Comparative Study
The predictors of outcome in total knee arthroplasty for post-traumatic arthritis.
The outcomes of total knee arthroplasty (TKA) for post-traumatic arthritis are less reliable than for idiopathic osteoarthritis. These patients tend to be younger, present with varying degrees of deformity, and often have a history of prior surgery, resulting in a wide spectrum of pathology. We hypothesized that preoperative variables, in particular the location of deformity, would predict pain and functional outcomes. ⋯ IV-Retrospective Case Series.

Is the posterior cruciate ligament destabilized after the tibial cut in a cruciate retaining total knee replacement? An anatomical study.
Cruciate retaining total knee replacement has been shown to effectively improve pain and quality of life. Successful outcomes depend on many factors, including the maintenance of a competent posterior cruciate ligament. This study sought to anatomically analyze the percentage of PCL injured during a full transverse, tibial cut, thus altering normal function. ⋯ II.

Comparative Study
Osteochondral scaffold reconstruction for complex knee lesions: a comparative evaluation.
The primary aim of the present study is to evaluate the results obtained in challenging knee lesions with the implant of an osteochondral scaffold and concomitant treatment of all comorbidities. The secondary aim is to compare the results obtained with those found when a chondral scaffold was applied. ⋯ Comparative study.

Comparative Study
Patellar resurfacing versus no resurfacing in two-stage revision of infected total knee arthroplasty.
Cartilage debridement and staged reimplantation are the most common treatments for infected total knee arthroplasty (TKA). Very few studies have focused on the management of primarily non-resurfaced patellae in infected TKA. The purpose of this study was to compare the outcomes of patellar resurfacing and non-resurfacing in two-stage revision of infected TKA. ⋯ Level III, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

Comparative Study
Association between long-term quadriceps weakness and early walking muscle co-contraction after total knee arthroplasty.
Quadriceps weakness is one of the primary post-operative impairments that persist long term for patients after total knee arthroplasty (TKA). We hypothesized that early gait muscle recruitment patterns of the quadriceps and hamstrings with diminished knee performance at 3months after surgery would be related to long-term quadriceps strength at 1year after TKA. ⋯ III.
