ONE-YEAR RESULTS OF BRACING FOR PATELLO-FEMORAL OSTEOARTHRITIS. PROSPECTIVE RANDOMIZED STUDY.

Acta Ortop Bras 2021 May-Jun;29(3):127-131

Universidade de São Paulo, Faculty of Medicine, Hospital das Clínicas, Institute of Orthopedics and Traumatology, HC-FMUSP, São Paulo, SP, Brazil.

Objective: To compare the long-term effects of a brace designed to stabilize the patellofemoral (PF) joint in comparison to a standard neoprene sleeve for the knee with patellar hole in patients with patellofemoral osteoarthritis (PFOA).

Methods: 38 patients with PFOA and comorbidities received either a functional PF brace (Study Group, SG) or a neoprene sleeve for the knee (Control Group, CG). Both groups received clinical treatment to OA and comorbidities according to a program from the institution. Patients were evaluated with Western Ontario and MacMaster (WOMAC) and Lequesne questionnaires, 30-second chair stand test (30CST), Timed Up and Go (TUG), anthropometric measures and self-reported physical activity in minutes/week at inclusion, one, three and twelve months after placing the brace. X-Rays were taken to measure the angles.

Results: At one year there was more abandonment in the CG without differences in weight and body mass index between groups during the study. The SG maintained improvements in Lequesne and WOMAC total and subsets during the year, whereas the CG returned to baseline values for pain, function and total (p < 0.01). TUG and 30CST results were always better in the study group without any clinically important improvement in both groups.

Conclusion: Long-term use of functional brace added to self-management program improves pain and function in patients with PFOA

IMPROVEMENTS IN HIP OSTEOARTHRITIS WITH LAVAGE, TRIAMCINOLONE AND HYLAN G-F20.

Acta Ortop Bras 2020 Nov-Dec;28(6):280-286

Universidade de São Paulo, Hospital das Clínicas, Medical School, Institute of Orthopedics and Traumatology, São Paulo, SP, Brazil.

Objective: To verify whether the use of Hylan G-F20 improves saline lavage and triamcinolone injection results in the treatment of hip osteoarthritis (HOA).

Methods: 82 patients with HOA categorized as grades II and III severity, according to Kellgren and Lawrence criteria, were randomized into the groups: lavage and triamcinolone (G0); lavage, triamcinolone, and 2 mL of hylan G-F20 (G1); lavage, triamcinolone, and 4mL of hylan G-F20 (G2); lavage, triamcinolone, and 6mL of hylan G-F20 (G3). The VAS, range of motion (ROM), WOMAC, and Lequesne questionnaires were administered at baseline, one, three, six, and twelve months post-injection.

Results: All groups showed clinically relevant improvements (> 20%) between baseline and first month post-injection, maintaining subjective results throughout the study period (p < 0.001). We found no differences between groups in any subjective evaluations (p > 0.05, for all). G2 and G3 obtained improved flexion results up to a year (p = 0.028). Hylan groups presented an improved external rotation since the first postoperative month and maintained the results up to a year (G1, p = 0.041; G2, p = 0.007), whereas G0 showed no improvement (p = 0.336).

Conclusion: Hip lavage and triamcinolone injection, with or without the use of hylan, improves pain, function, and quality of life up to a year in HOA. Hylan may improve ROM up to one year.

PROFILE OF PATIENTS WITH OSTEOPOROTIC FRACTURES AND FACTORS THAT DECREASE PREVENTION.

Acta Ortop Bras 2019 Mar-Apr;27(2):95-99

Universidade de São Paulo, Faculdade de Medicina, Hospital das Clínicas, Department of Orthopedics and Traumatology, São Paulo, SP, Brazil.

Objective: To evaluate the epidemiological profile of patients with osteoporotic fractures compared to patients with osteoarthritis (OA) and identify factors that diminish adherence to secondary prevention.

Methods: A total of 108 patients with osteoporotic fractures (OF) were compared to 86 patients with OA.

