RESUMO
This work aimed to characterize the clinic-pathological presentation of an outbreak of auricular and laryngeal chondritis in pigs. Visits were made to pig farms, where the clinical history was obtained, and clinical and postmortem examinations were performed. In those farms, 3% to 4% of pigs presented otohematomas, which started in the nursery and extended to the finishing phase. Moreover, some finishing pigs presented with respiratory distress, initially characterized as inspiratory dyspnea, associated by an uncommon respiratory stridor and culminating in death. Grossly, nursery piglets had enlarged ears, and on the cut surface, the cartilage was fragmented and associated with blood clots. In the finishing phase, in addition to auricular lesions, the epiglottis and arytenoid cartilages were thickened and distorted, which partially occluded the lumen. Microscopically, the laryngeal and auricular cartilages were fragmented, displayed a loss of matrix basophilia, and were surrounded by lymphohistiocytic inflammatory infiltrate, with occasional multinucleated giant cells and fibrosis. The lesions exclusively affected elastic cartilages. The disease in finishing pigs led to increased mortality and was a differential diagnosis to respiratory challenges. It was not possible to determine the factor that triggered this condition; however, a nutritional association is suspected. To the authors' knowledge, this is the first report of primary auricular and laryngeal chondritis in pigs.

A systematic literature search was performed using the PubMed, MEDLINE, and the Cochrane Library databases according to the Preferred Reporting Items for Systematic review and Meta-Analyses guidelines on May 20, 2019. The keywords used were: ankle, distal tibia, distal fibula, fracture, arthroscopic, cartilage, and chondral. The objective of this study is to systematically review the characterization of intra-articular chondral injuries of the talus, tibial plafond, medial malleolus, and lateral malleolus in patients who undergo ankle arthroscopy following ankle fracture. Studies evaluating the incidence of chondral lesions at the time of arthroscopy for ankle fractures within any timeframe were included. The incidence of intra-articular chondral lesions was recorded, the location within the ankle, ankle fracture type, time of arthroscopy, characterization of chondral injury, complications, and outcome if available. Fifteen studies with 1355 ankle fractures were included. About 738 demonstrated evidence of chondral or osteochondral lesion (54.5%). Statistical analyses were carried out with statistical software package SPSS 24.0 (SPSS, Chicago, IL). We compared incidence rates of chondral injury based on Weber classification, malleolar fracture type, and Lauge-Hansen classification, using Pearson chi-square test. For all analyses, p < .05 was considered statistically significant. We found a high incidence of intra-articular chondral lesion in the setting of ankle fractures as demonstrated by arthroscopy.

PURPOSE: The role of increased femoral antetorsion (femAT) as a contributor to patellofemoral (PF) osteoarthritis (OA) is unknown. The purpose of this study was to investigate whether increased femAT was associated with advanced cartilage degeneration in the lateral PF joint. METHODS: Patients who underwent complete radiographic workup for surgical intervention due to OA in any knee joint compartment were included. Cartilage morphology according to the International Cartilage Repair Society (ICRS) cartilage lesion classification system in the PF joint, femoral and tibial torsion, frontal leg axis, and tibial tuberosity-trochlear groove (TT-TG) distance were assessed. Increased femAT was defined as > 20° according to previous reports. RESULTS: A total of 144 patients were included. Ninety-seven patients had a femAT of < 20° and 45 of > 20°. A significant odds ratio (OR) was found for lateral retropatellar (OR 3.5; p = 0.02) ICRS grade 3 and 4 cartilage degeneration and increased femAT ≥ 20°. In the medial PF compartment, increased femAT had an inverse effect (OR 0.16; p = 0.01). No significant ORs were found for TT-TG distance, tibial torsion, or leg axis. The lateral retropatellar ICRS grade showed a linear correlation to increased femAT values. In valgus knees, isolated lateral PF OA had an even more pronounced correlation to increased femAT (p = 0.004). CONCLUSION: Increased femAT showed higher grades of lateral retropatellar cartilage degeneration, which was even more pronounced in valgus knees. LEVEL OF EVIDENCE: Cohort study: Level III.

