About this trial

This is an interventional treatment trial for Osteoarthritis focused on measuring Arthritis, Osteoarthritis, Arthroplasty

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Subjects that need an ankle joint replacement due to arthritis or failed prior fusion.
  • Subjects who have failed standard conservative management of their ankle condition

Exclusion Criteria:

  • Class IV or higher anesthetic risk
  • Subjects who are not able to comply with the study procedures
  • Known contraindications to joint replacement such as active infection, complete talar necrosis, insufficient quality of bone stock, ligament laxity, severe osteopenia, Charcot's arthropathy
  • Unwilling to be followed for 5 years

Outcomes

Primary Outcome Measures

Survivorship of Salto Talaris Ankle Implant
Count of participants without a failed ankle arthroplasty. Ankle arthroplasty will be considered as failed if the implant is revised or removed and the ankle fused.

Secondary Outcome Measures

The American Orthopaedic Foot and Ankle Society (AOFAS) Score
AOFAS ankle evaluation form is a commonly used standardized assessment of foot and ankle function divided into three anatomic regions. The scale used for this study will be the Ankle-Hindfoot Scale that ranges from 0 to 100. A score of 100 points is the maximum for a patient presenting in excellent condition. The score decreases as pain, limited range of motion, daily activities, joint instability, and alignment are assessed.

5. Study Description

Brief Summary
This post market outcome study will look at the therapeutic results of the Salto Talaris Anatomic ankle prosthesis. The study population will consist of patients who will undergo an ankle arthroplasty procedure with a Salto Talaris ankle implant. An analysis will be conducted of the results, complications and revisions of this prosthesis based on the etiology for which the ankle arthroplasty was performed.
Detailed Description
This is a prospective, multi-center study that will capture the therapeutic results of the Salto Talaris Anatomic ankle prosthesis in the treatment of various ankle afflictions.

Primary Outcome Measure Information:
Title
Survivorship of Salto Talaris Ankle Implant
Description
Count of participants without a failed ankle arthroplasty. Ankle arthroplasty will be considered as failed if the implant is revised or removed and the ankle fused.
Time Frame
10 years
Secondary Outcome Measure Information:
Title
The American Orthopaedic Foot and Ankle Society (AOFAS) Score
Description
AOFAS ankle evaluation form is a commonly used standardized assessment of foot and ankle function divided into three anatomic regions. The scale used for this study will be the Ankle-Hindfoot Scale that ranges from 0 to 100. A score of 100 points is the maximum for a patient presenting in excellent condition. The score decreases as pain, limited range of motion, daily activities, joint instability, and alignment are assessed.
Time Frame
Postoperatively at 3 months, 6 months, 1 year, 2 years, 3 years, 4 years, 5 years, 8 years, and 10 years
Other Pre-specified Outcome Measures:
Title
The Foot Function Index (FFI)
Description
FFI is a specialized questionnaire answered by the patient. The questionnaire consists of three parts used to report clinical scores for the domains of activity limitation, function, and disability in patients with foot and ankle conditions. Each item rated on a 0 - 10 Likert scale. 0 represents no pain/disability, and 10 represents the worst pain imaginable/severe disability for each item. Higher scores indicate decreased function.
Time Frame
Postoperatively at 3 months, 6 months, 1 year, 2 years, 3 years, 4 years, 5 years, 8 years, and 10 years
Title
The Foot and Ankle Ability Measure (FAAM)
Description
FAAM is a region-specific subject questionnaire to evaluate activities of daily living and sports. Answers for both scales are based on a Likert scale (4-0) of: 4 - no difficulty 3 - slight difficulty 2 - moderate difficulty 1 - extreme difficulty 0 - unable to do Patients are asked to answer each question with a single response that most clearly describes their condition. Patients are asked to mark not applicable (N/A) if the activity in question is limited by something other than their foot or ankle. A higher score indicates a higher level of physical function.
Time Frame
Postoperatively at 3 months, 6 months, 1 year, 2 years, 3 years, 4 years, 5 years, 8 years, and 10 years