Results: Patients in the OF group were older (p < 0.001); had a lower body mass index (p < 0.001); were less literate (p = 0.012); were more frequently Caucasian (p = 0.003); were less frequently married (p < 0.001); experienced more falls, cognitive deficiency, previous fractures, old fracture, falls in the last year, and fall fractures; needed more help and took more medicine for osteoporosis (p < 0.05); and showed less pathology in the feet, muscle weakness, less vitamin D intake, and lower Katz & Lawton scores (p < 0.001). Factors that increased the chance of nonadherence included older age (p = 0.020), falls (p = 0.035), cognitive deficiency (p = 0.044), and presence of depression/apathy/confusion (p < 0.001).

Conclusion: Patient age, ethnicity, marital status, previous falls, foot pathologies, muscle weakness, previous fractures, use of vitamin D, use of osteoporosis drugs, and lower Katz & Lawton scale score defined the OF group. Factors that increased the chance of nonadherence included older age, sedative use, cognitive disorders, and symptoms of depression/apathy/confusion.

RANDOMIZED PROSPECTIVE STUDY ON THE TREATMENT OF FEMORO-PATELLAR OSTEOARTHRITIS USING BRACING.

Acta Ortop Bras 2019 Mar-Apr;27(2):85-91

Universidade de São Paulo, Faculdade de Medicina, Hospital das Clínicas, Department of Orthopedics and Traumatology, São Paulo, Brazil.

Objective: To compare the effect of a brace designed to stabilize the patellofemoral joint to that of a patella-shaped neoprene sleeve with patella cut out in patients with patellofemoral osteoarthritis.

Methods: Fifty-seven patients with femoro-patellar osteoarthritis were allocated to two groups: patients with femoro-patellar functional brace and those with a neoprene knee with a patellar orifice. Both groups underwent clinical treatment of osteoarthritis and used medications daily 1 month before and up to 3 months after brace placement. They were evaluated with the WOMAC and Lequesne questionnaires and performed five times sit to stand test, Timed Up and Go test, and six minutes walk test immediately before and 1 and 3 months after brace placement.

Results: Both groups had improved pain, stiffness, and function with no difference between groups. Drug use decreased in both groups in the first month but increased in the third month. Naproxen use was progressively higher in the control group.

Conclusion: Both knee orthoses improved pain and function and altered drug use only in the first month. Functional knee brace provided analgesia without increased use of naproxen. .

PROFILE OF PATIENTS WITH OSTEOPOROTIC FRACTURES AT A TERTIARY ORTHOPEDIC TRAUMA CENTER.

Acta Ortop Bras 2018 Mar-Apr;26(2):117-122

. Osteometabolic Diseases Group, Instituto de Ortopedia e Traumatologia, Hospital das Clinicas HCFMUSP, Faculdade de Medicina, Universidade de São Paulo, SP, Brazil.

Objective: To evaluate the profile of patients with osteoporotic fractures treated at a tertiary orthopedic hospital.

Methods: Using questionnaires, 70 patients with osteoporotic fractures (OF) were compared with 50 outpatients with multiple osteoarthritis (OA) followed through an outpatient clinic.

Results: The OF group was older (p <0.001), less heavy (p=0.003), had lower BMI (p=0.006), was more likely to be white (p=0.011), was less likely to be married (p=0.008), and had previous falls, previous fractures, old fractures (>1 year), falls in the last 12 months, fractures due to falls, and needed more assistance (p<0.05). They also had lower Lawton & Brody Instrumental Activities of Daily Living scores (p <0.05) and reported less lower limb disability, foot pathology, muscle weakness, hypothyroidism, and vitamin D intake than patients in the OA group. White race, previous falls, and previous fractures increase the risk of osteoporotic fractures by 10.5, 11.4, and 4.1 times, respectively. The chance of fracture dropped 29% for each one-unit increase in Lawton & Brody IADL score. Married participants had fewer fractures than participants with other marital status.

Conclusion: Together, race, marital status, previous falls, foot pathologies, previous fractures, and IADL scores define the profile of patients with osteoporotic fractures. Level of Evidence III; Case control study.

Double femoral osteotomy fixed with a Puddu plate and a retrograde intramedullary nail to treat biapical deformity of the femur.

Rev Bras Ortop 2018 May-Jun;53(3):378-383. Epub 2018 Apr 5.

