Cartilage has limited self-repair and <br />regeneration capacity. The ideal approach for articular cartilage defects is the regeneration of hyaline cartilage with <br />sustainable symptom-free constructs. Tissue engineering provides new strategies for the regeneration of functional <br />cartilage tissue through optimized scaffolds with architectural, mechanical, and biochemical properties similar to the <br />native cartilage tissue. In this review, the basic science of cartilage structure, interactions between proteins, stem cells, <br />as well as biomaterials, scaffold characteristics and fabrication methods, as well as current and potential therapies in <br />regenerative medicine will be discussed mostly from a biochemical point of view. Furthermore, the recent trends in <br />scaffold-based therapies and supplementary factors in cartilage tissue engineering will be considered. <br />Level of evidence: IMashhad University of Medical Sciences, Iranian Society of Knee Surgery, Arthroscopy and Sports Tramatology,Iranian Orthopaedic AssociationThe Archives of Bone and Joint Surgery2345-464410320220301Osteochondral Allografts for Large Osteochondral Lesions of the Knee Joint: Indications, Surgical Techniques and Results2452511916510.22038/abjs.2021.51810.2555ENE.

Dowel and shell t echniques are <br />the two most commonly used for OCA transplantation. The dowel technique is appropriate in most <br />cartilage lesions; however, geometrically irregular lesions may need the shell technique. Factors related <br />to better outcomes after OCA transplantation are the following: unipolar lesions; patients younger than <br />30 years; traumatic lesions; and when the treatment is carried out within 12 months from the onset of <br />symptoms. A systematic review found a survivorship rate of 89% at 5 years. Other systematic review <br />showed a mean failure rate of 25% at 12 years with a reoperation rate of 36%. Seventy -two per cent of <br />the failures were conversion to total knee arthroplasty (TKA) (68%) or unicompartmental knee <br />arthroplasty (UKA) (4%). Twenty-eight per cent of failures were graft removal, graft fixation, <br />and graft revision. In this systematic review, patellofemoral lesions (83%) had a higher reoperation rate <br />than lesions affecting the tibial plateau or the femoral condyles.

Different mechanisms are discussed in this process, and based on the involved mechanisms, <br />various agents and approaches are suggested for flap salvage. Among these agents and strategies, leech therapy <br />(hirudotherapy) can be a valuable complementary treatment; however, in this way, full attention should be given to all <br />beneficial and harmful aspects to reach the best results.<br />This study included a literature review of the essential complications following free tissue transfer and explained the <br />effects of leech therapy for the respective complications. <br />Based on the review of the literature, the essential complications following free tissue transfer were (I) venous obstruction <br />and congestion, (II) delay in blood flow reestablishment, (III) ischemia/reperfusion injuries, and (IV) thrombus formation. <br />Leech therapy can protect free flaps against the mentioned complications as a complementary treatment. <br />Leech therapy is an appropriate complement, however, not a definite approach for flap salvage.

The purpose of this study was to evaluate if both oral and intravenous preparations <br />of TXA are equivalent at reducing blood loss in the same patients undergoing staggered bilateral total knee arthroplasty.<br />Methods: 40 patients undergoing staggered bilateral total knee replacement were recruited. They received 2 g of oral <br />TXA 2 hours preoperatively for the first knee and 1 g of bolus intravenous TXA 15 minutes before skin incision for the <br />second knee. 7 patients were excluded for protocol deviation, leaving 33 participants for the study. The second knee <br />was operated within 5-6 days of the first knee. The primary outcome was reduction in hemoglobin. Equivalence was <br />tested with a two one-sided test (TOST) and a P < 0.05 indicated equivalence between oral and intravenous modes of <br />TXA administration. <br />Results: The mean reduction in hemoglobin was similar between oral and intravenous mode of TXA administration <br />(2.18 and 2.16 g/dl respectively, P<0.0001, equivalence). There was no significant difference in the total hemoglobin <br />loss and total red blood cell volume loss {(104 and 102 g, P=0.86) and (865 and 863 ml, P=0.53) respectively}. <br />Conclusion: Oral and intra venous TXA have equal blood sparing properties in patients undergoing staggered bilateral <br />total knee arthroplasty.<br />Level of evidence: IIMashhad University of Medical Sciences, Iranian Society of Knee Surgery, Arthroscopy and Sports Tramatology,Iranian Orthopaedic AssociationThe Archives of Bone and Joint Surgery2345-464410320220301Primary Results of Hook Plate Fixation Technique for Ulnar Collateral Ligament Fracture-Avulsion: A Case Study2672711864510.22038/abjs.2021.52295.2583ENAdel EbrahimpourDepartment of Orthopedic Surgery, Shohadaye Tajrish

