Purpose. To evaluate the outcomes of femtosecond laser-assisted implantation of a 355-degree intracorneal ring (ICR) (Keraring) in patients with keratoconus in the three-year follow-up. Setting. Future Femtolaser Center, Sohag, Egypt. Design. Prospective interventional case series. Patients and Methods. A prospective case series of 38 eyes of 26 patients with keratoconus had implantation of the 355-degree ICR keraring after tunnel creation with a femtosecond laser. The uncorrected visual acuities (UCVA) and best-corrected visual acuities (BCVA), sphere, cylinder, and manifest refraction spherical equivalent (SE), and mean keratometry (K), K max, and K min were evaluated preoperatively and 3, 6, 12, 24, and 36 months postoperatively, and all complications were reported. Results. 38 eyes of 26 patients with mean age 25.92 ± 5.44 years were enrolled in the study, 11 were males (42.3%). The mean UCVA improved from 0.93 ± 0.21 to 0.63 ± 0.21 logMAR (P≤0.001) and the mean BCVA from 0.67 ± 0.22 to 0.43 ± 0.26 logMAR (P<0.001). The mean sphere, cylinder, and spherical equivalent have been changed dramatically from preoperative to 3 month postoperative, which is statistically significant (P≤0.001), and the changes between 1 and 2 years and 2 and 3 years are also considerable and statistically significant; the K max and K min and K mean improved and the changes were statistically significant (P≤0.001), and the changes between one, two, and three years were also statistically significant. The safety and efficacy indices were changed through the three-year follow-up. The complications were corneal neovascularization (36.84%), corneal melting (26.3%), and ring extrusion (31.5%) at the end of the study. Conclusions. Implantation of a 355-degree intracorneal keraring using femtosecond laser improved the visual, refractive, and topographic parameters in keratoconus patients, with a high rate of ICR extrusion and instability. The study has been registered for the Pan African Clinical Trial Registry (http://www.pactr.org) database within No: PACTR201810796878908 on 29 October 2018.

Medial Release

Background Medial subluxation of the patella is a rare, disabling condition that has iatrogenic and traumatic causation. To date, only open reconstructions have been reported for operative treatment of this condition, but these procedures have a high rate of complications, revisions, and subsequent surgery. This is the first study to present the results of arthroscopic medial retinacular release for treatment of this problem. Hypothesis Arthroscopic release will alleviate painful medial patellar subluxation. Study Design Case series; Level of evidence, 4. Methods Nine knees (7 patients) with painful, recurrent medial subluxation of the patella that occurred spontaneously (2 knees) or after a lateral release (5 knees) or an injury (2 knees) were treated with an arthroscopic medial retinacular release. The retinaculum was released 2 cm medial to the superior pole of the patella down to the anteromedial portal. At a mean follow-up of 2.7 years (range, 1-8 years), all knees were evaluated, and the results were graded according to the Merchant and Mercer rating scale. Results The mean age of the patients was 25 years (range, 15-38 years), and the mean duration of the subluxations before surgery was 28 months (range, 6-48 months). In all 7 patients (9 knees), the medial release relieved their medial subluxation and knee pain, and there were 6 excellent and 3 good results. There were no complications or further realignment surgery needed after this procedure. Conclusion An arthroscopic medial retinacular release will successfully treat painful medial subluxation of the patella.

Abstract Background Isolated scaphotrapeziotrapezoid (STT) osteoarthritis (OA) mainly develops in women over 50 years of age in a bilateral manner. Many surgical treatments are available, including distal scaphoid resection with or without interposition, trapeziectomy, and STT arthrodesis. However, there is a controversy about which procedure is the most effective. Purposes The purpose of this study was to report the outcomes of the Pyrocardan implant for treating STT isolated OA at a mean follow-up of 5 years. Patients and Methods Consecutive patients who underwent STT arthroplasty using the Pyrocardan were reviewed retrospectively by an independent examiner who performed a clinical and radiological evaluation. Results The mean follow-up time was 5 years (range 3–8 years). Thirteen patients (76%) were followed for more than 5 years. Between the preoperative assessment and the last follow-up, pain levels decreased significantly. There was no significant difference in the mean Kapandji opposition score. Grip and pinch strengths were 88 and 91% of the contralateral side. The active range of motion in flexion–extension and radioulnar deviation was not significantly different to the contralateral side (119° vs. 121° and 58° vs. 52°, p > 0.1). Functional scores were improved significantly. No identifiable differences were found in the radioscaphoid, capitolunate, and scapholunate angles before and after surgery. In three cases, the preoperative dorsal intercalated scapholunate instability (DISI) failed to be corrected. In one case, DISI appeared after the procedure. There was one asymptomatic dislocation of the implant. Calcification around the trapezium and/or distal scaphoid was found in four cases. The survival rate of the implant without reoperation was 95%. Conclusions In the medium term, Pyrocardan implant is an effective treatment for STT OA as it reduces pain, increases grip strength, and maintains wrist mobility. This is consistent with the results of other published case series using pyrocarbon implants. It provides a high rate of patient satisfaction. Nevertheless, the surgical procedure must be done carefully to avoid STT ligament damage, periarticular calcifications, or dislocation.

Abstract Aim Presentation of our data on Vacuum-Assisted Wound Closure and Permanent Onlay Mesh-Mediated Fascial Traction (VAWCPOM) in combination with Botulinum Toxin A (BTX-A) injection in the lateral abdominal wall as a treatment of the open abdomen (OA). Material and Methods This is a retrospective case series including patients treated for OA from January 2017 till March 2021 with VAWCPOM and BTX-A. Patient records were collected from medical charts, incl. age, sex, body mass index (BMI), comorbidity, initial fascial defect size, time until fascial closure, complications and, when available, outpatient follow-up. Results A total of 33 patients with OA were included. The mean age was 62,5 years, male/female ratio was 15:18, with a mean BMI of 35,4 kg/m2. The mean width of the fascial defect was 13,5 cm (5 - 25cm). The rate of fascial closure was 96,9%, achieved within a mean of 22,7 days. Fascial closure was not attainable in one patient who developed enterocutaneous fistula under treatment. 22 patients experienced in-hospital complications. Short-term follow-up was conducted in 22 patients, with hernia recurrences in three. Conclusions Treatment of OA remains a surgical challenge. This case series shows promising results with a high rate of fascial closure using a combination of VAWCPOM and BTX-A and an acceptable rate of postoperative complications in this severely challenging patient group. The rate of primary closure indicates that this may be the future management of open abdomen.

Abstract Objective The purpose of the present prospective, case-series study was to report implant survival rate and marginal bone remodeling expected 5 years after loading using dental implants placed in daily practice. Materials and Methods This research was designed as an open-cohort, prospective, case-series evaluation. Any partially or completely edentulous patient, scheduled to receive at least one bone level implant, was considered eligible for this study. Primary outcome measurements were: implant and prosthetic cumulative survival rate and any complications experienced up to the 5-year follow-up. Secondary outcome measures were: thickness of gingival biotype, implant insertion torque, implant stability quotient, and marginal bone loss (MBL). Results Ninety consecutive patients (34 males and 56 females, aged between 24 and 81 years old [mean: 53.2 ± 15.4]) with 243 inserted implants were followed for at least 5 years after loading (mean: 65.4 ± 3.1 months; range from 60 to 72). At the 1-year follow-up, no drop-outs were recorded, but 17 patients (18.9%) with 18 restorations (12.6%) delivered on 34 implants (14%) were lost at the 5-year examination. At the 5-year follow-up examination, six implants lost osseointegration (97.5%). In the same period, four prostheses failed (97.2%). Five complications were reported in five different patients (prosthetic success rate was 96.5%, at patient level). Five years after loading, the mean MBL was 0.41 ± 0.30 mm. The difference from the 1-year data was 0.04 ± 0.19 mm. A statistically significant higher MBL was found for smokers, and patients with thin gingival biotype. The mean implant insertion torque was 42.9 ± 4.8 Ncm (range from 15 to 45 Ncm). Two-hundred and three implants (83.5%) were inserted with an insertion torque ≥35 and ≤45 Ncm. Conclusions High implant survival and success rate could be expected with stable marginal bone remodeling up to 5 years after loading. Smoking and thin tissue biotype were the most important variabilities associated with higher MBL. Further research studies are needed to confirm these results.

Background In a previously published report of the authors’ arthroscopic technique of operative management of recalcitrant lateral epicondylitis, they demonstrated short-term success with the procedure in their patients. Hypothesis Arthroscopic management of patients with lateral epicondylitis can produce clinical improvement and have successful long-term outcomes. Study Design Case series; Level of evidence, 4. Methods Forty patients (42 elbows) with lateral epicondylitis who had not responded to nonoperative management were treated with arthroscopic resection of pathologic tissue. Thirty of these patients (30 elbows) were located for extended follow-up. At a mean follow-up of 130 months (range, 106–173 months), patients were asked to use a numeric scale to rate their elbow pain from 0 (no pain) to 10 (severe pain). Patients were also asked to rate their elbows according to the functional portion of the Mayo Clinic Elbow Performance Index. Results The mean pain score at rest was 0; with activities of daily living, 1.0; and with work or sports, 1.9. The mean functional score was 11.7 out of a possible 12 points. No patient required further surgery or repeat injections after surgery. One patient continued to wear a counterforce brace with heavy activities. Twenty-three patients (77%) stated they were “much better,” 6 patients (20%) stated they were “better,” and 1 patient (3%) stated he was the same. Twenty-six patients (87%) were satisfied, and 28 patients (93%) stated they would have the surgery again if needed. Conclusion Arthroscopic removal of pathologic tendinosis tissue is a reliable treatment for recalcitrant lateral epicondylitis. The early high rate of success in patients was maintained at long-term follow-up.

Abstract Background Stiff knees, like completely ankylosed or arthrodesed knees, can be painless. Total knee arthroplasty (TKA) for these painless, stiff knees is technically demanding. However, it can correct the alignment and advance the range of motion to improve quality of life. So, we reviewed the preoperative and postoperative results of functional and pain scores, range of motion (ROM) and complications in painless, stiff knees treated by TKA. Methods Fifteen painless, stiff knees underwent TKA from January 1998 to January 2017. The mean follow-up period was 15.4 (2.4–22.2) years. All the knees were completely ankylosed or arthrodesed. Clinical outcome and complications were evaluated using medical record review, serial plan radiography, ROM assessment, Knee Society score (KSS), Knee Society function score (FS), and a visual analog scale for pain (VAS). Results All patients were satisfied with their operated knees. Mean KSS and FS scores were improved from 36 and 50.9 to 76.9 and 67.2, respectively (P < 0.001 and P = 0.01). The mean ROM increased from 0º preoperatively to 77.6º (15–130) at the final follow-up (P < 0.001). The mean VAS had worsened from 0 preoperatively to 0.2 postoperatively, however it was not significant (P = 0.1). Major postoperative complications were reported in five of the knees (33.3%). Conclusions The results of TKA for painless, stiff knees were satisfactory with improved ROM and quality of life. Although some patients had mild pain and complications postoperatively, they were satisfied with the result. However, our study recommends that surgeons should consider the high rate of complications in the completely ankylosed or arthrodesed knees. Level of evidence A retrospective case series, Level IV.

Abstract Purpose To study the safety and efficacy of pterygium extended removal followed by extended conjunctival transplant for recurrent pterygia. Methods Thirty-three eyes of 33 subjects with recurrent pterygia were enrolled in this prospective case series study. Pterygium extended removal followed by extended conjunctival transplantation was done for all subjects. One surgeon (WA) performed all surgeries. All subjects completed follow-up for at least 12 months and were evaluated for recurrence and complications. Results The mean age of the participants was 41.2 ± 10.3 years (range 22–60), 7 females (21.2%). The mean duration of follow-up was 25.64 ± 9.24 months (range 12–43). Corrected distance visual acuity (decimal notation) improved from 0.69 ± 0.22 (range 0.2–1.0) at presentation to a 1-year postoperative value of 0.83 ± 0.2 (range 0.3–1.0). No recurrence was reported in all subjects throughout the follow-up period. Transient graft swelling was recorded in 14 cases (42.4%) and resolved in all cases by the first week. All patients developed variable degrees of transient postoperative diplopia that resolved completely by the first 6 weeks. Donor site granuloma developed in 4 cases (12.1%). Spontaneous resolution was observed in 3 cases, while in one case, surgical excision was performed 2 months after the procedure. Conclusions In this study of eyes with recurrent pterygia, pterygium extended removal followed by extended conjunctival transplant was found safe and effective with no recurrence and minimal postoperative complications.

Aim: the purpose of the present prospective, case series study were to report implant survival rate and marginal bone remodeling expected five years after loading using dental implants placed in in the daily practice. Material and Methods: this research was designed as an open-cohort, prospective case series study. Any completely or partially edentulous patients scheduled to receive at least one bone leve were considered eligible for this study. Primary outcomes were: cumulative implant (ISR) and prosthetic (PSR) survival rates, and any complications experienced up the five years follow-up. Secondary outcomes were: marginal bone remodeling, implant insertion torque, implant stability quotient (ISQ), and thickness of gingival biotype. Results: ninety consecutive patients (34 males and 56 females; mean age 53.2&plusmn;15.4 years; range of 24&ndash;81 years), 243 implants were placed and followed for at least five years after loading (mean of 65.4&plusmn;3.1 months; range of 60&ndash;72 months). The mean implant insertion torque was 42.9&plusmn;4.8 Ncm (range from 15 to 45 Ncm). Overall, 83.5% of the implants (n=203) were placed with an insertion torque between 35 and 45 Ncm. At the one year follow-up, no drop-outs were recorded, but 17 patients (18.9%) with 18 restorations (12.6%) delivered on 34 implants (14%) were lost at the five years examination. At the five-year examination, six implants failed in six patients, resulting in a cumulative ISR of 97.5%. At the five-year follow-up, four prostheses failed (2.8%) resulting in a cumulative PSR of 97.2%. At the five-year examination, five complications were reported by five different patients, resulting in a prosthetic success rate of 96.5%, measured at patient level. Five years after loading, mean MBL was 0.41 &plusmn; 0.30 mm (95% CI: 0.26&ndash;0.34). Difference from the one year data was 0.04 &plusmn; 0.19 mm (95% CI: 0.01&ndash;0.07). The mean ISQ value at implant placement was 71.6 &plusmn; 5.5 (range of 45&ndash;88). Six months later, the mean ISQ was 76.7 &plusmn; 4.4 (range of 66&ndash;89). The difference was statistically significant (P=0.0001). Statistically significant higher MBL was found for smokers, and patient with thin gingival biotype. Conclusions: High implant survival and success rates could be expected with stable marginal bone remodeling up to five years after loading. Smoking and thin tissue biotype were the most important variabilities associated with higher MBL. Further research are needed to confirm these results.