Departamento de Ortopedia e Traumatologia, Faculdade de Medicina, Universidade de São Paulo (FM-USP), São Paulo, SP, Brazil.

Biapical femoral deformities are challenging to treat. In order to correct concomitant metaphyseal and diaphyseal deformities of the femur, the authors propose a double femoral controlled osteotomy with combined internal fixation, consisting of a Puddu plate and an intramedullary nail. The method was described in two patients. Results were analyzed using a visual analog scale (VAS), the Lysholm score, and SF-36. No complications were found. Complete consolidation of the osteotomies and radiographic alignment correction were achieved. Results were obtained with a minimum follow-up of 66 months. Both patients had improved for pain (VAS from 60 to 40 and from 50 to 20 at reassessment), function (Lysholm score from 78 to 93 and from 55 to 73) and quality of life (SF-36, both mental - from 40.7 to 57.1 in case one and from 24.7 to 59.7 in case two - and physical - from 27.7 to 45.6 and from 28.2 to 46.8). The authors have found that this technique is a reliable, accurate, and reproducible solution for biapical deformities of the femur.

QUALITY OF LIFE IN PATIENTS WITH ROTATOR CUFF ARTHROPATHY.

Acta Ortop Bras 2017 Nov-Dec;25(6):275-278

. São Paulo State Health Technology Assessment Network, São Paul State Department of Health, São Paulo, SP, Brazil.

Objective: To compare quality of life (according to the SF-12) in patients with rotator cuff arthropathy with controls paired by sex and age. Secondary objectives are to compare the groups according to the ASES and VAS scales.

Methods: This cross-sectional study with controls paired by sex and age compared patients with rotator cuff arthropathy with surgical indication for reverse shoulder arthroplasty. The groups were compared according to the SF-12, ASES, and VAS scales.

Results: The groups consisted of 38 individuals, 28 women. The SF-12 demonstrated a significant difference in the physical component, with the cases scoring 31.61 ± 6.15 and the controls 49.39 ± 6.37 (p<0.001). For the mental component, the difference was not significant, with the cases scoring 44.82 ± 13.18 and the controls 48.96 ± 8.65 (p=0.109). The cases scored 7.34 ± 2.11 on the VAS and 31.26 ± 15.12 on the ASES, while the controls scored 0.55 ± 1.31 and 97.53 ± 6.22, respectively (p<0.001).

Conclusion: Patients with rotator cuff arthropathy had poorer results for the physical component of the SF-12 than the controls. They also had poorer functional results according to the ASES scale, and more pain according to the VAS.

The sagital balance in idiopatic and neuromuscular scoliosis.

Acta Ortop Bras 2014 ;22(4):179-82

Universidade de São Paulo, Faculdade de Medicina, Hospital das Clínicas, São Paulo, SP, Brazil, Institute of Orthopedics and Traumatology, Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, São Paulo,SP, Brazil.

Objectives: To describe and compare the distribution of spinopelvic parameters (SPP) in a Brazilian population with idiopathic scoliosis (IS) and neuromuscular scoliosis (NMS), and evaluate the association between pelvic incidence (PI) and lumbar lordosis (LL).

Method: Medical records investigation was performed. Sagital balance angles were measured in patients with neuromuscular and idiopathic scoliosis.

Results: IS SAMPLE MEANS (IN DEGREES): PI 55.55; Sacral Slope (SS) 45.35; Pelvic Tilt (PT) 10.19; Lumbar Lordosis (LL) 43.48; and Thoracic Kyphosis (TK) 32.10. In NMS: PI 53.77; SS 42.31; PT 11.46; LL 49.46; and TK 45.69. No statistically significant differences in PEP distribution were found between the two types of scoliosis (p=0,057). The association between pelvic incidence and lumbar lordosis is low among idiopathic scoliosis (R=0,074) and neuromuscular scoliosis (R=0,274).

Conclusion: PEP measurements in a Brazilian population of idiopathic scoliosis and neuromuscular scoliosis patients are similar to those in the international literature and do not differ statistically between them. The association between LL and PI could not be assessed in this study. Level of Evidence IV, Case Series.
