Endoscopic Treatment of Deep Gluteal Syndrome: 3-Portal Technique.

We describe all-endoscopic deep gluteal syndrome treatment and sciatic nerve decompression at the infrapiriformis space. Surgery is performed with the patient in the prone position with the usual arthroscopic instruments and pump. The first step includes performing placement of 2 initial portals (medial and median) without fluoroscopy in the area of the ischial tuberosity and conjoint tendon, as well as release in this area with a subsequent shift in the lateral direction.

Extra-Articular Endoscopic BP Decompression-Surgical Technique.

We describe all-endoscopic brachial plexus (BP) decompression. Surgery is performed with the patient in the beach-chair position with the usual arthroscopic instruments and pump. The first step is to create 2 portals at the area of the coracoid process and decompress the infraclavicular part of the BP at area of thoracic aperture and coracoid.

Long-Term Structural Changes in the Osteochondral Unit in Patients with Osteoarthritis Undergoing Corrective Osteotomy with Platelet-Rich Plasma or Stromal Vascular Fraction Post-Treatment.

This pilot study examined the long-term structural changes in the osteochondral unit of 20 patients with knee osteoarthritis (KOA) who underwent high tibial osteotomy (HTO) and received post-treatment with either platelet-rich plasma (PRP) or stromal vascular fraction (SVF). Ten patients were injected with autologous PRP (PRP subgroup), while another ten patients received autologous SVF (SVF subgroup) six weeks after surgery and were monitored for 18 months. Histological samples of bone and cartilage (2 mm in diameter and 2 cm long) were taken from tibial and femoral sites during surgery and 18-month post-HTO, and morphometric analyses were conducted using Mega-Morf12 software.

Material And Methods: Ankle distraction hinged motion arthroplasty in the Ilizarov frame was performed in 10 patients with terminal post-traumatic osteoarthritis (mean age 54±6.2 years).

Gait analysis and knee kinematics before, and 6 and 18 months after corrective valgus osteotomy.

Background: The study objective was to assess clinical outcomes and gait biomechanics in patients after 6 and 18 months after varus deformity (VD) surgical correction at knee joint (KJ).

Method: The study included 20 patients with medial osteoarthritis (OA) of the knee of grade 2-3 and a VD of >4°. A total of 21 surgeries were performed on the patients.

ANKLE DISTRACTION ARTHROPLASTY: A SYSTEMATIC REVIEW.

Epidemiological data suggest 9-15% of ankle joint osteoarthritis (AOA) in the general population. One of the methods of delaying radical intervention is ankle joint distraction arthroplasty of the ankle joint (ADA), including a combination of various techniques. The lack of publications summarizing the maximum possible clinical data on ADA for more than 50 years of the method's history justifies the need for a review.

Differences in Synovial Cytokine Profile Associated with Long-Term Clinical Outcomes in Patients with Knee Osteoarthritis Undergoing Corrective Osteotomy with Platelet-Rich Plasma or Stromal Vascular Fraction Post-Treatments.

Functional outcomes and synovial fluid (SF) cytokine concentrations in response to platelet-rich plasma (PRP) or stromal vascular fraction (SVF) post-treatments following open wedge high tibial osteotomy (HTO) in 20 patients with knee osteoarthritis (OA) were examined. Six weeks after surgery, the knees of 10 patients were injected with autologous PRP (PRP subgroup), while another 10 patients were injected with autologous SVF (SVF subgroup) and monitored for 1.5 years.

[EXPERIENCE IN ARTHROSCOPIC TREATMENT OF PATIENTS WITH HAGLUND'S DEFORMATION].

This study aimed to evaluate the results of treatment of patients with anterolateral chronic instability after arthroscopic stabilization of the ankle joint using anchor fixators, to determine the risk factors for the recurrence of instability after surgery and methods of their diagnosis. The study involved 28 patients from 2016 to 2020. performed 28 arthroscopic operations for chronic lateral instability.

Gait analysis and knee joint kinematics before a and 6 month after of corrective valgus osteotomy at patients with medial knee arthritis.

