Objectives. This study reports on a secondary exploratory analysis of the early clinical outcomes of a randomised clinical trial comparing robotic arm-assisted unicompartmental knee arthroplasty (UKA) for medial compartment osteoarthritis of the knee with manual UKA performed using traditional surgical jigs. This follows reporting of the primary outcomes of implant accuracy and gait analysis that showed significant advantages in the robotic arm-assisted group. Methods. A total of 139 patients were recruited from a single centre. Patients were randomised to receive either a manual UKA implanted with the aid of traditional surgical jigs, or a UKA implanted with the aid of a tactile guided robotic arm-assisted system. Outcome measures included the American Knee Society Score (AKSS), Oxford Knee Score (OKS), Forgotten Joint Score, Hospital Anxiety Depression Scale, University of California at Los Angeles (UCLA) activity scale, Short Form-12, Pain Catastrophising Scale, somatic disease (Primary Care Evaluation of Mental Disorders Score), Pain visual analogue scale, analgesic use, patient satisfaction, complications relating to surgery, 90-day pain diaries and the requirement for revision surgery. Results. From the first post-operative day through to week 8 post-operatively, the median pain scores for the robotic arm-assisted group were 55.4% lower than those observed in the manual surgery group (p = 0.040). At three months post-operatively, the robotic arm-assisted group had better AKSS (robotic median 164, interquartile range (IQR) 131 to 178, manual median 143, IQR 132 to 166), although no difference was noted with the OKS. At one year post-operatively, the observed differences with the AKSS had narrowed from a median of 21 points to a median of seven points (p = 0.106) (robotic median 171, IQR 153 to 179; manual median 164, IQR 144 to 182). No difference was observed with the OKS, and almost half of each group reached the ceiling limit of the score (OKS > 43). A greater proportion of patients receiving robotic arm-assisted surgery improved their UCLA activity score. Binary logistic regression modelling for dichotomised outcome scores predicted the key factors associated with achieving excellent outcome on the AKSS: a pre-operative activity level > 5 on the UCLA activity score and use of robotic-arm surgery. For the same regression modelling, factors associated with a poor outcome were manual surgery and pre-operative depression. Conclusion. Robotic arm-assisted surgery results in improved early pain scores and early function scores in some
Objectives. Electronic forms of data collection have gained interest in recent
years. In orthopaedics, little is known about patient preference
regarding pen-and-paper or electronic questionnaires. We aimed to
determine whether patients undergoing total hip (THR) or total knee
replacement (TKR) prefer pen-and-paper or electronic questionnaires
and to identify variables that predict preference for electronic
questionnaires. Methods. We asked patients who participated in a multi-centre cohort study
investigating improvement in health-related quality of life (HRQoL)
after THR and TKR using pen-and-paper questionnaires, which mode
of questionnaire they preferred. Patient age, gender, highest completed
level of schooling, body mass index (BMI), comorbidities, indication
for joint replacement and pre-operative HRQoL were compared between
the groups preferring different modes of questionnaire. We then
performed logistic regression analyses to investigate which variables
independently predicted preference of electronic questionnaires. Results. A total of 565 THR patients and 387 TKR patients completed the
preference question. Of the THR patients, 81.8% (95% confidence
interval (CI) 78.4 to 84.7) preferred pen-and-paper questionnaires
to electronic questionnaires, as did 86.8% (95% CI 83.1 to 89.8)
of TKR patients. Younger age, male gender, higher completed level
of schooling and higher BMI independently predicted preference of
electronic questionnaires in THR patients. Younger age and higher
completed level of schooling independently predicted preference
of electronic questionnaires in TKR patients. Conclusions. The majority of THR and TKR patients prefer pen-and-paper questionnaires.
Patients who preferred electronic questionnaires differed from patients
who preferred pen-and-paper questionnaires. Restricting the mode

Participants walked on a treadmill with the KneeKG system at a slow imposed speed (2 km/hr) for three trials, then at a self-selected comfortable walking speed for another three trials.

To define Patient Acceptable Symptom State (PASS) thresholds
for the Oxford hip score (OHS) and Oxford knee score (OKS) at mid-term
follow-up. In a prospective multicentre cohort study, OHS and OKS were collected
at a mean follow-up of three years (1.5 to 6.0), combined with a
numeric rating scale (NRS) for satisfaction and an external validation
question assessing the patient’s willingness to undergo surgery
again. A total of 550 patients underwent total hip replacement (THR)
and 367 underwent total knee replacement (TKR).Objectives
Methods
This protocol describes a pragmatic multicentre
randomised controlled trial (RCT) to assess the clinical and cost
effectiveness of arthroscopic and open surgery in the management
of rotator cuff tears. This trial began in 2007 and was modified
in 2010, with the removal of a non-operative arm due to high rates
of early crossover to surgery. Cite this article:

within the orthopaedic literature. A protocol was established and studies were sourced from five
electronic databases. Screening, data abstraction and quality assessment
was conducted by two review authors. Prospective and retrospective
clinical studies were included. The primary outcome measures were
based on clinical and/or radiological indicators of bone healing.
