Matthias Aurich
This is the case of an 84-year-old patient 18 years after total knee replacement. Regular follow-up examinations did not take place beyond 10 years of implantation, so that subsequent wear of the polyethylene insert was not detected. The patient presented because of knee pain, swelling of the calf, and a drop foot. Examination showed a large ganglion with pressure on the peroneal nerve, and a loose knee replacement with severe inlay wear and extensive osteolysis around the tibial and femoral implants. This rare case demonstrates the importance of regular clinical and radiological follow-up examinations after total joint replacements, particularly in the long term...

OBJECTIVE: Whilst a number of risk factors for poor patient reported outcomes (PROMs) following knee arthroplasty (KA) have been identified, unexplained variability still remains. The role of pre-operative foot and ankle status on such outcomes has not been investigated. The aim of this study was therefore to determine the association of clinical foot and ankle assessments with patient reported outcomes one year following KA. DESIGN: One hundred and fifteen participants from the Clinical Outcomes in Arthroplasty Study (COASt), underwent detailed foot and ankle assessments at baseline, prior to KA (2012-2014) and were followed up for self-reported outcomes one year after surgery...

Dislocation following primary and revision arthroplasty is a well-recognised complication with an estimated incidence rate of 0.2-10%. We present a rare case of simultaneous bilateral total hip replacement dislocation, complicated by unilateral foot drop following closed reduction, with no improvement in neurological function at 6-month follow-up.

PURPOSE: We sought to determine and quantify which subspecialties of orthopedic surgeons are operating off hours in an urban, quaternary-care, level 1 trauma center. MATERIALS AND METHODS: We used our clinical registry to identify 43,211 orthopedic surgeries performed between January 2008 and December 2011. Our outcome measures were the number and proportion of off-hour surgeries performed as well as the number and proportion of off-hours per subspecialty. The denominators were the total number of surgeries and the total number of surgical hours worked per subspecialty...

BACKGROUND: In recent years, the number of total ankle arthroplasty procedures performed has increased dramatically. We sought to report the clinical results of the largest cohort of patients treated with a modern fixed-bearing total ankle arthroplasty by a single surgeon. METHODS: We retrospectively reviewed the charts of 78 consecutive patients (81 ankles) who underwent total ankle arthroplasty with a minimum clinical follow-up of 2 years. Sixty-three patients completed standardized questionnaires including the Foot and Ankle Disability Index (FADI), the Short Musculoskeletal Function Assessment (SMFA), the Short Form (SF)-36v2, and a visual analog scale (VAS) for pain...

Neurofibromatosis type-1 (NF1) is a multisystem disorder with very rare descriptions of hip instability. We report a case of a 37-year-old man with known NF1 and childhood-onset of left foot drop, who developed persistent left hip pain following a minor trauma. Physical examination revealed left-sided mild foot drop, hip abductor weakness, bilateral sensory loss in feet and an antalgic gait. Work-up revealed anterolateral subluxation of the left femoral head along with left hip plexiform neurofibroma (PN), dysplastic and degenerative changes, neurofibromatous neuropathy and chronic left L5 radiculopathy...

STUDY OBJECTIVE: Sciatic nerve block (SNB) is commonly used as adjunct to femoralis nerve block (FNB) to achieve high-quality pain relief after total knee arthroplasty (TKA). However, this combination is associated with considerable muscle weakness, foot drop and surgically related nerve injuries may be masked. The purpose of this study was to assess whether low risk continuous intra-articular anesthetic drug instillation is an adequate alternative to SNB when adding to FNB after TKA...

BACKGROUND: Arthroplasty of the first metatarsophalangeal joint is an alternative treatment option for end-stage hallux rigidus to the current gold standard of arthrodesis. The aim of this study was to investigate the mid-term functional outcome of an anatomically shaped prosthesis for the first metatarsophalangeal joint using pedobarography. METHODS: Ten patients (12 affected feet; age at surgery: 62.1 (SD: 7.2) years) were investigated preoperatively and 52 (SD: 3) months postoperatively using pedobarography (EMED, novel GmbH, Munich, Germany)...

PURPOSE: Although there have been many publications regarding the risk factors for implant-associated orthopaedic infections, none have investigated how clinical presentations and epidemiology may differ between infections with and without osteosynthetic material. METHODS: We pooled clinical data from several databases of adult patients with orthopaedic infections hospitalized at Geneva University Hospitals from January 2004 to December 2014. RESULTS: Among 2740 episodes of orthopaedic infections, 76% were implant-free osteoarticular or soft tissue infections...

This case report describes a successful two-stage treatment in a 75-year-old male with a displaced neck of femur fracture, also suffering from an active chronic osteomyelitis of the ipsilateral calcaneus. In our case, a below-knee amputation was performed first, followed by total hip arthroplasty two weeks later. At 15-month follow-up, full recovery of the prefracture level of activities of daily living without significant impairment was obtained. Only a few cases of total hip arthroplasty in amputees have been published, but the indication for surgery was mainly traumatic or advanced osteoarthritis...

PURPOSE: Total ankle arthroplasty (TAA) and ankle arthrodesis (AA) are the main surgical treatment options for end-stage ankle arthritis. Although the superiority of each modality remains debated, there remains a lack of high-quality evidence-based studies, such as randomized controlled clinical trials, and meta-analyses of comparative studies. We performed a meta-analysis of comparative studies to determine whether there is a significant difference between these two procedures in terms of (i) clinical scores and patient satisfaction, (ii) re-operations, and (iii) complications...

BACKGROUND: Functional recovery following total ankle arthroplasty (TAA) is assessed with patient-reported metrics, but physical performance tests may allow for a more accurate assessment of patient function. We quantified correlations between patient-reported measures and physical performance tests in patients after TAA to determine the usefulness of physical performance tests in post-TAA assessment. METHODS: In total, 140 patients with end-stage ankle osteoarthritis were assessed prior to TAA and again at 12 and 24 months postoperatively...

: First metatarsophalangeal joint arthritis can stem from a biomechanical imbalance as in hallux abducto valgus, metabolic arthritidies such as rheumatoid or gout, and even in posttraumatic cases. Advanced arthritis in the foot and ankle can often become debilitating. Surgical intervention is often necessary. Revision of failed first metatarsophalangeal joint arthroplasty is often in the setting of bony erosion and lysis, cystic changes, and loss of bone stock. In this article, we describe first metatarsophalangeal distraction arthrodesis technique using tricortical calcaneus autograft with the aim of simplifying donor site graft harvesting and decreasing donor site morbidity while attaining successful osseous union...

The aim of the study was to assess lower limb loading during walking after unilateral total hip arthroplasty (THA) revision. Twenty-three THA revision subjects (12 men, 11 women) were divided into three groups according to time since surgery as 1 to 6 years, 6 to 11 years, and over 11 years. Two force plates were used to measure the ground reaction force during the stance phase. On the operated limb, compared to nonoperated limb, we found lower first vertical peak in the group of 1 to 6 years after revision and lower propulsion peak in the group of 6 to 11 years since revision...