PURPOSE: To determine the incidence and location of osteochondral lesions (OCLs) following ankle fractures as well as to determine the association between fracture type and the presence of OCLs. Up to 50% of patients with ankle fractures that receive surgical treatment show suboptimal functional results with residual complaints at a long-term follow-up. This might be due to the presence of intra-articular osteochondral lesions (OCL). METHODS: A literature search was carried out in PubMed (MEDLINE), EMBASE, CDSR, DARE and CENTRAL to identify relevant studies. Two authors separately and independently screened the search results and conducted the quality assessment using the MINORS criteria. Available full-text clinical articles on ankle fractures published in English, Dutch and German were eligible for inclusion. Per fracture classification, the OCL incidence and location were extracted from the included articles. Where possible, OCL incidence per fracture classification (Danis-Weber and/or Lauge-Hansen classification) was calculated and pooled. Two-sided p values of less than 0.05 were considered statistically significant. RESULTS: Twenty articles were included with a total of 1707 ankle fractures in 1707 patients. When focusing on ankle fractures that were assessed directly after the trauma, the OCL incidence was 45% (n = 1404). Furthermore, the most common location of an OCL following an ankle fractures was the talus (43% of all OCLs). A significant difference in OCL incidence was observed among Lauge-Hansen categories (p = 0.049). Post hoc pairwise comparisons between Lauge-Hansen categories (with adjusted significance level of 0.01) revealed no significant difference (n.s.). CONCLUSION: OCLs are frequently seen in patients with ankle fractures when assessed both directly after and at least 12 months after initial trauma (45-47%, respectively). Moreover, the vast majority of post-traumatic OCLs were located in the talus (42.7% of all OCLs). A higher incidence of OCLs was observed with rotational type fractures. The clinical relevance of the present systematic review is that it provides an overview of the incidence and location of OCLs in ankle fractures, hereby raising awareness to surgeons of these treatable concomitant injuries. As a result, this may improve the clinical outcomes when directly addressed during index surgery. LEVEL OF EVIDENCE: IV.

BACKGROUND: Slipped capital femoral epiphysis (SCFE) is a common hip problem in children. The resulting deformity can cause impingement similar to cam-type idiopathic femoroacetabular impingement (FAI). Although there are similarities between FAI and SCFE, deformity patterns, severity, and time of onset of symptoms varies, which may impact management. The purpose of this study was to describe patterns of articular cartilage damage in patients undergoing surgical hip dislocation for sequelae of SCFE in comparison to patients undergoing arthroscopic surgery for primary FAI. METHODS: Patients were identified who underwent surgical treatment for hip pain due to primary FAI (cam type) or sequelae of SCFE. Clinical data and radiographic measurements were recorded. Cartilage was assessed intraoperatively. Severity was classified using the modified Beck classification, while location was classified into 6 sectors. Statistical analysis was performed to test for differences in demographic and radiographic characteristics between the SCFE and FAI patients. χ2 or Fisher exact tests were used to evaluate trends in patterns of acetabular and femoral cartilage wear between SCFE and FAI groups. RESULTS: The SCFE group had 28 hips compared with 304 in the FAI group. SCFE patients were younger (19 vs. 32, P<0.001), had higher body mass index (30±5.9 vs. 24±4.8, P<0.001), and were more often male (61% vs. 27%, P<0.001). Deformity severity based on α-angle was higher in the SCFE group [AP 74 vs. 55 (P=0.001) and Dunn 72 vs. 58 (P<0.001)]. There were no significant differences with regards to lateral center edge angle, anterior center edge angle, or Tonnis angle. In both groups the most common locations for cartilage lesions in both groups were the anterior peripheral and superolateral peripheral regions with fewer but more widely distributed femoral head lesions. The SCFE group had higher rates of femoral head and superolateral central cartilage lesions compared with the FAI group. There was no statistical difference between high-grade femoral or acetabular cartilage lesions between groups. CONCLUSIONS: Patients with SCFE were younger at the time of surgery and presented with more severe deformity based on radiographic α-angle compared to patients with FAI. Our results suggest higher prevalence of femoral head lesions and more diffuse cartilage injury in patients with SCFE. This study can be used to support early surgical intervention in patients with symptomatic sequelae of SCFE due to risk of premature joint damage. LEVEL OF EVIDENCE: Level III-prognostic study.

