Category: Ankle; Arthroscopy Introduction/Purpose: Autologous osteochondral transplantation (AOT) is commonly used in the treatment of osteochondral lesions (OCL) of the talus. There is limited data comparing gender differences in the incidence, presentation, and outcomes following AOT. The purpose of this study is to compare these differences between male and female patients. Methods: Eighty-five consecutive patients who underwent AOT were retrospectively reviewed. Patients were divided into two groups based on gender. Demographic data and OCL defect characteristic data were recorded. Functional outcomes were assessed pre- and post-operatively using the Foot and Ankle Outcome Score (FAOS). The Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score was used to assess cartilage incorporation. The mean clinical follow-up was 47.2 months, with mean MRI follow-up of 24.8 months. Results: Fifty-five (65%) males and 30 (35%) females were included. OCL defect size was significantly larger in men (112.8mm2) when compared with women (88.7mm2) (p<0.0001). Male patients had a significantly longer duration of symptoms (p<0.001) and OCLs were more likely traumatic in nature (p=0.0006) when compared with female patients. Mean FAOS improved pre- to postoperatively from 50 to 81(P < .001) with a statistically significant increase in men (p<0.0001). The mean MOCART score was 82.1 and 86.7 in male and female patients, respectively (p<0.0001). Lesion size was negatively correlated with MOCART score (r = -0.36,P = .004). No differences were found in knee donor site morbidity, complication rate, or revision surgery. Conclusion: Our study demonstrates that male patients typically present with talar OCLs that are larger in size, traumatic in nature, and with longer symptom duration when compared with female patients. In addition, male patients had greater improvement in FAOS scores following AOT. Therefore, understanding these differences may influence the management and treatment of talar OCLs in male and female patients.

Category: Ankle Introduction/Purpose: Operative management for osteochondral lesions of the talus (OLT) can be broadly divided into reparative techniques, including bone marrow stimulation (BMS), and replacement techniques, including autologous osteochondral transplantation (AOT). Predictors of outcome of BMS have been established as lesion size, containment of the lesion, and previous surgery. Predictors of outcome of AOT or allograft transplantation have been established as body mass index and the requirement for greater than 2 grafts. However, containment of the lesions has not been assessed as a predictor of outcome in patients undergoing AOT to date. Therefore, the purpose of the current study is to clarify the effect of the containment of OLT on clinical and radiological outcomes in patients who underwent AOT procedure for the treatment of OLT. Methods: A retrospective cohort study comparing patients with contained type and uncontained type OLT was undertaken, to include all patients who underwent AOT procedure for the treatment of OLT between 2006 and 2014. Analyses were performed by grouping the patients according to the containment type, location, and both the type of containment and location. Clinical outcomes were evaluated using the Foot and Ankle Outcome Scores (FAOS) and Short-Form 12 (SF-12) preoperatively and at the final follow-up. Magnetic resonance imaging (MRI) at 2 years follow-up was evaluated with modified magnetic resonance observation of cartilage repair tissue (MOCART) score. Comparisons between groups were made with the Man-Whitney U test for continuous variables and the?2 or Fisher exact test for categorical variables. Multivariate regression models were used to evaluate factors affecting postoperative FAOS, SF-12 and MOCART scores. A value of p < 0.05 was considered statistically significant. Results: Ninety-four patients were included, with 31 with a contained type OLT and 63 with an uncontained type OLT. The median follow-up time were 45 months in contained type and 52 months in uncontained type. The mean FAOS and SF-12 improved significantly after surgery in both contained and uncontained lesions (p<0.001). The mean postoperative FAOS in contained type was higher than uncontained type (89.5 vs 80.2, p=0.009), but no significant differences were found between uncontained and contained type in postoperative SF-12 and MOCART score. The multivariate regression models showed that patients with contained type OLT had approximately 10 points better scores in FAOS compared to uncontained type (p=0.006) (Table 1). Patients who had previous microfracture performed worse postoperative FAOS than those who did not (p =0.004). Conclusion: Patients with contained type OLT experienced better clinical outcomes than those with uncontained type OLT following AOT procedure for the treatment of OLT. However, the AOT procedure still provided good clinical and MRI outcomes in both contained type and uncontained type OLT at the mid-term follow-up.

