Filter by:The knee pain status of the patients who are followed in the rheumatology special branch of the Physical Medicine and Rehabilitation Outpatient Clinic and who meet the inclusion criteria will be questioned. In patients with or without knee pain, the cartilage thickness measurement of the knee joint will be measured from 3 points by ultrasound. At the same time, Quadriceps and Hamstring muscle thickness measurements of the patients will be made from the midpoints where the muscle thickness is the highest. The physician who performed the ultrasonographic measurements of the knee pain status of the patients does not know.
Increased risk of osteoarthritis (OA) has been previously demonstrated in patients with lower limb amputation. Although there are many studies on knee joint of intact limb of amputees in the literature, the number of studies on intact foot and ankle is extremely limited. The primary aim of the study is to compare the intact talar cartilage, tibialis anterior and gastrocnemius muscle thickness measurements of traumatic unilateral transtibial amputee patients with that of healthy individuals using ultrasound. The secondary aim is to investigate the relationship between cartilage and muscle thickness measurements with clinical parameters.
The research questions of this study are; 1. Is platelet rich plasma (PRP) treatment effective in knee osteoarthritis (OA)? 2. What are the indications for PRP treatment? 3. Which patients are the most suitable for the PRP treatment method? 4. How does age, Body Mass Index (BMI), lower extremity mechanical axis angle and OA stages affect the success of the PRP treatment? 5. Is there any advantage of multiple PRP doses? 6. What is the therapeutic effect of placebo? This study was designed to find answers of these questions. The hypotheses of this study are; "PRP treatment is more effective than placebo; PRP treatment effectiveness decreases with age and advanced stages of OA; BMI is a factor that negatively affects the treatment effectiveness of the PRP; as the mechanical axis angle of the lower limb increases, it will adversely affect the effectiveness of PRP therapy; multiple dose of PRP affects the effectiveness and duration of PRP as positively compared to single dose of PRP". The primary purpose of this study; to prove the effectiveness of PRP treatment on knee pain and functions in patients with knee OA by comparing it with the placebo control group. Secondary purposes of this study; to understand the effect of age, BMI, OA grade and lower limb mechanical axis angle on PRP effectiveness. This study, designed as a randomized, double-blind and placebo control group, with a high level of scientific evidence. Thus, it will be scientifically possible to find answers to the investigators research questions and to prove the investigators hypothesis.
The purpose of this study was to investigate the potential ability of autologous conditioned serum (ACS) to decrease the pain and improve the joint functionality in patients affected by knee osteoarthritis (OA).
The purpose of this study is to evaluate teriparatide (TP) as a chondroregenerative therapy for human knee osteoarthritis (OA). The central hypothesis to be tested is that TP supports structural modification of the joint and improves biomarker, functional and patient-reported measures of knee OA.
Recently an articular cartilage repair has been given much attention in the orthopaedic field. Cartilage regeneration capacity is very limited. Optimal approach seems to be a delivery of natural growth factors. Autologous platelet-rich plasma (PRP) contains proliferative and chemoattractant growth factors. The objective of the present study was to determine if PRP can increase tibiofemoral cartilage regeneration and improve knee function.
