Hypothesis
Can high molecular weight hyaluronan (HA) be safely delivered during arthroscopic debridement of the osteoarthritic knee?
Conclusion
The study found that delivering high molecular weight hyaluronan during arthroscopic debridement is safe and effective in reducing pain and improving function in patients with knee osteoarthritis.
Supporting Evidence
- All thirty arthroscopy procedures were performed without any intra-operative complications.
- Pre-operative WOMAC pain scores improved significantly at 6 weeks and 6 months post-op.
- Patients in the bottom 25th percentile of SF-36 scores showed significant improvement after treatment.
Takeaway
Doctors can safely inject a special gel into the knee during surgery to help people with arthritis feel less pain and move better.
Methodology
Thirty patients underwent arthroscopic debridement and received 6 ml of hyaluronic acid, evaluated preoperatively and at 6 weeks, 3 months, and 6 months post-op.
Potential Biases
Potential bias due to lack of control group and patient selection differences compared to historical controls.
Limitations
The study is a case series with a small sample size and no control group, limiting the generalizability of the results.
Participant Demographics
Nineteen males and eleven females, average age of 46 years, with knee osteoarthritis.
