The purpose of this study was to evaluate the
effect of various non-operative modalities of treatment (transcutaneous
electrical nerve stimulation (TENS); neuromuscular electrical stimulation
(NMES); insoles and bracing) on the pain of osteoarthritis (OA)
of the knee. We conducted a systematic review according to the Preferred Reporting
Items for Systematic Reviews and Meta-Analyses guidelines to identify
the therapeutic options which are commonly adopted for the management
of osteoarthritis (OA) of the knee. The outcome measurement tools used in the different studies were
the visual analogue scale and The Western Ontario and McMaster Universities
Arthritis Index pain index: all pain scores were converted to a
100-point scale. A total of 30 studies met our inclusion criteria: 13 on insoles,
seven on TENS, six on NMES, and four on bracing. The standardised
mean difference (SMD) in pain after treatment with TENS was 1.796,
which represented a significant reduction in pain. The significant
overall effect estimate for NMES on pain was similar to that of
TENS, with a SMD of 1.924. The overall effect estimate of insoles
on pain was a SMD of 0.992. The overall effect of bracing showed
a significant reduction in pain of 1.34. Overall, all four non-operative modalities of treatment were
found to have a significant effect on the reduction of pain in OA
of the knee. This study shows that non-operative physical modalities of treatment
are of benefit when treating OA of the knee. However, much of the
literature reviewed evaluates studies with follow-up of less than
six months: future work should aim to evaluate patients with longer
follow-up. Cite this article:
External fixation is widely used in orthopaedic
and trauma surgery. Infections around pin or wire sites, which are usually
localised, non-invasive, and are easily managed, are common. Occasionally,
more serious invasive complications such as necrotising fasciitis
(NF) and toxic shock syndrome (TSS) may occur. We retrospectively reviewed all patients who underwent external
fixation between 1997 and 2012 in our limb lengthening and reconstruction
programme. A total of eight patients (seven female and one male)
with a mean age of 20 years (5 to 45) in which pin/wire track infections
became limb- or life-threatening were identified. Of these, four
were due to TSS and four to NF. Their management is described. A
satisfactory outcome was obtained with early diagnosis and aggressive
medical and surgical treatment. Clinicians caring for patients who have external fixation and
in whom infection has developed should be aware of the possibility
of these more serious complications. Early diagnosis and aggressive
treatment are required in order to obtain a satisfactory outcome. Cite this article:
