The Role of Tibial Osteotomy in the Outcome of Meniscus Allograft Transplantation

Objectives: Meniscal allograft transplantation (MAT) is indicated to relieve pain and improve function and hopefully to delay the onset of osteoarthritis in patients with meniscus deficiency. The purpose of this study was to compare the effect of perioperative cartilage status on survivorship and whether this is influenced by a concurrent tibial osteotomy. Methods: We reviewed a consecutive series of 45 MATs in 42 patients with a minimum post-surgical time of four years. Patients were divided into two groups using the Outerbridge Cartilage Score (OSC) to group 1 (minimal cartilage damage of grade 0-2) and group 2 (severe cartilage damage of grade 3-4). Pre- and post-operative outcome scores were collected using the Lysholm, Tegner, Oxford Knee Score (OKS) and International Knee Documentation Committee (IKDC) subjective knee form. Survival end points were transplant removal and knee arthroplasty. Results: The mean post-surgical follow-up for patients in group 1 (n=14, age 32.0 +/- 9.8) and group 2 (n=31, age 36.2 +/- 10) was 10.6 years (SD +/-3.35) and 7.1 (SD+/-3.34) respectively. There was no significant difference in the mean age between the two groups (p-value 0.221, CI -2.62 to 11). Patients in group 1 demonstrated no failures of the MAT over the time frame evaluated. Group 2 (n=31) had a 74.2% survival of MATs. The clinical outcomes improved in all groups with no significant difference between group 1 and group 2. Those patients in the osteotomy group did not have a statistically significant different survival (Mantel-cox test p-value of 0.922) or clinical outcome. Conclusion: Patient with minimal cartilage status have improved MAT survivorship but both groups benefit clinically. Tibial osteotomy, when indicated, does not influence the outcome of MAT.

Objectives: To compare nasal and upper airway dimensions in patients with cleft lip and palate (CLP) who underwent nasoalveolar molding (NAM) with those without NAM during infancy using acoustic pharyngometry and rhinometry. Materials and Methods: Eccovision acoustic pharyngometry and rhinometry (Sleep Group Solutions) was used for assessment of mean area and volume of nasal and upper airway in patients with complete unilateral CLP (age range 16-21 years) treated with NAM (group 1, n = 19) versus without NAM (group 2, n = 22). Results: The mean nasal cross-sectional areas and volume were higher in group 1 compared to group 2 on both cleft ( P value <.001) and noncleft side ( P value >.05). The mean area and volume of upper airway were also significantly higher in group 1 compared to group 2 ( P value <.05). Conclusions: Nasoalveolar molding being one of the first interventions in chronology of treatment of patients with CLP, its long-term outcome on nasal and upper airway patency needs to be ascertained. The results of the present study show that the patients with CLP who have undergone NAM during infancy have better improvement in nasal and upper airway patency compared with those who had not undergone NAM procedure. The basic advantages of being noninvasive, nonionizing and providing dynamic assessment of nasal and upper airway patency make acoustic pharyngometry and rhinometry a diagnostic tool of choice to be used in patients with CLP.

Background: Knot-tying suture-bridge (SB) rotator cuff repair may compromise the vascularity of the repaired tendon, causing tendon strangulation and medial repair failure. The knotless SB repair technique has been proposed to overcome this possibility and decrease retear rates. Purpose: To compare clinical and structural outcomes and retear patterns between the knot-tying and knotless SB techniques. We hypothesized that the knotless technique would result in lower retear rates owing to the preservation of intratendinous vascularity. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: A total of 104 patients with full-thickness rotator cuff tears were randomly and prospectively allocated to undergo knot-tying (group 1) or knotless (group 2) SB repair. Clinical outcome measures included range of motion, the visual analog scale (VAS) for pain, and the Constant score for function. Repair integrity was evaluated on magnetic resonance imaging scans using the Sugaya classification. Retears were also classified according to their pattern as type 1 (lateral) or type 2 (medial). Results: Overall, 88 patients (group 1: n = 42 [mean ± SD age, 54.3 ± 9.8 years]; group 2: n = 46 [mean ± SD age, 55.8 ± 8.2 years]) were included in the final analysis. The mean ± SD follow-up period was 25.4 ± 8.3 and 23.3 ± 7.2 months for groups 1 and 2, respectively. From preoperatively to postoperatively, the mean VAS pain score improved significantly in both groups (group 1: from 7.4 ± 1.7 to 1.0 ± 1.7; group 2: from 7.1 ± 1.9 to 1.3 ± 2.0; P < .0001 for both), as did the mean ± SD Constant score (group 1: from 51.7 ± 13.4 to 86.0 ± 11.5; group 2: from 49.4 ± 18.4 to 87.2 ± 14.8; P < .0001 for both). There was no significant difference between the groups for the postoperative VAS or Constant score. The retear rate was not significantly different between the groups (19.0% [8/42] in group 1 and 28.3% [13/46] in group 2; P > .05). There was a significant difference in the type 2 failure rate (75.0% [6/8] in group 1 and 23.1% [3/13] in group 2; P = .03). Conclusion: Both techniques showed excellent improvement and comparable clinical outcomes, and there was no significant difference in retear rates. Consistent with previously published data, the type 2 failure rate was significantly higher with the knot-tying technique. Registration: NCT03982108 ( ClinicalTrials.gov identifier).

