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...

Background: Chronic Monteggia lesions in children may cause pain, deformity, decreased range of motion, and neurological symptoms. Numerous surgical techniques have been advocated to reconstruct long-standing Monteggia injures in efforts to maximize long-term upper limb function. The purpose of this investigation was to assess the clinical and radiographic results of a modified surgical technique for missed Monteggia fracture-dislocations. Methods: A retrospective evaluation of 52 patients who underwent surgical reconstruction of missed Monteggia fracture-dislocations at a tertiary pediatric hospital was performed. Th...

Radiographic parameters are commonly used to determine the need for surgical supracondylar humeral (SCH) fracture reduction and the postoperative quality of reduction. We studied whether such parameters are correlated with mid-term patient-reported outcome (PRO) scores in pediatric patients. We retrospectively reviewed data from 213 patients (104 girls) treated surgically for Gartland type-II (n = 84) or type-III (n = 129) SCH fractures from 2008–2016. Mean (± standard deviation) age at surgery was 5.1 ± 2.1 years. Mean time from initial treatment to outcome survey completion was 5.0 &plu...

The purpose of this retrospective study was to determine the most appropriate distal fusion level in terms of clinical results and radiological changes in Lenke 3C adolescent idiopathic scoliosis (AIS). Between June 2010 and May 2014, a total of 90 consecutive patients who underwent surgery for Lenke 3C AIS were divided into three groups as L2, L3, and L4 according to the fusion levels and compared in terms of functional and radiological outcomes. Patients were evaluated with Scoliosis Research Society 22 (SRS 22) and the Oswestry disability index (ODI) at the final follow-up. Preoperative standard posteroanterior and late...

“Misdiagnosed Lisfranc injuries can be as high as 50%, leading to chronic pain, functional impairment, and posttraumatic arthritis. Subtle or incomplete lesions are the most problematic group for an adequate diagnosis. Conventional non–weight-bearing radiographs can overlook up to 30% of unstabl e cases. Abduction stress radiographs and anteroposterior monopodial comparative weight-bearing radiographic views are very useful to identify instability. Computed tomography gives detailed information about fracture patterns and comminution. MRI can predict instability but it is expensive and not readily available in ...

In this study, a novel 3-dimensional (3D) printed integral customized acetabular prosthesis for anatomical rotation restoration in THA for DDH Crowe type III was developed using patient-specific Computer-aided design and additive manufacturing (AM) methods. Patient concerns: A 69-year-old female patient had developed left hip joint pain and restricted movement for 40 years; the symptoms had increased in the past 5 months. Pain, limited motion of the left hip joint, and lower limb length discrepancy were noted during physical examination. Diagnosis: The patient was diagnosed with left hip end-stage osteoarthritis seco...

Conclusions: Pedicle screws placed with 3DP drill guides may result in shorter operative time, less blood loss, and a greater probability of excellent screw placement as compared with those placed with freehand techniques. We conclude that 3DP guides may potentially develop into an efficient and accurate option for pedicle screw placement. However, more prospective, randomized controlled trials are needed to strengthen the confidence of these conclusions. Level of Evidence: Level III.

Temporomandibular joint (TMJ) involvement is often silent in juvenile idiopathic arthritis (JIA). Untreated, it can cause pain, growth disturbances, malocclusion, and skeletal deformities. Currently, combined clinical examination and radiographic imaging (i.e., magnetic resonance imaging, MRI) are necessary for diagnosis and treatment. However, imaging is not always feasible due to its high cost, access, occasional need for sedation and potential contraindications.1 Acoustic emissions (AEs) are the sounds produced from articulation in a joint.2 To measure the AEs of the TMJ, we built a custom headset with 2 uniaxial Dytran...
