Abstract:

BACKGROUND: Fractures around the knee have been frequently treated by traditional femoral or tibial plate, external fixator or intramedullary nail fixation. But there are many defects, such as extensive soft tissue stripping around fracture fragments, serious breakdown of the local blood supply, increased risks for infection, delayed union, even nonunion.
OBJECTIVE: To explore the surgical indications, methods and effects of the Liss Invasive Stabilization System (LISS) for fractures around the knee.
METHODS: A total of 24 cases of complex fractures around the knee were selected, including 17 males and 7 females, aged 42 years (18-60 years). They were treated using LISS fixation system based on CT three-dimensional reconstruction. All the operations were performed following AO’s standard operating procedures. After the surgery, the patients were followed-up every week in the first 4 weeks, and then followed-up once a month. Hospital for special surgery knee score (HSS) was used to evaluate the treatment effect.
RESULTS AND CONCLUSION: All patients were followed up for 6-24 months. Fracture healed with no occurrence of nonunion. HSS scores revealed 18 cases of excellent, 4 good, 1 fair and 1 poor, resulting in excellent and good rate of 91.67%. The outcome of using Liss fixation system for treatment of fractures around the knee was satisfactory. The soft tissue injury and the disturbance of the local micro-environment are small. It can maximize the protection of local blood supply of fracture, with low infection, high reliability and early active exercise.