Background: Uncontained-type osteochondral lesions of the talus (OLTs) have been shown to have inferior clinical outcomes after treatment with bone marrow stimulation. While autologous osteochondral transplantation (AOT) is indicated for larger lesions, no study has reported on the prognostic significance of the containment of OLTs treated with the AOT procedure. Purpose: To clarify the effect of the containment of OLTs on clinical and radiological outcomes in patients who underwent AOT for OLTs. Study Design: Case control study; Level of evidence, 3. Methods: A retrospective cohort study comparing patients with contained-type and uncontained-type OLTs was undertaken to include all patients who underwent AOT for the treatment of OLTs between 2006 and 2014. Analyses were performed by grouping the patients according to the containment type. Clinical outcomes were evaluated using the Foot and Ankle Outcome Score (FAOS) and the 12-Item Short Form Health Survey (SF-12) preoperatively and at final follow-up. Magnetic resonance imaging (MRI) at 2 years’ follow-up was evaluated with the modified magnetic resonance observation of cartilage repair tissue (MOCART) score. Multivariate regression models were used to evaluate factors affecting postoperative FAOS, SF-12, and MOCART scores. Results: Ninety-four patients were included: 31 patients with a contained-type OLT and 63 patients with an uncontained-type OLT. The median patient age was 34 years (interquartile range [IQR], 28-48 years) in the contained-type group and 36 years (IQR, 27-46 years) in the uncontained-type group. The median follow-up time was 45 months (IQR, 38-63 months) in the contained-type group and 52 months (IQR, 40-66 months) in the uncontained-type group. The median FAOS and SF-12 scores improved significantly after surgery in both contained-type and uncontained-type lesions ( P < .001). The median postoperative FAOS score of patients with contained-type OLTs was higher than that of patients with uncontained-type OLTs (91.7 vs 85.0, respectively; P = .009), but no significant differences were found between the contained-type and uncontained-type groups for postoperative SF-12 and MOCART scores. The multivariate regression models showed that patients with contained-type OLTs had an approximately 10-point better score on the FAOS compared with patients with uncontained-type OLTs ( P = .006). There was a nonsignificant trend for the rate of cystic occurrence in uncontained-type OLTs to be higher than that of contained-type OLTs (55.6% vs 38.7%, respectively; P = .125). Conclusion: Patients with contained-type OLTs experienced better clinical outcomes than those with uncontained-type OLTs after AOT for the treatment of OLTs. However, the AOT procedure still provided good clinical and MRI outcomes in both contained-type and uncontained-type OLTs at midterm follow-up.

