REVIEW
D Pape, A Hoffmann, R Seil
Physiologic alignment of the human lower leg is well defined. The etiology for malalignment comprises constitutional, degenerative and posttraumatic conditions. Osteotomies around the knee can correct the malalignment, provided that the origin of deviation is in proximity of the knee center. Crucial factors for the evaluation of axis deviation are the weight-bearing line, the mechanical axes of femur and tibia, the joint line angles and the center of the hip, knee and upper ankle joint. Careful preoperative planning is mandatory for reproducible clinical results...

Although ankle arthrodesis is the reference standard for end-stage ankle arthritis, loss of mobility and adjacent joint arthritis are consequences that alternatives to arthrodesis attempt to avoid. The purpose of the present study was to report the clinical results of interpositional arthroplasty using acellular dermal matrix in 4 patients (age 32 to 42 years) for the treatment of advanced ankle osteoarthritis. The primary findings included relief of pain, with improvement in tibiotalar joint range of motion from a mean of 16...

INTRODUCTION: Subtalar dislocation is an uncommon lesion in traumatology chiefly when it concerns the lateral form. Surgical treatment is required when a fracture is related or the dislocation is irreducible. Even well treated, these dislocations progress unavoidably to subtalar arthrosis, which stays well tolerated. CASE REPORT: A 46-year-old male with irreducible lateral subtalar dislocation caused sustentaculum tali incarceration confirmed on computed tomography (CT)...

The two-portal hindfoot arthroscopy is an effective procedure enabling direct visualisation of posterior ankle pathology with low invasiveness.An important stage of the hindfoot endoscopy is localisation of the flexor hallucis longus (FHL) tendon to protect the neurovascular bundle which is located just medial to it.Posterior ankle impingement syndrome and FHL tenosynovitis are common causes of posterior ankle pain and frequently occur together.Posteriorly localised talar osteochondral lesions, Achilles tendon disorders, osteoarthritis, talar bone cysts and talar fractures are among the other pathologies that can be treated with hindfoot arthroscopy...

Late stage ankle osteoarthritis often presents with debilitating pain. It is common to find osteophytes and loose body formation around the joint. Total ankle arthroplasty can preserve joint mobility and pain relieve for such patient. However, when trying to remove the osteophytes and loose bodies at the posterior ankle joint, there is risk of damaging posterior structures such as the neurovascular bundle during the procedure. We are presenting a case where the posterior loose bodies remained untouched during the operation, and patient showed spontaneous resolution of the lesions with time...

The majority of cases of upper ankle joint (UAJ) osteoarthritis are due to secondary causes. Clinically, osteoarthritis is usually characterized by an increasing limitation in dorsal extension of the UAJ with often relatively mild symptoms. In the course of time the full scale of the typical symptoms and the progressive restriction of the global function of the joint develop. Conservative therapy is often able to provide long-term improvement of the symptoms for the majority of patients by means of intermittent analgesics and orthoses as well as shoe modifications...

REVIEW
Lawrence A DiDomenico, Danielle N Butto
Subtalar joint arthrodesis is a procedure used in posttraumatic arthritis, osteoarthritis, tarsal coalition management, posterior tibial tendon dysfunction, and inflammatory arthropathies, and can be used in deformity correction. The goals of the procedure are to eliminate pain, improve function, restore stability, and realign the hind foot. The procedure has high patient satisfaction with low complications while preserving motion in adjacent tarsal joints. Joint preparation is important and time should be spent preparing the joint for successful arthrodesis and the fixation construct needs to be done well and effectively to provide a solid Arbeitsgemeinschaft für Osteosynthesefragen (AO) construct for good results...

AIMS: Tibiofemoral alignment is important to determine the rate of progression of osteoarthritis and implant survival after total knee arthroplasty (TKA). Normally, surgeons aim for neutral tibiofemoral alignment following TKA, but this has been questioned in recent years. The aim of this study was to evaluate whether varus or valgus alignment indeed leads to increased medial or lateral tibiofemoral forces during static and dynamic weight-bearing activities. PATIENTS AND METHODS: Tibiofemoral contact forces and moments were measured in nine patients with instrumented knee implants...

We treated a 57-year-old female with modified Takakura stage 3B varus ankle osteoarthritis. Her preoperative talar tilt angle was 21.3°. The patient wished to avoid ankle joint arthrodesis or replacement. Therefore, medial opening wedge supramalleolar osteotomy with fibular osteotomy was used for her varus ankle osteoarthritis. Also, fixed medial distraction arthroplasty was performed to improve her talar tilt. After 3 months, the external device was removed, and the patient was allowed partial weightbearing and began full weightbearing 4 months postoperatively after the osteotomy site had reached bony union radiographically...

Tibiotalar arthrodesis (TTA) is the gold-standard treatment for advanced ankle osteoarthritis. We describe an original fibular shortening osteotomy (FSO) performed during TTA, to allow complete talar ascension and reduce the non-union rate. Forty-two FSOs were associated to TTA (19 fixed by cross-screwing and 23 by anatomic plates), and assessed clinically and radiographically. At 24.7 months' follow-up, fusion rates were 97.6% for TTA and 100% for FSO, with mean fusion time of 5.2 months. One infection and 1 non-union (4...

Osteochondral allografts are used to treat many different conditions as acute traumatic large-sized lesions, degenerative osteoarthritis, osteochondritis dissecans, avascular necrosis or in case of failure of previous procedures particularly in young patients for whom primary prosthesis is not desirable. Fresh allografts present the advantage of having mature viable hyaline cartilage, not causing donor morbidity, allowing the restoration of even large defects in a single surgical session. Conversely, they could account for risks of disease transmission, immunologic reactions, and for limited availability...

REVIEW
Robin Queen
Ankle osteoarthritis is a debilitating disease with approximately 50,000 new cases per year leading to skeletal deformity, severe and recurrent pain, cartilage breakdown, and gait dysfunction limiting patient mobility and well-being. Although many treatments (total ankle arthroplasty [TAA], ankle fusion [arthrodesis], and ankle distraction arthroplasty) relieve pain, it is not clear that these procedures significantly improve patient mobility. The goal of the research presented here is to summarize what is presently known about lower extremity gait mechanics and outcomes and to quantify the impact of ankle osteoarthritis and TAA have on these measures using an explicitly holistic and mechanistic approach...

BACKGROUND: Osteotomy is a rational approach to slowing knee osteoarthritis progression by modifying loads, thereby avoiding joint replacement in younger individuals. Varus femoral osteotomy is recommended only in patients with more than 10° of valgus. The objective here was to assess outcomes of tibialvarus osteotomy in patients with lateral compartment tibio-femoral osteoarthritis and less than 10° of valgus. MATERIAL AND METHODS: A single-centre retrospective study was conducted in 19 consecutive patients managed by high tibialvarus osteotomy between January 2005 and May 2012...
