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...

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...

ConclusionsCutting guide technique group did not yield lower incidence of anterior knee pain. More outliers of lateral patellar tilt were observed in the freehand technique group. Overall, all patients in both groups had identical results in terms of patellofemoral functional capacity, clinical outcomes, and other radiographic results.

AbstractPost-traumatic arthritis (PTA) is characterized by the deterioration of articular cartilage temporally associated with an articular injury. With a paucity of literature comparing joint preservation techniques, we performed a systematic review of the literature intending to describe and summarize the results of ankle distraction arthroplasty as it compares with studies on tibio-talar microfracture, allograft, and autograft for ankle joint preservation in the post-traumatic population under 50  years of age. Research databases were searched and abstracts screened for relevance on our topic of interest. Abstracts...

CONCLUSIONS An appropriately chosen type of the implant, a fitting indication and a correctly applied implantation technique can lead to the desired good outcome. The first MTP joint replacement should be indicated after careful consideration since the management of a potential joint replacement failure can often be very technically challenging and quite mutilating for the patient. The mid-term outcomes of the Medin a.s. first MTP implant seem to be promising. It will, however, be necessary to wait for long-term outcomes in order to evaluate the final benefits of this type of implant in patients with hallux rigidus. Key wo...

Primary osteoarthritis of the first metatarso-phalangeal joint (MTP-1) is common and gives clinical symptoms already in the fourth and fifth decade of life. Definition of the clinical entity is a painful dorsal collision phenomenon, a dorsal bunion, pain from shoe wear, and severely diminished dorsiflexion in the MTP-1 joint. Lateralization of the loading pattern over the lateral side of the foot and off loading of the great toe is typical and often leads to metatarsalgia. Depending on the radiographic grade of osteoarthritis (1 –4) [1], the options for surgical treatment are cheilectomy or osteotomy (grades 1–...

Rationale: High tibial osteotomy (HTO) has been used widely for medial compartment knee osteoarthritis to correct the deformity and relieve symptoms, especially in young patients who are willing to maintain the high activity level. However, the change of bone morphology, ligament imbalance, limb malalignment, and other complications may influence the short-term outcomes of HTO. Some cases may even require conversion to TKA shortly after HTO because of the loss of correction or pain due to accelerated osteoarthritis. Patient concerns: A 43-year-old female patient presented with persistent pain of both the left knee and the...
