BACKGROUND: The treatment of degenerative knee osteoarthritis is mainly to relieve pain, restore knee function, improve quality of life, delay knee replacement, and reduce the number of revisions. Knee replacement is currently the most common treatment for this disease, but it costs much, has great trauma and high risk, often results in prosthesis loosening and peripheral infection, and has many adverse reactions. OBJECTIVE: We hypothesize that knee-preserving arthroscopic debridement for treatment of knee degenerative osteoarthritis in the elderly patients costs less, is effective, safe, and reliable. METHODS: A total of 212 elderly patients (knees) with degenerative knee osteoarthritis who receive treatment in the Second Hospital of Chaoyang (Liaoning Province, China) will be included in this study. These patients will be assigned to two groups according to patient's conditions and wishes (n = 106/group). In the control group, intra-articular injection of sodium hyaluronate will be performed, followed by oral administration of non-steroidal anti-inflammatory drugs, conventional physiotherapy, and quadriceps functional exercise. In the arthroscopic debridement group, arthroscopic debridement will be performed followed by oral administration of non-steroidal anti-inflammatory drugs, conventional physiotherapy, and quadriceps functional exercise. All patients will be followed up for 1 week, 1 month, 3 months, 6 months, 1 year, and 2 years. RESULTS AND CONCLUSION: The primary outcome measure is the percentage of the number of patients with Hospital for Special Surgery (HSS) knee score ≥ 85 points at 2 years after surgery, which will be used to evaluate knee function recovery. The secondary outcome measures are the percentage of the number of patients with HSS knee score ≥ 85 points before surgery, 1 week, 1 month, 3 months, 6 months, and 1 year after surgery; HSS score, Visual Analogue Scale (VAS) score, The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), knee range of motion, hospitalization costs, and knee X-ray morphology before surgery, 1 week, 1 month, 3 months, 6 months, 1 year, and 2 years after surgery, medical costs after 2 years of treatment, incidence of adverse reactions at 1 week, 1 month, 3 months, 6 months, 1 year and 2 years after surgery. Findings from this study will reveal whether arthroscopic debridement for the treatment of degenerative knee osteoarthritis in the elderly patients has advantages of less adverse reactions, low treatment costs, and can effectively restore knee function.

Objective:To observe the clinical efficacy of auricular point sticking at different points to relieve the pain in arteriovenous fistula puncture. Methods: A total of 42 patients with arteriovenous fistula were randomized into a Shenmen (TF4) group and an Elbow (SF3) group by the random number table method, with 21 cases in each group. After enrolled into different groups, before the dialysis, patients were given auricular point sticking with Wang Bu Liu Xing ( Semen Vaccariae) seeds at Shenmen (TF4) and Elbow (SF3), respectively. Patients were asked to press the seeds themselves for 2 min each time, four times a day, and an additional 5-15 min before the arteriovenous fistula puncture. Intensive pressing was offered during the puncture, 15-20 presses for each time, and the plasters were changed every 2-3 d. The numerical rating scale (NRS) was used to score the pain level one week before and after auricular point sticking. The NRS score was then compared and analyzed. Results: The intra-group comparison showed that the changes of NRS score in both groups were statistically significant after auricular point sticking (both P＜0.05). After the treatment, there was no significant difference in NRS score between the two groups (P＞0.05). Conclusion: Auricular point sticking at Shenmen (TF4) or Elbow (SF3) can effectively relieve the pain of arteriovenous fistula puncture, and these two points have equivalent analgesic effect.
