Intra-articular Hyaluronan After Arthroscopic Meniscal Surgery

Intra-articular Hyaluronan After Arthroscopic Meniscal Surgery.

The primary objective of this clinical investigation is to determine whether post-arthroscopic treatment with 10 ml of 0.5% sodium hyaluronate (VISCOSEAL® SYRINGE) can relief pain, improve mobility and promote joint recovery, compared to the standard arthroscopy procedure alone, in patients undergoing arthroscopic procedure.

Inclusion Criteria:

• Male and female patients between 18 and 75 years of age.
• Good general health condition.
• Signed written informed consent.
• Patients with necessity for arthroscopic meniscal surgery.
• Ensured compliance of subject over the whole study period.

• Concomitant or previous participation in a clinical investigation within the last 3 months prior to study inclusion.
• Knee joint arthroscopy in study relevant joint within 6 months prior to study inclusion.
• Patients with known hypersensitivity to the investigational device (i.e. active compound and excipients) or any component or procedure used in the study.
• Contraindication for the use of the investigational product or for the scheduled arthroscopy, used anesthesia and post-surgical treatment.
• Concomitant disease of sufficient severity (e.g. uncontrolled diabetes mellitus, carcinoma, etc.), which in the opinion of the investigator, may put the patient at risk when participating in the study, or affect the patient's ability to take part in the study.
• Concomitant disease of sufficient severity at study relevant joint (e.g. known or suspected infection, peripheral neuropathy or presence of hemarthros).
• List of concomitant medications not allowed which interfere with the functional assessments of this study.
• Use of medication contraindicated for arthroscopic surgery.
• Intra-articular treatment with a sodium hyaluronate-based product within the last 6 months or use of corticosteroid containing substance within the last 3 months at study relevant joint.
• Recent history of drug and/or alcohol abuse (within the last 6 months) or patients with severe mental illness or suicidal tendency.
• Pregnant or lactating females.
• Participants of childbearing age (pre-menopausal) who do not accept the use of methods of birth control with pearl index ≤ 1% (i.e. oral contraceptives, vaginal ring, hormone-releasing Intrauterine Device (IUD), implants, depot syringes, hormone patch, double barrier method, tubal ligation, vasectomised partner,…) during the treatment period and the first 4 weeks of follow-up period.
• Subjects having a high probability of non-compliance to the study procedures according to investigator's judgement (like illiteracy, insufficient knowledge of local language).
