Midterm Outcome of Subtalar Joint Revision Arthrodesis

Background: The outcomes of revision subtalar arthrodesis have received relatively little focus in research compared with primary subtalar arthrodesis outcomes. This study aimed to assess the midterm clinical and radiologic results of subtalar joint revision arthrodesis and to analyze the risk factors that might influence the outcome of this procedure. Methods: We performed a retrospective review of 20 patients after subtalar joint revision arthrodesis for malunion, using interposition of iliac crest bone graft. The mean age was 55.75 years and the average follow-up lasted for 48.93 months. Eighty-five percent of the patients had at least 1 risk factor identified prior to revision. Patients’ satisfaction and functional outcomes were evaluated with the American Orthopaedic Foot & Ankle Society Scale (AOFAS), the Foot and Ankle Outcome Score (FAOS), the Foot Function Index (FFI), and dynamic pedobarography. Results: A fusion rate of 80% was recorded whereas 20% of the cases ended with a painful pseudarthrosis requiring additional surgery. Pedobarographic measurements demonstrated that loading has a propensity toward the lateral column, but no substantial effect on the gait of patients. In this group, the following patient-reported outcomes were observed: 70% of the patients were satisfied, 20% of the patients found the result fair, and 10% were not satisfied with the results. Compared with the preoperative evaluation, postoperative functional scores showed significant improvement on the FOAS, AOFAS, and FFI outcome scales. Conclusions: Revision arthrodesis of the subtalar joint remains a challenging issue with a relatively high rate of nonunion, especially in a population of patients with multiple risk factors. Level of Evidence: Level IV, retrospective case series.

Intra-Articular Injections in Knee Osteoarthritis: A Review of Literature

Knee osteoarthritis (OA) is a chronic, degenerative, and progressive disease of articular cartilage, producing discomfort and physical disability in older adults. Thirteen percent of elderly people complain of knee OA. Management options for knee OA could be divided into the following categories: conservative, pharmacological, procedural, and surgical. Joint replacement is the gold standard, reserved for severe grades of knee OA, due to its complications rate and increased risk of joint revision. A nonsurgical approach is the first choice in the adult population with cartilage damage and knee OA. Yearly, more than 10% of knee OA-affected patients undergo intra-articular injections of different drugs, especially within three months after OA diagnosis. Several molecules, such as corticosteroids injection, hyaluronic acid (HA), and platelet-rich plasma (PRP), are managed to reduce the symptoms of patients with knee OA. The aim of this review was to offer an overview of intra-articular injections used for the treatment of OA and report the conventional pharmacological products used.

Treatment of an extensive acetabular defect in a patient with aseptic instability of a total hip arthroplasty

The aim of the study is to demonstrate, using a clinical example, the possibility of treating a patient with a severe acetabular defect by performing a one-stage revision arthroplasty using an individual design. Materials and methods. A 45-year-old female patient was admitted with complaints of pain, limitation of movement in the right hip joint, and gait disturbance. From anamnesis at the age of 5 years, reconstructive operations of the hip joints were performed. In 1991, CITO performed primary total arthroplasty of the right hip joint with an endoprosthesis from ESKA Implants. In 1998, due to the instability of the acetabular component of the total endoprosthesis of the right hip joint, revision arthroplasty was performed, and the cup was placed with a cement fixation. In 2001, for left-sided dysplastic coxarthrosis, primary total arthroplasty of the left hip joint was performed. In 2012, due to the instability of the total endoprosthesis of the left hip joint, revision arthroplasty was performed using an ESI anti-protrusion ring (ENDOSERVICE) with a cement cup and a Zweimller-type femoral component; the femur defect was repaired using a fresh frozen cortical graft. In October 2019, instability of the total endoprosthesis of the right hip joint was revealed, for which revision endoprosthetics was performed using an individual acetabular component. Results. The HHS index before revision arthroplasty was 21 points, after 1 month after surgery 44 points, after 3 months after surgery 65, after 6 months 82. Quality of life was assessed according to the WOMAC scale: before surgery 73 points, after 1 month after surgery 54 points, after 3 months 31, after 6 months 15 points. At the time of the last consultation, the patient moves with a cane, lameness persists, associated with scar reconstruction and atrophy of the gluteal muscles. Conclusion. The use of individual structures allows to restore the support ability of the lower limb and the function of the hip joint in the case of an extensive defect of the pelvic bones of the pelvic discontinuity type.

