PURPOSE: This study was designed to analyze the relationship between changes in posterior tibial slope and the absence or presence of lateral hinge fracture, diagnosed in the sagittal and axial planes, as well as the coronal plane, by computed tomography (CT) following opening wedge high tibial osteotomy (HTO). METHODS: This study involved 55 patients (55 knees) undergoing opening wedge HTO for primary medial osteoarthritis. Lateral hinge fractures were evaluated on CT scans according to the Takeuchi classification and were also classified as subtypes A, B, and C, depending on anterior, posterior, and both anterior and posterior cortical disruptions, respectively, as determined by the sagittal and axial planes of CT scans which corresponded to the fracture line visible on coronal CT scans...

Introduction: High tibial osteotomy (HTO) is a frequent and effective treatment for unicompartmental gonarthritis. Only a few articles are focused on the treatment of infected nonunion. Patient and Method: A 50-year-old obese patient was operated on by medial opening-wedge HTO. She developed a painful nonunion treated by hardware removal, allograft, and plate fixation. However, the nonunion persisted. 2 years later, cellulitis appeared with an abscess adjacent to the HTO plate...

BACKGROUND: Cranial cruciate ligament rupture is a prevalent injury in dogs, and tibial plateau leveling osteotomy (TPLO) is one of the preferred surgical techniques. Surgical site infection is a possible complication following TPLO and measurement of serum acute phase proteins is suggested to be a way to early recognize and distinguish postoperative infectious complications from normal postoperative inflammatory conditions. In this study we investigate the changes in concentrations of the systemic inflammatory markers C-reactive protein (CRP) and serum amyloid A (SAA) following tibial plateau leveling osteotomy (TPLO) in dogs and evaluate if deviations from the changes expectedly induced by the surgical procedure are useful in early detection of post-surgical infections...

BACKGROUND: We aimed to determine the change in hindfoot alignment after high (HTO) or low tibial osteotomy (LTO), which is commonly performed to prevent the progression of arthritis of the knee or ankle. METHODS: We retrospectively reviewed the radiographic findings of patients who underwent HTO or LTO for arthritis with varus deformity of the knee or ankle joint. The hindfoot alignment view angle (HAVA), hindfoot alignment ratio (HAR), and hindfoot moment arm (HMA) were measured using the hindfoot alignment radiographs...

PURPOSE: This study aimed to analyse the change in coronal tibiofemoral (CTF) subluxation after high tibial osteotomy and to determine demographic variables associated with CTF subluxation. The change in CTF subluxation was hypothesised to be associated with the magnitude of correction of lower limb alignment and medial proximal tibial angle (MPTA). METHODS: A total of 103 consecutive knees in 86 patients who underwent medial opening wedge high tibial osteotomy for symptomatic medial compartment knee osteoarthritis were retrospectively analysed...

BACKGROUND: Young patients with severe medial osteoarthritis, varus malalignment and insufficiency of the anterior cruciate ligament (ACL) are difficult to treat. The tibial slope has gained attention with regard to osteotomies and ligamentous instability. The purpose was to evaluate the outcome of combined high tibial osteotomy (HTO), ACL reconstruction and chondral resurfacing (CR, abrasion plus microfracture), and to analyse graft failure rates with regard to the tibial slope. METHODS: Fifty cases (48...

PURPOSE OF REVIEW: The purposes of this review are to (1) describe the anatomic and biomechanical rationale for high tibial osteotomy (HTO) in the setting of posterior cruciate ligament (PCL) deficiency, (2) review the indications for concomitant HTO and PCL reconstruction, (3) provide guidance for the clinical assessment of the patient with suspected PCL deficiency, and (4) summarize the key surgical steps necessary to attain the appropriate sagittal and coronal plane corrections. RECENT FINDINGS: The preponderance of available biomechanical data pertaining to the PCL-deficient knee suggests that an increased proximal tibial slope limits posterior tibial translation under axial compressive loads...

Purpose: The purpose of this study was to investigate whether surgical experience could improve surgical competency in medial open wedge high tibial osteotomy (MOWHTO). Materials and Methods: One hundred consecutive cases of MOWHTO were performed with preoperative planning using the Miniaci method. Surgical errors were defined as under- or overcorrection, excessive posterior slope change, or the presence of a lateral hinge fracture. Each of these treatment failures was separately evaluated using the cumulative summation test for learning curve (LC-CUSUM)...

