Enhancing meniscal repair with tough adhesive puncture sealing (TAPS) suture: A proof-of-concept study on bovine cadaveric knees.

Purpose: The objective was to use cyclic tensile loading to compare the gap formation at suture site of three different suture materials to repair bovine radial meniscal tears: (1) polyglactin sutures, (2) tough adhesive puncture sealing (TAPS) sutures and (3) ultra-high molecular weight polyethylene (UHMWPE) sutures.

Methods: Twelve ex vivo bovine knees were dissected to retrieve the menisci. Complete radial tears were performed on 24 menisci, which were then separated into three groups and repaired using either pristine 2-0 polyglactin sutures, TAPS sutures (2-0 polyglactin sutures coated with adhesive chitosan/alginate hydrogels) or 2-0 UHMWPE sutures with a single stitch.

Medial orientation of the trochlear groove is a strong indicator of high-grade trochlear dysplasia.

Purpose: The objective is to evaluate the orientation of the trochlear groove in patients with objective patellar instability (OPI) compared to a control group. The hypothesis is that the trochlear groove angle (TGA) is correlated with the severity of the trochlear dysplasia.

Methods: From 2019 to 2023, magnetic resonance imaging of 82 knees with OPI were compared with 82 control knees.

Emerging biologic augmentation strategies for meniscal repair: a systematic review.

Background: Meniscal repair should be the gold standard. However, the meniscus is poorly vascularized and even an excellent meniscus repair may not heal. Therefore, numerous studies and systematic reviews have been carried out on platelet-rich plasma (PRP), mesenchymal stem cells (MSCs) and fibrin clots for meniscal augmentation, but the results remain controversial.

Animal models used in meniscal repair research from to : A systematic review.

This systematic review, registered with Prospero, aims to identify an optimal animal model for meniscus repair research, moving from ex vivo experimentation to in vivo studies. Data sources included PubMed, Medline, all Evidence-Based Medicine Reviews, Web of Science, and Embase searched in March 2023. Studies were screened using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

Impact of tourniquet use in total knee arthroplasty on functional recovery and postoperative pain: a prospective study.

Background: Tourniquet use during total knee arthroplasty (TKA) remains controversial. The purpose of this study is to determine the impact of tourniquet use only during cementation compared with its use throughout the entire surgery concerning early outcomes in functional recovery, pain, quadriceps function, and rehabilitation.

Methods: Between November 2019 and March 2020, 118 patients were enrolled in this study, with 59 patients undergoing TKA with a tourniquet during the entire surgery (group 1) and 59 patients with a tourniquet only during cementation (group 2).

Tough gel adhesive is an effective method for meniscal repair in a bovine cadaveric study.

Purpose: To test tough gel adhesives to repair meniscus tears under relevant loading conditions and determine if they have adequate biomechanical properties to repair meniscus tears in a bovine cadaveric study.

Methods: Cyclic compression tests on 24 dissected bovine knees were performed. The tough gel adhesive was used either as an adhesive patch or as a coating bonded onto commercially available surgical sutures.

Modification of the properties of a suture thread with a tough gel coating: A baseline ex-vivo study.

The mechanical properties of sutures are important for wound closure and meniscus repair. A tough gel coating technology has been developed to modify and functionalize sutures, but its effects on suture degradation remain unexplored. Our aim is to investigate how a tough gel coating mediates the properties of the suture.

Osteonecrosis of the trapezium: a case report and review of the literature.

We describe the case of a 58-year-old woman with AVN of the left trapezium which was treated surgically. This paper aims to review the etiologies leading to the pathology and the different therapeutic options. Avascular necrosis (AVN) of the carpal bones most commonly involves the lunate and the scaphoid .

Knee mega-prosthesis in the management of complex knee fracture of the elderly : a case series and review of the literature.

The management of complicated distal femur fractures (DFF) of the elderly continues to pose a challenge. Knee mega-prosthesis are mostly used for Total knee arthroplasty revision and tumor resection surgery but they can be used for the treatment of complex knee fractures. The purpose of the present study is to examine the short- to mid- term outcomes of their use for complex DFF of the elderly.

Orthopaedic support with 3D printing in children : marketing effect or solution of the future?

In pediatric orthopaedics, the immobilization of a limb is traditionally done by a cast. The emergence of 3D technologies allows us to produce restraints specific to the anatomical characteristics of the patient. This paper aims to determine the feasibility of the process of developing these restraints.

Gallbladder torsion: a cholecystectomy that cannot be delayed.

Gallbladder torsion is a rare entity, where the gallbladder twisted around its mesentery. Unfortunately, the diagnosis is rarely done preoperatively. This paper aims, through a case report, to describe the risk factors and the radiological criteria used to diagnose gallbladder torsion, in order to avoid a rapidly unfavourable evolution and the need to proceed to emergency cholecystectomy.
