The effect of anteroposterior laxity on the range of movement and knee function following a cruciate-retaining total knee replacement

Having demonstrated in Chapter 2 that a fully conforming mobile bearing can minimise polyethylene wear, in this chapter we show that a mobile bearing prosthesis, unconstrained in the sagittal plane, can restore natural mobility and stability. For surgeon readers who are less interested in the theoretical background, it might be advisable to go straight to Chapter 4, Indications, or to start by reading the final section of this chapter, The Loaded Prosthetic Knee. If that proves interesting, the surgeon might attempt The Unloaded Prosthetic Knee. For the more research minded surgeon or engineer, it seems more logical to start with the Unloaded Natural Knee (the longest section of the chapter) and to read from there. The chapter may also be of interest to those surgeons embarking on the use of a bi-cruciate retaining total knee replacement.

The Mean

Summary Purpose Purpose of this retrospective study was to evaluate our own results after total knee replacement in patients with haemophilia. Patients, material, method: 30 patients with haemophilia who underwent total knee replacement between 1987 and 2005 were included. We used the clinical and radiological Knee Society Score. Furthermore, the Petterson and the Arnold and Hilgartner score were applied. Results: The mean age at the time of surgery was 43.2 (27–66). At the time of follow- up examination the mean age was 51.6 (30–82) years. The mean follow-up was 7.1 (2–20) years. Preoperative, he mean Arnold and Hilgartner score was 4.17 (± 0.59) and the mean Petterson-Score was 9 ± 2.29. Compared to the preoperative deficiency in knee function (KSS-Score 88.17 ± 33.58) an improvement with 166.67 (± 22.73) points was seen. 1 patient showed an aseptic loosening after 11 years. Discussion: Total knee replacement in patients with haemophilia improves knee function and quality of life. The results of our study represent results in earlier published studies. Compared to a non-haemo-philic normal population the rate of perioper-ative complications was not increased.
