Authors:
Peter R Kurzweil

Arthroscopy 2019 Feb 22. Epub 2019 Feb 22.

Long Beach, California.

Early-generation meniscal fixators sometimes caused iatrogenic articular cartilage damage. This resulted in injury to the very structure one tries to preserve when repairing a meniscal tear. Advances in suture-based meniscal implants and all-inside suture devices have allowed us to safely repair meniscal tears, even ones thought previously irreparable, and without the need for a secondary incision.

Division of Sports Medicine, Department of Orthopedic Surgery, Boston Children's Hospital, Harvard Medical School, Boston, Massachusetts, USA.

Background: Bucket-handle meniscal tears (BHMTs), which we define as vertical longitudinal tears of the meniscus with displacement of the torn inner fragment toward the intercondylar notch region, are a well-recognized tear pattern. Optimizing the management of BHMTs in younger patients is important, as preserving meniscal tissue may limit future joint degeneration.

Purpose/hypothesis: The purpose of this study was to review the patient demographics, clinical presentation, operative details, outcomes, and risk factors for a reoperation associated with operatively treated BHMTs in a pediatric population. Read More

Anterior cruciate ligament reconstruction with concomitant meniscal surgery: a systematic review and meta-analysis of outcomes.

Knee Surg Sports Traumatol Arthrosc 2019 Feb 4. Epub 2019 Feb 4.

Division of Orthopaedic Surgery, Department of Surgery, McMaster University, Hamilton, ON, Canada.

Purpose: The aim of this review was to compare the clinical outcomes of anterior cruciate ligament reconstruction (ACLR) with either meniscal repair or meniscectomy for concomitant meniscal injury. The primary hypothesis was that short-term clinical outcomes (≤ 2-year follow-up) for ACLR concomitant with either meniscal repair or resection would be similar. The secondary hypothesis was that ACLR with meniscal repair would result in better longer term outcomes compared with meniscal resection. Read More

An Abnormal Tibial Position Is Associated With Alterations in the Meniscal Matrix: A 3-Year Longitudinal Study After Anterior Cruciate Ligament Reconstruction.

Orthop J Sports Med 2019 Jan 10;7(1):2325967118820057. Epub 2019 Jan 10.

Department of Orthopaedic Surgery, University of California, San Francisco, San Francisco, California, USA.

Background: An altered tibial position is still present despite anterior cruciate ligament (ACL) reconstruction. It has been demonstrated that an abnormal tibial position after an ACL injury may play a role in subsequent injuries to the meniscus, which can lead to early cartilage degeneration.

Purpose: To determine changes in both the tibial position and the meniscal matrix present before and after ACL reconstruction as well as to evaluate the association between these 2 variables in ACL-injured knees 3 years after reconstruction. Read More

The Occurrence of Meniscal and Chondral Injury in Two-Stage Revision Anterior Cruciate Ligament Reconstruction: A Consecutive Case Series.

J Knee Surg 2019 Jan 18. Epub 2019 Jan 18.

Focus Clinic Orthopedic Surgery, Haaglanden Medical Center, Den Haag, Zuid-Holland, The Netherlands.

Two-stage revision anterior cruciate ligament (ACL) reconstruction is an effective way to revise suboptimal tunnel-placement allowing for proper graft fixation. However, prolonged increased laxity of the knee may increase the risk of meniscal or chondral injury. It was hypothesized that no additional meniscal or chondral lesions occur in between the two stages of the two-stage revision ACL reconstruction. Read More

Risk Factors for Lateral Meniscus Posterior Root Tears in the Anterior Cruciate Ligament-Injured Knee: An Epidemiological Analysis of 3956 Patients From the SANTI Study Group.

Am J Sports Med 2019 Mar 16;47(3):598-605. Epub 2019 Jan 16.

Centre Orthopédique Santy, FIFA Medical Center of Excellence, Hôpital Privé Jean Mermoz, Groupe Ramsay-Generale de Santé, Lyon, France.

Background:: Lateral meniscus posterior root tears (LMPRTs) result in loss of hoop forces and significant increases in tibiofemoral contact pressures. Preoperative imaging lacks reliability; therefore, holding an appropriate index of suspicion, based on the epidemiology of and risk factors for LMPRT, may reduce the rate of missed diagnoses.

Purpose:: The primary objectives of this study were to evaluate the incidence of and risk factors for lateral meniscus root lesions in a large series of patients undergoing anterior cruciate ligament (ACL) reconstruction. Read More

Editorial Commentary: How to Treat the Overweight Pediatric Patient.

Authors:
Eric C McCarty

Arthroscopy 2019 Jan;35(1):136-137

Boulder, Colorado.

Obese pediatric patients that incur an anterior cruciate ligament tear have an increased risk of an irreparable meniscal tear. Nevertheless, these patients should be treated the same as normal weight patients because they can do very well with standard anterior cruciate ligament reconstruction techniques and appropriate postoperative physical therapy as well as a delayed return to sports of at least 9 months. Obesity is an ever-increasing issue in the United States. Read More
