Overview
The goal of this clinical trial is to evaluate the effectiveness of STABHA, high-concentration glucose water, and saline injections in treating knee osteoarthritis with medial collateral ligament lesions. This prospective, double-blind, randomized trial will recruit 51 patients from the Shin Kong Hospital Rehabilitation Department. The main questions it aims to answer are: 1. Do STABHA or high-concentration glucose water injections provide better pain relief and improved knee function compared to saline? 2. What side effects do participants experience with these treatments? Participants will be randomly divided into three groups: STABHA, high-concentration glucose water, and saline. In addition to routine intra-articular hyaluronic acid injections, each group will receive two ultrasound-guided injections of their assigned treatment into the medial collateral ligament of the knee, with a two-week interval. All participants will also undergo a 4-week physical therapy program. Participants will: 1. Receive two ultrasound-guided injections over two weeks. 2. Undergo 4 weeks of physical therapy. 3. Return for follow-up assessments at 1 and 3 months, including the WOMAC osteoarthritis index, pain score, KOOS knee outcome score, knee range of motion, and knee ultrasound examination.
