Suction drainage in total knee replacement does not influence early functional outcomes or blood loss: a randomized control trial.

INTRODUCTION: The use of wound drainage following total knee arthroplasty (TKA) remains controversial. The purpose of this study was to evaluate the impact of suction drainage on early postoperative outcomes in patients who underwent TKA with concomitant administration of intravenous tranexamic acid (TXA). METHOD: One hundred forty-six patients undergoing primary TKA with systematic intravenous TXA were prospectively selected and randomly divided into two groups. The first "Study group" (n = 67) received no suction drain and the second "Control" group (n = 79) had a suction drain. Perioperative hemoglobin levels, blood loss, complications, and length of hospital stay were assessed in both groups. Preoperative and postoperative range of motion and Knee Injury and Osteoarthritis Outcome Scores (KOOS) were also compared at a 6-week follow-up. RESULTS: The study group was found to have higher hemoglobin levels preoperatively and during the first two days following surgery, and no difference was found between the groups on the third day. No significant discrepancies at any time were found between groups in terms of blood loss, length of hospitalization, knee range of motion, and KOOS score. Complications requiring further treatment were observed in one patient from the study group and ten patients from the control group. CONCLUSION: The use of suction drains after TKA with TXA did not alter early postoperative outcomes.

Bicruciate-retaining total knee arthroplasty non-inferior to posterior-stabilized prostheses after 5 years: a randomized, controlled trial.

PURPOSE: Bicruciate-retaining (BCR) prostheses may improve satisfaction of patient undergoing total knee arthroplasty (TKA). The objective of this randomized controlled trial was to assess whether BCR prostheses provide better clinical outcomes than posterior-stabilized (PS) prostheses. MATERIALS AND METHODS: This is a randomized single-blind control trial involving a total of 77 patients with knee osteoarthritis, randomly assigned to undergo TKA with a BCR or PS implant between 2015 and 2019. Mean follow-up period was 39 months. Clinical and demographic data were extracted manually from medical records. Data acquisition included patient demographics, knee range of motion, and patient-reported outcomes via KSS, KOOS, WOMAC, and SF-12 scores. RESULTS: A total of 38 patients were randomized to the PS group and 39 to the BCR group. At the 5-year follow-up, no statistical differences were noted for knee range of motion or patient-reported outcomes between the two groups, except for a greater knee flexion in the early follow-up period in the PS group. Five adverse events occurred in the BCR group compared to none in the PS group (p = 0.02). CONCLUSION: BCR TKA yield similar clinical and patient-reported outcomes 5 years following the intervention compared with PS TKA. The BCR TKA had more complications. LEVEL OF EVIDENCE: I (Randomized Controlled Trial).

Talectomy for arthrogrypotic foot deformities: A systematic review.

BACKGROUND: Arthrogryposis multiplex congenita (AMC) is one of the most common congenital joint contracture syndromes. Talectomy has been proposed for severe foot deformities in AMC, but the literature is limited. The purpose of this systematic review is to evaluate the indications, outcomes and complications of talectomy in arthrogrypotic foot deformities. METHODS: The articles were found through Embase and Medline. Screening was conducted by two independent investigators with disagreements resolved by a third reviewer. Relevant data regarding demographics, outcomes and complications were collected. RESULTS: Of 232 feet, 71.98 % and 62.22 % had clinical and radiographic improvements respectively. Amongst 122 patients, 92.62 % could ambulate following surgery. Recurrent deformities and revision surgery were seen in 16.81 % and 13.36 % of cases respectively. CONCLUSIONS: Talectomy is a valid surgical option for severe arthrogrypotic foot deformities with favorable post-operative outcomes and low complication rate.

Variable expressivity in a family with an aggrecanopathy.

BACKGROUND: Osteochondritis dissecans is a condition wherein there is a subchondral bone lesion that causes pain, inflammation, and cartilage damage. Dominant Familial Osteochondritis Dissecans is a rare and severe form of osteochondritis dissecans (OCD). It is caused by heterozygous pathogenic variants in the gene encoding Aggrecan; ACAN. Aggrecan, a proteoglycan, is an essential component of the articular and growth plate cartilage. METHODS: Herein, we report three individuals from one family; the proband who presented with short stature, a lower limb bone exostosis, and bilateral knee and elbow OCD at the age of 13 years old. His twin brother presented with isolated short stature and his father with short stature and lumbar disc herniation. RESULTS: Next-generation sequencing of the ACAN gene in the proband identified a frameshift variant which is also present in the brother and father with short stature. The proband was treated surgically with bilateral elbow microfracture, after the failure of conservative therapy. CONCLUSION: To the best of our knowledge, this is the first patient with an aggrecanopathy who presents with osteochondritis dissecans due to a frameshift variant. This family presents with variable expressivity which might be attributed to modifier genes.

A Case of Torsion of the Gallbladder Suspected with SPECT-CT: Review and Recommendations.

Torsion or volvulus of the gallbladder is a rare situation that rapidly progresses to gangrene and linked with a poor prognosis, even death, if unrecognized and untreated. An interesting and rare case of gallbladder volvulus in which diagnosis was obtained by comparing CT images and HIDA scan with SPECT-CT is presented. Relevant literature is reviewed, and recommendations are outlined.