Ligoniai ir metodai 1998–2002 metais KMU Ortopedijos ir traumatologijos klinikoje atliktos 87 autologinės mozaikinės transplantacijos operacijos esant kelio sąnario kremzlės ir kaulo pažeidimams. Pacientų amžiaus vidurkis operacijų metu buvo 24,74 ± 7,20 metų (14–40 metų). Simptomai vidutiniškai truko 21,32 ± 5,57 mėnesio, o pacientai įvertinti praėjus vidutiniškai 24,4 mėnesio (nuo 12 iki 60 mėnesių) po operacijos. Rezultatai apibendrinti naudojant ICRS (International Cartilage Repair Society) anketą, 13 (15%) atvejų – remiantis kartotinių artroskopijų metu atliktu makroskopiniu įvertinimu, 9 (11%) atvejais – histologiniu tyrimu, 57 (67%) atvejais – BMR ir visais atvejais – rentgeno tyrimais. Visus anketinius įvertinimus atliko nepriklausomas gydytojas ortopedas prieš operacijas ir po operacijų praėjus dvylikai, dvidešimt keturiems, trisdešimt šešiems, keturiasdešimt aštuoniems ir šešiasdešimčiai mėnesių. Nepriklausomi nuo tyrimo gydytojai, radiologas ir patologas, atliko visus BMR ir histomorfologinius įvertinimus. Rezultatai Praėjus vidutiniškai 24,4 mėnesio po mozaikinės transplantacijos, ICRS anketos būdu nustatytas klinikinis rezultatų pagerėjimas (p < 0,05). Funkcinis ir objektyvus įvertinimas pagal ICRS anketą buvo toks: 93% atvejų gauti geri ir labai geri operacinio gydymo rezultatai, kitais atvejais (7%) gydymo rezultatai buvo patenkinami. Kartotinių artroskopijų metu (remiantis ICRS protokolu), po operacijų praėjus vidutiniškai 12,4 mėnesio, 11 (84%) iš 13 atvejų buvo nustatytas geras ir labai geras sąnario kremzlės makroskopinis atsitaisymas. Sąnario kremzlės biopsijos ir histologinis tyrimas buvo atliktas 11% pacientų, ir daugumos jų (remiantis ICRS protokolu) sąnario kremzlės ir pokremzlinio kaulo atitaisymo koeficientas buvo geras. BMR tyrimas parodė, kad 94% pacientų sąnario paviršius atkurtas gerai arba labai gerai. Išvados Mūsų tyrimas parodė, kad po mozaikinės autologinės transplantacijos praėjus vidutiniškai 24,4 mėnesio (nuo 12 iki 60 mėn.) fiziškai aktyvių pacientų, kuriems buvo pažeista kelio sąnario kremzlė, klinikinė ir funkcinė būklė labai pagerėjo. Dauguma pacientų po kremzlės mozaikinės autologinės transplantacijos atgauna prieš pažeidimą buvusį fizinio aktyvumo lygį. Histomorfologinis persodintų transplantatų tyrimas parodė, kad visais tirtais atvejais išsilaikė hialininės kremzlės struktūra ir fibroelastinio audinio intarpai tarp transplantatų.

Patients and methods Between 1998 and 2002, a total of 85 patients underwent an osteochondral autologous transplantation (mosaicplasty) procedure for osteochondral or chondral knee joint injury. The patients were evaluated using the ICRS score, arthroscopically, histologically, with MRI and X-ray examinations. The mean duration of symptoms was 21.32 ± 5.57 months and the mean follow-up was 24.4 months (range, 12 to 60 months). The mean age of the patients during the surgery was 24.74 ± 7.20 years (range, 14 to 40 years). An independent observer performed a follow-up examination after six, twelve, twenty-four, thirty-six and forty-eight months. In 13 (15%) of 85 cases 12.4 months postoperatively, arthroscopy with biopsy for histological evaluation was carried out. A radiologist and a pathologist, both blinded to each patient’s treatment, did the radiological and histological evaluations. Results After 24.4 months all the patients showed a significant clinical improvement (p < 0.05). The cartilage Repair Society (ICRS) score, functional and objective assessment revealed 93% to have excellent or good results after mosaicplasty; 7% were fair 24.4 months (range, 12–60 months) after the operations. The ICRS evaluation showed a significant improvement after the mosaicplasty procedure 24.4 months following operations (p = 0.005). No serious complications were reported. The ICRS for macroscopic evaluation during arthroscopy 12.4 months after mosaicplasty demonstrated excellent or good repair in 11 (84%) of 13 cases. Biopsy specimens were obtained from 9 (69%) of 13 patients, and histological evaluation of repair showed good scores (according to ICRS) for most samples after mosaicplasty. A MRI evaluation demonstrated excellent or good repairs in 94% after mosaicplasty. Conclusions On an average after 24.4 months (range, 12 to 60 months) of follow-up, our clinical study has shown a significant improvement of the clinical status of the physically active patients after the mosaic type autologous osteochondral transplantation for the repair of articular cartilage defects in the knee. Histologically, the osteochondral cylinder transplants retained hyaline cartilage. Keywords: articular cartilage injury, osteochondral mosaic-like transplantation