INTRODUCTION: Despite successful osteosynthesis, some patients report residual symptoms after ankle fractures. One of the reasons behind the postoperative complaints might be traumatic concomitant chondral lesions (CL) and/or osteochondral lesions (OCL) within the ankle joint. The study aims to systematically review the incidence of CL and/or OCL in ankle fractures and to assess their effect on the clinical outcome. MATERIALS AND METHODS: This work was conducted according to PRISMA checklists. A systematic literature search was performed using following keywords: "Ankle Fractures" OR "Trimalleolar Fracture" OR "Bimalleolar Fracture" OR "Maisonneuve fracture" OR "Malleolus Fracture" AND "Cartilage" OR "Cartilage Diseases" OR "Cartilage, Articular" OR "chondral" up to March 2020. The identified articles were analysed to determine the incidence of CL and/or OCL. Included studies in the meta-analysis assessed possible cartilage damage through arthroscopy or MRI immediately after traumatic ankle fractures and described the postoperative clinical outcome. RESULTS: The search identified a total of 111 publications; 19 described the incidence of CL and/or OCL after ankle fractures; six met the criteria to be included in the meta-analysis: five (n = 293) diagnosed CL and/or OCL through arthroscopy during ORIF and one study (n = 153) used preoperative MRI. The clinical outcome was evaluated in four studies (n = 177) using AOFAS score and in two (n = 269) using FAOS score. The mean incidence of arthroscopically detected CL and/or OCL was 65 ± 21% [95% CI 53.9 to 76.72]. The cumulative meta-analysis sample size comprised a total of 400 Patients (170 with and 230 without CL and/or OCL) available for a mean follow-up of 23.9 ± 11.5 months [95% CI 11.79 to 36.07]. The average age was 44.3 ± 5.5 years [95% CI 38.57 to 50.13]. The meta-analysis revealed a mean AOFAS score of 91.2 ± 4.8 [95% CI 83.53 to 98.93] with versus 94.4 ± 4.7 [95% CI 86.81 to 102.07] without CL and/or OCL (p = 0.15) and a mean FAOS score of 73.2 ± 11.31 [95% CI - 28.44 to 174.85] with versus 79.0 ± 18.4 [95% CI - 86.77 to 244.87] without CL and/or OCL (p = 0.18). CONCLUSIONS: CL and/or OCL appear very frequently after ankle fractures. A tendency towards a favourable short- to mid-term clinical outcome was noticed in ankle fractures without CL and/or OCL, however without reaching statistical significance. LEVEL OF EVIDENCE: Level I.

BACKGROUND: Focal cartilage defects (FCDs) in the knee joint has a high prevalence. A broad range of treatment options exists for symptomatic patients. Knowledge of patient compensation claims following surgical treatment of FCDs is missing. The purpose of this study is to evaluate compensation claims filed to the Scandinavian registries for patient compensation following treatment of FCDs in the knee joint from 2010 to 2015 and identify possible areas of improvement. METHODS: A cross-sectional study design was used to obtain all complaints following surgical treatment of FCDs from the Scandinavian registries from 2010 to 2015. Data such as age, gender, type of treatment, type of complaint, reason of verdict and amount of compensation were collected and systematically analyzed. RESULTS: 103 patients filed a compensation claim. 43 had received debridement (41.7%), 54 microfracture (MF) (52.4%), 3 mosaicplasty (2.9%) and 3 autologous chondrocyte implantation (ACI) (2.9%). Of the 103 claims, 36 were granted (35%). 21 following debridement (58.3%), 13 after MF (36.1%), 1 following mosaicplasty (2.8%) and 1 after ACI (2.8%). The most common reason for complaint was infection (22.1%), of which 89% were granted. The average compensation was 24.457 (range 209 - 458.943). CONCLUSION: Compensation claims following surgical treatment of knee cartilage injuries in Scandinavia are rare. Establishing nationwide cartilage registries can add further knowledge on this troublesome disease.

