Preoperative talar valgus deformity ≥ 15° is considered a contraindication for total ankle arthroplasty (TAA). We compared operative procedures and clinical outcomes of TAA in patients with talar valgus deformity ≥ 15° and < 15°. A matched cohort of patients similar for demographics and components used but differing in preoperative coronal-plane tibiotalar valgus deformity ≥ 15° (valgus, n = 50; 52% male, mean age 65.8 years (SD 10.3), mean body mass index (BMI) 29.4 (SD 5.2)) or < 15° (control, n = 50; 58% male, mean age 65.6 years (SD 9.8), mean BMI 28.7 (SD 4.2)), underwent TAA by one surgeon. Preoperative and postoperative radiographs, Ankle Osteoarthritis Scale (AOS) pain and disability and 36-item Short Form Health Survey (SF-36) version 2 scores were collected prospectively. Ancillary procedures, secondary procedures, and complications were recorded.Aims
Methods
Most patients (95%) with fibular hemimelia have
an absent anterior cruciate ligament (ACL). The purpose of this study
was to assess the long-term outcome of such patients with respect
to pain and knee function. We performed a retrospective review of
patients with fibular hemimelia and associated ACL deficiency previously
treated at our institution. Of a possible 66 patients, 23 were sent
the Musculoskeletal Outcomes Data Evaluation and Management System
(MODEMS) questionnaire and Lysholm knee score to complete. In all,
11 patients completed the MODEMS and nine completed the Lysholm
score questionnaire. Their mean age was 37 years (27 to 57) at review.
Five patients had undergone an ipsilateral Symes amputation. There
was no significant difference in any subsections of the Short-Form
36 scores of our patients compared with age-matched controls. The
mean Lysholm knee score was 90.2 (82 to 100). A slight limp was
reported in six patients. No patients had episodes of locking of the
knee or required a supportive device for walking. Four had occasional
instability with sporting activities. These results suggest that patients with fibular hemimelia and
ACL deficiency can live active lives with a similar health status
to age-matched controls.
We report a case which highlights the progression of osteofibrous dysplasia to adamantinoma and questions whether intralesional curettage is the appropriate treatment. The role of a joint-sparing massive endoprosthesis using cortical fixation is demonstrated and we describe a unique biomedical design which resulted in the manufacture of an end cap to allow amputation through a custom-made proximal tibial replacement, rather than an above-knee amputation following recurrence.
Tibial dysplasia is a rare congenital deformity which must be distinguished from the more common
