Robotic-Assisted versus Manual Unicompartmental Knee Arthroplasty: Contemporary Systematic Review and Meta-analysis of Early Functional Outcomes

J Knee Surg DOI: 10.1055/s-0040-1701455Robotic-assisted unicompartmental knee arthroplasty (RA-UKA) aims to improve accuracy of component placement. Studies have shown improvement in radiographic positioning/alignment with RA-UKA but have not addressed clinical outcome measures (COMs). The purpose of this study was to determine if RA-UKA is associated with improved early revision rates and functional outcome scores (FOS) compared with manual UKA. A systematic review of all English language articles from 1999 to 2019 on RA-UKA using Medline, EMBASE, Scopus, and Web of Science databases identified 277 studies. Seven (three randomized controlled trials) met inclusion criteria. Revision rates/FOS were aggregated for RA-UKA and manual UKA; a forest plot was constructed utilizing inverse variance/Mantel–Haenszel fixed-effects meta-analysis. The seven articles included a total of 363 RA-UKA patients and 425 manual UKA patients. Mean age was 66 ± 3.5 and 65 ± 4.0 years, and mean body mass index (BMI) was 26.8 ± 2.1 and 27.1 ± 1.5 kg/m2, respectively. Mean follow-up was 25.5 months (4.5–48) and 29.1 months (4.5–48) for RA-UKA and manual UKA, respectively. At latest follow-up, RA-UKA patients showed a 26% ± 12 improvement in COMs versus 24% ± 12 improvement for manual UKA patients (p = 0.6). The revision rate was 3% for bot...

Conclusions: Our results confirmed the perpendicularity of the interlaminar line with the pedicle axis in the lumbar spine at all the levels. The interlaminar line is a useful guide for pedicle screw sagittal inclination. PMID: 32050312 [PubMed - as supplied by publisher]

ConclusionsOsteochondral lesions of the lateral trochlear ridge are rare but important, as these patients go on to arthroscopy at a high rate. If an abnormality of the lateral trochlear ridge is seen or suspected, we recommend CT as the best imaging study to define these lesions.

This report describes a 69-year-old female patient who presented with right hip pain and was later found to have an osseous mass-like lesion in the right proximal femur, with radiographic findings resembling those of a benign bone tumor. CT-guided biopsy and surgical biopsy showed that the mass had pathologic findings typical of bone oxalosis. Because the patient had no predisposing factors for systemic oxalosis and had no hyperoxalemia or hyperoxaluria, she could be diagnosed with localized bone oxalate deposition disease or bone oxaloma rather than bone oxalosis. This is the first report of this clinical entity to presen...

ConclusionsThis study demonstrates a proof of principle that deep learning can be applied to assess knee pain from MRI scans.Key Points• Our article is the first to leverage a deep learning framework to associate MR images of the knee with knee pain.• We developed a convolutional Siamese network that had the ability to fuse information from multiple two-dimensional (2D) MRI slices from the knee with pain and the contralateral knee of the same individual without pain to predict unilateral knee pain.• Our model achieved an area under curve (AUC) value of 0.808. When individuals who had WOMAC pain scores that w...

We describe a case of a staphylococcal lung abscess in a teenage girl with CF who presented with a two-week history of non-specific malaise followed by two days of left posterior chest pain and fever. A chest radiograph was consistent with a left sided pulmonary abscess, which was confirmed on a CT scan of the chest. The abscess was drained under ultrasound guidance and cultured methicillin-sensitive Staphylococcus aureus. The patient responded well to antibiotic treatment with the abscess cavity showing complete radiological resolution by six weeks post drainage.

This study therefore describes sick leave in men with distal radius fracture, specifically exploring the impact of patient- and fracture-related factors.Methods Professionally active men aged 20 –65 with distal radius fracture were followed prospectively for 1-year (n = 88). Data included treatment method, radiographic parameters pre/post treatment, complications, health, lifestyle and occupational demand. Patient outcomes were self-reported sick leave; Disability of the Arm, Shoulder and Hand (DASH) score; pain (5 likert scale); SF-36: Physical Component Scale (PCS) and Mental Component Scale (MCS).Res...

This study aimed to determine the incidence of PAPS after primary TKA, identify potential risk factors, and assess its response to treatment. Few case reports have been published until now; to our knowledge, ours is the first study assessing the incidence and predictors of post-TKA PAPS.MethodsA total of 389 primary TKAs performed for degenerative varus knee at a single institution by the same surgeon were analyzed. We recorded demographic variables, medical comorbidities, and clinical, radiographic, and surgical data. Specific predictors of interest were compared between post-TKA PAPS and controls.ResultsThe incidence was...
