Alignment in total knee replacement.
The advent of computer-assisted knee replacement surgery has focused interest on the alignment of the components. However, there is confusion at times between the alignment of the limb as a whole and that of the components. The interaction between them is discussed in this article. Alignment is expressed relative to some reference axis or plane and measurements will vary depending on what is se...
متن کاملCoronal alignment after total knee replacement.
Maquet's line passes from the centre of the femoral head to the centre of the body of the talus. The distance of this line from the centre of the knee on a long-leg radiograph provides the most accurate measure of coronal alignment. Malalignment causes abnormal forces which may lead to loosening after knee replacement. We report a series of 115 Denham knee replacements performed between 1976 an...
متن کاملLimb alignment in computer-assisted minimally-invasive unicompartmental knee replacement.
Twenty patients underwent simultaneous bilateral medial unicompartmental knee arthroplasty. Pre-operative hip-knee-ankle alignment and valgus stress radiographs were used to plan the desired post-operative alignment of the limb in accordance with established principles for unicompartmental arthroplasty. In each patient the planned alignment was the same for both knees. Overall, the mean planned...
متن کاملHow accurate is anatomic limb alignment in predicting mechanical limb alignment after total knee arthroplasty?
BACKGROUND Anatomic limb alignment often differs from mechanical limb alignment after total knee arthroplasty (TKA). We sought to assess the accuracy, specificity, and sensitivity for each of three commonly used ranges for anatomic limb alignment (3-9°, 5-10° and 2-10°) in predicting an acceptable range (neutral ± 3°) for mechanical limb alignment after TKA. We also assessed whether the accurac...
متن کاملMedial Unicompartmental Osteoarthritis (MUO) of the Knee: Unicompartmental Knee Replacement (UKR) or Total Knee Replacement (TKR)
The aim of this review article is to analyze the clinical effectiveness of total knee replacement (TKR) compared to unicompartmental knee replacement (UKR) in patients with medial unicompartmental osteoarthritis (MUO) in terms of survival rates, revision rates and postoperative complications. The search engine was MedLine. The keywords used were: medial knee osteoarthritis. Three thousand and n...
