Can KOOS-PS be replaced with a simple anchor question in patients after total knee arthroplasty?: an agreement study of 2,478 primary surgeries.

Background And Purpose:  Physical function and pain are the most important outcomes following total knee arthroplasty (TKA). These can be evaluated by patient-reported outcome measures (PROMs), or by an anchor question. The primary aim of the study was to evaluate whether a simple anchor question can replace KOOS-PS in assessing postoperative knee function until 1-year follow-up, evaluated by analyzing the agreement between the 2 methods using the diagnostic odds ratio (DOR).

Patient-reported outcomes the first thirty days after fast-track primary total hip arthroplasty. A prospective cohort study using a web-based registration tool for postoperative follow-up.

Introduction: The documentation on patient reported outcomes the first weeks at home following total hip arthroplasty (THA) is sparse. Length of hospital stay after THA is substantially reduced. Therefore, knowledge on whether patients are managing their own postoperative rehabilitation early after discharge is important, in order to give the patients realistic preoperative information, to modify expectations and enable patients to monitor their own rehabilitation process.

The extent of first-time THA revision is not associated with patient-reported outcomes at 1-year follow-up: a study of 426 aseptic revisions.

Background And Purpose: Studies evaluating pain and patient-reported outcome measures (PROMs) related to type of revision total hip arthroplasty (rTHA) are sparse. Our aim was to compare pain, physical function, quality of life, and patient satisfaction among different types of aseptic rTHA at 1-year follow-up.

Patients And Methods: We performed a retrospective study from an institutional registry with 426 primary THAs scheduled for rTHA in a fast-track setting between 2012 and 2021.

Physical activity in the first postoperative week in 132 knee arthroplasty patients randomized to 3 different analgesic regimens.

Background: The aim of this study was to investigate whether objectively recorded physical activity in the first week after surgery in total knee arthroplasty patients differed between patients allocated to 3 different analgesic regimens.

Methods: A total of 132 total knee arthroplasty patients wore activity monitors 24 hours a day from day 1 after surgery for 6 consecutive days. The time mobilized (stepping/standing) and the number of steps were recorded.
