About

Chondromalacia patella(CP) is a common cause of anterior knee pain in the population under 50 years of age. 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.

Full description

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. WOMAC value was taken as the primary outcome measure and MRI cartilage values were taken as the secondary outcome measure.

28 participants in 2 patient groups

Control Group
Active Comparator group
Description:
First group (14 people): 4-weeks home exercise program will be given to control group. The exercise program includes quadriceps isometric exercises (holding for 10 seconds, 20 reps), straight leg raises (20 reps holding for 6 seconds), and semi-squatting exercises (20 reps), hip flexors, hamstring and iliotibial band stretching exercises (20-repetitions), strengthening exercises for hip abductors and adductors (holding for 6 seconds with 20 repetitions). These exercises were said to be performed for 30 minutes, once a day, every day for 4 weeks.
Treatment:
Behavioral: Exercise
LP-PRP Group
Active Comparator group
Description:
Second group (14 people): LP-PRP injection and 4-week exercise program will be applied by targeting the suprapatellar bursa. The LP-PRPs to be applied will be obtained by centrifugation of the venous blood taken from the patients by manual methods.
Treatment:
Behavioral: Exercise
Biological: LP-PRP