Abstract Purpose to compare between recurrence incidence after primary pterygium excision when using preoperative subconjunctival injection of Bevacizumab (Avastin) and using it as a postoperative eye drops. Methods thirty two eyes of thirty patients (two patients had bilateral pterygium) with primary pterygia were clinically examined, classified into 3 groups and operated by simple excision with bare sclera technique. Group 1 included 10 patients received Bevacizumab (Avastin) in the form of eye drops (10 mg/ml) 3 times daily for 6 days postoperative. Group 2 included 10 patients received preoperative Bevacizumab in the form of subconjunctival injection (1.25 mg/0.05ml) single dose 1 week preoperative. Group 3 included 10 patients (12 eyes) 2 patients with bilateral Pterygium didn’t receive any form of Bevacizumab. Postoperative follow up was done clinically and by serial photography at 1 week, 1 month, 3 months and 6 months searching for signs of recurrence and/or complications. Results The results showed different grades of recurrence in 18 eyes of 32.True recurrence was seen in 7 patients of 18 (1 patient in group 1, 2 in group 2 and 4 in group3).Recurrence grades in group 1and 2 who used the Bevacizumab (20%grade II, 50% grade III, and 30% grade IV). Recurrence could be predicted by 100% depending on fibrovascular tissue appearing in the surgical bed at 3 months postoperative (P value 0.038).Preoperative fleshy pterygium has high statistical significance in realation to recurrence(P value = 0.006).Patient’s sex, residence and occupation had no statistically significant value in the process of recurrence (P value > 0.05). Patients with recurrent Pterygia (in group 1&2) had statistically significant changes in the corneal K- readings at 3 months and 6 months.No significant difference in the limbal or central corneal thickness in the operated eye and the other eye (Pvalue > 0.05). Conclusion Bevacizumab (Avastin) is a well tolerated drug with multiple drug delivery methods.The eye drops give better results than the subconjunctival injection.Appearance of fibrovascular tissue in the surgical bed at 3 months predict the recurrence by 100%. Preoperative fleshy pterygia will mostly recur again whatever Bevacizumab form was used .The corneal thickness by anterior segment OCT has no role in prediction or detection of early pterygium recurrence.

Arthrofibrotic stiffness of the knee joint has been recognized as a highly debilitating complication after complex knee reconstruction. The clinical impact of arthroscopic revision surgery was evaluated for patients with knee arthrofibrosis following total knee arthroplasty (TKA) and after joint preserving procedures. Hypothesis: Arthroscopic revision surgery is associated with functional benefits in both groups. We retrospectively reviewed a consecutive series of adult patients (#CHR: greaterlike#18 years) at a single institution who underwent arthroscopic revision for knee stiffness. Minimum follow-up: 24 months. The analysis included demographic, surgical and histological data. The following outcome parameters were evaluated: pain (Visual Analog Scale, VAS); objective score systems (Oxford Knee Score) and patient activity (Tegner Activity Scale (TAS), Univ. of California Activity Scale (UCLA)). Furthermore, range of motion (ROM) was compared pre-, intra- and postoperatively. Finally, we compared body mass index (BMI) and quality of life (EQ-5D) changes. We identified a total of 57 patients who underwent arthroscopic adhesiolysis for knee arthrofibrosis: 45 after TKA (Group 1) and 12 patients with ligament reconstruction (Group 2). The patient cohort included thirty (43.5%) males and thirty-six (56.5%) females. Mean age was 69 (SD 10.6) years in the TKA group and 41 (SD 12.7) years in group 2 (p=0.01). Mean length of stay (LOS) was 4.6 days in Group 1 and 2.8 days in Group 2. Pain levels (VAS) were reduced significantly in both groups (p=0.004); from 7.5 to 4.8 in Group 1 and from 7.8 to 2.9 (Group 2). In terms of sports activity, 26 patients (37.7%) reported an improved sports activity (UCLA score). The TAS improved from 2.58 to 4.08 in Group 2. The Oxford Knee Score improved from 23.5 to 27.2 in Group 1 and from 16.5 to 36.3 in Group 2. No reduction in BMI was observed. However, quality of life (EQ-5D) improved from 47.6 to 51.9 Group 1; and from 52.9 to 71.7 in Group 2. Arthroscopic revision of the stiff knee may offer clinical benefits in terms of significant pain reduction, an improved level of activity and quality of life in stiffness following both TKA and joint preserving surgical reconstruction.

