- Brief Summary
Ankle arthritis is associated with debilitating pain and chronic disability. For the treatment of severe ankle arthritis, total ankle arthroplasty (TAA) is one treatment option. Postoperative pain management in joint arthroplasty is an ongoing and relevant issue. The purpose of this study is to examine if differences exist in postoperative pain control, overall patient satisfaction, and use of narcotics using an intra-articular injection in the operating room compared with a peripheral nerve block in patients undergoing TAA.
- Detailed Description
This is a two-arm, prospective, randomized, controlled clinical study. Use of intra-articular injections in TAA are not widely reported in literature; however, they are commonly used during total knee arthroplasty's (TKAs). The purpose of this study is to examine if differences exist in postoperative pain control, overall patient satisfaction, and use of narcotics using the intra-articular injection compared with a peripheral nerve block in patients undergoing TAA. Results will contribute to the literature for the best surgical practice for pain management following a TAA for ankle arthritis.
Patients will be randomized to receive one of the following interventions for pain control in the operating room:
1. Intra-articular Injection
2. Preoperative Peripheral Nerve Block:
The study aims are:
* Aim 1: Determine if intra-articular injection as source of pain control for TAA lowers postoperative pain as measured by self-reported narcotic use and pain vs. the peripheral nerve block.
* Aim 2: Evaluate differences in functional outcomes and health related quality of life between intra-articular injections and peripheral nerve block as reported by pre- and post-operative patient questionnaires
Patients who consent to participate will complete study activities pre-operatively, and at 2 weeks, 6 weeks, and 3 months post-operatively.

Group Intervention Description Intra-articular injection Intra-articular injection Intra-articular injection at the completion of TAA procedure. Peripheral nerve block Peripheral nerve block Pre-operative peripheral nerve block.
- Primary Outcome Measures
Name Time Method Total narcotic use in morphine equivalents Up to 3 months post-operatively Narcotic dose and frequency captured through patient diary; used to calculate morphine equivalents.
Self-reported pain captured with a visual analog pain scale Up to 3 months post-operatively Measures self-reported pain between 0 (no pain) and 100 (extreme pain)
- Secondary Outcome Measures
Name Time Method Time to narcotic discontinuation Up to 3 months post-operatively Number of days narcotics were taken for post-operative pain control
Foot and Ankle Ability Measure (FAAM) Up to 3 months post-operatively Measures self-reported outcomes accessing physical function for individuals with foot and ankle related impairments.
American Orthopaedic Foot and Ankle Society (AOFAS) Ankle Hindfoot Score Up to 3 months post-operatively Grades ankle, subtalar, talonavicular, and calcaneocuboid joint levels in terms of pain (40 points), function (50 points), and alignment (10 points); 100 points possible sub-scores are summed, higher indicates better outcome.
Veterans Rand (VR) 36 item Health Survey Up to 3 months post-operatively VR-36 Consists of select items from eight concepts of health in the VR-36, measuring health-related quality of life, and differences in disease burden.