A low-profile 2-mm stainless steel hook <br />plate with a 2-mm screw was used for the internal fixation. Immobilization was performed for 10 days. Range of motion <br />movements (ROM), grip power, and pinch strength were measured after three months. At the end of the follow-up <br />period, functional outcomes were determined by the visual analog scale (VAS), and Quick Disabilities of the Arm, <br />Shoulder, and Hand (Quick DASH). <br />Results: The mean follow-up period was reported as 12.4±2.3 months. the union of avulsed small osseous fragments <br />occurred at the end of the three-month follow-up. A number of 10 patients were treated by one hole 2-mm plate with <br />a screw and a mean VAS score of 22.5±2.4, while a female patient had more severe pain with a mean score of 45. <br />This patient complained about the irritation of the plate, especially in the thumb grip. The mean Quick DASH score was <br />9.6±1.4. The postoperative ROM was similar to that of the other side. Grip power and pinch strength were lower in the <br />treated thumb, as compared to that in the opposite side; nonetheless, the difference was not statistically significant. <br />Conclusion: As evidenced by the obtained results, it can be concluded that the hook plate technique is a strong <br />fixation method for thumb UCL fracture-avulsion, raising the possibility of earlier joint movements and rapid recovery; <br />nevertheless, in some cases, it can reduce efficiency and induce painful grip.<br />Level of evidence: IMashhad University of Medical Sciences, Iranian Society of Knee Surgery, Arthroscopy and Sports Tramatology,Iranian Orthopaedic AssociationThe Archives of Bone and Joint Surgery2345-464410320220301Effect of Intra-articular Dexmedetomidine on Postoperative Pain after Knee Arthroscopic Surgery2722771789610.22038/abjs.2021.53942.2706ENSholeh Nesioonpour1 Department of Anesthesiology,Pain Research Center,

It is hypothesized that there is no difference between intraarticular injection of dexmedetomidine and placebo after knee arthroscopy regarding pain level. <br />Methods: This double-blind randomized clinical trial was conducted on 70 patients aged 18-60 years who were <br />candidates for elective knee arthroscopic surgery with the American Society of Anesthesiologists Classification I-II. All <br />patients underwent spinal anesthesia equally and were randomly divided into two groups of 35 cases per group. The <br />drug group (D) received 2 μg/kg dexmedetomidine with 0.9% normal saline reached to a volume of 20 ml, and 20 ml of <br />0.9% normal saline was injected into the knee joint through the cannular sheath in the control group (C). Postoperative <br />pain intensity was recorded 1, 2, 4, 8, 16, 24 h after injection using the Visual Analogue Scale. The time of requesting <br />the first analgesic and the amount of analgesics consumed were recorded after 24 h.<br />Results: There was no significant difference between the two groups in terms of age, height, weight, duration of spinal <br />anesthesia, and duration of surgery (P>0.05). In group D, there was a decrease in postoperative pain, a decrease in <br />the amount of analgesic consumed, and an increase in the time of the first analgesic request, compared to group C <br />(P<0.05).<br />Conclusion: This study showed that intra-articular injection of dexmedetomidine relieved postoperative pain, reduced <br />analgesic consumption, and increased the time of first analgesic request after knee arthroscopy. <br />Level of evidence: IMashhad University of Medical Sciences, Iranian Society of Knee Surgery, Arthroscopy and Sports Tramatology,Iranian Orthopaedic AssociationThe Archives of Bone and Joint Surgery2345-464410320220301Smartphone Application Helps Improve the Accuracy of Cup Placement by Young, Less-Experienced Surgeons during Primary Total Hip Arthroplasty2782851864810.22038/abjs.2021.52402.2587ENAhmed A.KhalifaOrthopaedic Department, Qena Faculty of Medicine and