OBJECTIVE: The aim of this study was to detect the prevalence of soft tissue calcifications in the head and neck using cone beam computed tomography (CBCT) and to determine their clinical importance. SUBJECTS AND METHODS: Soft tissue calcifications in the head and neck region were retrospectively evaluated in 1557 CBCT images obtained between 2013 and 2015. The findings were categorized as follows: tonsillolith (calcified tonsil), carotid artery calcification (CAC), sialolith (salivary stone), calcified triticeous cartilage (CTC), calcified lymph node (CLN), rhinolith, antrolith, calcification of the superior cornu of the thyroid cartilage (CSCTC), calcified stylohyoid ligaments (CSL), myositis ossifican, osteoma cutis, and intracranial calcification. A Chi-square test was performed for categorical variables. In the 1557 CBCT images, 520 (33.4%) contained had at least one soft tissue calcification in the head and neck region. RESULTS: Tonsilloliths (18.8%) were the most prevalent soft tissue calcification, followed by CTC (5.8%), CAC (4.3%), intracranial calcifications (3.9%), CSL (3.7%), CSCTC (2.1%), osteoma cutis (1%), sialoliths (0.7%), antroliths (0.5%), myositis ossificans (0.4%), rhinoliths, and CLN (0.2%). CONCLUSION: There was a high prevalence of soft tissue calcifications in the head and neck region on CBCT images. Tonsilloliths were the most common type of calcification. CBCT imaging may aid the diagnosis and assessment of these calcifications.

PURPOSE: The purpose of this study was to utilize data from the German Cartilage Registry (KnorpelRegister DGOU) to examine the hypothesis that degenerative cartilage defects of the patellofemoral joint are associated with more severe clinical symptoms compared to trauma-related defects. METHODS: All patients with isolated focal cartilage defects of the patellofemoral joint registered in the German Cartilage Registry until May 2017 were included in the study. Patients with previous surgery of the ipsilateral knee were excluded. Baseline data including etiology (traumatic, degenerative), size, location and ICRS grade of the cartilage defects as well as the duration of symptoms were analyzed. Clinical symptoms were evaluated by means of the numeric analog scale (NAS) for pain and the Knee injury and Osteoarthritis Outcome Score (KOOS). Group comparisons were performed using the Mann-Whitney-U test along with the Chi-squared test and Fisher's exact test. A bivariate correlation analysis and a multivariable linear regression analysis were performed to investigate the association between the defect characteristics and the clinical scores. RESULTS: A total of 423 patients (203 traumatic and 220 degenerative defects) were included. Isolated degenerative cartilage defects were found to have significantly more trochlear locations (28% vs. 18%; p = 0.006), significantly less ICRS grade 4 lesions (50% vs. 73%; p = 0.002) and a significantly smaller defect size [median 300 (IQR 105-400) vs. 300 (200-400) mm2] when compared to those from traumatic etiology. Traumatic defects showed significantly better KOOS-ADL [77 (60-90) vs. 69 (56-82); p = 0.005], KOOS-pain [69 (56-81) vs. 61 (47-75); p = 0.001] and NAS [2 (1-5) vs. 4 (1-6); p = 0.005] scores compared to degenerative defects. The correlation analysis revealed only weak correlations between the quantitative defect characteristics and clinical scores. CONCLUSIONS: Degenerative isolated cartilage defects in the patellofemoral joint are associated with more severe clinical symptoms in comparison to trauma-related defects. Additionally, they show a larger variance regarding their location with more trochlear defects. LEVEL OF EVIDENCE: III.

