The authors suggest that this relatively simple procedure can be of significant benefit to those athletes wishing to return to their previous levels of physical activity when more nonoperative measures have proven unsuccessful.
Background: Autograft choice in anterior cruciate ligament reconstruction (ACLR) remains controversial, with increasing interest in the usage of quadriceps tendon (QT) autograft versus traditional hamstring tendon (HT) use. The current study undertakes an in-depth review and comparison of the clinical and functional outcomes of QT and HT autografts in ACLR. Hypothesis: The QT autograft is equivalent to the HT autograft and there will be little or no significant difference in the outcomes between these 2 autografts. Study Design: Systematic review and meta-analysis; Level of evidence, 4. Methods: The PUBMED, EMBASE, MEDLINE, and CENTRAL databases were systematically searched from their inception until November 2020. All observational studies comparing ACLR QT and HT autografts were assessed for their methodological quality. Patient outcomes were compared according to patient-reported outcome measures (International Knee Documentation Committee [IKDC], Cincinnati, Lysholm, Tegner, and visual analog scale [VAS] measures), knee extensor and flexor torque limb symmetry indices (LSIs), hamstring to quadriceps (H/Q) ratios, functional hop capacity, knee laxity, ipsilateral graft failure, and contralateral injury. Results: A total of 20 observational studies comprising 28,621 patients (QT = 2550; HT = 26,071) were included in the quantitative meta-analysis. In comparison with patients who received an HT autograft, those who received a QT autograft had similar postoperative Lysholm (mean difference [MD], 0.67; P = .630), IKDC (MD, 0.48; P = .480), VAS pain (MD, 0.04; P = .710), and Cincinnati (MD, -0.85; P = .660) scores; LSI for knee flexor strength (MD, 6.06; P = .120); H/Q ratio (MD, 3.22; P = .160); hop test LSI (MD, -1.62; P = .230); pivot-shift test grade 0 (odds ratio [OR], 0.80; P = .180); Lachman test grade 0 (OR, 2.38; P = .320), side-to-side laxity (MD, 0.09; P = .650); incidence of graft failure (OR, 1.07; P = .830) or contralateral knee injury (OR, 1.22; P = .610); and Tegner scores (MD, 0.11; P = .060). HT autografts were associated with a higher (better) side-to-side LSI for knee extensor strength (MD, -6.31; P = .0002). Conclusion: In this meta-analysis, the use of the QT autograft was equivalent to the HT autograft in ACLR, with comparable graft failure and clinical and functional outcomes observed. However, HT autografts were associated with better LSI knee extensor strength.
The Dermabond Prineo skin closure system (Ethicon, Somerville, New Jersey) is a wound closure device that combines a 2-octyl cyanoacrylate liquid adhesive and a self-adhesive polyester mesh. Although cyanoacrylates traditionally have been associated with low rates of sensitization, allergic contact dermatitis (ACD) to Dermabond products is being increasingly reported after orthopedic surgery. The authors describe the first case series of ACD to Dermabond Prineo where patch testing confirmed the diagnosis in all patients. Six patients who had suspected Dermabond Prineo ACD after lower limb orthopedic surgery were assessed. Of these patients, 5 had itching within 4 days of surgery and rash within 5 days. All 5 of these patients reported previous exposure to Dermabond products. All patients had removal of the adhesive and mesh earlier than planned and were treated with corticosteroids. In addition, 4 patients received systemic antibiotics; however, only 1 had a microbiologically confirmed superficial skin infection. In all patients, the dermatitis resolved within 2 weeks of dressing removal, with no adverse effect on the orthopedic outcome. Patch testing showed positive reactions to Dermabond Prineo glue for all patients. Orthopedic surgeons should be aware of the potential for ACD to Dermabond Prineo, especially among patients with previous exposure to Dermabond products. The authors discuss the risk factors for ACD to Dermabond Prineo in the orthopedic cohort and provide recommendations for prevention and management. [ Orthopedics . 2020;43(6):e515–e522.]
ObjectivesOverlap between the distal tibia and fibula has always been quoted to be positive. If the value is not positive then an injury to the syndesmosis is thought to exist. Our null hypothesis is that it is a normal variant in the adult population.MethodsWe looked at axial CT scans of the ankle in 325 patients for the presence of overlap between the distal tibia and fibula. Where we thought this was possible we reconstructed the images to represent a plain film radiograph which we were able to rotate and view in multiple planes to confirm the assessment. ResultsThe scans were taken for reasons other than pathology of the ankle. We found there was no overlap in four patients. These patients were then questioned about previous injury, trauma, surgery or pain, in order to exclude underlying pathology.ConclusionWe concluded that no overlap between the tibia and fibula may exist in the population, albeit in a very small proportion.
We believe the improved trajectory for lag screw placement using 130-degree angled plates leads to a lower TAD and improved fixation in pertrochanteric fractures.
