Total knee arthroplasty with patient-specific instruments improves function and restores limb alignment in patients with extra-articular deformity.
BACKGROUND Restoring function and alignment when treating knee arthritis with a total knee arthroplasty (TKA) in patients who have an extra-articular deformity (EAD) from a malunion or with retained femoral hardware is a challenge. The normal anatomical landmarks are hard to find and difficult to use to obtain correct alignment. The procedure will be further challenged by angular deformity of t...
متن کاملAlignment 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 کاملDoes Postoperative Mechanical Axis Alignment Have an Effect on Clinical Outcome of Primary Total Knee Arthroplasty? A Retrospective Cohort Study
Background There is an ongoing debate whether patients with constitutional varus should be restored to neutral mechanical alignment following total knee arthroplasty (TKA). Objective The aim of this retrospective cohort study is to determine whether mild unintentional postoperative varus alignment (3°-6°) influences TKA outcome in patients with and without preoperative varus alignment due to ...

متن کاملClinical relevance of persistent postoperative pain after total hip replacement – a prospective observational cohort study
PURPOSE The development of persistent postoperative pain may occur following surgery, including total hip replacement. Yet, the prevalence may depend on the definition of persistent pain. This observational cohort study explored whether the prevalence of persistent pain after total hip replacement differs depending on the definition of persistent pain and evaluated the impact of ongoing pain on...
