Multiple secondary surgical procedures of the shoulder, such as soft-tissue releases, tendon transfers, and osteotomies, are described in brachial plexus birth palsy (BPBP) patients. The long-term functional outcomes of these procedures described in the literature are inconclusive. We aimed to analyze the literature looking for a consensus on treatment options. A systematic literature search in healthcare databases (PubMed, Embase, the Cochrane library, CINAHL, and Web of Science) was performed from January 2000 to July 2020, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. The quality of the included studies was assessed with the Cochrane ROBINS-I risk of bias tool. Relevant trials studying BPBP with at least five years of follow-up and describing functional outcome were included.Aims
Methods
We wished to compare the clinical outcome, as assessed by questionnaires
and the rate of complications, in total knee arthroplasty (TKA)
undertaken with patient-matched positioning guides (PMPGs) or conventional
instruments. A total of 180 patients (74 men, 106 women; mean age 67 years)
were included in a multicentre, adequately powered, double-blind,
randomised controlled trial. The mean follow-up was 44 months (24
to 57).Aims
Patients and Methods
This prospective randomised controlled trial was designed to
evaluate the outcome of both the MRI- and CT-based patient-specific
matched guides (PSG) from the same manufacturer. A total of 137 knees in 137 patients (50 men, 87 women) were
included, 67 in the MRI- and 70 in the CT-based PSG group. Their
mean age was 68.4 years (47.0 to 88.9). Outcome was expressed as
the biomechanical limb alignment (centre hip-knee-ankle: HKA-axis)
achieved post-operatively, the position of the individual components
within 3° of the pre-operatively planned alignment, correct planned
implant size and operative data (e.g. operating time and blood loss).Aims
Patients and Methods
Although it has been suggested that the outcome
after revision of a unicondylar knee replacement (UKR) to total knee
replacement (TKR) is better when the mechanism of failure is understood,
a comparative study on this subject has not been undertaken. A total of 30 patients (30 knees) who underwent revision of their
unsatisfactory UKR to TKR were included in the study: 15 patients
with unexplained pain comprised group A and 15 patients with a defined
cause for pain formed group B. The Oxford knee score (OKS), visual
analogue scale for pain (VAS) and patient satisfaction were assessed before
revision and at one year after revision, and compared between the
groups. The mean OKS improved from 19 (10 to 30) to 25 (11 to 41) in
group A and from 23 (11 to 45) to 38 (20 to 48) in group B. The
mean VAS improved from 7.7 (5 to 10) to 5.4 (1 to 8) in group A
and from 7.4 (2 to 9) to 1.7 (0 to 8) in group B. There was a statistically
significant difference between the mean improvements in each group
for both OKS (p = 0.022) and VAS (p = 0.002). Subgroup analysis
in group A, performed in order to define a patient factor that predicts
outcome of revision surgery in patients with unexplained pain, showed
no pre-operative differences between both subgroups. These results may be used to inform patients about what to expect
from revision surgery, highlighting that revision of UKR to TKR
for unexplained pain generally results in a less favourable outcome
than revision for a known cause of pain. Cite this article:
