Abstract

To evaluate the outcome of one stage long stem total knee arthroplasty (TKA) of patients with stress fracture of the proximal tibia of the knee joint.

Record of 15 patients, 14 females and one male who underwent one stage long stem TKAfrom the year January 2008 till December 2014 were reviewed retrospectively. Outcome variable was fracture healing which was seen clinically (pain free and postop ambulation) as well as radiologically (union of three out of four cortices).

Mean age of the patients were 65 years and the mean BMI was 31. Of the 15 knees 13 had varus malalignment and 2 had valgus malalignment. The mean duration of fracture healing was four and a half months and the mean duration of follow-up was 26 months. All the patients were ambulated full weight bearing with walker. One patient had non-union at fracture site which required bone grafting.

Long stem TKA is an effective method of treating tibial stress fractures associated with advance osteoarthritis as it not only restores the normal mechanical alignment but also facilitates fracture healing
