The morphometry of the distal femur was largely studied to improve
bone-implant fit in total knee arthroplasty (TKA), but little is
known about the asymmetry of the posterior condyles. This study
aimed to investigate the dimensions of the posterior condyles and
the influence of externally rotating the femoral component on potential prosthetic
overhang or under-coverage. We analysed the shape of 110 arthritic knees at the time of primary
TKA using pre-operative CT scans. The height and width of each condyle
were measured at the posterior femoral cut in neutral position,
and in 3º and 5º of external rotation, using both central and medial
referencing systems. We compared the morphological characteristics
with those of 14 TKA models.Aims
Patients and Methods
There is growing evidence in literature that meniscal allograft transplantation performed with the right indications results in significant pain relief and functional improvement of the involved joint. Long-term data on clinical and radiological outcome are however scarce. We evaluated 89 transplants (53 lateral and 36 medial) in 87 patients. Mean time of follow-up was 15,5 ± 2,85 years (range 9,9–20,4), mean age at surgery was 35,2 years (range 22–50). Clinically, the patients were evaluated using a KOOS, SF-36, HSS, VAS, Tegner and Lysholm score. HSS scores were compared to pre-operative and mid-term follow-up data. Each patient received radiographs (AP, profile and Rosenberg view). Radiological outcome parameters were joint space width narrowing and Fairbank changes and were scored according to IKDC. Failures were defined as patients who were converted to an arthroplasty.Background
