Avascular necrosis of the capitellum after surgical treatment of a coronal shear fracture of the distal humerus: A case report.

Introduction And Importance: Coronal shear fractures of the distal humerus are rare and are expected to have a high incidence of avascular necrosis (AVN) due to the avascular nature of the capitellar bone fragment and limited soft tissue attachment. However, according to the literature published thus far, AVN is infrequently reported, and some studies suggest that it does not have a significant impact on clinical outcomes.

Case Presentation: Two female patients, one aged 72 and the other 70, presented with coronal shear fractures of distal humerus.

Effect of Medial Closing Wedge Distal Femoral Varization Osteotomy on Coronal Ankle and Hindfoot Alignment.

Background: To date, only a few studies have reported postoperative changes in coronal ankle alignment after valgus knee correction through medial closing wedge distal femoral varization osteotomy (MCWDFO). This study aimed to measure the changes of MCWDFO on coronal ankle and hindfoot alignment.

Methods: We retrospectively reviewed the radiographic findings of 27 consecutive patients (34 cases) with knee valgus malalignment who underwent MCWDFO for either lateral knee joint osteoarthritis (OA) or recurrent patellar subluxation/dislocation (RPD).

Diagnosis and treatment for primary Candida parapsilosis infection of the native knee joint: A case report.

Introduction And Importance: Candida arthritis is a very rare disease and Candida parapsilosis infection of the native knee joint is extremely rare. It is challenging to diagnose and treat because the clinical manifestations, laboratory and radiologic findings are not specific and not well defined. We report the rare case of C.

A rare intramuscular osteolipoma: A case report.

Introduction: Lipomas are frequently presented in adults and account for almost 50% of all soft-tissue tumors. Osteolipomas are rare and usually located in the intraosseous region or adjacent to bone. It is very unusual for osteolipomas with no connection to bony structures.

The long-term structural effect of orthoses for pediatric flexible flat foot: A systematic review.

Background: We aimed to evaluate the structural effects of the long-term use of orthoses for pediatric flexible flat foot (PFFF) using an algorithmic approach and a structured critical framework to assess the methodological quality of reported studies.

Methods: A comprehensive literature search using five databases, namely MEDLINE, the Cochrane Library, Scopus, the Web of Science, and EMBASE, was performed for pertinent articles published before March 30, 2018. Studies with quantitative data on the effects of the long-term use of orthoses for PFFF were included.

Is Bone Grafting Necessary in Opening Wedge High Tibial Osteotomy? A Meta-Analysis of Radiological Outcomes.

Purpose: Bone grafting in opening wedge high tibial osteotomy (OWHTO) is still controversial. The purpose of this study is to compare the radiological outcomes of OWHTO with bone graft (autogenous, allogenous, and synthetic bone graft) and those without bone graft.

Materials And Methods: PubMed, MEDLINE, EMBASE and Cochrane Register of Studies databases were searched using specific inclusion and exclusion criteria for radiological studies involving OWHTO with bone graft and without bone graft groups.

Locking plate versus non-locking plate in open-wedge high tibial osteotomy: a meta-analysis.

Purpose: The purpose of this study was to conduct a meta-analysis to determine whether the locking plate or non-locking plate results in better opening-wedge high tibial osteotomy (OWHTO) outcomes.

Methods: The MEDLINE, EMBASE, COCHRANE, and KOREAMED register databases were searched for studies. The eligibility criteria for inclusion in the review were studies that compared the locking plate with the non-locking plate for OWHTO, and those that provided clear descriptions of surgical techniques and outcomes.

Medial Soft-Tissue Realignment Versus Medial Patellofemoral Ligament Reconstruction for Recurrent Patellar Dislocation: Systematic Review.

Purpose: To compare the clinical outcomes between medial soft-tissue surgery and medial patellofemoral ligament (MPFL) reconstruction for recurrent patellar dislocation without any evident predisposing factors.

Methods: A literature search was performed on the established medical databases MEDLINE, EMBASE, and the Cochrane register. The inclusion criteria were as follows: English-language papers for recurrent patellar dislocation without any evident predisposing factors, clinical trial(s) with clear description of surgical technique, adult subjects, medial soft-tissue surgery or MPFL reconstruction without combined surgery, and a follow-up longer than 2 years.

