Single and double bundle posterior cruciate ligament reconstruction yield comparable clinical and functional outcomes: a systematic review and meta-analysis.

Purpose: To perform a systematic review and compare the functional and objective outcomes after single-bundle (SB) vs. double-bundle (DB) posterior cruciate ligament reconstruction (PCLR). Where possible to pool outcomes and arrive at summary estimates of treatment effect for DB PCLR vs.

The Comprehensive Aachen Knee Score: Development and validation of a new patient-reported outcome measure for patellofemoral pathologies.

Background: Existing patient-reported outcome measures (PROMs) that assess knee pain and symptoms show insufficient quality regarding their psychometric properties. We developed and validated a new PROM assessing knee pain and especially patellofemoral pathologies, the COMPrehensive AaChen Knee Score (COMPACK).

Methods: We followed a three-phase process of development and validation.

A meta-analysis of measurement properties of the Western Ontario Meniscal Evaluation Tool (WOMET).

Background: We provide a meta-analysis for clinicians and researchers regarding the psychometric properties of the WOMET as a patient-reported outcome measure (PROM) for patients with meniscal pathologies.

Methods: A comprehensive literature search identified 6 eligible papers evaluating WOMET measurement properties in patients with different meniscal injuries and meniscal treatments following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The quality of the included studies was evaluated using the four-point Consensus-based Standard for the selection of health Measurement Instruments (COSMIN) Checklist for good measurement properties.

Meta-analysis of the validity and reliability of rasterstereographic measurements of spinal posture.

Objective: We provide a meta-analysis for clinicians and researchers regarding reliability and validity of rasterstereographic measurement of the spinal posture.

Method: A comprehensive PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) literature search identified 19 eligible studies evaluating reliability and validity of static rasterstereographic measurements in healthy subjects and patients with different spinal pathologies.

Results: Our meta-analysis suggests that rasterstereography is a reliable and valid instrument to assess spinal posture parameters, especially thoracic kyphosis, lumbar lordosis, and scoliosis, reliability overall effect sizes rs > .

3-Dimensional Cervical Movement Characteristics and the Influence of Thoracic Treatment on a Subgroup of Acute Neck Pain Patients.

Objective: The purpose of this study was to investigate the influence of thoracic high-velocity low-amplitude thrust (HVLAT) manipulation on quantitative and qualitative 3-dimensional cervical spine kinematic patterns in a subgroup of patients with acute neck pain.

Methods: Thirty patients with acute neck pain, aged 20 to 59, received a thoracic HVLAT manipulation. Three-dimensional kinematics of the cervical spine were registered pretreatment and posttreatment using an electromagnetic tracking system.
