BACKGROUND: Modern management of human immunodeficiency virus (HIV) infection has afforded patients longevity while increasing the burden of arthroplasty procedures because of the increased risk of osteonecrosis, fragility fractures, and degenerative joint disease. Early publications on hip and knee arthroplasty in HIV-positive patients reported a high risk of complications, although some more recent publications demonstrated acceptable outcomes. Despite the widespread nature of the HIV pandemic, there is a paucity of literature addressing outcomes following joint arthroplasty in infected patients...

Objective This study tested the hypothesis that presolidified chitosan-blood implants are retained in subchondral bone channels perforated in critical-size sheep cartilage defects, and promote bone repair and hyaline-like cartilage resurfacing versus blood implant. Design Cartilage defects (10 × 10 mm) with 3 bone channels (1 drill, 2 Jamshidi biopsy, 2 mm diameter), and 6 small microfracture holes were created bilaterally in n = 11 sheep knee medial condyles. In one knee, 10 kDa chitosan-NaCl/blood implant (presolidified using recombinant factor VIIa or tissue factor), was inserted into each drill and Jamshidi hole...

PURPOSE: Joint-line restitution is one objective of unicompartmental knee arthroplasty (UKA). However, the joint line is often lowered when resurfacing femoral implants are used. The aim of this study was to compare the joint-line height in UKA performed by robotic-assisted and conventional techniques. METHODS: This retrospective case-control study compared two matched groups of patients receiving a resurfacing UKA between 2013 and 2016 by either a robotic-assisted (n = 40) or conventional (n = 40) technique...

INTRODUCTION: Osteonecrosis is an ischemic pathologic process associated with a number of conditions affecting a range of age groups. The problem faced in the management of osteonecrosis is whether conservative treatment is a viable and effective option for patients. In this systematic review, we investigated the efficacy of various nonoperative treatment modalities for hip and knee osteonecrosis, including pharmacological management and biophysical modalities. METHODS: We identified 16 studies based on electronic searches through the PubMed, Embase, CINAHL Plus, and Cochrane databases from January 2001 to November 2015...

BACKGROUND: Large osteochondral defects of the knee are a challenge for regenerative treatment. While matrix-guided autologous chondrocyte transplantation (MACT) represents a successful treatment for chondral defects, the treatment potential in combination with bone grafting by cancellous bone or bone block augmentation for large and deep osteochondral defects has not been evaluated. PURPOSE: To evaluate 1- to 3-year clinical outcomes and radiological results on magnetic resonance imaging (MRI) after the treatment of large osteochondral defects of the knee with bone augmentation and MACT...

Intranasal bevacizumab injections have been used in treating hereditary hemorrhagic telangiectasia (HHT)-related epistaxis since 2009. It is believed to be a safe and effective treatment for a selected group of HHT patients in reducing frequency and intensity of epistaxis, with few or none adverse effects. In this case report, however, we will describe a patient who developed bilateral osteonecrosis in the knees while undergoing regular intranasal submucosal bevacizumab injections. Although osteonecrosis previously has been documented in patients receiving bevacizumab intravenously in oncologic doses, thus far it has not been reported in patients treated with intranasal submucosal injections...

OBJECTIVE: Opening Wedge High Tibial Osteotomy (OWHTO) for knee osteoarthritis and for osteonecrosis has reported good results. Use of low intensity pulsed ultrasound (LIPUS) after OWHTO had become an option for the treatment of OWHTO since April 2016. The purpose of this study was to examine whether LIPUS has an accelerating effect on synostosis after OWHTO. MATERIALS AND METHODS: The control subjects were 24 patients with a total of 26 knees (9 male with knees and 15 female with 17 knees treated) treated with OWHTO only...

Osteonecrosis (ON) is usually considered treatment related in patients with acute lymphoblastic leukemia (ALL). We report two patients with presentation of ON at the time of ALL diagnosis. Both were females and diagnosed with ALL at age 8 and 14 years. In the latter, some symptoms and radiologically verified ON in both knees were still present after the end of ALL therapy. No pediatric patients have previously been reported with ON presenting before initiation of ALL therapy.

BACKGROUND: Osteonecrosis of the hips and knees is an often debilitating adverse event in children treated with glucocorticoids for leukemia and lymphoma but the impact of shoulder involvement has been understudied. Thus, we investigated the severity and functional impairment of shoulder osteonecrosis in a well-characterized population of pediatric patients treated for acute lymphoblastic leukemia or lymphoma. METHODS: We retrospectively reviewed orthopaedic clinic and physical therapy evaluations to determine range of motion (ROM), pain, and impact of magnetic resonance-defined osteonecrosis (ON) on activities of daily living...

OBJECTIVE: Bipolar radiofrequency (bRF) ablation is gaining popularity as a treatment modality for unstable knee chondral lesions of the knee. Limited reports of osteonecrosis and chondrolysis have been published; however, there is little data examining the safety of this treatment in larger series. This study aims to evaluate the safety and efficacy of bRF in the treatment of chondral lesions encountered during knee arthroscopy. DESIGN: A retrospective evaluation of adverse outcomes in patients that underwent treatment of chondral lesions using bRF was undertaken...

BACKGROUND: Joint salvage surgery for patients with juxtaarticular osteosarcoma remains challenging, especially when the tumor invades the epiphysis. Because patients are surviving longer with current chemotherapy regimens, it is advantageous to retain native joints if possible, especially in young patients. However, the results using joint-preserving tumor resections in this context have not been well characterized. QUESTIONS/PURPOSES: (1) What are the functional outcomes after limb salvage surgery at a minimum of 3 years? (2) What are the oncologic outcomes? (3) Is joint salvage surgery for epiphyseal tumors associated with an increased risk of local recurrence compared with metaphyseal tumors not invading the epiphysis? (4) What are the complications associated with joint salvage surgery? METHODS: Between 2004 and 2013, we treated 117 patients with juxtaarticular osteosarcoma; of those, 43 (38%) were treated with joint salvage surgery, and 41 (95%) of the 43 patients are included in our study...

Some surgeons have been hesitant to use cementless fixation for total knee arthroplasty (TKA) in elderly patients due to concerns regarding successful bone biological fixation. Therefore, this study evaluated: (1) implant survivorship, (2) functional outcomes, (3) radiographic outcomes, and (4) complications in patients over 75 years of age who underwent cementless total knee arthroplasty. A total of 134 patients (142 TKAs) older than 75 years at a single institution between June 2008 and June 2014 were retrospectively reviewed...

AIM: Medial meniscus tear has been proposed as a potential etiology of spontaneous osteonecrosis of the knee (SONK). Disruption of collagen fibers within the meniscus causes meniscal extrusion, which results in alteration in load distribution in the knee. Our purpose was to determine whether the extent of medial meniscus extrusion correlates with the severity of SONK in the medial femoral condyle. METHODS: Radiological stage of SONK and femorotibial angle (FTA) were determined on knee radiographs...
