Fabella Syndrome and Common Peroneal Neuropathy following Total Knee Arthroplasty.

Case: A 62-year-old man presented with persistent lateral knee pain 15 months following an uncomplicated total knee arthroplasty. There was a tendinous snapping structure over the lateral aspect of the knee in deep flexion with positive Tinel's sign over the fibular head. The patient underwent an uncomplicated flabella excision.

Nonoperative and Operative Soft-Tissue and Cartilage Regeneration and Orthopaedic Biologics of the Knee: An Orthoregeneration Network (ON) Foundation Review.

Orthoregeneration is defined as a solution for orthopedic conditions that harnesses the benefits of biology to improve healing, reduce pain, improve function, and optimally, provide an environment for tissue regeneration. Options include: drugs, surgical intervention, scaffolds, biologics as a product of cells, and physical and electro-magnetic stimuli. The goal of regenerative medicine is to enhance the healing of tissue after musculoskeletal injuries as both isolated treatment and adjunct to surgical management, using novel therapies to improve recovery and outcomes.

Purpose: The purpose of this study is to investigate the impacts of social media usage, age, and patient reported wait times on online ratings for three popular review websites.

Study Design: Cross-sectional study.

The 2020 NBA Orthobiologics Consensus Statement.

This 2020 NBA Orthobiologics Consensus Statement provides a concise summary of available literature and practical clinical guidelines for team physicians and players. We recognize that orthobiologic injections are a generally safe treatment modality with a significant potential to reduce pain and expedite early return to play in specific musculoskeletal injuries. The use of orthobiologics in sports medicine to safely reduce time loss and reinjury is of considerable interest, especially as it relates to the potential effect on a professional athlete.

Plasma D-dimer Does Not Anticipate the Fate of Reimplantation in Two-stage Exchange Arthroplasty for Periprosthetic Joint Infection: A Preliminary Investigation.

Background: Inflammatory markers such as the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels have always been a part of the diagnostic criteria for periprosthetic joint infection (PJI), but they perform poorly anticipating the outcome of reimplantation. D-dimer has been reported in a small series as a potential marker to measure infection control after single-stage revisions to treat PJI. Nonetheless, its use to confirm infection control and decide the proper timing of reimplantation remains uncertain.

Two reviewers examined all literature pertaining to sport outcomes following all-inside meniscal repair.

Impact of Body Mass Index on the Accuracy of Physical Examination and MRI of the Shoulder.

Background: The physical examination of overweight patients can require specific adaptations. Orthopaedic literature on the impact of body mass index (BMI) on the physical examination of the shoulder is virtually nonexistent.

Purpose: To assess whether BMI affects the sensitivity and specificity of common shoulder tests, using arthroscopy as a gold standard.

Time to closure of orthopaedic surgical incisions: a novel skin closure device versus conventional sutures.

Objective: New technologies are being developed to optimise healing of surgical incisions. BandGrip (US) is a micro-anchor skin closure device that replaces the need for subcuticular suturing and further dressing. The purpose of this study is to perform a matched cohort analysis comparing time to closure of surgical incisions between sutures and the novel skin closure device.

Methods: Forty-eight patients enrolled by 8 surgeons from 8 separate institutions were included in this study. Patients underwent microfracture augmented by cartilage allograft extracellular matrix (BioCartilage; Arthrex, Naples, FL) and were followed at designated time points (3, 6, 12, and 24 months) to assess patient-reported outcomes (PROs), clinically significant outcomes (CSOs), and failure and complication rates.

Osteochondral Allograft Transplant for Focal Cartilage Defects of the Femoral Condyles: Clinically Significant Outcomes, Failures, and Survival at a Minimum 5-Year Follow-up.

Background: Osteochondral allograft (OCA) transplant for symptomatic focal cartilage defects in the knee has demonstrated favorable short- to midterm outcomes. However, the reoperation rate is high, and literature on mid- to long-term outcomes is limited.

Purpose: To analyze clinically significant outcomes (CSOs), failures, and graft survival rates after OCA transplant of the femoral condyles at a minimum 5-year follow-up.

Bacterial contamination of protective lead garments in an operating room setting.

Background: Protective lead garments (PLG) worn in the operating room are a potential source for bacterial colonisation and thus may increase the risk of intraoperative infection. The clinical significance of such bacterial contamination has yet been established. Although disinfection protocols have been employed, their effectiveness is also unknown.

Hyaluronic acid and platelet-rich plasma for the management of knee osteoarthritis.

Purpose: Symptomatic knee osteoarthritis (OA) remains a substantial cause of pain and disability worldwide and effective management in young patients without indications for total knee arthroplasty remains challenging. Intra-articular injections represent a viable option in the non-operative treatment of knee OA. Hyaluronic acid (HA) and platelet-rich plasma (PRP) are two commonly utilized intra-articular treatment modalities that are of particular clinical interest in the current literature.

Pelvic ring reconstruction with segmental spinal instrumentation after complete type I pelvic resection.

Background And Objectives: Internal hemipelvectomy is a complex procedure used to treat malignancy that involves the pelvis. Reconstruction of the pelvis after type I or type I/IV resection remains controversial due to high complication rates and debatable functional benefit. Modern reconstruction options may provide a rapid, intuitive, and reliable way to reconstitute the pelvic ring.

Outcomes of the Latarjet Procedure Versus Free Bone Block Procedures for Anterior Shoulder Instability: A Systematic Review and Meta-analysis.

Background: Free bone block (FBB) procedures for anterior shoulder instability have been proposed as an alternative to or bail-out for the Latarjet procedure. However, studies comparing the outcomes of these treatment modalities are limited.

Recommendations to Optimize the Safety of Elective Surgical Care While Limiting the Spread of COVID-19: .

Unlabelled: COVID-19 has drastically altered our lives in an unprecedented manner, shuttering industries and leaving most of the country in isolation as we adapt to the evolving crisis. Orthopedic surgery has not been spared from these effects, with the postponement of elective procedures in an attempt to mitigate disease transmission and preserve hospital resources as the pandemic continues to expand. During these turbulent times, it is crucial to understand that although patients' and care-providers' safety is paramount, canceling or postponing essential surgical care is not without consequences and may be irreversibly detrimental to patients' health and quality of life in some cases.

Meniscal Allograft Transplantation: Indications, Techniques, Outcomes.

Meniscal allograft transplantation (MAT) has become an acceptable surgical treatment for select symptomatic and relatively young (<50 years of age) patients with a meniscal deficiency. MAT may also be considered in meniscal-deficient patients undergoing anterior cruciate ligament reconstruction and/or articular cartilage repair procedure in the ipsilateral compartment. Contraindications to MAT include asymptomatic patients, severe osteoarthritis, uncorrectable malalignment or instability, irreparable chondral damage, active infection, or inflammatory arthropathy.