PURPOSE: To evaluate the factors influencing the baseline Knee Injury and Osteoarthritis Outcome Score (KOOS) in patients with knee cartilage defects and planned cartilage repair surgery and to provide baseline KOOS data from a large patient population. MATERIAL AND METHODS: Between October 2013 and April 2017, a total of 2815 patients assigned for cartilage repair surgery were included into the German Cartilage Registry (KnorpelRegister DGOU) and their data were analyzed for the present study. Multivariate regression model and ANOVA were used to detect patient- and defect-specific factors with an influence on baseline KOOS. In addition, KOOS baseline data was calculated and compared according to these parameters. RESULTS: Sex, age, body mass index (BMI), and smoking status were revealed as patient-specific factors, and defect location and the number of previous knee and cartilage operations were revealed as defect-specific factors with a significant influence on baseline KOOS. Most subscores were affected in accordance with the total KOOS. Interestingly, defect ICRS grade, defect size, and symptom duration had no significant influence. The mean baseline KOOS was 56.7 (± 17.9). Men had significantly higher mean overall KOOS (60 ± 17.3 vs. 51.8 ± 17.6, p < 0.001) than women, and patients with a BMI over 30 and smokers scored significantly lower (58.07 ± 17.67 vs. 50.32 ± 17.29, p < 0.001; 57.64 ± 17.86 vs. 53.59 ± 18.06, p < 0.001). Patients with two or more previous knee operations as well as patients with more than one previous cartilage procedure also showed significantly lower overall KOOS (57.19 ± 17.89 vs. 54.56 ± 17.58, p < 0.001; 57.68 ± 18.01 vs. 52.72 ± 17.58, p < 0.001). CONCLUSION: Several factors influencing baseline KOOS data in patients with knee cartilage defects assigned for cartilage repair surgery could be detected. Their individual influence in the multivariate linear regression model was not very strong. Baseline data according to these criteria is presented in this paper.

INTRODUCTION: The purpose of this systematic review and meta-analysis was to analyze and compare the rate of secondary meniscus and cartilage lesions diagnosed at different time points of ACL reconstruction. MATERIALS AND METHODS: A systematic search for articles comparing the rate of secondary meniscus and cartilage lesions diagnosed at different time points of ACL reconstruction was performed. PubMed central was the database used for the literature review. RESULTS: Forty articles out of 1836 were included. In 35 trials (88%), there was evidence of a positive correlation between the rate of meniscus and/or cartilage lesions and the time since ACL injury. This correlation was more evident for the medial meniscus in comparison with the lateral meniscus. In particular, a delay of more than 6 months was critical for secondary medial meniscus injuries [risk ratio 0.58 (95% CI 0.44-0.79)] and a delay of more than 12 months was critical for cartilage injuries [risk ratio 0.42 (95% CI 0.29-0.59)]. Additionally, there is evidence that the chance for meniscal repair decreases as the time since ACL rupture increases. CONCLUSION: Chronic instability in the ACL-deficient knee is associated with a significant increase of medial meniscus injuries after 6 months followed by a significant increase of cartilage lesions after 12 months.

OBJECTIVE: To determine the relationship of meniscal damage to magnetic resonance imaging (MRI) features of compartment-specific patellofemoral joint (PFJ) osteoarthritis (OA) at baseline and 2 years later. METHOD: Individuals from a prospective cohort of individuals aged 50-79 with or at risk of knee OA were included. At the 60-month and 84-month study visit, Whole-Organ MRI Score (WORMS) was used to assess meniscal tears and extrusions as well as cartilage damage and bone marrow lesions (BMLs) in the medial and lateral patella and trochlea. Worsening of structural features was defined as any increase in WORMS score from 60 to 84 months. Logistic regression was used to determine the cross-sectional and longitudinal relation of meniscus damage to features of compartment-specific PFJ OA. RESULTS: Relative to knees without lateral meniscal pathology at baseline, those with grades 3-4 lateral meniscal tear and extrusion had greater risk of worsening of cartilage damage in the lateral PFJ 2 years later (Risk ratio: 1.7 [95% CI: 1.1-2.7) and (1.7 [1.2-2.5]), respectively. Relative to those without medial meniscal pathology at baseline, those with grades 1-2 (0.6 [0.4-0.9]) and 3-4 (0.7 [0.5-1.0]) medial meniscal tears had lower risk of worsening of BMLs in the medial PFJ 2 years later. CONCLUSION: Meniscal tear and extrusion are associated with increased risk of medial and lateral PFJ OA and more severe meniscal pathology is associated with worsening of PFJ OA 2 years later. Lateral meniscal pathology appears to be more detrimental to the lateral PFJ.

