Racing performance in standardbred trotters with chronic synovitis after partial arthroscopic synovectomy in the metacarpophalangeal, metatarsophalangeal and intercarpal (midcarpal) joints.
Abstract: Chronic synovitis may cause recurring lameness in competing race horses. Forty-five standardbred horses with recurring lameness secondary to chronic synovitis were studied. Arthroscopic synovectomy was performed in 32 metacarpo-/metatarsophalangeal joints and in 28 intercarpal joints of horses that had previously been treated unsuccessfully with commonly used intraarticular medication The outcome of the synovectomy was evaluated by comparing racing performance before and after surgery. The synovial membrane was microscopically characterized as chronic synovitis of varying severity. Racing performance was expressed by racing results including average earnings/race, place 1-3, best time and racing index. Fourteen of 19 horses with chronic synovitis of the intercarpal joint performed at an equal or higher racing level after synovectomy. Twenty-one of 26 horses with lameness secondary to chronic synovitis in the fetlock joint had an equal or higher racing capacity after synovectomy. The results of this study indicates that arthroscopic synovectomy in combination with rest is an effective method in the treatment of chronic synovitis when conventional intraarticular medication has failed.

The study reveals the benefits of arthroscopic synovectomy on standardbred racehorses suffering from chronic synovitis that causes recurring lameness. Results indicate an improvement or maintenance of racing performance after the surgery, demonstrating its effectiveness as a treatment when traditional medication fails.
Study Methodology and Participant Information
- The study focuses on 45 standardbred racehorses showing recurring lameness due to chronic synovitis, a condition involving inflammation of the synovial membrane within the joints.
- Among these, arthroscopic synovectomy, a minimally invasive surgical procedure to remove inflamed synovial tissue, was performed on 32 metacarpo-/metatarsophalangeal joints and 28 intercarpal joints. These horses had not responded to traditional intraarticular medication.
Evaluation and Results
- The effectiveness of the synovectomy was determined by comparing the racehorses’ performance before and after surgery. Performance metrics included racing results, average earnings per race, placing in the top three, best time, and racing index.
- Fourteen out of 19 horses with chronic synovitis of the intercarpal joint showed equal or increased racing performance after the synovectomy.
- Out of 26 horses with lameness due to chronic synovitis in the fetlock joint, 21 demonstrated equal or improved racing capabilities post-surgery.
Summarized Conclusion
- The findings of the study suggest the effectiveness of arthroscopic synovectomy when combined with rest, in treating chronic synovitis.
- This surgical intervention appears beneficial when conventional intraarticular medication has been unsuccessful, helping maintain or improve the racing performance of standardbred racehorses.
