PURPOSE: To validate the medialization and anteriorization distances, and the osteotomy angle of anteromedialization tibial tubercle osteotomies using postoperative axial imaging. METHODS: From March 2004 to August 2015, 117 consecutive patients who underwent anteromedialization osteotomies of the tibial tubercle by a single surgeon were identified. Only patients with pre- and postoperative magnetic resonance imaging (MRI) studies were included. Using MRI multiplanar reformats, distances that the tibial tubercle was translated medially (medialization) and anteriorly (anteriorization) were measured...

BACKGROUND: Idiopathic genu valgum is a frequently diagnosed growth disorder in adolescence. Whenever the possibilities of conservative therapy have been exhausted, leg straightening by means of hemiepiphysiodesis has become the standard form of treatment. Because of their flexible screw-plate connection, eight-Plates have been reported in the literature to lead to lower complications regarding implant loosening and fracture compared to other implants. The aim of this retrospective survey was to analyse our own patient population who were treated for genu valgum by means of temporary hemiepiphysiodesis near the knee using eight-Plates to modulate growth...

Femoral varus osteotomy is a conservative treatment for external single-compartment gonarthrosis. This surgical procedure is little used and outcomes are little studied.This study aimed to assess the clinical and radiological results of femoral varising osteotomy in subjects with external femorotibial gonarthrosis associated with idiopathic genu valgum whose data were recorded over a period of 21 years (1992- 2013) in the Department of Orthopedics at Sahloul University Hospital, Sousse. The clinical evaluation of patients was performed using the IKS score (International Knee Society)...

BACKGROUND: Treating symptomatic osteochondral defects is challenging, especially in young adults with deep (>8-10 mm) empty defects after osteochondritis dissecans (OCD) or collapsed condyles secondary to avascular necrosis (AVN). For this population, osteoarthritis (OA) is inevitable if articular congruence is not restored. PURPOSE: To describe the autologous chondrocyte implantation (ACI) "sandwich" technique with autologous bone grafting (ABG) and compare it with ABG alone for restoration of the osteochondral unit...

PURPOSE: The purpose of this study was to examine the relationship between medial tibial joint line elevation and the improvement of range of motion (ROM) in unicompartmental knee arthroplasty (UKA). The hypothesis was that limited elevation of tibial joint line will improve knee range of motion in UKA. METHODS: Forty-six consecutive medial UKAs were enrolled in this study. Medial tibial joint line elevation was defined as the polyethylene insert and tibial tray thickness minus the tibial osteotomy and sawblade thickness...

The discoid meniscus is a rare anomaly of the knee that affects mostly the lateral meniscus and is often asymptomatic. The osteochondritis dissecans is a disorder of the subchondral bone and articular cartilage and occurs frequently associated with the discoid lateral meniscus. In the present case, we showed the evolution of this association related to surgical treatment. A patient with lateral knee pain and a magnetic resonance depicting a torn discoid lateral meniscus and osteochondritis dissecans of the lateral femoral condyle was treated with partial meniscectomy and meniscal sutures...

EDITORIAL
Andrew J Cosgarea
Excessive lateralization of the tibial tuberosity is one of the anatomic factors that contribute to lateral patellar instability, which we usually correct surgically with tibial tuberosity osteotomy. Traditionally, coronal alignment was determined clinically by measuring the Q angle, which has proven to be unreliable. Radiographic measurements of coronal alignment made using computed tomography and magnetic resonance imaging are more reliable and have become the standard for determining the need for corrective tibial tuberosity osteotomy...

BACKGROUND: A certain percentage of patients undergoing anterior cruciate ligament (ACL) reconstruction will experience graft failure, and there is mounting evidence that an increased posterior tibial slope (PTS) may be a predisposing factor. Theoretically, under tibiofemoral compression force (TFC), a reduced PTS would induce less anterior tibial translation (ATT) and lower ACL force. HYPOTHESIS: Ten-degree anterior closing wedge osteotomy of the proximal tibia will significantly reduce ACL force and alter knee kinematics during robotic testing...

INTRODUCTION: Patellofemoral dysbalance may be caused by trochlear dysplasia, an elevated TTTG distance, femoral or tibial torsional deformities, patella alta, or a genu valgum. The surgical procedure for the treatment of a genu valgum is varisation osteotomy, usually in the femoral aspect. Several authors believe that a genu valgum is one cause of patellofemoral dysbalance, but studies about the outcome of the treatment with a varisation osteotomy are rare. MATERIALS AND METHODS: Nineteen knees in 18 patients, aged on average 28 (16-52) years were investigated in a retrospective study...

INTRODUCTION: Traumatic uncontained bone defect in the knee joint is one of the most serious knee injuries. As the knee joint is the main weight-bearing joint of the body, the problem of weight loading should be addressed while restoring the bone defect. However, no consensus exists regarding the treatment of this injury. PRESENTATION OF CASE: Two patients in separate cases initially sustained traumatic uncontained proximal tibial bone defects secondary to passenger traffic accidents...

OBJECTIVES: To test the hypothesis that autologous iliac bone grafts do not enhance clinical results and do not decrease complication rates in patients undergoing medial opening-wedge high tibial osteotomy. METHODS: Forty patients allocated in a randomized, two-armed, double-blinded clinical trial were evaluated between 2007 and 2010. One group received bone graft, and the other group was left without filling the osteotomy defect. The primary outcome was the Knee Society Score...

A 68-year-old man with right knee varus osteoarthritis was treated by lateral closed-wedge high tibial osteotomy. A correction loss with non-union occurred 6 months after surgery and a re-correction osteotomy was performed. Removing the proximal screws of the lateral plate, a medial opening-wedge re-osteotomy was performed. Arthroscopically harvested osteophytes were used to fill the gap after opening. An additional medial locking plate was installed on the medial side. Finally, the proximal lateral screws were reinserted and locked again...

BACKGROUND: Spontaneous osteonecrosis of the knee (SONK) is a clinical entity identified by acute knee pain usually associated with joint effusion, with radiographic findings of a radiolucent defect on the weightbearing area of the femoral condyle. Conservative treatment is initially undertaken; however, surgical procedures are often necessary. Historically, surgical options have included core decompression, cartilage repair, high tibial osteotomy, or joint arthroplasty. Few studies in the literature have reported the use of fresh osteochondral allograft (OCA) for the treatment of SONK lesions...

BACKGROUND: Patient-specific instrumentation (PSI) is attracting attention as a mechanical method of ensuring the accuracy of osteotomy during total knee arthroplasty (TKA). Few studies have focused on preoperative plans; thus, it is unclear how often initial plans have to be corrected preoperatively and intraoperatively. We investigated the frequency of corrections, the accuracy of intraoperative osteotomy, and postoperative alignment. METHODS: We analyzed 45 knees of 40 patients who underwent TKA using magnetic resonance imaging (MRI)-based PSI...

Purpose: High Outerbridge grade lesions of the articular cartilage have been associated with poor outcomes of high tibial osteotomy (HTO). However, there has been no report on the efficacy of HTO in the presence of kissing lesions. The purpose of this study was to compare clinical and radiographic outcomes of HTO between kissing lesion and non-kissing lesion groups. Materials and Methods: Of the patients with medial compartment osteoarthritis and varus deformity treated with HTO between 2007 and 2012, 21 cases with kissing lesions and 22 cases without kissing lesions were selected...