Abstract Purpose Current treatment of progressive early onset scoliosis involves growth-friendly instrumentation if conservative treatment fails. These implants guide growth by passive sliding or repeated lengthenings. None of these techniques provide dynamic correction after implantation. We developed the spring distraction system (SDS), by using one or multiple compressed springs positioned around a standard sliding rod, to provide active continuous distraction of the spine to stimulate growth and further correction. The purpose of this study was to determine feasibility and proof of concept of the SDS. Methods We developed a versatile, dynamic spring distraction system for patients who would benefit from active continuous distraction. This prospective case series evaluates four patients with exceptional and progressive congenital spine deformities. Results Four patients had a mean age of 6.8 years at surgery with a mean follow-up of 36 months (range 25–45). The mean progressive thoracic lordosis, which was the reason for initiating surgical treatment in two patients, changed from 32° lordosis preoperatively to 1° kyphosis post-operatively. During follow-up, this further improved to 32° thoracic kyphosis. In the two other patients, with cervicothorcacic scoliosis, the main coronal curve improved from 79° pre-operatively to 56° post-operatively and further improved to 42°. The mean T1-S1 spine growth during follow-up for all patients was 1.3 cm/year. There was one reoperation because of skin problems and no device-failures. Conclusion These early results show the feasibility and the proof of concept of spring-based distraction as a dynamic growth-enhancing system with the potential of further correction of the deformity after implantation.

Background: Partial avulsions of the proximal hamstring origin remain a challenging problem with nonoperative treatments frequently providing limited success. The literature is limited regarding the outcomes of operative management in the active and athletic population. Hypothesis: Surgical fixation of proximal hamstring ruptures will have favorable outcomes at midterm follow-up. Study design: Case series; Level of evidence, 4. Methods: A total of 64 patients with partial avulsions of the proximal hamstring origin treated with surgical fixation by a single surgeon were reviewed at a 2-year minimum follow-up. All patients had initially undergone failed nonoperative treatment. Patient-reported outcome scores on the Lower Extremity Functional Score (LEFS), Marx Activity Rating Scale, custom LEFS and Marx scales, and total proximal hamstring score were evaluated. Data on patient-perceived strength, return to sport, and satisfaction were also collected. Results: The cohort included 27 male and 37 female (N = 64) patients with a mean age of 47.3 years (range, 16-65 years), and all were reviewed at a mean 6.5-year (range, 2-12.5 years) follow-up. The average postoperative LEFS was 96% (range, 68%-100%), with the custom LEFS being 90% (range, 39%-100%). The mean Marx score was 12.4 (range, 4-16). The Marx custom score demonstrated no disability with activities of daily living. The mean total proximal hamstring score was 94% (range, 69%-100%). No differences in any outcome measures were seen when comparing acute versus chronic repairs. Three patients underwent further hamstring surgery. No patients reported symptoms of numbness in the operative extremity at rest, while 3 patients had a superficial stitch abscess treated with antibiotics alone. The most commonly reported difficulty was with prolonged sitting. Ninety-seven percent were satisfied with surgery, 92% reported they could participate in strenuous activity, and 97% estimated their strength to be >75%, while 64% estimated it to be 100% of their contralateral side. Patients returned to sport at an average of 11.1 months, and all that returned were satisfied with their performance. Conclusion: Both early and delayed anatomic surgical repair of partial proximal hamstring avulsions leads to successful functional outcomes, a high rate of return to athletic activity, and low complication rates at the 6.5-year follow-up. Nonoperative treatments should first be attempted.
