- ONE-YEAR RESULTS OF BRACING FOR PATELLO-FEMORAL OSTEOARTHRITIS. PROSPECTIVE RANDOMIZED STUDY(2021) MERINO, Matheus Garcia Lopes; MORALE, Victor; OCAMPOS, Guilherme Pereira; LUZO, Maria Candida Miranda; CAMARGO, Olavo Pires de; REZENDE, Marcia Uchoa deObjective: 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.
- RANDOMIZED PROSPECTIVE STUDY ON THE TREATMENT OF FEMORO-PATELLAR OSTEOARTHRITIS USING BRACING(2019) YAMAMOTO, Gustavo Jum; CAMPOS, Guilherme Pereira; LUZO, Maria Candidade Miranda; SILVA, Cleidneia Aparecida Clemente da; FARIAS, Fabiane Elize Sabino de; REZENDE, Marcia Uchoa deObjective: 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 AND FACTORS THAT DECREASE PREVENTION(2019) XAVIER, Renato Martins; GIAROLA, Ivan Carvalho; CAMPOS, Guilherme Pereira; PLAPLER, Perola Grinberg; CAMARGO, Olavo Fires de; REZENDE, Marcia Uchoa deObjective: 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.
- SELF-MANAGEMENT PROGRAM (PARQVE) IMPROVES QUALITY OF LIFE IN SEVERE KNEE OSTEOARTHRITIS(2022) BISCARO, Raphael carvalho; OCHOA, Pablo gabriel garcia; OCAMPOS, Guilherme pereira; AROUCA, Matheus manolo; CAMARGO, Olavo pires de; REZENDE, Marcia Uchoa deObjective: To evaluate the effects of the self-management program PARQVE in patients with severe knee osteoarthritis (KOA). Methods: Prospective randomized controlled clinical trial with 65 grade IV Kelgren & Lawrence (K & L) KOA patients who were allocated into groups: Control (CG) and Intervention (IG). Both groups received usual care. IG also participated in two days of multi-professional interventions about OA (causes and treatment) and received the program's DVD and book. Standing X-rays were obtained at inclu-sion and Ahlback's classification was registered. Western Ontario and McMaster Universities Index (WOMAC), Numerical Rating Scale (NRS), Lequesne, weight, and body mass index (BMI) were obtained at inclusion, and after 6, 12 and 24 months. Results: Groups were similar at baseline, despite higher WOMAC stiffness scores and a greater number of Ahlback's grade 4 and 5 in the IG. Only the IG improved WOMAC and total functions (p < 0.001) during the study period above 12%, but did not reach the minimal clinically important difference of 20%. Best results were in one year. Non-significant improvements were observed without changes in body composition (P > 0.05). Conclusions: Patients with severe KOA have mild to moderate function and quality of life improvement due to self-management program (PARQVE).
- THE SAGITAL BALANCE IN IDIOPATIC AND NEUROMUSCULAR SCOLIOSIS(2014) BORGES, Paulo Alvim; OCAMPOS, Guilherme Pereira; MANCUSO FILHO, Jose Antonio; LETAIF, Olavo Biraghi; MARCON, Raphael Martus; CRISTANTE, Alexandre FogacaObjectives: 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.
- IMPROVEMENTS IN HIP OSTEOARTHRITIS WITH LAVAGE, TRIAMCINOLONE AND HYLAN G-F20(2020) REZENDE, Marcia Uchoa De; GURGEL, Henrique Melo Campos; OCAMPOS, Guilherme Pereira; CAMPOS, Gustavo Constantino De; FRUCCHI, Renato; PAILO, Alexandre Felicio; PASQUALIN, Thiago; VICENTE, Jose Ricardo Negreiros; CAMARGO, Olavo Pires DeObjective: 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 (01); lavage, triamcinolone, and 4mL of hylan G-F20 (02); lavage, triamcinolone, and 6mL of hylan G-F20 (03). 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 (01, 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 AT A TERTIARY ORTHOPEDIC TRAUMA CENTER(2018) SHU, Michael Minsu; CANHOS, Andre Langes; OCAMPOS, Guilherme Pereira; PLAPLER, Perola Grimberg; CAMARGO, Olavo Pires; REZENDE, Marcia Uchoa deObjective: 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.
- EVALUATION OF MANAGEMENT OF PATIENTS WITH OSTEOPOROTIC FRACTURES BY ORTHOPEDIC RESIDENTS: A CROSS-SECTIONAL OBSERVATIONAL STUDY(2022) OCAMPOS, Guilherme pereira; PERES, Matheus Mendonca; REZENDE, Marcia Uchoa de; AROUCA, Matheus Manolo; CAMARGO, Olavo Pires deObjective: To assess whether residents (R1, R2, or R3 -according to the year of residency) of a tertiary orthopedic service inves-tigate, treat and/or refer the patient with osteoporotic fracture for osteoporosis (OP) treatment and whether this learning is improved over the years of residency. Methods: Residents answered diagnostic and therapeutic questions related to a clinical case of osteoporotic fracture (OF) in 4 settings, which were initial care in the emergency room, at discharge, during out-patient follow-up at 3 and 6 months. Responses were compared between years of residency. Results: Twenty R1, 21 R2, and 19 R3 raised the questions. One resident treated osteoporosis in R1, two in R2, and four in R3. Seventy-five percent of R1, 90.5% of R2, and 68% of R3 referred patients for OP treatment. Over the years, there has been improved prescribing lab tests for osteoporosis (p = 0.028), with 52.6% of third-year residents prescribing adequate lab tests. In the same period, 100% of R3 correctly prescribed prophylaxis for deep vein thrombosis (p = 0.001). Conclusion: There is learning, but not enough, for secondary prevention of FO. Level of Evidence I; Prospective Comparative Study.
- QUALITY OF LIFE IN PATIENTS WITH ROTATOR CUFF ARTHROPATHY(2017) FERREIRA NETO, Arnaldo Amado; MALAVOLTA, Eduardo Angeli; ASSUNCAO, Jorge Henrique; GRACITELLI, Mauro Emilio Conforto; OCAMPOS, Guilherme Pereira; TRINDADE, Evelinda MarramonObjective: 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.
