Body mass index changes after unicompartmental knee arthroplasty do not adversely influence patient outcomes.
The objective of this study is to evaluate the prevalence of patients who lost or gained weight following unicompartmental knee arthroplasty (UKA), the effect of post-operative body mass index (BMI) changes on functional outcomes and quality of life (QoL), and predictive factors associated with BMI changes. ⋯ Level III.

Review Comparative StudyLarger range of motion and increased return to activity, but higher revision rates following unicompartmental versus total knee arthroplasty in patients under 65: a systematic review.
Due to the lack of comparative studies, a systematic review was conducted to determine revision rates of unicompartmental and total knee arthroplasty (UKA and TKA), and compare functional outcomes, range of motion and activity scores in patients less than 65 years of age. ⋯ IV.

Neutral alignment leads to higher knee society scores after total knee arthroplasty in preoperatively non-varus patients: a prospective clinical study using 3D-CT.
The optimal coronal alignment is still under debate. However, in most of the studies, alignment was only assessed using radiographs, which are not accurate enough for assessment of tibial and femoral TKA position. The primary purpose of this study was to assess the relationship between coronal TKA alignment using 3D-reconstructed CTs and clinical outcome in patients with preoperative varus in comparison with patients with natural or valgus deformity. It was the hypothesis that neutral limb alignment shows a better outcome after TKA. ⋯ Diagnostic study, Level II.

Higher physical activity and lower pain levels before surgery predict non-improvement of knee pain 1 year after TKA.
The purpose of this study was to describe patterns of pain during the first year following total knee arthroplasty (TKA) and evaluate pre- and postoperative factors associated with pain and patient satisfaction at 1 year. It was hypothesized that more severe preoperative pain would be associated with more residual pain and lower patient satisfaction 1 year after surgery. ⋯ Prognostic study, Level II.

Increased in vivo patellofemoral loading after total knee arthroplasty in resurfaced patellae.
The primary purpose of the study was to investigate if and how patellar bone tracer uptake (BTU) distribution in SPECT/CT is influenced by patellar resurfacing and the position of femoral and tibial TKA component position. ⋯ Based on the findings of the present study, patellar resurfacing is related to significantly higher BTU in the anterior parts of the patella and lower clinical outcomes. In light of these results, routine patellar resurfacing as part of a primary TKA might be reevaluated. SPECT/CT enables a precise localization of the BTU and might be considered as the ideal imaging modality for evaluation and investigate of patellofemoral disorders after TKA.
