Decreased ankle dorsiflexion is common after injury and may result in patient complaints of stiffness and subsequent injury. The weight-bearing lunge test (WBLT) is a simple clinical measure of dorsiflexion. Previous study has defined a 2.0cm side-to-side discrepancy in WBLT as likely significant. With review of current literature, ankle stiffness is a concept largely undefined; we aim to relate patient complaints of stiffness to WBLT.

This was a population-based inception cohort with longitudinal follow-up. Patients between ages 18–65 receiving surgical fixation for ankle fracture were screened. Pilon/plafond fractures, bilateral injuries, or polytrauma were excluded. At 6-weeks, 6-months, and 1-year WBLT was measured along with non-weight-bearing goniometry; and an Olerud-Molander ankle score completed.

155 patients were recruited (90 female, 65 male; mean age 42, range 20–67). 47% of injuries were unimalleolar, 17% bimalleolar, and 36% trimalleolar; 35% received syndesmotic fixation. 89% of patients reported feeling stiff at 6-weeks, 82% at 6-months, and 74% at 1-year. 98% of patients had ≥2.0cm discrepancy of WBLT at 6-weeks, 78% at 6-months, and 72% at 1-year. Different thresholds of WBLT (larger discrepancy or absolute negative measurement) had worse correlation with patient reported stiffness.

Our population had high incidence of stiffness at 1-year. The proportion of patients complaining of stiffness after ankle fracture was similar to that measured with ≥2.0cm discrepancy of WBLT. This is the first study that we are aware of that relates the WBLT and the previously reported threshold of 2.0cm to stiffness. This measurement may give clinicians a better objective idea regarding patient perception of a “stiff” ankle. Reducing side to side discrepancy in range of motion should be considered in rehabilitation rather than total range of motion.

Chronic postsurgical pain (CPSP) can occur after elective mid/hindfoot and ankle surgery. Effective treatment approaches for CPSP in this population have not been extensively investigated. The impact of multimodal strategies on CPSP following elective mid/hindfoot surgery is unknown due to both the heterogeneity of acute pain management and the lack of a recognized definition specific to this type of surgery. This study aimed to identify and evaluate current pain management strategies after elective mid/hindfoot and ankle surgery.

We conducted a systematic review under Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Three databases (MEDLINE, Embase and Cochrane Library) were electronically searched for English studies published between 1990 and July 2017. Reference lists of relevant systematic reviews were also manually searched. Comparative studies of adults undergoing elective mid/hindfoot and ankle surgery were included. Two reviewers independently reviewed studies and assessed their methodological quality.

Of 1,159 studies, seven high-quality randomized controlled trials met our inclusion criteria. Though all studies examined regional anesthesia techniques, intervention heterogeneity precluded meta-analysis. Participants were typically followed up to 48 hours post-operatively. Interventions effective at reducing postoperative pain and/or opioid consumption included inserting popliteal catheters under ultrasound instead of nerve stimulation guidance, infusing perineural dexamethasone, bupivacaine, or ropivacaine perioperatively, and adding a femoral catheter infusion to a popliteal catheter infusion. Only one study assessed pain six months following elective mid/hindfoot and ankle surgery, demonstrating significant pain reduction with activity with the addition of a femoral to popliteal catheter infusion.

There is an overwhelming lack of evidence regarding CPSP and its management for patients undergoing elective mid/hindfoot and ankle surgery. Although specific regional anesthesia techniques and adjuncts may be effective at reducing in-hospital pain and opioid consumption after elective mid/hindfoot and ankle surgery, our systematic review identified only seven studies addressing multimodal pain management in this population. Further comparative studies with longer-term follow-up are required.

Chronic postoperative pain (CPP) can occur in elective mid/hindfoot and ankle surgery patients. Multimodal pain management has been reported to reduce postoperative pain and opioid use, which may prevent the development of CPP. However, few studies have examined the impact of multimodal pain management strategies on CPP following complex elective mid/hindfoot and ankle surgery. The purpose of this study was to 1) evaluate current pain management strategies and 2) determine current definitions, incidence, and prevalence of CPP after elective mid/hindfoot and ankle surgery.

Three databases (MEDLINE, Embase and Cochrane Library) were manually and electronically searched for English language studies published between 1990 and July 2017. For the first aim, we included comparative studies of adults undergoing elective mid/hindfoot and ankle surgery that investigated pre-, peri- or postoperative pain management. For the second aim, we included observational studies examining CPP definition, incidence, and prevalence. Two reviewers independently screened titles and abstracts, followed by full texts. Conflicts were resolved through discussion with a third reviewer. Reviewers also independently assessed the quality of studies meeting inclusion criteria using the Joanna Briggs Institute Critical Appraisal Checklist.

For the first aim, 1159 studies were identified by the primary search, and seven high quality randomized controlled trials were included. Ankle arthroplasty or fusion and calcaneal osteotomy were the most common procedures performed. The heterogeneity of study interventions, though all regional anesthesia techniques, precluded meta-analysis. Most investigated continuous popliteal, sciatic and/or femoral nerve blockade. Participants were typically followed up to 48 hours postoperatively to examine postoperative pain levels and morphine consumption in hospital. Interventions effective at reducing postoperative pain and/or morphine consumption included inserting popliteal catheters using ultrasound instead of nerve stimulation guidance, perineural dexamethasone, and adding continuous femoral blockade to continuous popliteal blockade. Using more than one analgesic was generally more effective than using a single agent. Only two studies examined longer term pain management. One found no difference in pain levels and opioid consumption at two weeks with perineural or systemic dexamethasone use. The other found that pain with activity was significantly reduced at six months postoperatively with the addition of a femoral catheter infusion to a popliteal catheter infusion. For the second aim, only two studies of the 747 identified were selected. One prospective observational study defined CPP as moderate-to-severe pain at one year after foot and ankle surgery, and reported 21% and 43% of patients as meeting their definition at rest and with activity, respectively. The other study was a systematic review that reported 23–60% of patients experienced residual pain after total ankle arthroplasty.

There is no standardized definition of CPP in this population, and incidence and prevalence are rarely reported and vary largely based on definition. Although regional anesthesia may be effective at reducing in-hospital pain and opioid consumption, evidence is very limited regarding longer-term pain management and associated outcomes following elective mid/hindfoot and ankle surgery.

Introduction

A randomized clinical trial of first metatarsophalangeal (MTP) joint hemiarthroplasty with a synthetic cartilage implant demonstrated equivalent pain, function and safety outcomes to first MTP joint arthrodesis at 2 years. The implant cohort continues to be followed under an extension of the original study and we report on prospectively determined 5+ year outcomes for subjects assessed to date.

Purpose

The failure rate of total ankle arthroplasty (TAA) in rheumatoid patients may be higher than in osteoarthritis patients due to the medications used to treat rheumatoid arthritis and the comorbidities associated with this disease. The purpose of this study was to prospectively look at the intermediate-term outcomes of TAA in patients with rheumatoid arthritis and to compare the results to a matched cohort of patients with ankle osteoarthritis undergoing TAA.