OBJECTIVE: To determine the prevalence of soft tissue calcifications in cone beam computed tomography (CBCT) scans with different fields of view (FOV) and to assess its relation with the clinical relevance of the CBCT findings. MATERIAL AND METHODS: One thousand CBCT scans were grouped according to FOV's size and region scanned (MX-FOV, maxilla; MD-FOV, mandible; and MM-FOV, maxilla/mandible) and evaluated for the presence of soft tissue calcifications. Laterality and length of the elongated styloid processes (ESP) were also assessed. RESULTS: Eight hundred and eighty-two soft tissue calcifications were detected in 626 (62.6%) patients. MM-FOV presented the highest prevalence (76.8%), followed by MD-FOV (60.6%) and MX-FOV (57.2%). ESP and tonsillolith were the most frequent calcifications. Calcifications requiring treatment or not and those in need of follow-up accounted for 6.9%, 92.7%, and 0.3% of cases, respectively. There was no association between calcifications and subjects' gender or age (p > .05). Most cases of ESP occurred bilaterally and were longer in males (p < .05). CONCLUSIONS: There is a high prevalence of soft tissue calcifications in CBCT, and ESP and tonsilloliths are the most common types in all evaluated FOVs. While most cases do not require treatment, we emphasize the importance of detailed CBCT assessment for its diagnosis.

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: To describe the demographics, clinical presentation, and functional outcomes of fibrocartilaginous embolic myelopathy (FCEM). SETTING: Academic inpatient rehabilitation unit in the midwestern United States. METHODS: We retrospectively searched our database to identify patients admitted between January 1, 1995 and March 31, 2016, with a high probability of FCEM. Demographic, clinical, and functional outcome measures, including Functional Independence Measure (FIM) information was obtained by chart review. RESULTS: We identified 31 patients with findings suggestive of FCEM (52% male), which was 2% of the nontraumatic spinal cord injury population admitted to inpatient rehabilitation. The age distribution was bimodal, with peaks in the second and sixth-to-seventh decades. The most common clinical presentation was acute pain and rapid progression of neurologic deficits consistent with a vascular myelopathy. Only three patients (10%) had FCEM documented as a diagnostic possibility. Most patients had paraplegia and neurologically incomplete injuries and were discharged to home. Nearly half of the patients required no assistive device for bladder management at discharge, but most were discharged with medications for bowel management. Median FIM walking locomotion score for all patients was 5, but most patients were discharged using a wheelchair for primary mobility. Median motor FIM subscale score was 36 at admission and 69 at discharge, with a median motor efficiency of 1.41. CONCLUSIONS: FCEM may be underdiagnosed and should be considered in those with the appropriate clinical presentation, because their functional outcomes may be more favorable than those with other causes of spinal cord infarction.