Low-profile fixation devices for medial opening wedge high tibial osteotomy (OWHTO) were developed in order to avoid skin irritation and additional invasion. However, the low-profile system is associated with additional risks. We report three cases of locking pin back out with the low-profile locking plate system for medial OWHTO.

PURPOSE: For opening-wedge high tibial osteotomy, previous studies have shown that most osteotomies were anterior-inclined. The purpose of this study was to determine the effect of sagittal osteotomy inclination on the anteroposterior translation of osteomized fragments and discuss its possible impact on the patellofemoral joint. METHODS: We retrospectively measured the angle between the joint line and the sagittal osteotomy line. We also evaluated the anteroposterior translation of osteomized fragments by measuring the distance from the most posterior point of the tibial plateau to the tibial tuberosity and the anterior cortical line...

PURPOSE: To assess whether the increased inclination of the tibial plateau on the coronal view after opening-wedge high tibial osteotomy affects radiographic coronal alignment, clinical outcomes, and cartilage findings. METHODS: After adjustment for the preoperative medial proximal tibial angle (MPTA), patients who underwent opening-wedge high tibial osteotomy were retrospectively divided into those with postoperative MPTA values of 95° or less (normal group) and greater than 95° (increased group), with each group containing 43 knees...

Osteoarthritis is a globally common disease that imposes a considerable ongoing health and economic burden on the socioeconomic system. As more and more biomechanical factors have been explored, malalignment of the lower limb has been found to influence the load distribution across the articular surface of the knee joint substantially. In this work, a three-dimensional finite element analysis was carried out to investigate the effect of varying the high tibial osteotomy correction angle on the stress distribution in both compartments of the human knee joint...

Aim: It has been suggested that the use of a pilot-hole may reduce the risk of fracture to the lateral cortex. Therefore the purpose of this study was to determine the effect of a pilot hole on the strains and occurrence of fractures at the lateral cortex during the opening of a high tibial osteotomy (HTO) and post-surgery loading. Materials and Methods: A total of 14 cadaveric tibias were randomized to either a pilot hole (n = 7) or a no-hole (n = 7) condition...

Sanjay Kumar, S V Sonanis
Introduction: Coronal deformities are commonly encountered in paediatric orthopaedics and surgical treatment is indicated for severe deformities causing pain, function and cosmetic problems. In a growing bone, major surgical intervention like osteotomy with internal or external fixation can be avoided by growth modulation (hemiepiphysiodesis) using 8-plates. Our aim is to review the published literature on the use of 8-plates for deformity correction. Methods: We conducted a systematic review on 8-plate growth modulation for coronal deformity correction...

A biplanar osteotomy aiming to anteromedialize the anterior tibial tuberosity to realign the patellofemoral joint described by Prof. Fulkerson is one of the classical operations to address many pathologies of the patellofemoral joint. The procedure is evidence-based and effective for the management of patellofemoral pain and osteoarthritis, confirming that the original ideas and concepts are still valid, and still stand strong. In high-demand patients, the Fulkerson osteotomy offers good opportunities of success in terms of return to sport...

Medial open wedge high tibial osteotomy (MOWHTO) is a commonly performed procedure for symptomatic medial compartment osteoarthritis (OA). However, little is known about its effects on ipsilateral ankle or hindfoot. The aim of our study was to determine the incidence of ankle or hindfoot problems after MOWHTO and examine its association with radiological indices. Thirty-five knees (32 patients) undergoing navigated MOWHTO were evaluated for the presence of new-onset ankle or hindfoot symptoms after surgery...

The aim of this meta-analysis was to compare the effects of closing-wedge (CW) and opening-wedge (OW) high tibial osteotomies (HTOs) on the change in leg length. Our hypotheses were that leg length will increase after OW HTO and decrease after CW HTO, and the magnitude of the change in leg length would be negligible in both techniques. Multiple databases including MEDLINE, Embase, and Cochrane were searched for studies comparing the change in leg length after HTO with that before HTO. After testing for publication bias and heterogeneity, we aggregated variables by using the random-effects model...