We aimed in this study to determine the accuracy of using intra-operative smartphone applications <br />(Apps) to place the acetabular cup within the safe abduction angle by less experienced surgeons during THA surgery <br />when compared to the conventional freehand technique for cup placement.<br />Methods: Sixty primary THAs were performed, 30 using the conventional freehand technique (control group) and 30 <br />using the smartphone app technique (study group) to determine the acetabular cup abduction angle by the same young <br />surgeon with less than one year of experience. Postoperative mean cup abduction angle, mean cup anteversion angle, <br />and the percentage of cups within the safe abduction zone as measured on radiographs were compared between the <br />two groups.<br />Results: In the study group, the mean cup abduction angle was significantly lower (P=0.0008), and the acetabular <br />cup was placed within the safe zone in a significantly higher (P<0.001) percentage of patients (93% vs 63%) when <br />compared to the control group. However, there was no significant difference (P=0.40) between the two groups when <br />the mean cup anteversion angle was compared.<br />Conclusion: The smartphone app technique may help achieve an accurate acetabular cup abduction angle and a <br />higher percentage of cups placed within the safe zone of abduction by a less experienced surgeon when compared to <br />the conventional freehand technique. Using tools such as the smartphone app to measure the acetabular cup position<br />can reduce intraoperative errors by young and less experienced surgeons during THA surgery.<br />Level of evidence: IVMashhad University of Medical Sciences, Iranian Society of Knee Surgery, Arthroscopy and Sports Tramatology,Iranian Orthopaedic AssociationThe Archives of Bone and Joint Surgery2345-464410320220301Epidemiology of Generalized Ligamentous Laxity in Iran: A National Study Including Different Iranian Ethnic Groups and its Relationship with Musculoskeletal Disorders2862921967210.22038/abjs.2022.56641.2813ENHossein SaremiDepartment of Orthopedics, Faculty of Medicine,

It can cause musculoskeletal and joint injuries. This national multi-centered study investigated the <br />epidemiology of generalized ligamentous laxity and its relationship with musculoskeletal disorders among Iranian <br />adults with different ethnic backgrounds.<br />Methods: A total of 1,488 people (age range: 17-40 years) were selected from eight cities and six different ethnicities <br />of Iran and included in this cross-sectional study. The presence of ligamentous laxity with clinical examinations was <br />searched according to Beighton score criteria. They were also examined for any kind of musculoskeletal disorders that <br />might accompany ligamentous laxity. The Chi-square test was used to compare the frequency of ligamentous laxity based <br />on gender and ethnicity; moreover, the t-test was utilized to compare the frequency of ligamentous laxity based on age.<br />Results: In total, 280 (18.8%) participants had generalized ligamentous laxity, and it was more prevalent in women <br />(22.7%), compared to men (14.4%). Regarding ethnicity, the highest and lowest prevalence rates were in Gilak (37.9%) <br />and Persian-Arab (6%) ethnicities, respectively (P<0.001). Ligamentous laxity showed a significant relationship with <br />sports injury, joint complaint, joint dislocation, ligament sprain, sciatica and back pain, Baker’s cyst, and varicose veins <br />(P<0.001). Most participants with generalized ligamentous laxity (93.6%) had no knowledge of their problem and its <br />importance in choosing an appropriate sports activity. <br />Conclusion: The prevalence of generalized ligamentous laxity seems to be relatively high among the 17-40-year-old <br />population of Iran, especially in women. It seems to be significantly related to ethnicity. It is strongly recommended <br />that examinations, screening, and information be provided at an early age in schools or at least in areas with a high <br />prevalence as national programs. <br />Level of evidence: IMashhad University of Medical Sciences, Iranian Society of Knee Surgery, Arthroscopy and Sports Tramatology,Iranian Orthopaedic AssociationThe Archives of Bone and Joint Surgery2345-464410320220301A Modified Semi-Lithotomy Position for Approach to Tibial Plateau Complex Fractures: A Technical Note2932961804710.22038/abjs.2021.54149.2707ENMohammad Tahami1 Bone and Joint Disease Research Center, Shiraz

The combined <br />approach used by many investigators has been found to be an effective method. However, combined approaches call <br />for repositioning the patient which lengthens the operation time. The sterility of the field of surgery might be jeopardized <br />by repositioning. Intraoperative fluoroscopic imaging is hard to adjust to both parts of the combined positions. To tackle <br />these problems without sacrificing the concept of three-column tibial plateau, we have started to use a combined medial <br />and lateral approach without repositioning the patients using a modified semi-lithotomy position. <br />Level of evidence: VMashhad University of Medical Sciences, Iranian Society of Knee Surgery, Arthroscopy and Sports Tramatology,Iranian Orthopaedic AssociationThe Archives of Bone and Joint Surgery2345-464410320220301Dr. Charles Adelbert Rockwood(1929-2022)2972981973210.22038/abjs.2022.63586.3066ENMohammad H.
