Results of arthroscopically assisted reduction and fixation of antero-medial coronoid facet fractures at short term follow-up.

J Shoulder Elbow Surg 2022 May 9. Epub 2022 May 9.

Osteoarticular Department, Orthopaedic and Traumatology Unit, Azienda Ospedaliera of Faenza, RA, Italy.

Background: Varus posteromedial rotatory instability is a typical pattern of elbow injury that involves fracture of the anteromedial facet (AMF) of the coronoid as well as injuries to the lateral ligament complex and the posterior bundle of the medial collateral ligament. Some Authors support the idea that subtype-2 AMF coronoid fractures require fixation to restore elbow stability, but this topic is still an issue in literature. The purpose of this study was to assess the clinical and radiological outcomes of arthroscopic-assisted reduction and fixation (ARIF) for AMF fractures. Read More

Intraoperative medial collateral ligament (MCL) injury during total knee arthroplasty (TKA) is a serious complication. External bracing and/or conversion to a constrained implant has previously been studied. The technique of using an internal high-strength suture brace to augment an MCL repair has been evaluated in the nonarthroplasty patient and could provide an alternate solution. Read More

Is Repair of a Small Coronoid Fracture Required in the Surgical Treatment of Terrible Triad Injury of the Elbow?

J Hand Surg Asian Pac Vol 2022 Apr 31;27(2):345-351. Epub 2022 Mar 31.

Department of Orthopaedic Surgery, Osaka City General Hospital, Japan.

Multiple treatment protocols have been described in literature for the treatment of terrible triad injury (TTI) of the elbow. We believe that repair of the medial collateral ligament (MCL) should be performed in preference to repair of a small coronoid fracture if the elbow is unstable after fixation/replacement of the radial head and repair of the lateral collateral ligament (LCL). The aim of this study is to report the outcomes of surgical treatment of patients with TTI associated with a small coronoid fracture in whom the coronoid fracture was not addressed. Read More

Current concepts on management of medial and posteromedial knee injuries.

J Clin Orthop Trauma 2022 Apr 18;27:101807. Epub 2022 Feb 18.

Sports Injury and Arthroscopy Division, Orthopaedics, Kasturba medical college, Manipal, Manipal academy of Higher education, Manipal, India.

Traditionally, while managing ligament injuries around the knee, medial side injuries are frequently overlooked or considered '' with very little influence on overall knee stability outcomes. However, much has changed in the recent past, and like the lateral side of the knee, it is gaining considerable attention. It is now well known that the Medial collateral ligament and Posteromedial corner are fundamentally two distinct structures that differ in anatomy and biomechanics. Read More

A Balanced Arthroscopic Debridement of the Inner Layer of the Knee Retinaculum Increases the Tibiofemoral Joint Space Width.

Adv Orthop 2022 29;2022:1766401. Epub 2022 Jan 29.

Centro de Innovación, Clínica MEDS, Santiago, Chile.

Introduction: Traditional techniques can enlarge the medial tibiofemoral joint space width (JSW) for meniscal repairs, but a remnant ligament laxity may be developed. Alternatively, the debridement of the inner retinaculum layer may result in a balanced JSW without causing extra-ligament damage (retinaculum layers II and collateral ligament).

Purpose: The purpose of this study was to determine whether a concentric arthroscopic debridement of the inner retinaculum layer increases the tibiofemoral JSW in patients with meniscal injuries. Read More

Editorial Commentary: The Anterior Cruciate Ligament May Be Safer Wearing a Suture Tape Augmentation Seat Belt: Click It or Ticket.

Arthroscopy 2021 11;37(11):3344-3346

Rush University Medical Center.

Bone-patellar tendon-bone autograft for anterior cruciate ligament (ACL) reconstruction has the most data to support its use. However, there may still be room for improvement, and younger age, insufficient rehabilitation, altered neuromuscular patterns, and precocious return to play can increase risk of graft failure. High strength suture augmentation of soft-tissue repair or reconstruction has gained traction in a variety of applications for the knee, including medial collateral and posteromedial corner, lateral collateral ligament, posterior cruciate ligament, and ACL.

Elbow Instability.

Semin Musculoskelet Radiol 2021 Aug 27;25(4):574-579. Epub 2021 Oct 27.

Department of Radiology, Balgrist University Hospital, Zurich, Switzerland.

The stability of the elbow is based on a combination of primary (static) and secondary stabilizers (dynamic). In varus stress, the bony structures and the lateral ulnar collateral ligament (LUCL) are the primary stabilizers, and in valgus stress, the ulnar collateral ligament (UCL) is the primary stabilizer. The flexor and extensor tendons crossing the elbow joint act as secondary stabilizers. Read More

Magnetic resonance imaging (MRI) and Computed topography (CT) analysis of Schatzker type IV tibial plateau fracture revealed possible mechanisms of injury beyond varus deforming force.

Injury 2022 Feb 1;53(2):683-690. Epub 2021 Oct 1.

Department of Trauma, Jiangsu Province Hospital, Jiangsu, China; First Affiliating Hospital of Nanjing Medical University, China. Electronic address:

Background: Schatzker type IV tibial plateau fractures (type IV TPFs) are known for complex fracture morphology and high frequency of knee subluxation. Varus deforming force has been believed to be the cause but which fails to explain the lateral tibial plateau comminution and the lateral femoral condyle bone edema observed on injury MRI. The purpose of this study is to further explore the mechanisms of injury of type IV TPFs by synthetically analysing the information obtained from MRI and CT of a cohort of patients. Read More

Fixation of Displaced Medial Epicondylar Fractures in Adolescents.

JBJS Essent Surg Tech 2021 Jul-Sep;11(3). Epub 2021 Jul 14.

Shriners Hospitals for Children-Philadelphia, Philadelphia, Pennsylvania.

Fractures of the medial epicondyle are often a marker of injury of the medial collateral ligament complex of the elbow, regardless of displacement. The medial epicondyle serves as the origin for the flexor/pronator mass superficially and the medial collateral ligament near the base. These fractures occur most commonly through the apophysis at the base of the epicondyle, making differentiation of muscular versus ligamentous avulsion difficult. Read More
