Operative Repair of Hamstring Injuries From the Jackling Position in Rugby.

Background: The jackling position within rugby has not been previously described as a mechanism for proximal hamstring injuries.

Hypothesis: Acute surgical repair of proximal hamstring avulsion injuries sustained from the jackling contact position enables a return to a previous level of sporting activity with low risk of recurrence.

Study Design: Case series; Level of evidence, 4.

Surgical excision of bilateral patella stress fractures in an elite marathon runner.

Vertical stress fractures of the patella are rare, with only a handful of bilateral cases reported. Stress fractures in the athletic community are often due to repetitive strain and submaximal loading, with minimal recovery time. An Olympic marathon runner in her 30s presented with right anterolateral knee pain.

Surgical Repair of Stener-like Injuries of the Medial Collateral Ligament of the Knee in Professional Athletes.

Background: A "Stener-like" lesion of the knee is defined as a distal avulsion of the superficial medial collateral ligament (sMCL) with interposition of the pes anserinus between the ligament and its tibial insertion-a displacement impeding anatomic healing. Because of the scarcity of these injuries, the literature is limited to case reports and small case series.

Purpose: To assess the effect of surgical repair of acute Stener-like lesions of the sMCL on the following outcomes: return to preinjury level of sporting function; time to return to preinjury level of sporting function; functional performance; injury recurrence; and any other complications.

Centrosomal enrichment and proteasomal degradation of SYS-1/β-catenin requires the microtubule motor dynein.

The Wnt/β-catenin asymmetry (WβA) pathway utilizes asymmetric regulation of SYS-1/β-catenin and POP-1/TCF coactivators. WβA differentially regulates gene expression during cell fate decisions, specifically by asymmetric localization of determinants in mother cells to produce daughters biased toward their appropriate cell fate. Despite the induction of asymmetry, β-catenin localizes symmetrically to mitotic centrosomes in both mammals and .

Efficacy of Surgical Tenodesis for Treatment of Distal Semitendinosus Hamstring Tendon Injuries.

Background: Understanding the optimal management of distal semitendinosus hamstring injuries is critical for reducing pain, restoring preinjury function, maintaining knee stability, improving hamstring muscle strength, and minimizing the risk of complications and recurrence. To our knowledge, the outcomes of surgical tenodesis for distal semitendinosus hamstring injuries have not been previously reported.

Hypothesis: Surgical tenodesis for injuries of the semitendinosus would enable return to preinjury level of sport with low risk of recurrence.

Incidence of Symptomatic Venous Thromboembolism in Proximal Hamstring Repair: A Prospective Cohort Study.

Background: Surgical repair of proximal hamstring avulsion injuries can enable the return to preinjury levels of sporting function and minimize the risk of recurrence in both professional and recreational athletes. While venous thromboembolism (VTE) is a recognized complication of surgical repair, the incidence thereof is poorly reported in the literature.

Purpose/hypothesis: To report the incidence of symptomatic VTE after proximal hamstring avulsion repair and assess the efficacy of our thromboprophylaxis protocol.

North central London elective orthopaedic network and health service innovation to improve the quality of NHS patient care.

Health service innovation is required to meet the ever-growing demands of modern medicine. This editorial discusses the transformation of the north central London elective orthopaedic network and the essential principles which future integrated care systems could incorporate.

The future of orthopaedic surgical education: Where do we go now?

Introduction: COVID-19 will undoubtedly change the future landscape of medical and surgical education. The economic and environmental advantages of virtual learning are clear, while access to a wider range of resources and subject specialists makes the adoption of virtual learning within surgical education an attractive prospect.

Aims: This literature review aims to evaluate evidence on the effectiveness of virtual education in orthopaedics and how we might implement positive changes to educational practice in the future, as a result of lessons learned during the COVID-19 pandemic.

Fracture of heterotopic mass in the lower limb: surgical case report and review of the literature.

Heterotopic ossification (HO) is a rare sequela of sports injuries with a predominance in young active males located within bulky muscle planes. In most cases it is self-limiting and spontaneous resolution can occur. Fractures of HO are sparsely reported within the literature.

Analysis of the Exeter V40 femoral stem prosthesis fracture : systematic review and single centre case series.

Aims: The Exeter V40 cemented polished tapered stem system has demonstrated excellent long-term outcomes. This paper presents a systematic review of the existing literature and reports on a large case series comparing implant fractures between the Exeter V40 series; 125 mm and conventional length stem systems.

Methods: A systematic literature search was performed adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria.

Chronic tophaceous gout mimicking widespread metastasis.

Gout is a common crystal-induced arthropathy affecting mainly the joints of the appendicular skeleton; however, rarely this condition affects the axial skeleton as well. Spinal gout can cause radiculopathy, cord compression, canal stenosis and discitis. We describe a case of a 71-year-old woman where the initial presentation of destructive arthropathy and spinal masses secondary to axial gout was mistaken for a metastatic malignancy.

Surgical Repair of Distal Biceps Femoris Avulsion Injuries in Professional Athletes.

Background: Understanding the optimal management of distal biceps femoris avulsion injuries is critical for restoring preinjury function, restoring hamstring muscle strength, increasing range of motion, and minimizing risk of complications and recurrence. Due to the rarity of these injuries, prognosis and outcomes within the literature are limited to case reports and small case series.

Purpose: To assess the effect of surgical repair for acute distal avulsion injuries of the biceps femoris tendon on (1) return to preinjury level of sporting function and (2) time to return to preinjury level of sporting function, patient satisfaction, and complications.

The introduction of day-case total knee arthroplasty in a national healthcare system: A review of the literature and development of a hospital pathway.

Introduction: As we now drive to reinitiate our full capacity elective services in an attempt to tackle an ever-growing demand for lower limb arthroplasty, this pandemic has presented rare opportunities to revise and re-engage elective arthroplasty pathways aimed at improving patient care and healthcare efficiency.

Aims: We present the development of an evidence-based multidisciplinary perioperative care pathway for day-case total knee arthroplasty (TKA) in a United Kingdom National Health Service (NHS) institution, in conjunction with a review of the literature upon which the protocol is founded.

Methodology: We performed a review of the literature reporting complication or readmission rates at ≥30 day postoperative following day-case TKA.

Day-case total hip arthroplasty: a literature review and development of a hospital pathway.

Aims: We present the development of a day-case total hip arthroplasty (THA) pathway in a UK National Health Service institution in conjunction with an extensive evidence-based summary of the interventions used to achieve successful day-case THA to which the protocol is founded upon.

Methods: We performed a prospective audit of day-case THA in our institution as we reinitiate our full capacity elective services. In parallel, we performed a review of the literature reporting complication or readmission rates at ≥ 30-day postoperative following day-case THA.
