Little is known about the relative outcomes of revision of unicompartmental
knee arthroplasty (UKA) and high tibial osteotomy (HTO) to total
knee arthroplasty (TKA). The aim of this study is to compare the
outcomes of revision surgery for the two procedures in terms of
complications, re-revision and patient-reported outcome measures (PROMs)
at a minimum of two years follow-up. This study was a retrospective review of data from an institutional
arthroplasty registry for cases performed between 2001 and 2014.
A total of 292 patients were identified, of which 217 had a revision
of HTO to TKA, and 75 had revision of UKA to TKA. While mean follow-up
was longer for the HTO group compared with the UKA group, patient
demographics (age, body mass index and Charlson co-morbidity index)
and PROMs (Short Form-36, Oxford Knee Score, Knee Society Score,
both objective and functional) were similar in the two groups prior
to revision surgery. Outcomes included the rate of complications
and
re-operation, PROMS and patient-reported satisfaction at six months
and two years post-operatively. We also compared the duration of
surgery and the need for revision implants in the two groups. Aims

Our goal was to evaluate the use of Ponseti’s
method, with minor adaptations, in the treatment of idiopathic clubfeet
presenting in children between five and ten years of age. A retrospective
review was performed in 36 children (55 feet) with a mean age of
7.4 years (5 to 10), supplemented by digital images and video recordings
of gait. There were 19 males and 17 females. The mean follow-up
was 31.5 months (24 to 40). The mean number of casts was 9.5 (6
to 11), and all children required surgery, including a percutaneous
tenotomy or open tendo Achillis lengthening (49%), posterior release
(34.5%), posterior medial soft-tissue release (14.5%), or soft-tissue
release combined with an osteotomy (2%). The mean dorsiflexion of
the ankle was 9° (0° to 15°). Forefoot alignment was neutral in
28 feet (51%) or adducted (<
10°) in 20 feet (36%), >
10° in
seven feet (13%). Hindfoot alignment was neutral or mild valgus
in 26 feet (47%), mild varus (<
10°) in 19 feet (35%), and varus
(>
10°) in ten feet (18%). Heel–toe gait was present in 38 feet
(86%), and 12 (28%) exhibited weight-bearing on the lateral border
(out of a total of 44 feet with gait videos available for analysis).
Overt relapse was identified in nine feet (16%, six children). The
parents of 27 children (75%) were completely satisfied. A plantigrade foot was achieved in 46 feet (84%) without an extensive
soft-tissue release or bony procedure, although under-correction
was common, and longer-term follow-up will be required to assess
the outcome. Cite this article:
The April 2013 Children’s orthopaedics Roundup360 looks at: improving stress distribution in dysplastic hips; the dangers of fashion; the natural history of supracondylar fractures; ankles that perform well as knees; intra-articular hip pathology at osteotomy; the safe removal of flexible nails; supracondylar fracture fixation; and talipes.
Revision total hip arthroplasty (THA) is challenging
when there is severe loss of bone in the proximal femur. The purpose
of this study was to evaluate the clinical and radiographic outcomes
of revision THA in patients with severe proximal femoral bone loss
treated with a fluted, tapered, modular femoral component. Between
January 1998 and December 2004, 92 revision THAs were performed
in 92 patients using a single fluted, tapered, modular femoral stem
design. Pre-operative diagnoses included aseptic loosening, infection
and peri-prosthetic fracture. Bone loss was categorised pre-operatively
as Paprosky types III-IV, or Vancouver B3 in patients with a peri-prosthetic
fracture. The mean clinical follow-up was 6.4 years (2 to 12). A
total of 47 patients had peri-operative complications, 27 of whom
required further surgery. However, most of these further operations
involved retention of a well-fixed femoral stem, and 88/92 femoral
components (97%) remained Revision THA in patients with extensive proximal femoral bone
loss using the Link MP fluted, tapered, modular stem led to a high
rate of osseointegration of the stem at mid-term follow-up. Cite this article:
We report a new surgical technique of open carpal
tunnel release with subneural reconstruction of the transverse carpal
ligament and compare this with isolated open and endoscopic carpal
tunnel release. Between December 2007 and October 2011, 213 patients with carpal
tunnel syndrome (70 male, 143 female; mean age 45.6 years; 29 to
67) were recruited from three different centres and were randomly
allocated to three groups: group A, open carpal tunnel release with
subneural reconstruction of the transverse carpal ligament (n =
68); group B, isolated open carpal tunnel release (n = 92); and
group C, endoscopic carpal tunnel release (n = 53). At a mean final follow-up of 24 months (22 to 26), we found no
significant difference between the groups in terms of severity of
symptoms or lateral grip strength. Compared with groups B and C,
group A had significantly better functional status, cylindrical
grip strength and pinch grip strength. There were significant differences
in Michigan Hand Outcome scores between groups A and B, A and C,
and B and C. Group A had the best functional status, cylindrical
grip strength, pinch grip strength and Michigan Hand Outcome score. Subneural reconstruction of the transverse carpal ligament during
carpal tunnel decompression maximises hand strength by stabilising
the transverse carpal arch. Cite this article:
