Local Infiltration Analgesia Versus Adductor Canal Block for Managing Pain After Anterior Cruciate Ligament Reconstruction: A Systematic Review and Meta-analysis.

Background: Adductor canal block (ACB) and local infiltration analgesia (LIA) are frequently used to manage pain in patients after anterior cruciate ligament reconstruction (ACLR).

Purpose: To compare the difference in pain scores and opioid consumption between ACB and LIA for ancillary pain management in patients after ACLR.

Study Design: Systematic review; Level of evidence, 3.

Accuracy of a Patient-Specific Total Ankle Arthroplasty Instrumentation.

Background: Total ankle arthroplasty (TAA) is a preferred surgical option for end-stage ankle osteoarthritis; however, it is a demanding procedure with a higher historical rate of revision compared with ankle fusion. Patient-specific instrumentation (PSI) has been introduced to optimize prosthesis alignment and theoretically overall improve TAA outcomes. The goal of this study is to report on the experience and surgical outcomes of one implant with specific evaluation of the accuracy and reproducibility of the system with respect to prosthesis alignment and prediction of implant size.

Using a national surgical database to predict complications following posterior lumbar surgery and comparing the area under the curve and F1-score for the assessment of prognostic capability.

Background: With spinal surgery rates increasing in North America, models that are able to accurately predict which patients are at greater risk of developing complications are highly warranted. However, the previously published methods which have used large, multi-centre databases to develop their prediction models have relied on the receiver operator characteristics curve with the associated area under the curve (AUC) to assess their model's performance. Recently, it has been found that a precision-recall curve with the associated F1-score could provide a more realistic analysis for these models.
