Review of Surgical Management Techniques for Osteochondral Lesions.

Early attempts at surgical management of cartilage lesions date back to the 1950s. Since then, various reconstructive techniques have been developed; unfortunately, none of the methods used has been able to produce a regenerate formed solely of hyaline cartilage. This paper summarizes the most popular techniques for chondral and osteochondral reconstructions of knee joint tissues.

Articular Cartilage Reconstruction with Hyaluronate-Based Scaffold Significantly Decreases Pain and Improves Patient's Functioning.

Articular cartilage lesions negatively affect patients' well-being, causing severe pain and significantly limiting functioning. The purpose of this study was to evaluate the effectiveness of a one-stage reconstruction, performed arthroscopically using a hyaluronate-based scaffold. Pain reduction and functional improvement were assessed.

Articular Cartilage Lesions Pathomechanism, Diagnosis, Epidemiology, Possibilities for Conservative Treatment.

Osteoarthritis, which is the most common joint disorder, is one of major reasons for hospitalizations and one of the greatest burdens to health care systems. Osteoarthritis has a complex etiology, but lesions of articular cartilage are a major risk factor. These lesions are often encountered in young active people and usually remain asymptomatic for a long time.

The Muscle Strength of the Knee Joint after ACL Reconstruction Depends on the Number and Frequency of Supervised Physiotherapy Visits.

The aim of this study in anterior cruciate ligament reconstruction (ACLR) patients was to assess the effect of six months of supervised physiotherapy with a higher number of visits (SPHNV) compared to supervised physiotherapy with a lower number of visits (SPLNV) on the maximal peak torque (PT) and isometric torque (IT) of values obtained for hamstring (H) and quadriceps (Q) muscles of the knee joints under isokinetic and isometric conditions. Hypothesis: SPHNV improves IT and PT more than SPLNV. Group I had ACLR with a higher number of visits ( = 20), Group II had ACLR with a lower number of visits ( = 20), and Group III served as the control ( = 20).

Platelet Receptor Activity for Predicting Survival in Patients with Intracranial Bleeding.

Blood coagulation disorders in patients with intracranial bleeding as a result of head injuries or ruptured aneurysms are a diagnostic and therapeutic problem and appropriate assessments are needed to limit CNS damage and to implement preventive measures. The aim of the study was to monitor changes in platelet aggregation and to assess the importance of platelet dysfunction for predicting survival. Platelet receptor function analysis was performed using the agonists arachidonic acid (ASPI), adenosine diphosphate (ADP), collagen (COL), thrombin receptor activating protein (TRAP), ristocetin (RISTO) upon admission to the ICU and on days 2, 3, and 5.

Micromorphological assessment of bone tissue remodeling in various hip degeneration conditions.

Background: The reorganization of bone tissue is closely associated with its metabolism and changes in its internal structure. Metabolism of the bone, which results from the simultaneous processes of resorption and formation of new bone tissue, may depend on the presence and type of arthritis.

Objectives: The objective of the study was to assess, based on the morphological features and mineral composition of bone tissue, changes in the femoral head in various types of hip joint degeneration.

Clinical evaluation of ankle arthrodesis with Ilizarov fixation and internal fixation.

Background: Ankle arthrodesis may have internal or external stabilization. We assessed whether the type of stabilization after ankle arthrodesis will affect: (1) functional outcome in Foot and Ankle Ability Measure (FAAM) scale, (2) pain level, (3) period of hospitalization, (4) rate of complications.

Methods: We retrospectively studied 47 individuals after ankle arthrodesis with Ilizarov fixation (group 1, n = 21) and internal stabilization (group 2, n = 26) at our institution in years 2007-2015.

Pedobarographic analysis of body weight distribution on the lower limbs and balance after ankle arthrodesis with Ilizarov fixation and internal fixation.

Background: A number of various techniques were proposed to stabilized ankle arthrodesis, among them external and internal fixation. Appropriate balance and adequate distribution of lower limb loads determine normal biomechanics of the locomotor system. We hypothesized that various techniques used to stabilize ankle arthrodesis may exert different effects on (1) balance and (2) distribution of lower limb loads.

Assessment of the distribution of load on the lower limbs and balance before and after ankle arthrodesis with the Ilizarov method.

Ankle arthrodesis with the Ilizarov method is an accepted form of treatment of advanced degenerative changes of the ankle joint. Incorrect balance and load distribution on the lower limbs may result in pain and dysfunction. The aim of the study was to assess the change of balance and load distribution in lower extremities in patients before and after ankle arthrodesis with the Ilizarov method.