Objective The objective of this paper is to assess the role of gender on survival rate and causes of death and organ damage in systemic lupus erythematosus (SLE) patients in China from 2009 to 2015. Methods We conducted a multicenter cohort study to analyze the differences in outcome data between male and female SLE patients. A group of 1494 SLE patients who fulfilled the 1997 American College of Rheumatology SLE classification criteria were enrolled in the Chinese Systemic Lupus Erythematosus Treatment and Research Group (CSTAR) registry from April 2009 to February 2010. All enrolled patients were followed up at least once per year from 2009 to 2015. For patients who could not attend the outpatient clinic, follow-up was conducted by telephone interview. We collected demographic data, clinical manifestations and damage scores (System Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI)). Survival rates were evaluated using the Kaplan-Meier method. Results This study included 1352 women and 142 men. The five-year survival rates were 92.0% for men and 97.6% for women. The survival rates of males were significant lower than for females ( p = 0.019). Male patients received methylprednisolone pulse therapy and cyclophosphamide significantly more than female patients ( p = 0.010). During follow-up, 12 male patients and 66 female patients died. The most common cause of death was infection (41.7%) for men and active SLE disease (27.3%) for women. At the end of the study, the major accumulated organ damages included renal (8.5%) and musculoskeletal (7.7%), and nervous system (5.6%) for men and renal (8.8%) and musculoskeletal (6.7%) for women. There were no significant differences in SDI scores between the two groups at baseline and at the end of the study. Conclusions Male SLE patients had lower survival rates than female patients. Male patients received more methylprednisolone pulse and cyclophosphamide therapy. The most common causes of death were infection for male patients and active SLE disease for female patients. The major accumulated organ damages were renal, musculoskeletal, and nervous system both for male and female SLE patients in China.

Aims and Objectives: Full thickness cartilage defects may be devastating for the patients. Even though, the surgical options have improved, only limited information for returning to sports. Aim of this study was therefore to compare the functional outcome and the return to sports rate of patients following cartilage regenerative treatment at a minimum follow up of 12 months. Materials and Methods: A total of 50 Patients (32 male, 18 female) undergoing cartilage regeneration using a Matrix-associated chondrocyte transplantation (MACT, Novocart, TETEC, Aesculap) (27 femorotibial, 23 patellofemoral) were evaluated at a minimum follow-up of 12 months. Follow-up was performed using a multifactorial functional analysis including isokinetic strength measurements (BTE-primus), proprioceptive tests (MTF tests), a tapping test and a 3d-motion analysis (myomotion, Noraxon) during single leg squats, bilateral drop jumps and single leg hop tests. Agility was assessed using a lateral speedchase (Globalspeed, Hemsbach). Clinical results were recorded using Tegner and Lysholm score. Results: Patients showed a Lysholm score of 86,3 +/-10,3 and 84,0 +/-13,9 for male and female, respectively. The tegner score was significantly reduced when compared to preoperatively (male 4,72 +/-1,6, female 4,75 +/-1,5). Thigh circumference was reduced by an average of 3,6 cm for male and 4,4 cm for female patients. The tapping test revealed no differences between male and female patients providing a leg symmetry index (LSI) of 102,0 (+/-8,4) with an overall average frequency of 10,14 (+/-1,27). During single leg squat male patients had a significantly lower knee flexion of 55,8 (+/-8,5) of the postoperative leg compared to the non-injured leg (62,2 +/-8,2) whereas the knee abduction was -6.8 (+/-15,1) and -11,8 -11,82 (+/-16,6) for the postoperatively and non-injured leg, respectively. Evaluating the single leg hop, the LSI of distance values was 90,8 (+/-11,9) and for height values 84,0 (+/-16,0) for the male patients. There was a trend towards reduced ROM with regard to knee flexion of the injured leg to the non-injured. Cutting time during lateral speedchase showed a LSI of 98,29 (+/-13,8) and 99,44 (+/-8,2) for male and female patients, respectively. Conclusion: This prospective analysis of patients following cartilage regeneration implicates that the use of a multifactorial “return-to-sports” analysis 12 months postoperatively provides a good correlation to the clinical outcome and scores. At this FU point, Patients following MACT show knee joint function that is close to normal.