Total knee arthroplasty after failed high tibial osteotomy: a systematic review of open versus closed wedge osteotomy.

Purpose: Medial opening wedge high tibial osteotomy (HTO) has become increasingly popular as an alternative to lateral closing wedge osteotomy for the treatment of medial compartment knee osteoarthritis with varus deformity. The present systematic review was conducted to provide an objective analysis of total knee arthroplasty (TKA) outcomes following previous knee osteotomy (medial opening wedge vs. lateral closing wedge).

Safe Zone for Medial Open-Wedge Supramalleolar Osteotomy of the Ankle: A Cadaveric Study.

Background: The purpose of this present study was to determine the incidence of lateral cortical fracture depending on the plane of osteotomy in medial open-wedge supramalleolar osteotomy (SMO) and to define a safe zone through which a medial open-wedge SMO could be performed with minimal risk of lateral cortical fracture.

Materials And Methods: Matched pairs of fresh-frozen human cadaver lower leg specimens were obtained from 7 males and 3 females (average age = 63.9 [range 49-75] years).

Anatomical Single-bundle Anterior Cruciate Ligament Reconstruction Using a Freehand Transtibial Technique.

Purpose: In anatomical single-bundle (SB) anterior cruciate ligament (ACL) reconstruction, the traditional transtibial approach can limit anatomical placement of the femoral tunnel.

Surgical Technique: We present a novel three-point freehand technique that allows for anatomic SB ACL reconstruction with the transtibial technique.

Materials And Methods: Between January 2012 and December 2012, 55 ACL reconstructions were performed using the three-point freehand technique.

Clinical Outcome of Posterior Cruciate Ligament Reconstruction With and Without Remnant Preservation.

Purpose: The purpose of this study was to analyze clinical outcomes in patients who underwent posterior cruciate ligament reconstruction (PCLR) with and without remnant preservation.

Methods: A search of the literature was performed with the established medical databases Medline, Embase, and the Cochrane Register. Two authors screened the selected articles for title, abstract, and full text in accordance with predefined inclusion and exclusion criteria.

Radiographic evaluation of complete and incomplete discoid lateral meniscus.

Objectives: The aim of this retrospective study was (1) to evaluate the radiographic features to differentiate arthroscopically confirmed complete and incomplete discoid lateral meniscus (DLM) (2) to determine the cutoff values for any parameter that was found to differentiate complete from incomplete DLM.

Materials And Methods: We retrospectively analyzed plain knee radiographs of 130 arthroscopically proven DLM. Seventy-nine patients had complete DLM and 51 patients incomplete DLM.

Spontaneous healing of a displaced bucket-handle tear of the lateral meniscus in a child.

Bucket-handle tears less frequently occur in the lateral meniscus than in the medial meniscus. An 11-year-old male patient complained of painful swelling and locking due to a displaced bucket-handle tear of the lateral meniscus. We recommended an arthroscopic surgery; however, the patient left the hospital without surgical treatment.

Localized pigmented villonodular synovitis of the proximal tibiofibular joint.

Pigmented villonodular synovitis (PVNS) is a rare disease. It is a benign neoplastic process typically affecting young to middle-aged adults and most commonly involving the knee, hip, and shoulder joints. The symptoms include diffuse pain and swelling with discomfort.

Tunnel volume enlargement after posterior cruciate ligament reconstruction: comparison of achilles allograft with mixed autograft/allograft--a prospective computed tomography study.

Purpose: The purpose of this study was to evaluate and compare femoral and tibial tunnel volume enlargement (TVE) after arthroscopic posterior cruciate ligament (PCL) reconstruction by remnant bundle preservation using Achilles allograft or mixed graft.

Methods: Seventy-eight patients undergoing primary arthroscopic single-bundle PCL reconstruction were initially included. Fifty-six of these patients underwent follow-up for a minimum of 1 year postoperatively and were divided into 2 groups: group A received Achilles allograft (n = 27), and group B received mixed graft (n = 29).
