Filter by:Bone marrow lesions (BMLs) of the knee are common subchondral defects, often associated with pain and functional limitation. Subchondroplasty is a percutaneous procedure in which calcium phosphate is injected inside BML areas, ensuring stability and promoting the deposition of new bone. Primary outcome of this study was to obtain a reduction of the Numeric Rating Scale score of 4 points or more at 6 months follow-up in more than 75% of patients. The secondary outcome was to evaluate the osteoarthritic and bone marrow structure evolution in the months after the procedure.
Objective 1. To evaluate the technique of percutaneous grafting with bone substitute in the knee as to its applicability and technical feasibility. 2. Evaluate the results regarding functional improvement and prevention of the evolution of joint cartilage degeneration. Material and methods Twenty patients from the Knee Group clinic who meet the criteria will be selected. Magnetic resonance imaging will be analyzed on the PACS server. Through the resonance will be performed evaluation of the size of the bone edema in volume and its proportion in relation to the size of the affected condyle or tibial plateau and the cartilage of the femoro-tibial joint. The lesions will then be mapped in the coronal and sagittal plane. Radiographs will be taken in antero-posterior, profile, Rosenberg knee and lower limb views. Evaluation of the patients will be performed by the visual analog pain scale and by the KOOS, IKDC and SF-36v1 indices. Description of Surgical Technique After the mapping the patient will be submitted to the procedure. The procedure consists in the application of a bone substitute based on injectable calcium phosphate in the area of bone edema previously mapped with the aid of radioscopy to guide. After confirming the proper positioning of the guidewire, a trephine is introduced through which the product will be injected. GRAFTYS HBS® (Graftys, Aix en Provence, France) will be used. The procedures will be performed in a surgical center, with conventional antisepsis and asepsis techniques and under spinal anesthesia. The patient will be hospitalized and must be discharged on the first postoperative day. After the procedure the patients will be under partial load as tolerated for two weeks with free range of motion and will start physiotherapy after 2 weeks of the procedure. During hospitalization the patient will receive analgesia with intravenous Dipirone 1g every 6 hours associated with Tramadol 100mg intravenously every 8 hours if severe pain. After discharge the patient will receive analgesia with dipyrone 1g orally every 6 hours associated with Tramadol 100mg orally every 8 hours if severe pain, and Tramadol used by the patient was quantified. Patients will then be re-evaluated at 1, 3, 12, 24 and 48 weeks with the same previous criteria and at 12 months new MRI with the same previous protocol will be performed.
This is a prospective, multi-center, post-market data collection study intended to collect data on the short- and long-term safety and performance of the SCP Procedure.
This is a multi-center, prospective, single-blinded, two-arm study, randomized to include approximately 134 subjects treated with Subchondroplasty (SCP) + Arthroscopy and 67 subjects with arthroscopy alone. The primary objective of this study is to demonstrate superiority of Subchondroplasty with arthroscopy compared to arthroscopy alone for treatment of Bone Marrow Lesions (BMLs) in the knee.
Post Market clinical outcomes study to collect data on the short - and long-term outcomes for subjects who are undergoing or who have undergone the Subchondroplasty (SCP) Procedure in the knee in a standard clinical setting. Outcomes to be assessed include pain medication usage, pain, function, activity levels and patient satisfaction.
Studying long-term changes in a sub-set of patients who undergo the Subchondroplasty procedure including changes in pain, function, and overall health.
The primary aim is to test the reduction of bone marrow edema syndrome after a singular intravenous treatment with Zoledronic Acid within 6 weeks compared to placebo. The volume of the edema is defined as biometric data measured by the use of MRT before and six weeks after treatment. The hypothesis has to be checked whether Zoledronic Acid is efficient in the treatment of painful bone marrow edema. A statistically significant reduction of the edema in the MRT is considered as evidence for efficacy.