BACKGROUND: The purpose of this study was to analyze the association between the prevalence of meniscal and chondral lesions and the timing of surgery in patients undergoing primary anterior cruciate ligament (ACL) reconstruction to determine a safe time for surgery. METHODS: This retrospective study involved 226 patients (91 females and 135 males; median age, 29 years) undergoing primary ACL reconstruction. Time interval from ACL injury to surgery (median, 4 months; range, 1-420 months) and concomitant meniscal and cartilage lesions in ACL reconstruction were reviewed. Receiver operating characteristic (ROC) curve analysis was used to determine the precise threshold interval to surgery to prevent meniscal or cartilage lesions. The risk of lesion occurrence after each cutoff period was determined using odds ratio (OR). RESULTS: The incidences of medial meniscus (MM), lateral meniscus (LM), and cartilage lesions were 43.8%, 32.7%, and 27.4%, respectively. ROC analysis revealed that patients who waited for more than 6, 4, and 5 months for ACL reconstruction had a significantly greater risk of associated MM, LM, and chondral lesions, respectively. Patients who underwent ACL reconstruction ≥7 months after injury had OR of 4.1 (p < 0.001) for the presence of MM lesion as compared with those who underwent reconstruction within 6 months. Similarly, patients who underwent ACL reconstruction ≥5 months after injury had OR of 1.9 (p = 0.023) for the presence of LM lesion as compared with those who underwent reconstruction within 4 months, and patients who underwent ACL reconstruction ≥6 months after injury had OR of 2.9 (p < 0.001) for chondral lesion as compared with those who underwent reconstruction within 6 months. CONCLUSION: ACL reconstruction should be performed within approximately 6 months after the injury to prevent associated meniscal or chondral lesions.

Background: the main goal of the study was to investigate the prevalence of the articular cartilage defects (ACD) in the patellofemoral (PF) region of the knee joint based on the anatomical shapes of patella and its impact on the level of physical activity in the population needing arthroscopic procedures for all types of pathologies in the knee. Methods: The articular cartilage status of the PF region was obtained from 1098 arthroscopic procedures of the knee joint. The ACD were correlated to Wiberg's shape of the patella and classified according to the degree, size and depth of the ACD in the PF region using the ICRS (International Cartilage Repair Society) system: group I consisting of patients with Wiberg type I shape (W1), group II-patients with Wiberg type II shape (W2) and group III-patients with Wiberg type III shape (W3). The Tegner physical activity scale was used to evaluate the physical activity of the patients. Results: The mean of ACD size (PF region) in the W3 group was 3.10 ± 0.99 cm², which was a statistically significantly larger area in comparison with the W1 (1.90 ± 0.63 cm²; p < 0.0000) and W2 (1.95 ± 0.71 cm²; p < 0.0000). The patients from the W3 group (mean 3.10 ± 0.99) were less physically active (<4 Tegner) compared to the W2 group (mean of 4.48 ± 0.88; p = 0.004) and W1 group (mean of 4.55 ± 0.72; p = 0.002). Conclusions: The patients with the Wiberg type III patella shape had a higher incidence and larger size of ACD in the PF of the knee compared to the groups of Wiberg type I and II. Wiberg III patients with a lower level of physical activity had a larger size of ACD in the PF joint.

Chondrodermatitis nodularis helicis (CNH) is characterized by a tender nodule located on the helix or antihelix. Age groups impacted by CNH vary from study to study, but the majority of studies report an average age range from 50 to 80 years. Various treatment options have been described in the literature, including surgical techniques, laser therapy, curettage, topical and intralesional corticosteroids, and pressure relieving techniques. The main goal of therapy is to reduce pain and improve clinical appearance. In recent years, new therapies have been described for CNH with great results and lower recurrence rates. It is our hope that this review can serve as a reference for both practitioners and patients looking to treat CNH.

