic reactions like skin rash,skin erythema,dyspenea by physical examination after cell injection

Enrollment: 40

Study Completion Date: October 2015
Primary Completion Date: September 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: mesenchymal stem cell
Patients with knee joint osteoarthritis who underwent intra articular mesenchymal stem cell injection.
Biological: mesenchymal stem cell
intra articular injection of mesenchymal stem cell
Other Name: stem cell transplantation
Experimental: placebo
The patients who are in control group and underwent placebo injection.
Biological: Placebo
Patients with knee joint osteoarthritis who underwent intra articular placebo injection

Detailed Description:
This is single center, randomized, triple blind phase II clinical study. Patients will be divided into two groups of case and control. All subjects will undergo bone marrow aspiration. Mesenchymal stem cells will be isolated from bone marrow, cultured and transplanted back to the knee joint. Patients of case group will receive cell injection 1 and 4 months after bone marrow aspiration. Placebo will be administered in this group 6 months after the first injection. Patients of control group will receive placebo 1 and 4 months after bone marrow aspiration. They all receive cell injection 6 months after first placebo injection. Follow up visit will occur at 2 and 6 weeks, and 3 and 6 months after the first injection. Radiological exams will be performed before and 6 months after the first injection by MRI. Clinical quantitative assessment will measure joint function by the WOMAC index and pain by the visual analogue scale.
