AI Article Synopsis
- Developed a 5-grade photographic scale to assess neck laxity using morphed images based on real photographs.
- Images were evaluated by 6 physicians over 2 rounds to ensure reliability.
- The scale showed high inter-rater (>.85) and intra-rater (0.69-0.87) agreement, confirming its validity and reliability for use.
Article Abstract
Objective: To describe the development and validation of the 5-grade photographic IBSA Neck Laxity Scale.
Methods: The scale was developed from 2 real images, which led to the creation of 5 morphed images, representing different degrees of severity of laxity of the neck. For validation, a set of 50 images (25 real and 25 morphed) was created and sent for evaluation to 6 trained raters (physicians) in 2 rounds, 1 month apart. Raters had to assess each image according to the 5-image scale. Inter-rater and intra-rater reliability in both rounds was evaluated.
Results: As to intra-rater reliability, single rater kappa scores between 0.69 and 0.87, and a global kappa score of 0.78 were observed. Inter-rater agreement was measured by means of the intra-class correlation coefficient and scores higher than 0.85 were reported, indicating excellent reliability.
Conclusion: IBSA Neck Laxity Scale is a validated and reliable scale.

Combining an internal tension relieving technique with anterior cruciate ligament reconstruction (ACLR) reduces graft failure rate and improves functional outcomes: a systematic review and meta-analysis.

Department of Orthopaedic Surgery, The Fifth Hospital of Wuhan, Wuhan, Hubei, 430000, China.
Purpose: Graft rupture is a significant cause of graft failure in anterior cruciate ligament reconstruction (ACLR). To address this issue, clinicians have combined the internal tension relieving technique (ITRT) with ACLR to improve graft stiffness, aiming to reduce the risk of graft failure. The purpose of this study is to compare the graft failure rates and clinical functional outcomes between ITRT-assisted ACLR and conventional ACLR.

Background: The use of non-ablative fractionated lasers for skin rejuvenation has been proven to be effective in improving skin texture, and has become popular due to minimal wounding, significantly shorter recovery times and decreased adverse effects.
Objective: To retrospectively analyze improvement in skin texture in healthy women aged over 18 years with Fitzpatrick skin type II-IV.
Methods: Participants received 3 facial and/or neck treatments with the 1570-nm fractional scanning diode laser at one-month intervals.

Department of Dermatology, School of Medicine, Halic University, Istanbul, Turkey.
Background: The multifactorial nature of aging necessitates a comprehensive assessment addressing contour, volume, and facial laxity, and a holistic treatment plan. We evaluated combined use of HArmonyCa with HA fillers to improve laxity and overall aesthetic outcomes. A detailed guide is also presented regarding facial shapes, special areas, and volume needs.

Background: For complete disruption of the posterolateral corner (PLC) structures, operative treatment is most commonly advocated, as nonoperative treatment has higher rates of persistent lateral laxity and posttraumatic arthritis. Some studies have shown that acute direct repair results in revision rates upwards of 37% to 40% compared with 6% to 9% for initial reconstruction. In a recent study assessing the outcomes of acute repair of PLC avulsion injuries with 2 to 7 years of follow-up, patients with adequate tissue were shown to have a much lower failure rate than previously documented.

Introduction: The aging neck is a prevalent aesthetic concern, with over 160,000 neck procedures performed in 2020. It is characterized by increased soft tissue laxity and displacement of cervical structures. While nonsurgical interventions like cryoablation and laser resurfacing show promise, their variable responses highlight the necessity for surgical solutions.
