Cost-Effectiveness Analysis of a Medial Meniscus Replacement Prosthesis for the Treatment of Patients with Medial Compartment Pain in the United Kingdom.

Pharmacoecon Open 2022 May 17. Epub 2022 May 17.

University Hospitals Coventry Warwickshire NHS Trust, Coventry, UK.

Background: The most common intra-articular knee injury is a meniscal tear, which commonly occurs secondary to trauma following twisting or hyperflexion. Treatment options for meniscal tears can either be surgical or non-surgical, and range from rest, exercise, bracing and physical therapy to surgical intervention, including meniscal repair and partial meniscectomy. In patients with persistent pain following loss of meniscus tissue, treatment can include partial replacement or meniscal allograft transplantation. Read More

Isolated meniscus injuries in skeletally immature children and adolescents: state of the art.

J ISAKOS 2022 Feb 11;7(1):19-26. Epub 2022 Jan 11.

Department of Orthopaedic Surgery, Aspetar Orthopaedic and Sports Medicine Hospital, Doha, Qatar. Electronic address:

The prevalence of isolated meniscal injuries in children and adolescents is low; however, we see an increase mainly due to intensified sports-related activities at an early age. A meniscal repair should be attempted whenever possible as children present with increased meniscal healing potential. The diagnosis and management of meniscal tears involve both patient factors and tear characteristics: size, anatomical location and associated injuries. Read More

Meniscus Root Tears: A Clinical Review.

Curr Sports Med Rep 2022 May 1;21(5):155-158. Epub 2022 May 1.

Department of Physical Medicine and Rehabilitation, The Ohio State University, Columbus, OH.

Abstract: Meniscus root tears are important to recognize early given their potentially devastating consequences on joint health. This injury results in the lost ability of the meniscus to transfer axial loads into hoop stress; therefore, it is functionally equivalent to a complete meniscectomy. This causes rapid progression of osteoarthritis and increased need to total knee arthroplasty in a previously healthy joint. Read More

Meniscal repair at the time of primary ACLR does not negatively influence short term knee stability, graft rupture rates, or patient-reported outcome measures: the STABILITY experience.

Knee Surg Sports Traumatol Arthrosc 2022 Apr 22. Epub 2022 Apr 22.

Faculty of Health Sciences, Western University, London, Canada.

Purpose: To assess how meniscal repair and excision impact short term patient-reported outcome measures (PROMs), knee stability, and early graft rupture rates following primary hamstring anterior cruciate ligament reconstruction (ACLR) with or without lateral extra-articular tenodesis (LET) in a group of young active patients where meniscal repair is commonly advocated.

Methods: Six hundred and eighteen patients under 25 years of age at high-risk of graft failure following ACLR were recruited to the Stability 1 study. Multivariable regression models were developed to identify statistically and clinically significant surgical and demographic predictors of Knee Injury and Osteoarthritis Outcome Score (KOOS), International Knee Documentation Committee Subjective Knee Form (IKDC), ACL Quality of Life Questionnaire (ACL-QOL) and Marx Activity Rating Scale (MARS) scores.

No difference in postoperative efficacy and safety between autograft and allograft in anterior cruciate ligament reconstruction: a retrospective cohort study in 112 patients.

Ann Transl Med 2022 Mar;10(6):359

Department of Orthopedics, Shanghai Tenth People's Hospital, School of Medicine, Tongji University, Shanghai, China.

Background: Arthroscopic anterior cruciate ligament reconstruction (ACLR) is the best treatment choice for returning to pre-injury activities following ACL rupture. Although allografts are considered an effective alternative to autografts, there is still controversy regarding the safety and effectiveness of this procedure, especially concerning the risk of postoperative infection and disease transmission. The purpose of this study was to compare the efficacy outcomes and safety between allografts and autografts in primary ACLR. Read More

Biomechanical consequences of anterior root detachment of the lateral meniscus and its reinsertion.

Sci Rep 2022 04 13;12(1):6182. Epub 2022 Apr 13.

Clinical Biomechanics of Andalucia Laboratory, University of Malaga, Malaga, Spain.

Treatment of posterior meniscal roots tears evolved after biomechanical evidence of increased pressures on the tibiofemoral cartilage produced by this lesion and the subsequent accelerated development of arthritis or osteonecrosis observed clinically. However, little is known about the consequences of the detachment of the anterior roots. This in-vitro study analyzes the biomechanical changes in the tibiofemoral joint caused by avulsion of the anterior root of the lateral meniscus. Read More

Quality of life during the wait for ruptured anterior cruciate ligament reconstruction: a randomized controlled trial.

Can J Surg 2022 Mar-Apr;65(2):E269-E274. Epub 2022 Apr 12.

From the Department of Surgery, University of Manitoba, Winnipeg, Man. (Larose, Stranges, MacDonald, Rollins, Leiter, McRae); the Department of Radiology, University of Manitoba, Winnipeg, Man. (Davidson); the Department of Anatomy, University of Manitoba, Winnipeg, Man. (Peeler); the Pan Am Clinic Foundation, Winnipeg, Man. (Leiter, McRae); and the Pan Am Clinic, Winnipeg, Man. (Stranges, Davidson, MacDonald).

Background: There is a lack of prospective evidence to guide surgeons when making recommendations about the appropriate timing of surgical intervention for ruptured anterior cruciate ligament (ACL), activity modifications to reduce the risk of secondary injury before surgery, and the short- and long-term risks associated with delayed ACL reconstruction. This study aimed to determine whether longer wait times are associated with a prolonged decrease in quality of life and an increased incidence of secondary joint injury after ACL rupture.

Methods: We recruited 53 patients who presented between 2013 and 2017 at a single sports medicine minor injury clinic with a suspected acute ACL rupture, based on clinical examination; ACL rupture was confirmed on magnetic resonance imaging. Read More
