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.

Condition or disease Intervention/treatment Phase
Osteoarthritis Rheumatoid Arthritis Post-Traumatic Arthritis Septic Arthritis Prior Ankle Fusion Device: Salto Talaris Ankle Not Applicable

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.

Arm Intervention/treatment
Salto Talaris Ankle
This is an Implant Registry of the approved Salto Talaris Ankle replacement device
Device: Salto Talaris Ankle
Salto Talaris Anatomic Ankle total joint prosthesis
Other Name: Salto Talaris

Primary Outcome Measures :
  1. Survivorship of Salto Talaris Ankle Implant [ Time Frame: 10 years ]
    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 :
  1. The American Orthopaedic Foot and Ankle Society (AOFAS) Score [ Time Frame: Postoperatively at 3 months, 6 months, 1 year, 2 years, 3 years, 4 years, 5 years, 8 years, and 10 years ]
    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.

Other Outcome Measures:
  1. The Foot Function Index (FFI) [ Time Frame: Postoperatively at 3 months, 6 months, 1 year, 2 years, 3 years, 4 years, 5 years, 8 years, and 10 years ]
    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.

  2. The Foot and Ankle Ability Measure (FAAM) [ Time Frame: Postoperatively at 3 months, 6 months, 1 year, 2 years, 3 years, 4 years, 5 years, 8 years, and 10 years ]

    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.
