Routine Photography of Injuries: A Comparison Between Smartphone Cameras and Digital Single-Lens Camera-A Pilot Study.

ABSTRACT: Ten lesions were photographed with an entry-level (HUAWEI P smart 2019), a midrange (Samsung Galaxy S8) and a high range (Apple Iphone XR) smartphone camera and with a digital single-lens camera (DSLC). Images were independently rated by 3 pathologists, based on comparison to the real lesion and "visual impact." Difference of perceptual lightness coordinates between smartphones and the criterion standard (DSLC) was calculated.The highest ranking for adherence to reality was obtained with DSLC, while the highest ranking for visual impact was obtained with the Iphone. The color representation better reflecting the criterion standard (DSLC) was obtained for the entry-level smartphone.All the devices allow to assess the general features (ie, the color, the shape, and the main characteristics) of an injury during a forensic autopsy. However, results might be different when photos are obtained in suboptimal, such as low-light, conditions. Moreover, images acquired through a smartphone camera might be unsuitable for later image exploitation, such as enlargement of a portion of the image to magnification of a detail, which seemed not relevant when the photo was shot. Only a raw image, acquired using a dedicated camera and deactivating images manipulation software, might allow the preservation of the true data.

Ten-Year Survivorship, Patient-Reported Outcome Measures, and Patient Acceptable Symptom State After Over-the-Top Hamstring Anterior Cruciate Ligament Reconstruction With a Lateral Extra-articular Reconstruction: Analysis of 267 Consecutive Cases.

BACKGROUND: Long-term patient-reported outcome measures (PROMs) and predictors of success or failure after anterior cruciate ligament (ACL) reconstruction are not fully understood, especially when combined with a lateral extra-articular reconstruction. PURPOSE: To assess the long-term PROMs, revision rate, and predictors of success or failure after ACL reconstructions using an over-the-top surgical technique with single-bundle hamstring tendon autografts and a lateral extra-articular reconstruction. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: The study cohort consisted of 267 consecutive patients (mean age, 30.7 years) who underwent ACL reconstruction with an over-the-top surgical technique with single-bundle hamstring tendon autografts and a lateral extra-articular augmentation between November 2007 and May 2009. The number of subsequent ACL revisions and reoperations were recorded. Subjective clinical status was assessed with PROMs-specifically, the Knee injury and Osteoarthritis Outcome Score (KOOS), Lysholm, Tegner, and visual analog scale for pain-at a minimum follow-up of 10 years. RESULTS: Overall, 3% of patients underwent ACL revision, with a 10-year survival rate of 96.3%. High sport activity (hazard ratio, 6.9; P = .285) and concomitant meniscal lesion (hazard ratio, 2.6; P = .0487) were predictors of ACL revision or new meniscectomy. The mean ± SD Lysholm score was 94.1 ± 10.8, while that for the visual analog scale for pain was 0.2 ± 0.9 at rest and 2.1 ± 2.6 during activity. KOOS subscale scores were as follows: 95.7 ± 8.1 for Pain, 92.5 ± 10.5 for Symptoms, 98.4 ± 7.4 for Activities of Daily Living, 90.7 ± 17.2 for Sport, and 91.2 ± 17.1 for Quality of Life; respectively, 88%, 99%, 81%, 89%, and 91% of patients achieved the Patient Acceptable Symptom State. Female sex and chondropathy with Outerbridge grade ≥2 were predictors of worse KOOS subscales. Overall, 82% of patients returned to sport, and 57% were still participating at the 10-year evaluation. CONCLUSION: ACL reconstruction with an over-the-top surgical technique with single-bundle hamstring autografts and a lateral extra-articular reconstruction provided satisfactory results in terms of function, symptoms, sports, and quality of life in 80% to 90% of patients after 10 years. Long-term survivorship was 96%. Sport participation declined from 82% postoperatively to 57% at long-term follow-up. A concomitant medial meniscal lesion was a predictor of higher risk of ACL failure or new meniscal lesion, while advanced chondropathy and female sex were predictors of higher pain, lower function, and poor quality of life scores.

More Than a 2-Fold Risk of Contralateral Anterior Cruciate Ligament Injuries Compared With Ipsilateral Graft Failure 10 Years After Primary Reconstruction.

BACKGROUND: Failure of anterior cruciate ligament (ACL) reconstruction or an injury to the ACL in the contralateral knee represents a devastating event for patients, especially those young and physically active. However, controversies are still present regarding long-term failure rates and risk factors. PURPOSE: To assess the long-term rate of ipsilateral graft failure and contralateral ACL injuries after ACL reconstruction performed at a single center using the same surgical technique with a hamstring autograft and to investigate the effect of sex, age, and preinjury activity level as predictors of second ACL injuries. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: The study cohort consisted of 244 consecutive patients (mean age, 30.7 years) who underwent ACL reconstruction with a single bundle plus lateral plasty technique using the hamstring tendon between November 2007 and May 2009. The number of subsequent ACL injuries (ipsilateral ACL revision or contralateral ACL reconstruction) was determined at a minimum follow-up of 10 years. Survivorship of either knee and subgroup analysis included sex, age, preoperative Tegner activity level, timing of ACL reconstruction, body mass index, and smoking status. RESULTS: Ipsilateral ACL revision was performed in 8 (3.4%) patients and contralateral ACL reconstruction in 19 (7.8%) patients. Only 1 patient had both ipsilateral and contralateral injuries. No predictors were found for ipsilateral ACL revision, while age <18 years and preoperative Tegner level ≥7 had a higher risk of contralateral ACL reconstruction. The highest rate of a second ACL reconstruction procedure was in young (<18 years) and active (Tegner ≥7) patients, in whom the 10-year survival of either knee was 61.1%. Six years after primary ACL reconstruction, the rate of contralateral ACL reconstruction was significantly higher than that of ipsilateral ACL revision (hazard ratio, 2.4-3.6). CONCLUSION: In the long term, a second injury to either the ipsilateral or the contralateral knee in young and active populations could reach 40%, with a more than double-fold risk of contralateral ACL reconstruction compared with ipsilateral ACL revision.
