Severe patellofemoral arthritis does not compromise 6-month post-operative range of motion or function following unicondylar knee arthroplasty.
The presence of significant patellofemoral arthritis (PFA) is still considered a contraindication for unicondylar knee arthroplasty (UKA) by many surgeons. The purpose of this study was to determine if the presence of severe PFA at the time of UKA compromised early (< 6 months) post-operative knee range of motion or functional outcomes. ⋯ Patients with severe PFA demonstrate similar clinical improvement following UKA at 6 months as patients with less severe PFA.

The temporal effects of asymptomatic COVID-19 infection on peri-operative complications in patients receiving total joint arthroplasty.
Recent coronavirus disease 2019 (COVID-19) infection may pose increased risk of post-operative complications after total joint arthroplasty (TJA). Current recommendations suggest waiting four-weeks before elective surgery in asymptomatic patients. The purpose of this study was to propensity-score-match patients who had positive COVID-19-test between (1) 0-2 weeks and (2) 2-4 weeks before TJA with a matching group without COVID-19 history to determine rates of complications at 90-days and 1-year post-operatively. ⋯ Asymptomatic patients who test positive for COVID-19 don't have increased risk for post-operative complications after TJA. However, two-fold increased risk in PJI for patients who tested positive for COVID-19 in first 2-weeks cannot be ignored. These results should be taken into consideration when surgeons consider performing TJA. We recommend asymptomatic patients consider waiting two-weeks before TJA to mitigate risk of PJI. Nevertheless, there's reassurance these patients are not at increased total complication risk.

Predictors for infection severity for open tibial fractures: major trauma centre perspective.
Open diaphyseal tibial fractures are the most common long-bone fractures and require a rapid approach to prevent devastating complications. Current literature reports the outcomes of open tibial fractures. However, there is no robust, up-to-date research on the predictive indicators of infection severity in a large open tibial fracture patient cohort. This study investigated the predictive factors of superficial infections and osteomyelitis in open tibial fractures. ⋯ Higher GA classification is a significant risk factor for developing superficial infection and osteomyelitis, with a stronger association with osteomyelitis, especially GA 3C fractures. Predictors for superficial infection included BMI and time to soft tissue closure. Time to definitive fixation, time to soft tissue closure, and wound contamination were associated with osteomyelitis.

Mobile-bearing prosthesis suppresses the postoperative rotational mismatch and improves patient-reported outcome measurements better than fixed-bearing prosthesis: rotational analysis by 3D measurement in total knee arthroplasty.
It is preferable to reduce postoperative excessive rotational mismatch between the femur and tibia that causes poor clinical results following total knee arthroplasty (TKA). The aim of this study is to compare postoperative rotational mismatches and clinical outcomes with mobile- and fixed-bearing prostheses. ⋯ When compared to a fixed-bearing prosthesis, TKA using a mobile-bearing prosthesis could suppress the postoperative rotational mismatch between the femur and tibia that causes poor subjective functional activity score. However, since this study was conducted for PS-TKA, the results might not be applicable to other models.

Tunnel widening after ACL reconstruction with different fixation techniques: aperture fixation with biodegradable interference screws versus all-inside technique with suspensory cortical buttons. 5-year data from a prospective randomized trial.
The aim of the present study was to examine tunnel widening and clinical outcomes after anterior cruciate ligament reconstruction (ACLR) using two different fixation methods: aperture fixation with biodegradable interference screws versus all-inside ACLR with suspensory cortical buttons. ⋯ NCT01755819.