Three-dimensional printing as a technology supporting the treatment of lower limb deformity and shortening with the Ilizarov method.

Background: Treatment of multiplanar deformities, especially in younger children, requires construction of a complex Ilizarov fixator, frequently with small dimensions. The aim of this study is to verify clinical application of a3D-printed bone model in treatment with the Ilizarov method.

Methods: The study involved a 6-year-old child in whom clinical and radiological examination revealed multiplanar deformity of the right leg.

Balance and lower limb loads distribution after Ilizarov corticotomy.

Introduction: Normal balance and symmetric distribution of lower limb loads are associated with adequate muscle strength, joint mobility and proprioception. The aim of this study was to analyze the distribution of lower limb loads and balance prior to and after axis correction and lengthening with Ilizarov method.

Materials And Methods: The prospective analysis included 20 patients from our clinic, who have been subjected to distraction-corrective lower limb corticotomies with the Ilizarov method in 2014-2015.

Increased Radiation but No Benefits in Pedicle Screw Accuracy With Navigation versus a Freehand Technique in Scoliosis Surgery.

Background: The clinical value of pedicle screws in spinal deformity surgery is well known; however, screw insertion is demanding and sometimes associated with complications. Navigation systems based on intraoperatively obtained three-dimensional (3-D) images were developed to minimize pedicle screw misplacements. However, there is a lack of data confirming superiority of navigation above other techniques.

The impact of direct vertebral rotation (DVR) on radiographic outcome in surgical correction of idiopathic scoliosis.

Introduction: Recent developments of spinal instruments allow to address nearly all components of idiopathic scoliosis. Direct vertebral rotation (DVR) maneuver was introduced to correct apical axial vertebral rotation. It is however still not well established how efficiently DVR affects results of scoliosis correction.

Radiological evaluation of ankle arthrodesis with Ilizarov fixation compared to internal fixation.

Introduction: We asked whether the type of ankle joint arthrodesis stabilization will affect: (1) rate of union, (2) rate of adjacted-joint arthritis, (3) malalignment of the ankle joint.

Material And Methods: We retrospectively radiological studied 62 patients who underwent ankle arthrodesis with Ilizarov external fixator stabilization (group 1,n=29) or internal stabilization (group 2,n=33) from 2006 to 2015. Radiologic outcomes were mesure by: (1) rate of union, (2) rate of adjacent-joint arthritis, (3) malalignment of the ankle joint.

Effect of elliptical deformation of the acetabulum on the stress distribution in the components of hip resurfacing surgery.

Hip resurfacing surgery is a matter of controversy. Some authors present very good late results of 99% survival outcomes. However, national records of implants point to the series of complications connected with biomechanical flaws of the implant.

Pedobarographic analysis of body weight distribution on the lower limbs and balance after Ilizarov corticotomies.

Background: Symmetrical distribution of the load of the lower limbs and balance are among the determinants of proper biomechanics of the musculoskeletal system. So far, it has not been elucidated whether the correction of the axis and the equalization of the length of the lower limbs allow for achieving proper balance and load distribution. The aim of the present study was to compare load distribution and balance of patients who underwent Ilizarov method corticotomies with healthy controls.

Influence of whiplash injury on cervical spine stability.

The aim of this study was to define the influence of whiplash injury on cervical spine stability.

To verify the results the authors examined the control group whose representatives have never suffered from any cervical spine injury and met all the exclusion criteria.

Evaluation of dynamic formation of cervical spine column based on functional radiological studies in patients after cervical spine injury.

The purpose of this study was to evaluate cervical spine function, based on our own functional method of roentgenometric analysis in patients who suffered from cervical spine sprain injury. Study involved 72 patients who suffered from cervical spine whiplash injury. Conventional plain radiographs in all patients included three lateral views: maximum flexion, neutral (resting) and maximum extension.

Comparison analysis of the operative treatment results of the femoral neck fractures using side-plate and compression screw and cannulated AO screws.

Introduction: Femoral neck fractures are among the most frequent and the most dangerous types of musculoskeletal injuries in the elderly population. There is general agreement that because of the morphology of the fracture, internal fixation is the treatment of choice irrespective of the degree of displacement. The optimal surgical treatment of femoral neck fractures remains controversial despite constant progress in the surgical management of such fractures and still remains a serious therapeutic problem.
