The TeMPO trial (treatment of meniscal tears in osteoarthritis): rationale and design features for a four arm randomized controlled clinical trial.

BMC Musculoskelet Disord 2018 Dec 1;19(1):429. Epub 2018 Dec 1.

Orthopaedic and Arthritis Center for Outcomes Research (OrACORe) and Policy and Innovation eValuation in Orthopedic Treatments (PIVOT), Department of Orthopaedic Surgery, Brigham and Women's Hospital, 60 Fenwood Road, BTM 5016, Boston, MA, 02115, USA.

Background: Meniscal tears often accompany knee osteoarthritis, a disabling condition affecting 14 million individuals in the United States. While several randomized controlled trials have compared physical therapy to surgery for individuals with knee pain, meniscal tear, and osteoarthritic changes (determined via radiographs or magnetic resonance imaging), no trial has evaluated the efficacy of physical therapy alone in these subjects.

Methods: The Treatment of Meniscal Tear in Osteoarthritis (TeMPO) Trial is a four-arm multi-center randomized controlled clinical trial designed to establish the comparative efficacy of two in-clinic physical therapy interventions (one focused on strengthening and one containing placebo) and two protocolized home exercise programs.

Editorial Commentary: Fresh-Frozen Meniscal Allografts-Cold Does Not Always Cause Shrinkage.

Arthroscopy 2018 Dec;34(12):3224-3225

Loma Linda, California.

Meniscal allograft transplantation is an effective treatment for the symptomatic, young, active patient with meniscal deficiency. Modern graft-preservation techniques may reduce clinical sequelae of meniscal shrinkage after transplantation. We prefer fresh-frozen nonirradiated allografts because of easier processing, lower immunogenicity, and lower cost, and on the basis of a 2-decade clinical experience with fresh-frozen meniscal allograft transplantations, we are pleased with our survivorship results.

Possible reparative effect of low-intensity pulsed ultrasound (LIPUS) on injured meniscus.

J Cell Commun Signal 2018 Nov 20. Epub 2018 Nov 20.

Advanced Research Center for Oral and Craniofacial Sciences (ARCOCS), Okayama University Dental School/Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, 2-5-1 Shikata-cho, Kita-ku, Okayama, 700-8525, Japan.

Menisci are a pair of crescent-shaped fibrocartilages, particularly of which their inner region of meniscus is an avascular tissue. It has characteristics similar to those of articular cartilage, and hence is inferior in healing. We previously reported that low-intensity pulsed ultrasound (LIPUS) treatment stimulates the production of CCN2/CTGF, a protein involved in repairing articular cartilage, and the gene expression of major cartilage matrices such as type II collagen and aggrecan in cultured chondrocytes.

Surgical Feasibility of a One-Stage Cell-Based Arthroscopic Procedure for Meniscus Regeneration.

Tissue Eng Part C Methods 2018 Nov 6. Epub 2018 Nov 6.

University Medical Center Utrecht, Orthopaedics Department, Utrecht, Netherlands.

Purpose: To test the technical aspects and feasibility of seeding a combination of meniscus cells isolated from a rapid digestion protocol and mesenchymal stromal cells (MSCs) (20: 80 ratio) into a meniscus scaffold for the development of a one-stage arthroscopic procedure for meniscus regeneration.

Methods: A cadaveric study was performed using nine fresh frozen human cadaveric knee joints. Two different arthroscopic cell-seeding methods were applied to the Collagen Meniscus Implant (CMI®) as carrier scaffold: either 1) seeding before arthroscopic surgical implantation of the scaffold, or 2) after implantation of the scaffold.

SWINE MENISCUS: ARE FEMORAL-TIBIAL SURFACES PROPERLY TUNED TO BEAR THE FORCES EXERTED ON THE TISSUE?

Tissue Eng Part A 2018 Nov 6. Epub 2018 Nov 6.

Università degli Studi di Milano, Department of Health, Animal Science and Food Safety, Milan, Italy ;

Menisci are subjected to different pathologies that affected the knee proper functions and biology. Over the years, different techniques were tried to repair meniscus injury, and, when the reparation was not possible, to replace or regenerate it. These techniques still present a lack of controlled and independent clinical studies that not allow identifying their effective failure rate. Read More

Meniscus Repair and Replacement.

Sports Med Arthrosc Rev 2018 Dec;26(4):160-164

Department of Orthopedics, University of Rochester School of Medicine and Dentistry, Rochester, NY.

The importance of preserving the function of the meniscus is seen with renewed interest. There has been an evolution of arthroscopic meniscus repair from inside-out, outside-in, meniscal fixators, to all-inside suturing techniques. Tear patterns once ignored or thought to be irreparable, such as root tears and horizontal cleavage tears, have recently been undergoing repair with promising results. Read More

There Are No Kinematic Differences Between Inframeniscal and Suprameniscal Anterolateral Ligament Injury in the Anterior Cruciate Ligament-Deficient Knee.

Am J Sports Med 2018 Dec 2;46(14):3391-3399. Epub 2018 Nov 2.

Fowler Kennedy Sports Medicine Clinic/Department of Surgery, Western University, London, Ontario, Canada.

Background:: Previous research demonstrated that the attachment of the anterolateral ligament (ALL) to the lateral meniscus is stiffer and stronger in its tibial attachment than its femoral attachment. How this relates to anterolateral knee stability and lateral meniscal function is unknown.

Hypothesis/purpose:: The hypothesis was that the ALL acts as a peripheral anchor to the lateral meniscus, aiding in anterolateral rotatory stability, and that the inframeniscal fibers of the ALL will provide greater anterolateral rotatory stability because of their greater tensile properties.

Nearly 90% participation in sports activity 12 years after non-surgical management for anterior cruciate ligament injury relates to physical outcome measures.

Knee Surg Sports Traumatol Arthrosc 2018 Nov 1. Epub 2018 Nov 1.

Private Practice, Nambour, Australia.

Purpose: Traditionally reconstructive surgery is recommended for patients planning to return to sport (RTS), especially to pivoting sports after anterior cruciate (ACL) rupture. Recent trends focus on delaying or avoiding surgery as some studies have found similar rates of RTS following both surgical and conservative management. This study aimed to establish long-term RTS levels in ACL-ruptured individuals treated conservatively, and to investigate the relationship between outcome measures and RTS, in particular, pivoting sports.

Safety, Feasibility, and Radiographic Outcomes of the Anterior Meniscal Takedown Technique to Approach Chondral Defects on the Tibia and Posterior Femoral Condyle: A Matched Control Study.

Cartilage 2018 Oct 31:1947603518809409. Epub 2018 Oct 31.

1 Cartilage Repair Center, Brigham and Women's Hospital, Harvard Medical School, Boston, MA, USA.

Objective: Takedown of the anterior meniscus to facilitate exposure of the cartilage defects located on the tibial plateau and/or posterior femoral condyle with subsequent reattachment is being performed clinically; however, clinical evidence is lacking to support the safety of this technique. The aim of this study was therefore to investigate whether meniscal extrusion develops after patients undergo meniscus takedown and transosseous refixation during autologous chondrocyte implantation (ACI).

Design: We analyzed data from 124 patients with a mean follow-up of 6. Read More
