BACKGROUND: Access to health care services is a critical component of health care reform and may differ among patients with different types of insurance. Hypothesis/Purpose: The purpose was to compare adolescents with private and public insurance undergoing surgery for anterior cruciate ligament (ACL) and/or meniscal tears. We hypothesized that patients with public insurance would have a delayed presentation from the time of injury and therefore would have a higher incidence of chondral injuries and irreparable meniscal tears and lower preoperative International Knee Documentation Committee (IKDC) scores than patients with private insurance...

This report presents the first case of a knee dislocation following septic arthritis after arthroscopy. A 65-year-old woman had an arthroscopy with irrigation and debridement (I&D) of the joint and microfracture for the chondral lesions. She had complaints of postarthroscopic infection but non-steroidal anti-inflammatory medication and local ice compression was recommended. She revisited her physician twice and at the last visit she had a large purulent effusion in her knee. The gram stain of the joint fluid aspirate demonstrated gram-positive cocci and the cultures grew methicilline-sensitive Staphylococcus aureus...

BACKGROUND: Anterior tibial spine fractures (ATSF) in the skeletally immature parallel anterior cruciate ligament (ACL) tears in adult patients, yet these injuries are generally regarded as mutually exclusive. Biomechanical analysis suggests that intrinsic ACL damage occurs during ATSF, and long-term clinical studies demonstrate residual anteroposterior knee laxity following ATSF. We aim to describe prevalence, demographics, and characteristics of pediatric patients who sustained ATSF with concomitant ACL injury...

Growth factors such as transforming growth factor beta1 (TGF-β1), have critical roles in the regulation of the chondrogenic differentiation of mesenchymal stem cells (MSCs), which promote cartilage repair. However, the clinical applications of the traditional growth factors are limited by their high cost, functional heterogeneity and unpredictable effects, such as cyst formation. It may be advantageous for cartilage regeneration to identify a low-cost substitute with greater chondral specificity and easy accessibility...

Articular cartilage injuries experienced at an early age can lead to the development of osteoarthritis later in life. In situ 3D printing is an exciting and innovative bio-fabrication technology that enables the surgeon to deliver tissue- engineering techniques at the time and location of need. We have created a hand- held 3D printing device (Biopen) that allows the simultaneous co-axial extrusion of bioscaffold and cultured cells directly into the cartilage defect in vivo in a single session surgery. This pilot study assesses the ability of the Biopen to repair a full thickness chondral defect and the early outcomes in cartilage regeneration, and compares these results to other treatments in a large animal model...

We reviewed a series of 50 consecutive wrist arthroscopy patients who had been investigated pre-operatively by direct magnetic resonance arthrography and calculated the sensitivity, specificity, positive predictive value, negative predictive value and overall accuracy of magnetic resonance arthrography in detecting full-thickness triangular fibrocartilage complex tears, intrinsic carpal ligamentous lesions, wrist synovitis and chondral lesions in the radiocarpal joint. The sensitivities of magnetic resonance arthrography in detecting central triangular fibrocartilage complex tears, peripheral triangular fibrocartilage complex tears, scapholunate ligament tears, lunotriquetral ligament tears, dorsal synovitis and radiocarpal chondral lesions were 89%, 63%, 71%, 100%, 32% and 65%, respectively, and its specificities in detecting these lesions were 91%, 98%, 89%, 94% 94% and 97%, respectively...

PURPOSE: Patellofemoral osteoarthritis (PFOA) occurs in approximately half of anterior cruciate ligament (ACL)-injured knees within 10-15 years of trauma. Risk factors for post-traumatic PFOA are poorly understood. Patellofemoral alignment and trochlear morphology may be associated with PFOA following ACL reconstruction (ACLR), and understanding these relationships, particularly early in the post-surgical time period, may guide effective early intervention strategies. In this study, patellofemoral alignment and trochlear morphology were investigated in relation to radiographic features of early PFOA 1-year post-ACLR...

Scaffolds laden with stem cells are a promising approach for articular cartilage repair. Investigations have shown that implantation of artificial matrices, growth factors or chondrocytes can stimulate cartilage formation; but no existing strategy apply mechanical stimulation on stratified scaffolds to mimic the cartilage environment. The purpose of this study was to adapt a spraying method for stratified cartilage engineering and to stimulate the bio-substitute. Human Mesenchymal Stem Cells from Bone Marrow (BM-MSCs) were seeded in an Alginate/Hyaluronic Acid (Alg/HA) or Alg/Hydroxyapatite (Alg/Hap) gel to direct cartilage and hypertrophic cartilage/sub-chondral bone differentiation, respectively, in different layers linked with polyelectrolyte multilayer films, in a single scaffold...

BACKGROUND: Previous studies have reported varying return-to-sport protocols after knee cartilage restoration procedures. PURPOSE: To (1) evaluate the time for return to sport in athletes with an isolated chondral injury who underwent an accelerated return-to-sport protocol after osteochondral autograft plug transfer (OAT) and (2) evaluate clinical outcomes to assess for any consequences from the accelerated return to sport. STUDY DESIGN: Case series; Level of evidence, 4...

BACKGROUND: There are limited data regarding associated factors of return to sports activities at more than 5 years after anterior cruciate ligament (ACL) reconstruction. PURPOSE: To test interrelationships between patient characteristics, concomitant articular lesions, graft laxity, and maintenance of sports activities at 5 to 10 years after ACL reconstruction. It was hypothesized that at 5 to 10 years after the operation in young adult men, maintenance of greater activity level and better knee function would be associated with greater preinjury activity level, younger age at reconstruction, absence of concomitant articular lesions, and minimal graft laxity at follow-up...

BACKGROUND: Isolated chondral fractures of the knee are a rare and challenging problem, typically occurring with an acute traumatic event such as dislocation of the patella or ligamentous injury. Historically, repair of unstable chondral fragments without osseous attachment has not been recommended due to concerns about the limited healing potential of cartilage. PURPOSE: To describe a technique for fixation of large isolated chondral fractures of the knee and present 3 cases where large chondral fragments without osseous attachment were fixed successfully with chondral darts and biologic adhesive...

BACKGROUND: Although arthroscopic surgical treatment of the first metatarsophalangeal (MTP) joint involves painful sesamoid excision, synovectomy, debridement, and partial cheilectomy, no gold standard treatment technique has been defined in the literature for hallux rigidus and focal osteochondral lesions. This study aimed to assess the arthroscopic treatment for early grade focal osteochondral lesions of the first MTP joint and to determine the impact of arthroscopic microhole drill surgery on foot function and activities of daily living in a group of patients who failed conservative treatment...

The Bosworth fracture is a pattern of fracture-dislocation of the ankle joint with fixed dislocation of the proximal part of the fibula behind the posterior malleolus. It is a rare injury, which requires high index of suspicion for diagnosis. Fixed dislocation of the fibula does not allow for closed reduction, so open reduction and fixation of fibula or tibia is required. We present a case report of a patient who suffered a Bosworth fracture, with associated medial malleolus fracture. She underwent surgical treatment with open reduction and internal fixation of the fibula and tibia...