Introduction Autologous osteochondral transplantation (AOT) is a treatment for osteochondral lesions with known concerns, including histological degradation of the graft and poor cartilage integration. Platelet-rich plasma (PRP) and hyaluronic acid (HA) have been described has having the potential to improve results. The aim of this study was to evaluate the effect of PRP and HA on AOT in a rabbit model. Methods Thirty-six rabbits underwent bilateral knee AOT treated with either the biological adjunct (PRP, n = 12; HA, n = 12; PRP + HA, n = 12) or saline (control). PRP and HA were administered as an intra-articular injection. The rabbits were euthanized at 3, 6, or 12 weeks postoperatively. The graft sections were assessed using the modified International Cartilage Repair Society (ICRS) scoring system. The results from the PRP alone group is from previously published data. Results The mean modified ICRS histological score for the PRP-treated group was higher than its control ( P = 0.002). The mean modified ICRS histological score for the HA-treated group showed no difference compared with its control ( P = 0.142). The mean modified ICRS histological score for the PRP + HA–treated group was higher than its control ( P = 0.006). There was no difference between the mean modified ICRS scores of the PRP- and the PRP + HA–treated grafts ( P = 0.445). Conclusion PRP may decrease graft degradation and improve chondral integration in an animal model. In this model, the addition of HA was not synergistic for the parameters assessed. Level of Evidence. Basic science, Level V. Clinical Relevance. PRP can be used as an adjunct to AOT, which may decrease graft degeneration and improve clinical outcomes. HA may not influence AOT.

Objective: The objective of this study was to analyze demographics, management pattern, and clinical outcomes in patients with organophosphorus poisoning. Methods: In this subgroup analysis of retrospective data of patients admitted in intensive care unit (ICU) with a diagnosis of acute organophosphorus poisoning, demographic details, pattern of use of medicines, dose of atropine and pralidoxime (PRAM), duration of ICU stay, and clinical outcomes were analyzed. Results: A total of 92 patients with organophosphorus poisoning (mean age 34.7 years; male 69 [75%]) were included. The age of male patients was more than female patients (36.2 vs. 30.0 years; p=0.047). Atropine and PRAM were given to all patients. Ondansetron was used in all patients, whereas ranitidine was used in 91 (98.9%) patients. The mean total dose of atropine in male and female population was 99.5 mg and 89.0 mg, respectively (p=0.298). The mean total dose of PRAM in male and female population was 12.2 mg and 12.0 mg, respectively (p=0.772). There was no difference in the mean (standard deviation) duration of stay in ICU between male patients and female patients (7.6 [4.5] vs. 6.4 [3.9] days; p=0.249). A total of 61 (66.3%) patients were transferred to the ward, whereas 30 (32.6%) died. Conclusion: Atropine and PRAM are the primary drugs for the treatment of organophosphorus poisoning. Ondansetron and ranitidine are useful drugs for the treatment of vomiting and gastric irritation, respectively, in these patients.