Purpose: A varus deformity (VD) of the lower limbs results in greater loading of the medial compartment of the knee joint (KJ), leading to its degenerative changes and, eventually, to progressive osteoarthritis (OA) of the joint. The aim of the study was to investigate the mid-term changes in gait biomechanics and clinical symptoms in patients with VD of KJ and OA before and six months after surgical correction.

Methods: The study enrolled 25 patients with medial OA of grade 2-3 according to Kellgren-Lawrence and a VD of > 3°, who underwent arthroscopic lavage and debridement of the knee joint followed by corrective osteotomy.

[Clinical and functional outcomes of valgus osteotomy in patients with medial gonarthrosis (preliminary results)].

Objective: To analyze gait biomechanics before and after corrective osteotomies around the knee joint in patients with medial gonarthrosis.

Material And Methods: The study recruited 5 patients (6 surgeries) with medial gonartrosis and varus knee deformity. Gait biomechanics was analyzed in preoperative period and 6 months later.

[Endoscopic sciatic nerve decompression].

Objective: To improve treatment outcomes in patients with sciatic nerve neuropathy.

Material And Methods: The first results of endoscopic sciatic nerve decompression in 6 patients with sciatic neuropathy (mean age 47±6.7 years) are presented.

[CLINICAL CASE OF ENDOSCOPIC BRACHIAL PLEXUS DECOMPRESSION IN A PATIENT WITH ROTATOR CUFF RUPTURE AND POST TRAUMATIC PLEXOPATHY].

Posttraumatic brachial plexopathy - is an actual problem, which is usually seen after shoulder area trauma and is often accompanied with intraarticular pathology. In case of failed conservative treatment, open brachial plexus decompression is an effective procedure, however, it is pretty traumatic and is accompanied by number of complications and recurrences, what explains the necessity of development of low-traumatic, miniinvasive alternative techniques. Purpose - develop a new mini-invasive endoscopic technique of brachial plexus decompression.

[EXPERIENCE OF USING INSPACE SUBACROMIAL BALLOON FOR TREATMENT OF PATIENTS WITH LARGE AND MASSIVE ROTATOR CUFF TEARS].

The large and massive rotator cuff tears lead to a significant decrease in the shoulder joint (SJ) function and the development of severe pain syndrome in it. Frequently, such injuries are difficult to recover fully, and the number of relapses after their recovery is quite high. The combined method of rotator cuff repair single-row suture anchor technique with concomitant use of a subacromial balloon spacer, allows to achieve the best results in the treatment of this group of patients.

Biomechanical Changes in Gait Patterns of Patients with Grade II Medial Gonarthritis.

Deforming osteoarthritis (OA) of the knee is a progressive disease associated with pain and compromised function of the joint. Typical biomechanical modifications in the gait of subjects with medial knee OA are characterized by decreased gait speed and overload on the affected limb. The borderline stage for conservative versus surgical management is Grade II OA.

[EXPERIENCE IN ARTHROSCOPIC TREATMENT OF PATIENTS WITH HAGLUND'S DEFORMATION].

The goal of this study was to evaluate the results of arthroscopic calcaneoplasty for the treatment of posterior calcaneal bursitis and Haglund's disease. The study involved 28 patients who underwent 30 arthroscopic surgeries for Haglund's disease from 2015 to 2019. Retrocalcanealneoplasty and supracalcaneoplasty were performed using a shaver, an ablator; with the help of a drill, the bone was resected until the contact in the Achilles tendon was eliminated in the position of dorsiflexion of the foot.

[A COMPARISON OF RESULTS BETWEEN HOOK PLATE AND TIGHTROPE FOR ACUTE ACROMIOCLAVICULAR JOINT DISLOCATION].

Purpose the study - despite of this fact that there are different surgical techniques to treat acromioclavicular dislocation and also the surgery remains controversial, the purpose of our study is to compare the results of surgery treatment to acromioclavicular joint dislocation on the condition of surgical method: Hook Plate versus TightRope. Between 2015 and 2019, 30 patients were with acute Rockwood type III-VI acromioclavicular dislocation at the age of 23-54. Patients were divided into 2 groups according to the surgical methods (Hook plate: n=15; TightRope: n=15)to compare the functional outcome after using either Hook plate and TightRope stabilization.
