CP is characterized by softening or varying degrees of damage to the patellar cartilage. The positive effects of leukocyte poor-platelet rich plasma (leukocyte poor-platelet rich plasma, LP-PRP) on cartilage repair and degenerative findings are known. However, there is no randomized controlled study on this subject in CP. The aim of this study is to investigate the effect of LP-PRP on pain, function, walking distance and magnetic resonance imaging (MRI) findings in CP patients.The study is the first to investigate the effect of LP-PRP on cartilage measurement with MRI in Chondromalasia Patella. Patients with anterior knee pain who applied to the physical therapy and rehabilitation outpatient clinic of Kayseri City Hospital, patients with Chondromalacia patella in MRI will be included in the study. A total of 40 patients will be randomized into 2 groups. The exercise program will be applied to both groups as a home program for 4 weeks.', 'detailedDescription': 'A randomized, prospective, controlled study included 28 patients with MRI stage 2 and above Chondromalasia Patella findings. The patients were randomized into 2 groups, group 1 (the group in which 2 doses of suprapatellar bursa were injected with 2 doses of 3 cc LP-PRP at 1-week intervals and a 4-week home exercise program was given) and group 2 (the control group, the group given a 4-week home exercise program). Patients were tested on the Visual Analogue Scale (VAS) day, night and motion, Western Ontario McMaster Universities Osteoarthritis Index (WOMAC), 6-minute walk test (6MWT) at baseline,1st week, 4th week and 12th week and cartilage thickness, including defective cartilage thickness, and Chondromalasia Patella Outerbridge Staging were evaluated on MRI at baseline and 12th week.
