Abstract
We prospectively studied 15 proximal tibial and 30 distal femoral fractures treated with the Less Invasive Stabilisation System for periarticular fractures about the knee.
Of these 45 fractures, one patient returned to Russia and was thus lost to follow up. The mean age of the remaining patients was 64.4 years (range 15–94 years). There were 26 females and 13 males. All fractures were classified according to the AO classification.
We found the use of temporary external fixation and mobile radiolucent wedge leg supports very helpful during surgery for these cases. We developed an increasingly aggressive postoperative mobilisation regime with increased experience of using this fixation technique.
Functional assessment was performed using the Schatzker and Lambert scores. The average time to union was 14.78 weeks (range 10– 28 weeks). 43 fractures have united with one fracture showing signs of delayed union. There were two implant failures, two deep vein thrombosis and two compartment syndromes. Five patients died of unrelated causes and without problems relating to their fracture.
We conclude that the Less Invasive Stabilisation System is a satisfactory method of treating these complex and difficult fractures about the knee with a high rate of union and good functional outcome.
