Abstract:

Objective

To investigate the clinical effectiveness of multiple joint arthroplasty in the treatment of patients with severe ankylosing spondylitis.

Methods

A retrospective analysis was conducted on 18 patients at the Department of Orthopedics of the Second People's Hospital of Shenzhen between January 2015 and December 2020. Inclusion criteria: patients of severe AS with dysfunction of hip and knee underwent primary total knee and hip replacements; patients followed postoperative rehabilitation training according to the instruction and had complete medical records. The patients who were lost to follow up or followed up less than three months were excluded. A total of 40 hip and/or knee replacements were performed based on the patient's condition. The preoperative and postoperative joint functional scores and postoperative complications of the patients were recorded. The efficacy of surgery and improvement of the quality of life were evaluated.The t test was used to compare the functional improvement before and after surgery.

Results

All the patients had an average follow-up time of (31±12) months. The HSS knee score was (33±4) before the surgery, and was improved to (67±5) at one year after the surgery; the difference was statistically significant (t=20.638, P<0.05). The Harris hip score was (16±5) before the surgery, and was improved to (59±7) at one year after surgery; the difference was statistically significant (t=37.181, P<0.05). The mobility of knee and hip improved after the surgery(t=18.096、48.908, both P<0.001). None of the patients had experienced any complications such as joint dislocation, infection, or fracture.

Conclusions

Total knee and hip replacements are an effective treatment for lower limb joint disease in patients with ankylosing spondylitis. It effectively relieves joint pain, improves joint function, and improves quality of life and satisfaction of patients.
