Brief Summary:
The goal of this clinical trial is to evaluate the effectiveness and safety of intra-articular injection of a cross-linked sodium hyaluronate; SEMICAL GEL-B CROSS, in knee osteoarthritis.
Primary objectives: The aim of this study is to obtain short- and long-term clinical data on the performance and safety of intra-articular injection of SEMICAL GEL B-CROSS, produced and marketed by Semical Biosurgery incorporated company, in knee osteoarthritis patients.
It is also aimed to monitoring known adverse events and complications, detecting previously unknown adverse events and complications, to identify and analyze emerging risks based on real-life data. Participants will receive intra-articular injection of either a cross-linked sodium hyaluronate (SEMICAL GEL-B CROSS); or placebo (isotonic saline solution) at baseline, and will be followed-up for one year to compare the effectiveness and safety of the given therapy.

Detailed Description:
The study is a randomized controlled, double-blind, two-armed, single-center and cross-over study. After a maximum screening period of 28 days, patients with Kellgren \& Lawrence Stage II and III knee osteoarthritis will be randomly assigned to one of the two treatment arms on the day of injection, which is considered Day 0. These treatment arms are:
Group 1: Treatment Arm - Cross-linked intra-articular hyaluronic acid (90 mg 3 ml cross-linked hyaluronic acid)
Group 2: Control Arm - Intra-articular isotonic saline solution (3 ml 0.9% isotonic saline) A safety visit will be made 7-10 days after administration of the treatment injection and the injection site will be visually evaluated for local reactions. In addition, an inquiry for injection-related adverse events will also be conducted.
Treatment responses of patients in both groups will be evaluated by a separate researcher blinded to study treatment with predefined objective response criteria.
At the 3rd month visit, the patients in both groups will be crossed-over and those who received a placebo at baseline will receive a hyaluronic acid injection at the 3rd month, while those who receive a hyaluronic acid injection at baseline will receive a placebo at the 3rd month. Efficacy evaluations will continue to be made at every three months for one year.