BACKGROUND: Norway has no prospective surveillance system to monitor the outcome of knee cartilage surgery. In 2004 the Norwegian Registry of Knee Ligament (NKLR) was successfully established, and has yielded useful information on the treatment of patients with both knee ligament and combined knee injuries. Patients with focal cartilage defects (FCDs) in their knees have reduced function and the treatment is difficult. There are geographical variations in treatment, and the generalizability from randomized controlled studies is low. These patients would benefit from a standardized long-time follow-up through a cartilage surgery register. The aim of the present study was to describe the development and report baseline challenges during the setting up of a pilot of a knee cartilage surgery register. METHODS: The study was designed as a prospective cohort study in the form of a register. Patients with full-thickness FCDs in the knee with International Cartilage Repair Society (ICRS) grade 3-4 on arthroscopy were included. The pilot included two hospitals; Oslo University Hospital (OUS), Ullevål and Akershus University Hospital (Ahus). RESULTS: We registered 58 patients with isolated FCDs, whereas 16 additional patients with full-thickness FCDs were registered through the NKLR. The patient cohort of patients with isolated FCDs consisted of 65% men and had a mean age of 29.8 years. The data are incomplete and the compliance varies from 18 to 73%. The distribution of mean KOOS scores were similar to previous patient cohorts with FCDs, with low scores for the KOOS Sport/Recreation and Quality of Life subscales. CONCLUSION: The level of compliance demonstrated a large difference between the two participating hospitals. The compliance for the isolated FCDs were low in both locations, although it reached an acceptable level in one hospital when patients with combined injuries from the NKLR were included. The forms were incompletely filled out by the surgeons postoperatively and need to be revised prior the establishment of a nation-wide register.

INTRODUCTION: This case-control study compares patients with healthy elbows to a group of symptomatic patients with cartilage damage/osteoarthritis. MATERIALS AND METHODS: The control group (n = 126) was recruited during routine medical examinations of patients (general medical offices). Included in the case group were a total of 92 patients who were undergoing arthroscopy as a result of chronic elbow discomfort. All patients were questioned with regard to occupational stress and athletic stress. RESULTS: A significantly increased risk of cartilage damage/osteoarthritis was found with subjectively perceived increased stress in occupational settings: OR = 3.8 (95% CI 2.1-6.7); p < 0.001; for the individual stresses of the elbow joint in occupational settings, the following severities in effects were found: Exposure to heavy work OR = 3.9 (95% CI 2.2-6.8); Force OR = 3.7 (95% CI 2.1-6.5); Vibration OR = 4.6 (95% CI 2.5-8.5); Repetition OR = 9.2 (95% CI 3.6-23.3); p < 0.001. Elbow-stressing sport types represent a potential risk factor for the development of cartilage damage/osteoarthritis of the elbow joint: OR = 2.5 (95% CI 1.3-4.7); p = 0.003. CONCLUSIONS: Cartilage damage/radiographic osteoarthritis of the elbow joint are rare with respect to the overall prevalence of osteoarthritis. In the large number of patients with cartilage damage/radiographic osteoarthritis of the elbow joint, occupational or athletic stress factors and injuries sustained, in addition to other causes (rheumatism, gout), can prove as possible causes of these as secondary to symptomatic forms of osteoarthritis.

PURPOSE: Femoroacetabular impingement (FAI) has been well described in recent years as one of the major causes of hip pain potentially leading to acetabular labral tears and cartilage damage, which may in turn lead to the development of early degenerative changes. More recently, extra-articular patterns of impingement such as the anterior inferior iliac spine (AIIS)/subspine hip impingement have gained focus as a cause of hip pain and limitation in terminal hip flexion and internal rotation. The purpose of this study was to evaluate the prevalence of low AIIS in patients undergoing hip arthroscopy and to characterize the concomitant intra-articular lesions. METHODS: Between November 2011 and April 2013, 100 consecutive patients underwent hip arthroscopy for various diagnoses by a single surgeon. After intra-operative diagnosis of low AIIS was made, a comprehensive review of the patients' records, preoperative radiographs, and intra-operative findings was conducted to document the existence and location of labral and chondral lesions. RESULTS: Twenty-one (21 %) patients had low AIIS. There were 13 males (mean age 38.4 years) and eight females (mean age 35.5 years). Eight patients had pre-operative radiographic evidence of low AIIS. All patients had a labral tear anteriorly, at the level of the AIIS; 17 had chondrolabral disruption and 17 had chondral lesions in zone two (antero-superior); and four patients had lesion in zones two and three. CONCLUSIONS: Low AIIS is a common intra-operative finding in hip arthroscopy patients. Characteristic labral and chondral lesions are routinely found in a predictable location that effaces the low AIIS. Level of Evidence-Level IV, Case Series.