BACKGROUD: Chronic liver diseases in childhood often cause undernutrition and growth failure. To our knowledge, growth parameters in infants with neonatal cholestasis are not available AIM: To evaluate the nutritional status and growth pattern in infants with intrahepatic cholestasis and extrahepatic cholestasis. PATIENTS AND METHODS: One hundred forty-four patients with neonatal cholestasis were followed up at the Pediatric Gastroenterology Service of the Teaching Hospital, State University of Campinas, Campinas, SP, Brazil, in a 23-year period, from 1980 to 2003. The records of these patients were reviewed and patients were classified into two groups, according to their anatomical diagnosis: patients with intrahepatic cholestasis - group 1, and patients with extrahepatic cholestasis - group 2. Records of weight and height measurements were collected at 4 age stages of growth, in the first year of life: 1) from the time of the first medical visit to the age of 4 months (T1); 2) from the 5th to the 7th month (T2); 3) from the 8th to the 10th month (T3); and 4) from the 11th to the 13th month (T4). The weight-by-age and height-by-age Z-scores were calculated for each patient at each stage. In order for the patient to be included in the study it was necessary to have the weight and/or height measurements at the 4 stages. Analyses of variance and Tukey's tests were used for statistical analysis. Repeated measurement analyses of variance of the weight-by-age Z-score were performed in a 60-patient sample, including 29 patients from group 1 and 31 patients from group 2. The height-by-age data of 33 patients were recorded, 15 from group 1 and 18 from group 2 RESULTS: The mean weight-by-age Z-scores of group 1 patients at the 4 age stages were: T1=-1.54; T2=-1.40; T3=-0.94; T4=-0.78. There was a significant difference between T2 X T3 and T1 X T4. The weight-by-age Z-scores for group 2 patients were :T1=-1.04; T2=-1.67; T3=-1.93 and T4=-1.77, with a significant difference between T1 X T2 and T1 X T4. The mean weight-by-age Z-scores also showed a significant difference between group 1 and group 2 at stages T3 and T4. The mean height-by-age Z-scores at the four stages in group 1 were: T1=-1.27; T2=-1.16; T3=-0.92 and T4=-0.22, with a significant difference between T3XT4 and T1XT4. The scores for group 2 patients were: T1=-0.93; T2=-1.89; T3=-2.26 and T4=-2.03, with a significant difference between T1XT2 and T1XT4. The mean height-by-age Z-scores also showed a significant difference between group 1 and group 2 at T3 and T4 CONCLUSION: The weight and height differences between the groups became significant from the 3rd measurement onward, with the most substantial deficit found in the extrahepatic group. In this group, there is evidence that the onset of weight and height deficit occurs between the first and second evaluation stages.

Aim: To compare surgical parameters and visual outcomes of coaxial microincision cataract surgery (MICS) with standard phacoemulsification. Methods: A prospective randomized study was conducted on 60 eyes of 60 patients with age-related uncomplicated cataract who underwent: standard phacoemulsification surgery (30 eyes) i.e., Group 1, or coaxial MICS (30 eyes) i.e., Group 2. Intraoperative parameters were mean effective phacoemulsification power (EPP), effective phacoemulsification time (EPT), and total volume of balanced salt solution (BSS) used. Best-corrected visual acuity (BCVA) and surgically induced astigmatism (SIA) were evaluated pre- and postoperatively. Results: Mean BCVA at 6 weeks was 0.04 ± 0.07 in Group 1 and 0.05 ± 0.08 in Group 2. No significant difference was observed in SIA between the two groups. Mean EPT was 29.80 ± 3.67 seconds in Group 1 and 31.93 ± 4.08 seconds in Group 2. The mean total EPP in Group 1 was 35.77 ± 5.17%, whereas it was 33.70 ± 3.05% in Group 2. There was a significant statistical difference between mean EPP and EPT in the two groups. Mean total BSS volume used in Group 1 was 128.83 ± 19.81 ml, whereas it was 139.33 ± 13.57 ml in Group 2. Conclusion: Although EPT and BSS volume used were significantly higher in coaxial MICS, the postoperative results of the two techniques were comparable.

