Can a Three-Component Prosthesis be Used for Conversion of Painful Ankle Arthrodesis to Total Ankle Replacement?

Can a Three-Component Prosthesis be Used for Conversion of Painful Ankle Arthrodesis to Total Ankle Replacement? Clin Orthop Relat Res. 2017 Apr 19;: Authors: Preis M, Bailey T, Marchand LS, Barg A Abstract BACKGROUND: In patients with painful ankle arthrodesis, the surgical treatment is challenging, and may include takedown of ankle arthrodesis and conversion to a total ankle replacement (TAR). This procedure is technically demanding given the altered anatomy after arthrodesis. Few studies have evaluated TAR in the setting of prior arthrodesis. QUESTIONS/PURPOSES: (1) What intraoperative and perioperative complications were observed in patients who underwent conversion of an ankle arthrodesis to a TAR? (2) Was durable fixation achieved at short term, and what was the alignment of the components? (3) What subsequent surgical procedures were performed, including revisions? (4) What improvements were observed in pain, tibiotalar range of motion (ROM), and quality of life? METHODS: Between January 2007 and December 2014, 18 patients with a painful ankle arthrodesis underwent conversion to TAR at our tertiary referral center. During this period, the indications for conversion of ankle arthrodesis to TAR were tibiotalar nonunion or malunion after attempted arthrodesis in patients who declined revision ankle arthrodesis. The goal of revision surgery was to help patients regain hindfoot mobility and to decrease pain. During the study period, all patie...

This study aims to present our clinical outcomes of severe AA treated by ADA. Patient concerns: A 53-year-old man suffered right ankle sprain 10 years ago, endured right ankle pain and limited movement for 6 years. Diagnosis: The patient was diagnosed as severe AA. Interventions: He received ankle distraction arthroplasty. No adjuvant procedures were performed. The visual analog scale (VAS), the American Orthopaedic Foot and Ankle Society (AOFAS) score, the short-form (SF)-36 physical component summary (PCS) score and ankle activity score (AAS) were recorded to access the clinical outcomes pre- and postoperatively...

Conclusion: Awareness of this uncommon manifestation would help differential diagnosis of periostitis and could help decrease the patient's anxiety. It should also be noted that periosteal reactions by benign entities could cause aggressive-looking periosteal reactions in post-operative regions.

The objective part of the Knee Society Score (KSS), the hip –knee–ankle angle (HKA), the tibial mechanical angle (TMA) and femoral mechanical angle (FMA) were recorded preoperative and four months postoperative. Leg alignment was classified as neutral (HKA = 180° ± 3°), varus (HKA   183°). Furthermore, patellar tracking was determined on skyline view radiographs and adverse events were recorded. Implant survival rate was determined with the Kaplan–Meier method. Patient-reported outcome measures (PROMs) were pain, satisfaction, overall ...

We describe, in this article, the hinged joint distraction technique. A total of 50 patients with posttraumatic ankle osteoarthritis with a mean age of 40.0±8.5 years were included in a prospective randomized study: 25 patients in ankle debridement alone group and 25 patients in debridement and hinged ankle distraction group. The mean follow-up was 46±12 months (range: 36 to 78 mo). The clinical and radiographic outcomes were evaluated at the 6-month and 3-year follow-up using the Visual Analog Scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score, SF-36 quality of life score,...

LoganAbstractThe purpose of this study is to report the outcome of the conversion of a first metatarsophalangeal (MTP) joint arthrodesis to an interpositional arthroplasty with an acellular dermal matrix for a chronic nonhealing first ray wound. To our knowledge, this is the first case report converting a first ray arthrodesis to an interpositional arthroplasty to heal a chronic ulceration. A 78-year-old female developed a chronic neuropathic ulceration under the first metatarsal head ...

We report 100% survivorship of the implant at a mean follow-up of 4.9 years. Compared with preoperative levels, all clinical outcome scores showed significant improvement at the 1-year, 2-year, and 5-year and longer follow-up. The mean clinical ROM improved from 27.7° ± 10.7° preoperatively to 40.0° ± 12.3° at the 2-year follow-up (p

Publication date: Available online 6 April 2019Source: The Journal of Foot and Ankle SurgeryAuthor(s): Sarah Johnson-Lynn, Malik SiddiqueABSTRACTTotal ankle replacement (TAR) is an established technique for the treatment of end-stage ankle arthritis. The aims of TAR include pain relief, preservation of tibiotalar movement, protection of adjacent joints, and restoration of anatomic alignment in the coronal and sagittal planes. The aims of this study were to determine the relative importance of pre- and post-TAR coronal and sagittal balance on postoperative patient-reported outcome measures (PROMs). A total of 101 ankles in ...

AbstractPost ‐traumatic osteoarthritis (PTOA) of ankle joints results in pain and reduced joint function. Ghrelin, a 28‐amino‐acid polypeptide, has been previously identified as the first cognate natural ligand that binds to the growth hormone secretagogue receptor. In the present study, ghrelin has been v alidated to exert cartilage‐protective and anti‐inflammatory effects. The current study was aimed at investigating the potential role of the levels of serum and synovial fluid (SF) ghrelin on the severity of disease in patients suffering from ankle PTOA. Ninety‐seven patients with ankle osteoa rthritis who re...