Background: The effect of patient age or sex on outcomes after osteochondral allograft transplantation (OCA) has not been assessed. Purpose: To determine clinical outcomes for male and female patients aged ≥40 years undergoing OCA compared with a group of patients aged <40 years. Study Design: Cohort study; Level of evidence, 3. Methods: A review of prospectively collected data of consecutive patients who underwent OCA by a single surgeon with a minimum follow-up of 2 years was conducted. The reoperation rate, failure rate, and patient-reported outcome scores were reviewed. All outcomes were compared between patients aged <40 or ≥40 years, with subgroup analyses conducted based on patient sex. Failure was defined as revision OCA, conversion to knee arthroplasty, or gross appearance of graft failure at second-look arthroscopic surgery. Descriptive statistics, Fisher exact or chi-square testing, and Mann-Whitney U testing were performed, with P < .05 set as significant. Results: A total of 170 patients (of 212 eligible patients; 80.2% follow-up) who underwent OCA with a mean follow-up of 5.0 ± 2.7 years (range, 2.0-15.1 years) were included, with 115 patients aged <40 years (mean age, 27.6 ± 7.3 years; 58 male, 57 female) and 55 patients aged ≥40 years (mean age, 44.9 ± 4.0 years; 33 male, 22 female). There were no differences in the number of pre-OCA procedures between the groups ( P = .085). There were no differences in the reoperation rate (<40 years: 38%; ≥40 years: 36%; P = .867), time to reoperation (<40 years: 2.12 ± 1.90 years; ≥40 years: 3.43 ± 3.43 years; P = .126), or failure rate (<40 years: 13%; ≥40 years: 16%; P = .639) between the older and younger groups. Patients in both groups demonstrated significant improvement in Lysholm (both: P < .001), International Knee Documentation Committee (IKDC) (both: P < .001), Knee Injury and Osteoarthritis Outcome Score (KOOS) (both: P < .001), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) (both: P < .001), and Short Form–12 (SF-12) physical (both: P < .001) scores compared with preoperative values. Patients aged ≥40 years demonstrated significantly higher KOOS symptom ( P = .015) subscores compared with patients aged <40 years. There were no significant differences in the number of complications, outcome scores, or time to failure between the sexes. In patients aged <40 years, female patients experienced failure significantly more quickly than male patients ( P = .039). In contrast, in patients aged ≥40 years, male patients experienced failure significantly more quickly than female patients ( P = .046). Conclusion: This study provides evidence that OCA is a safe and reliable treatment option for osteochondral defects in patients aged ≥40 years. Male and female patients had similar outcomes. Patients aged <40 years demonstrated lower KOOS symptom subscores postoperatively compared with older patients, potentially attributable to higher expectations of return to function postoperatively as compared with older patients.

Introduction: The optimal treatment of an osteochondral patellar lesion remains controversial. Autologous osteochondral transplantation shows promising outcomes, although there is scarce evidence. Objective: Present a 10-year follow-up experience and outcomes of patients with a full-thickness defect of the patella at our institution. Methods: Retrospective analysis of all the patients treated with autologous osteochondral transplantation between 2007-2018 for a patellar osteochondral lesion (ICRS IV). We analyzed the WOMAC score and demographic characteristics with IBM SPSS (IBM Corp. Released 2017. IBM SPSS Statistics for Windows, Version 25.0. Armonk, NY: IBM Corp). Results: A total of 14 patients (age range 15-49 years) were included. The right knee, medial facet, and the medial patellofemoral ligament (69%) were the anatomical sections and associated injuries most frequently encountered. The mean lesion area was of 1.32 cm2, with 55% requiring 2 autologous osteochondral transplantations (size range 8-10 mm2). The mean WOMAC score was 97% (91% Pain, 87% Stiffness, 95% Physical function), with a tendency of an inverse relation with age (p=0.227). Conclusion: Full-thickness defects of patellar cartilage are seen frequently in young patients. These lesions affect their quality of life, sports activity, and physical functionality. However, our outcomes at medium-term follow-up (Mean WOMAC 97), despite it is a small cohort, are promising. Long-term follow-up studies on this topic are encouraged to suggest an optimal treatment based on high-quality evidence.
