We performed a CT-based computer simulation study
to determine how the relationship between any inbuilt posterior
slope in the proximal tibial osteotomy and cutting jig rotational
orientation errors affect tibial component alignment in total knee
replacement. Four different posterior slopes (3°, 5°, 7° and 10°),
each with a rotational error of 5°, 10°, 15°, 20°, 25° or 30°, were
simulated. Tibial cutting block malalignment of 20° of external
rotation can produce varus malalignment of 2.4° and 3.5° with a
7° and a 10° sloped cutting jig, respectively. Care must be taken in
orientating the cutting jig in the sagittal plane when making a
posterior sloped proximal tibial osteotomy in

In posterior stabilised total knee replacement
(TKR) a larger femoral component is sometimes selected to manage the
increased flexion gap caused by resection of the posterior cruciate
ligament. However, concerns remain regarding the adverse effect
of the increased anteroposterior dimensions of the femoral component
on the patellofemoral (PF) joint. Meanwhile, the gender-specific
femoral component has a narrower and thinner anterior flange and
is expected to reduce the PF contact force. PF contact forces were
measured at 90°, 120°, 130° and 140° of flexion using the NexGen

We undertook a prospective, randomised study in order to evaluate the efficacy of clamping the drains after intra-articular injection of saline with 1:500 000 adrenaline compared with post-operative blood salvage in reducing blood loss in 212
We analysed the serum C-reactive protein level, synovial fluid obtained by joint aspiration and five synovial biopsies from 145 knee replacements prior to revision to assess the value of these parameters in diagnosing late peri-prosthetic infection. Five further synovial biopsies were used for histological analysis. Samples were also obtained during the revision and incubated and analysed in an identical manner for 14 days. A total of 40
