Abstract:Objective To evaluate the clinical efficacy of arthroscopic treatment of tibial intercondylar eminence fracture with Kirschner wire suture tension band technique.Method Thirteen patients with tibial intercondylar protuberance fracture from October 2017 to September 2019 were selected as research objects. All of them were fixed by Kirschner wire suture tension band under arthroscopy. There were 7 male patients and 6 female patients with an average age of (28.92 ± 10.71) years old (range, 13 ~ 48 years). The results of Lachman and anterior drawer test were both positive. All the patients were evaluated with Lysholm score, International Knee Documentation Committee (IKDC) score and X-ray examination before and after operation.Results The mean duration of follow-up was (10.31 ± 1.89) months (range, 6 ~ 12 months) in all the patients. Postoperative X-ray showed good reduction of all the fractures, and the fractures were healed in (3.69 ± 0.48) months on average (3 ~ 4 months). Infection, knee dysfunction, neurovascular injury were not found after surgery. All these cases were examined normal range of motion, negative Lachman test and anterior draw test at the end of the follow-up. Lysholm scores increased from (36.46 ± 4.89) preoperatively to (94.85 ± 1.82) at the last follow-up (t = -46.77, P = 0.000), the IKDC score increased from (47.19 ± 4.17) preoperatively to (87.92 ± 3.79) (t = -40.72, P = 0.000), there were significant difference before and after operation.Conclusion The arthroscopic treatment of tibial intercondylar eminence fracture with Kirschner wire suture tension band technique has the advantages of minimal invasive, quickly postoperative recovery, simple operation, reliable fixation, low cost of internal fixation consumables, and satisfactory curative effect.
