Total ankle arthroplasty (TAA) significantly improves gait function and reduces pain in patients with end-stage ankle arthritis. While function doesn't reach healthy levels, TAA offers clinically meaningful improvements over preoperative status.
Area of Science:
- Orthopedics
- Biomechanics
- Rehabilitation Medicine
Background:
- End-stage ankle arthritis causes significant functional disability.
- Gait abnormalities are a key indicator of this disability.
Purpose of the Study:
- To evaluate the functional gait improvements following total ankle arthroplasty (TAA).
- To compare postoperative gait parameters with preoperative function in TAA patients.
Main Methods:
- Gait analysis was performed on patients before and after TAA.
- Key gait parameters including step length, cadence, velocity, motion, power, and moment were measured.
Main Results:
- TAA led to statistically significant improvements in all measured gait parameters compared to preoperative function.
- Improvements were observed in step length, cadence, velocity, ankle/hip/knee motion, and ankle power/moment.
- Patients reported significant pain relief and increased satisfaction post-TAA.
Conclusions:
- Total ankle arthroplasty provides clinically meaningful and statistically significant functional gait improvements for end-stage ankle arthritis.
- While functional outcomes do not match healthy controls, TAA offers substantial benefits over the preoperative state.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
