FUTURE DIRECTION
Knee osteoarthritis is a chronic, degenerative disease that indiscriminately affects all races, ages and genders
Current estimates indicate that by 2030, 67 million Americans will suffer from knee osteoarthritis
The treatment option for knee osteoarthritis is total knee replacement surgery, which carries significant risks for complications
Recent research has proposed the use of mesenchymal stem cells as a non-operative treatment modality for knee osteoarthritis
A standard protocol for mesenchymal stem cell retrieval, implantation and follow-up procedure must be established
Large scale studies must be conducted to determine the long term safety and efficacy of mesenchymal stem cell use for the treatment of knee osteoarthritis before the procedure becomes standard practice
NURSING IMPLICATIONS
Nurses can educate patients on alternative treatment options available for knee osteoarthritis; thus, opening the opportunity to enroll patients into active clinical trials
Nurses must be able to recognize and advocate for patients that would benefit from alternative treatments like mesenchymal stem cell injections before their condition progresses significantly enough that total knee replacement is inevitable
Nurses can use their advocacy skills to improve and change health policy, thereby influencing the way the government makes health care decisions and allocates funding for research
PURPOSE
Investigate the safety and efficacy of mesenchymal stem cell injections as a treatment modality for patients with osteoarthritis
Evaluate patient outcomes when using mesenchymal stem cell injections as treatment for knee cartilage repair
RESULTS
Mesenchymal stem cells can effectively regenerate cartilage by self-renewing and differentiating into chondrocytes, adipocytes, and osteocytes
Studies in the clinical phase have reported increased cartilage growth, better joint function and less pain for clients treated with mesenchymal stem cell injections
Selecting the appropriate mesenchymal stem cell retrieval and application method can lead to a stronger therapeutic response
Pain after the procedure was the most common adverse effect reported post mesenchymal stem cell injection
Patients receiving bone marrow concentrate reported the least adverse effects
Results in the pre-clinical and clinical phase have demonstrated the efficacy and safety of mesenchymal stem cell use for the treatment of knee osteoarthritis
RESEARCH QUESTIONS
1. Have clinical trials been conducted using mesenchymal stem cells as a treatment modality for knee cartilage repair in patients with osteoarthritis?
2. What are the risks of injecting mesenchymal stem cells into damaged knee cartilage?
3. What are the reported benefits stated by clients who have undergone mesenchymal stem cell injections?

CONCLUSION
Knee osteoarthritis is a degenerative disease that causes a myriad of symptoms including disability and persistent pain
Presently, the treatment of choice for chronic knee osteoarthritis is total knee replacement surgery
The findings of this literature review show regenerative medicine is a safe and effective treatment modality for joint preservation and restoration in knee osteoarthritis
