Abstract

An alignment device to align femoral and tibial bones at a knee joint is disclosed. It comprises a femoral arm portion 101 and a tibial arm portion 103, which is connected to the femoral arm portion 101 by an intermediate section 105. The intermediate section 105 is perpendicular to both femoral and tibial arm portions 101, 103. The femoral and tibial arm portions 101, 103 subtend a fixed angle in the range 4-6° (Shown in Figure 1b). In a preferred embodiment, an adjustable arm 301 is slidably mounted on the intermediate section 105. Preferably, the adjustable arm 301 includes a body portion 303 which engages with the intermediate section 105 and an elongate arm 305 which engages with the knee joint. Optionally, a long axis of the elongate arm 305 is in a plane parallel to the plane of the long axis of the femoral or tibial arm portions 101, 103 and in a plane perpendicular to the plane of the long axis of the intermediate section 105.
