The effect of tuberositas tibia osteotomy on patellofemoral joint pressure: An experimental animal study
Aim: To demonstrate the decrease in patellofemoral pressure with an anterior elevation of tuberositas tibia. Therefore, we have performed Maquet’s Technique to evaluate the patella pressure on femoral trochlea by biomechanically in an animal experiment model.
Methods: This study includes total of 42 knees of 21 New Zealand rabbits. Animals were divided into two groups. The first group including 21 right knees was designated as the control group. In the second group including 21 left knees, anterior elevation of tuberositas tibia (Maquet’s technique) was performed. Pressure measuring film layer “prescala” (Fujifilm, Japan) was placed on the patellofemoral joint under anesthesia in both groups. Mean values of both average and maximal pressure measurements in two groups were compared.
Results: There is a statistically significant difference in between average pressure and maximum pressure in the right and left legs of the rabbits. Average pressure and maximal pressure at rabbit knees performed Maquet’s procedure were significantly lower than knees without Maquet’s procedure.
Conclusion: Anterior elevation of tuberositas tibia is successful in reducing patellofemoral joint pressure which can be used in cases with patellofemoral pain syndrome non-responding to conservative treatment.
