Filter by:This study aimed to investigate the production of reactive oxygen derivatives (ROS) and reactive nitrogen derivatives (RNT) in female patients with knee OA, and their effects on oxidative stress by evaluating before and after physical therapy in female patients with gonarthrosis who have Kellegren-Lawrence Staging Scale Stage II and III. aimed. To this study; All female cases over the age of 40 who applied to Başkent University Ankara Hospital and were diagnosed with knee OA by a specialist doctor will be included. Method After the cases participating in the study were checked by a specialist physician, the cases that did not prevent them from being included in the study; It will be graded according to the Kellegren-Lawrence Staging Scale. Stage II and III cases will be included in the study. Sociodemographic characteristics of the patients will be recorded before the treatment. 10 sessions of physical therapy program will be applied to the patients. Treatment program 20 minutes Hot pack (HP), 60-100 Hz frequency range, 60 pulse duration and 20 minutes of conventional TENS (Enraf-NoniusBDelftechpark 39, 2600 AV, Delft, The Netherlands) with the patient comfortable feeling and 10 minutes continuous around the knee A home exercise program will be given with ultrasound (Enraf-Nonius-B Delftechpark 39; 1-MHz; 1.5 watts/cm2) to strengthen the muscles around the knees. Those with acute inflammation of the knee joint, those who underwent surgery in the knee joint for any reason or any trauma to the lower extremity, those with a history of uncontrollable high blood pressure, any neurological or vestibular problems, those who have used steroid injections in the last two months, and any For this reason, patients with systemic diseases that will affect the study will be excluded from the study. Staging criteria according to Kellegren-Lawrence Staging Scale; Stage 0: Normal Stage 1: Possible osteophyte Stage 2: Definite osteophyte, suspected narrowing of joint space Stage 3: Moderate osteophyte, definite narrowing Stage 4: Extensive osteophyte, marked narrowing, sclerosis (Kellegren and Lawrence, 1957). Biochemical analyzes: To this study; Blood samples will be taken before and after treatment from a female patient over 40 years old who was diagnosed with knee OA at Başkent University Ankara Hospital. Total antioxidant level (TAS): It will be determined by an automatic measurement method based on the fact that the characteristic color formed by the 2,2'azino-bis (3-ethylbenz-thiazoline-6-sulfonic acid) (ABTS) radical is brightened by the antioxidants in the sample added to the medium (Erel, 2004). Results will be given in mmol Trolox eqivalen/L. Total oxidant level (TOS): will be determined by automatic measurement method (Erel, 2005). The oxidants in the sample have the task of converting the ferrous ion complex to a ferric ion. Ferric ion (Fe3+) formed by oxidation of iron (Fe2+) to its more stable form (Fe2O3) creates color with xylenol orange in acidic environment. The intensity of the color measured spectrophotometrically is related to the total amount of oxidant molecules present in the sample. The measurement is calibrated with hydrogen peroxide (H2O2) and the results will be given as micromolar H2O2 equivalent per liter (µmol H2O2 equiv./L) (Sydow, 1985). Nitric oxide (NO): Serum nitric oxide concentration (Mirand et al, 2001) will be measured in a spectrophotometer according to the method (PowerWawe XS, BioTek, USA). Serum samples will be deproteinized with 10% zinc sulfate. In this method, nitrate was converted to nitrite with Vanadium (III) chloride. It is based on the measurement of the complex diazonium compound as a result of the reaction of nitrite and sulfanilamide N-(1-Naphthy) ethylene diamine dihydrochloride in an acidic medium. High-density lipoprotein (HDL): It will be run in an autoanalyzer using the Biotrol trademark kit and given in mg/dl. The results will be recorded for each individual on the information sheet.
Total knee replacement (TKR) is considered the most effective and safe method of radical treatment of late stages of knee osteoarthritis. A well-known problem of TKR is a severe postoperative pain syndrome, which is observed in more than 50% of patients. Femoral nerve block (FNB) is the "gold standard" for continuous postoperative analgesia after total knee replacement, as it is effective in reducing the frequency of use of opioid analgetics and reduce the duration of hospitalization. At the same time, the negative effect of this method is the motor blockade of the quadriceps femoris muscle which leads to functional impairment and is associated with an increased risk of falling. Adductor canal block (ACB) provides adequate analgesia comparable to femoral nerve block. Moreover, ACB doesn't affect the motor function of the quadriceps femoris muscle. The possibility of enhanced recovery after total knee replacement is the reason to compare single-shot adductor canal block and continuous femoral nerve block.
Evaluation of a new navigation system in computer-assisted total knee arthroplasty.
The purpose of Total Knee Replacement (TKR) is to remove worn cartilage surfaces and replace them with artificial parts of the same shape. TKR can be used in cases of osteoarthritis, inflammatory rheumatism, bone necrosis of the knee or following malformative or traumatic sequelae. Implant alignment is paramount in TKR and the last years have seen a proliferation of alignment techniques following the introduction of computer and robotic-assisted surgery. Among Computer-assisted surgery, the augmented reality-based navigation system can be an option to improve accuracy in orthopaedic surgery. The hypothesis of this study is: the use of augmented reality-based navigation system allows a prosthesis alignment and positioning that is at least as good as with the traditional mechanically aligned technique, and therefore improves knee functional results. This study also aims at assessing the cost-effectiveness of this new technology.
The main objective of this multicentric, prospective and interventional study is to assess the feasibility of multimodal prehabilitation in patients aged 75 years or older with surgical indication for coxarthrosis or severe gonarthrosis
Evaluation of the Impact of dexmedetomidine as an adjunct for local infiltrations analgesia and ultrasound-based regional anaesthesia as pain medication in regard to patients' opioid need the first 48 hours after the total knee replacement operation.
This prospective study was planned to carried out among the patients with grade II and III (Kellgren Lawrence classification) osteoarthritis of the knee attending outpatients clinic to evaluate the effectiveness and safety of viscosupplementation with intra-articular hyaluronic acid injection.
The main objective of this study is to evaluate the benefit of personalized prostheses compared to conventional prostheses on patient satisfaction 24 months after total knee arthroplasty.
This is a non-inferiority study in which the investigators compare two low-dose radiotherapy schemes, which are recommended from DEGRO Clinical Practice Guidelines (3 Gy vs 6 Gy) for the treatment of osteoarthritis and other osteodegenerative disorders. A first randomization will be carried out among the patients included in the study: - Patients in arm A will be treated at 3 Gy (0.5 Gy/fraction, 3 fractions/week), and patients in arm B will be treated at 6 Gy (1 Gy/fraction, 3 fractions/week). - Patients should not know the arm to which they have been randomized. - Once the treatment is finished, patients will be assessed at 8 weeks. If pain does not improve, a re-irradiation will be performed. If the patients were treated with 3 Gy a new randomization will be performed (3 vs 6 Gy again). If the patiens were treated with 6 Gy they will be re-irradiated with 6 Gy again. The investigators will analyze the results obtained depending on the dose received and depending on the location of the treatment.
The Investigators would like to compare multiradius and single-radius total knee arthroplasty using with association between sagittal patellar offset and anterior knee pain in subjects having undergone bilateral total knee replacement.
