Inter-assay variability in the measurement of urinary C-terminal cross-linked telopeptide of type II collagen following anterior cruciate ligament reconstruction.

Objective: To compare urinary C-terminal cross-linked telopeptide of type II collagen (u-CTX-II) concentrations and trends as measured by two different commercially available enzyme-linked immunosorbent assays (ELISA) in a cohort of patients in the first year following anterior cruciate ligament (ACL) reconstruction.

Design: 22 ACL-injured patients undergoing reconstructive surgery (mean age 25.2 (SD 8.

[Recommendations for assessment of disability in private accident insurance-Interdisciplinary consensus-Status September 2024 : Recommended for use by the Specialist Society of Interdisciplinary Medical Expert Opinion (FGIMB) on 6 October 2023].

The centerpiece in private accident insurance is the compensation in cases of disability, which must be determined by a physician within a certain time limit. The insurer contract specifies the compensation rate for loss or inability to function. In cases of insurance the medical expert has to refer to generally accepted revised or updated assessment recommendations in order to be able to apply the given framework to the specific individual disability situation of the insured person.

Development and validation of a novel method for assessing physical activity profiles after anterior cruciate ligament reconstruction: The Sports and Physical Activity scale.

Objectives: To describe and evaluate the preliminary validity of a novel scoring system for assessing the physical activity of patients after anterior cruciate ligament (ACL) reconstruction.

Methods: The Sports and Physical Activity (SPA) scale consists of thirty options of sports and physical activities, followed by four frequency options for each option selected. Factors used to develop the scoring system were frequency of participation and intensity of the sports or physical activities.

Responsiveness of the Various Short-Form Versions of the Knee Injury and Osteoarthritis Outcome Score Between 2 and 5 Years After Anterior Cruciate Ligament Reconstruction.

Background: Various short-form versions of the Knee injury and Osteoarthritis Outcome Score (KOOS) have been developed in an attempt to minimize responder burden. However, the responsiveness of these short-form measures in patients who have undergone anterior cruciate ligament (ACL) reconstruction has not been compared at midterm follow-up.

Purpose: To determine the responsiveness of 3 short-form versions of the KOOS (KOOS-12, KOOS-Global, and KOOS-ACL) in patients who have undergone ACL reconstruction.

Effect of Age and Femoral Tunnel Drilling Technique on the Prevalence of Intra-articular Pathology at Both Primary and Revision ACL Reconstruction.

Background: Studies have shown that meniscal and chondral lesions are more common at the time of revision anterior cruciate ligament reconstruction (ACLR) compared with primary surgery; however, few have evaluated the same patients through both primary and revision surgery.

Purpose: To describe the prevalence of meniscal and chondral lesions at the time of primary and subsequent revision ACLR and to determine the effect of age and femoral tunnel drilling technique on the development of intra-articular pathology over time.

Study Design: Case series; Level of evidence, 4.