Abstract Purpose: To compare the effect of intravitreal ranibizumab (IVR) or intravitreal dexamethasone implants (IVD) on regression of hyperreflective dots (HRDs) on optical coherence tomography (OCT) B-scan in patients with branch retinal vein occlusion (BRVO). Methods: 37 eyes of 37 patients with cystoid macular edema who received IVR or IVD and followed up for at least 12 months were included in this study. The patients were divided into three groups according to intravitreal treatment. Group 1 consisted of 12 eyes who received only IVD, group 2 consisted of 10 eyes who received only IVR on a pro re nata and group 3 consisted of 15 eyes who received both IVD and IVR. OCT parameters (CMT, number of HRDs, status of external limiting membrane (ELM) and ellipsoid zone (EZ)) and best-corrected visual acuity (BCVA) were compared between the groups over the follow-up time. HRDs were categorized as HRD in inner retinal layers (from the internal limiting membrane to the inner nuclear layer) or HRD in outer retinal layers (from the outer plexiform layer to the outer border of the photoreceptor layer).Results: There was no significant difference between groups in terms of BCVA, CMT, HRDs in the inner and the outer retinal layers at baseline visit. (p˃0.05 for all) Comparing the baseline values in all groups, a significant decrease was observed in CMT in the first year. (For group 1; p=0.013, group 2; p=0.010; group 3, p<0.001) The BCVA was significantly increased after 1 year in all groups. (p=0.001, p=0.006, p<0.001) The mean number of HRDs in inner and outer retinal layers were significantly decreased in group 1 and group 3. (For group 1; p<0.001, p=0.001, for group 3; p<0.001, p<0.001) However, there was no significant difference in terms of the mean number of HRDs in inner and outer retinal layers for group 2. (p=0.134, p=0.477) At the first year, the number of HRDs in inner and outer retinal layers was significantly lower in group 1 and group 3 than group 2. (For inner HRDs; group 1 vs. group 2 p=0.007, group 2 vs. group 3 p<0.001. For outer HRDs group 1 vs. group 2 p<0.001, group 2 vs. group 3 p<0.001.) The BCVA was higher in group 3 than group 2 at 1year. (p=0.048). There was no significant difference in terms of post-treatment CMT and the number of HRDs between group 1 and group3 in posthoc tests (p=0.621, p=0.876, and p=0.632).Conclusion: The reduction in HRDs at 12 months and better BCVA after IVD intimates that the HRDs should be considered as inflammatory markers in the follow-up of CME in BRVO. Thus, IVD injection could be more appropriate for patients with higher HRDs after BRVO.

Background: Different methods are found for mesh fixation in inguinal hernioplasty both open and laparoscopic. In open technique, sutures have been the method of choice for their reduced costs and surgeons’ habits. Whether absorbable instead of non-absorbable sutures can be used still a matter of debate in view of hernia recurrence and post-operative complications.Methods: This is a prospective done on 158 male patients with uncomplicated unilateral inguinal hernias. Two groups of 69 patients were evaluated after periods up to 1 year after open hernioplasty by using delayed absorbable sutures in one group (group 1) and non-absorbable sutures in the other group (group 2) for fixation of mesh.Results: In spite of a noticeable reduction in complication in the group 1 in term of number and percentage when compared with group 2 mainly chronic pain, there is no significant difference (p value>0.05). However, these results are associated with zero recurrence in both groups during a period of one year follow up.Conclusions: Delayed absorbable sutures are good alternative of non-absorbable sutures in open mesh hernia repair associated with less complications and almost no increase in chance of recurrence.

Background: Flexor tendon rupture is a major complication after volar locking plating for distal radius fracture (DRF). Few studies have investigated changes in the rate of postoperative flexor tendon rupture in patients with DRFs. The present study aimed to investigate the changes in the rate of postoperative flexor tendon rupture and to assess plate placement and reduction positions. Methods: We retrospectively reviewed patients in whom more than 24 months had passed since DRF surgery. The patients were interviewed by telephone. Forty-nine patients (50 fractures; 2007–2009) from institution A were included in group 1 and 81 patients (84 fractures; 2013–2016) from institution B were included in group 2. The DRF surgery method was similar between the two groups. The rate of flexor tendon rupture, Soong classification grade, and radiological index (i.e., volar tilt [VT], radial inclination [RI], and ulnar variance [UV]) were statistically investigated in both groups. Results: Patient epidemiology was not significantly different between the two groups. The flexor tendon rupture rates were 2% and 0% in groups 1 and 2, respectively, without a significant difference. With regard to the Soong grade, 44 fractures were grade 2 and 6 were grade 1 in group 1, whereas 18 were grade 2, 38 were grade 1, and 28 were grade 0 in group 2, with a significant difference (p < 0.05). With regard to the radiological index, the mean VT values were 5° and 11° in groups 1 and 2, respectively, with a significant difference (p < 0.05). However, RI and UV showed no significant difference. Conclusions: Plate placement and reduction positions, which are risk factors for flexor tendon ruptures after DRFs, have improved recently when compared with previous findings. With these changes, the rate of flexor tendon rupture is presumed to have decreased.