SURGICAL TREATMENT OF THE KNEE JOINT CONTRACTURES AFTER TOTAL KNEE ARTHOPLASTY

Background: The development of contractures after total knee replacement is most often associated with arthrofibrosis and makes up 1.3% - 5.7% of the total number of cases of joint replacement. Conservative treatment is ineffective. Arthrolysis is pathogenetically substantiated (arthroscopic or open). Aims: assessment of the effectiveness of arthrolysis as a method of treating knee joint contractures after arthroplasty, comparison of the results of arthroscopic and open arthrolysis, analysis of complications. Materials and methods: Compare two groups. In group 1, 57 patients underwent arthroscopic arthrolysis. In group 2, 54 patients underwent open arthrolysis. The operations were performed from 2015 to 2019, the observation period ranged from one year to three years. As criteria for the result of treatment, KSS data were used (general and functional assessment of the knee joint), as well as separately the amplitude of movements in the joint before surgery and at different times after it. Results: One of the results of this work was the optimization of arthroscopic arthrolysis technique. Improved surgical access and joint revision sequence. According to the KSS scale and range of motion, the best results were obtained in group 1. Especially important is the lesser number of complications in comparison with the 2nd group requiring repeated interventions, including revision arthroplasty. In the 1st group of such cases there were 3 (5.3%), in the 2nd group - 7 (13.0%). Conclusions: Arthroscopic arthrolysis is a less traumatic and more effective treatment for arthritis of the knee. It seems appropriate to gradually displace open arthrolysis by arthroscopic.

The role of external osteosynthesis in treatment of unstable pelvic osseous injuries

Objective. To specify the role and indications for application of аpparatus of external fixation (АEF) in treatment of unstable pelvic osseous injuries (UPOI); to study up the advantages and faults of the external fixation method; to share the experience of treatment, using this procedure. Маterials and methods. There were 229 patients, suffering pelvic injuries, examined on the base of orthopedic-traumatological centre of Kyiv’s Regional Clinical Hospital in 2005 - 2017 yrs and distributed into three Groups. In Group I 143 (62.4%) injured persons were included, in whom external osteosynthesis played the function of temporary measures of fixation, in Group II - 27 (11.8%) patients, in whom while hospitalization a fracture was fixed, using AEF, аnd after stabilization of the state the posterior pelvis osteosynthesis and reposition was conducted, in Group III - 59 (25.8%) patients, who, using several indications, were definitely treated, applying the external fixation method only. Results. Excellent effect of treatment in Group I was registered in 23 (19.0%), a good one - in 58 (47.9%), satisfactory - in 32 (26.4%), poor - in 8 (6.6%) of 121 patients; in Group II - accordingly, - in 5 (20.8%), 11 (45.8%), 7 (29.2%) and 1 (4.2%) of 24 patients; in Group III - accordingly, in 4 (8.3%), 12 (25%), 23 (47.9%) and 9 (18.6%) of 48 patients. Conclusion. Best results of treatment of patients with unstable pelvic osseous injuries were obtained while applying the tactics of change from external fixation into internal one. On the first stage the pelvic ring fixation, using AEF, was performed, аnd after stabilization of a patient general status - internal osteosynthesis. Application of the internal osteosynthesis method permits to control and stabilize the reposition achieved, to conduct the sacro-ileal joint revision.

Results and Patient Reported Outcome Measures (PROMs) after One-Stage Revision for Periprosthetic Joint Infection of the Hip: A Single-centre Retrospective Study

Background: Little is known about functional outcome and quality of life (QoL) after one-stage revision for periprosthetic joint infection (PJI) of the hip.Methods: a cohort of 30 subjects treated with one-stage revision between 2011 and 2015 was identified, and questionnaires on functional outcome and QoL were distributed.Results: 28 subjects were successfully treated (93%). Most subjects were referred from other hospitals. Coagulase-negative Staphylococcus was found in 50% of the cases, and 40% of all cultured bacteria were multidrug-resistant. 25% had subsequent revision surgery, unrelated to PJI. Functional outcome was good and QoL scores were high, comparable to prosthetic joint revision surgery in general.Conclusion: Although the cohort was small and statistical analysis was not performed, this study showed that excellent results can be obtained with one-stage revision for hip PJI. Functional outcome and QoL was comparable to prosthetic joint revision surgery in general.
