Evaluation of Functional Outcome Following Hybrid External Fixation in The Management of Schatzkers Type V and VI Tibial Plateau Fractures - A Prospective Study of 30 Patients.

Authors:
Y Subash

Malays Orthop J 2021 Mar;15(1):48-54

Department of Orthopaedics, Saveetha University Saveetha Medical College and Hospital, Chennai, India.

Introduction: Fractures of the proximal tibia are high velocity injuries often associated with soft tissue compromise especially in the type V and VI fracture patterns. Dual plating is the preferred treatment option for these injuries but not in a setting where there is extensive soft tissue injury, as this can lead to problems with wound healing. The aim of this study was to evaluate the functional outcome following hybrid external fixation in the management of Schatzkers type V and VI fractures. Read More

Inside-out Medial Meniscal Repair: Improved Surgical Exposure With a Sub-semimembranosus Approach.

Arthrosc Tech 2021 Feb 16;10(2):e507-e517. Epub 2021 Jan 16.

Department of Orthopaedic Surgery, Washington University School of Medicine, St Louis, Missouri, U.S.A.

Inside-out meniscal repair is considered the gold standard for reparable tears of the medial and lateral menisci despite the recent popularity of all-inside devices. Accurate suture passage is required to perform a stable repair as well as to prevent inadvertent neurovascular injury from the suture needles. Placement of a deep soft-tissue retractor is necessary to identify and retrieve these needles prior to tying the sutures. Read More

Authors:
Leslie J Bisson

Arthroscopy 2021 03;37(3):1053-1054

Many different autografts are available for anterior cruciate ligament reconstruction. Although patellar tendon graft and hamstrings are most commonly used, quadriceps tendon with or without a bone plug is gaining popularity. Preliminary evidence suggests that quad tendon without a bone plug performs at least as well as with a plug, although more comparative information is needed. Read More

Staged patellar tendon reconstruction using doubled bone-patellar tendon-bone allograft for infected patellar tendon rupture: a rare case report of three years follow-up.

J Exp Orthop 2021 Feb 18;8(1):13. Epub 2021 Feb 18.

Department of Orthopedic Surgery, Smarton Hospital, Bucheon, Korea.

Background: Patellar tendon rupture is a relatively rare injury that usually requires surgical treatment. The optimal therapeutic strategy is still controversial, especially when either concomitant patellar tendon infection or soft tissue infection surrounds the patellar tendon. Until recently, most reported reconstruction methods are extensive and difficult to apply because of the poor condition of the soft tissue surrounding the patellar tendon. Read More

Editorial Commentary: The Pivot Shift and Lachman Examinations: Teammates With Distinct Roles.

Arthroscopy 2021 02;37(2):682-685

New York, New York.

The pivot shift and Lachman examinations are "teammates" with complementary but distinct roles in the successful diagnosis and treatment of anterior cruciate ligament rupture and injury to the surrounding soft-tissue envelope of the knee. The Lachman test measures anterior tibial translation in response to an applied anterior tibial load. This test assesses the integrity of the native or reconstructed anterior cruciate ligament and the secondary medial restraints including the medial meniscus and medial collateral ligament. Read More

J Sports Sci 2021 Jan 28:1-7. Epub 2021 Jan 28.

School of Allied Health Sciences, Griffith University , Australia.

This study aimed to explore the association between hamstring strength, age and lower limb soft tissue injury history and subsequent hamstring injury among Australian Football League (AFL) players. This prospective cohort study recruited 125 players from three professional AFL teams. Eccentric knee flexor strength was assessed while performing the Nordic hamstring exercise in pre-season, and injury data were collected retrospectively (hamstring, groin, calf, quadriceps and knee), and prospectively (hamstring injuries) for one AFL playing season.

Sideswipe Injury of the Knee: The New Face of an Old Foe?

Niger Med J 2020 Sep-Oct;61(5):288-290. Epub 2020 Oct 13.

Department of Orthopaedics and Trauma, University College Hospital, Ibadan, Nigeria.

The term "sideswipe injury" has become synonymous and used interchangeably with the term "traffic elbow." However, with the continuous rise in the use of the tricycle as a means of public transportation in some developing countries, a rise in sideswipe injuries of various severities is being experienced. We report a case of sideswipe injury to the left knee region of a 45-year-old female who was a passenger in the backseat of a tricycle. Read More

Bone and non-contractile soft tissue changes following open kinetic chain resistance training and testosterone treatment in spinal cord injury: an exploratory study.

Osteoporos Int 2021 Jan 14. Epub 2021 Jan 14.

Spinal Cord Injury and Disorders, Hunter Holmes McGuire VAMC, Richmond, VA, 23249, USA.

Twenty men with spinal cord injury (SCI) were randomized into two 16-week intervention groups receiving testosterone treatment (TT) or TT combined with resistance training (TT + RT). TT + RT appears to hold the potential to reverse or slow down bone loss following SCI if provided over a longer period.

How to Address the Medial Patellofemoral Ligament, Tibial Tubercle, and Articular Cartilage in Patients With Recurrent Patellar Instability.

Instr Course Lect 2021 ;70:273-288

Patellofemoral instability is a common pathology especially in the adolescent female population. Prompt diagnosis and management is critical to prevent future episodes of instability as well as to reduce the risk of cartilaginous injury to the patellofemoral articular surface. Initial management of a first-time patellar dislocation has historically been nonsurgical; however, the presence of intra-articular loose bodies or osseocartilaginous injury may require surgical intervention.

Cell-based therapy in soft tissue sports injuries of the knee: a systematic review.

Expert Opin Biol Ther 2021 Jan 19:1-13. Epub 2021 Jan 19.

South West London Elective Orthopaedic Centre , Epsom, UK.

Introduction: An ever-increasing number of clinics are offering purportedly 'regenerative' stem-cell treatments, although cell-based therapies may not primarily act as stem cells and have shown the ability to regenerate end-target tissues in some clinical studies only. We aim to systematically review the evidence for their use in soft-tissue sports injuries of the knee.

Areas Covered: A search for articles pertaining to the use of preparations of, or containing, mesenchymal stem cells (MSCs) in human subjects in sports knee injuries yielded 14 relevant results for inclusion after screening: 7 used cultured MSCs, 5 bone marrow concentrate (BMC), and the remaining 2 evaluated stromal vascular fraction (SVF) and tenocyte-like-cells.

Patient-Reported Activity Levels Correlate With Early Cartilage Degeneration After Anterior Cruciate Ligament Reconstruction.

Am J Sports Med 2021 02 4;49(2):442-449. Epub 2021 Jan 4.

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

Background: The association between activity level after anterior cruciate ligament (ACL) reconstruction (ACLR) and development of posttraumatic osteoarthritis (PTOA) remains unclear. This study investigated the relationship of patient-reported outcomes and progressive cartilage degenerative changes at 3 years after ACLR.

Hypothesis: Higher activity levels, as measured by Marx scores, are significantly correlated with early cartilage degeneration after ACLR. Read More
