[Total knee replacement due to grade IV gonarthrosis]

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering
• Reconstructive Surgery

Background:

• Severe gonarthrosis, often secondary to varus angular deformity, significantly impacts knee function.
• Total knee arthroplasty (TKA) is a common surgical intervention for end-stage knee osteoarthritis.

Purpose of the Study:

• To describe the clinical evolution of patients undergoing TKA for gonarthrosis secondary to varus angular deformity.
• To assess surgical outcomes and complication rates in this specific patient cohort.

Main Methods:

• A descriptive trial involving patients who underwent TKA for varus deformity gonarthrosis.
• Data collected included patient demographics, surgical approach, prosthesis type, gait, infection, vascular status, pain, and pre/post-operative angular deformity.

Main Results:

• The study reviewed 13 patients (69.2% male, mean age 72.38 years).
• Significant reduction in average angular deformity from 15.77° pre-surgery to ≤5° post-surgery (p=0.00).
• One patient (7.6%) experienced infection; no vascular complications were noted. Most patients required assistive devices for ambulation initially.

Conclusions:

• TKA is effective in correcting varus angular deformity in gonarthrosis patients.
• Clinical evolution and complication rates are comparable to those reported in the broader literature for TKA.
