Abstract	Background: Osteochondromas, classified as a new benign subtype of lipomas and characterised by chondroid and osseous differentiation, are rare lesions that have been infrequently reported in previous literature. The maxillofacial region was reported as the most frequent localization, with infrequent occurrence in the lower limb. This paper represents the first documented case report of osteochondrolipoma in the foot. Case presentation: A 51-year-old male patient presented with a chief complaint of right foot pain at the plantar aspect, accompanied by the observation of swelling between the first and the second metatarsal shafts. His complaint of pain and swelling started 10 and 4 years prior, respectively. Since their onset, both symptoms have progressed in nature. Imaging revealved a large mass exhibiting a nonhomogenous composition of fibrous tissue and bony structures. Surgical intervention through total excision was indicated. Conclusion: Osteochodrolipoma is a benign lesion that can affect the foot leading to decreased functionality of the foot due to the pain and swelling. Surgical excision is the recommended approach for this lesion, providing both symptomatic relief and confirmation of the diagnosis through histopathological examination.

Abstract	Arthroscopic reconstruction of the anterior cruciate ligament has been modernized through new materials and novel surgical techniques. The usage of bioabsorbable screws for tibial fixation may potentially lead to complications, such as formation of a tibial tunnel or pretibial cysts. This is a relatively rare complication, but it has been described in the literature. The pathomechanism of cyst formation, however, still remains poorly understood. In this case report, we present a case of a healthy 23-year-old gentleman who had left tibia vara, which was treated surgically with proximal tibia corrective osteotomy with plate and screw fixation and subsequent hardware removal. Later in his life, he injured his anterior cruciate ligament, which required arthroscopic reconstruction. Years after, he developed a pretibial synovial cyst, which was visualized on magnetic resonance imaging. We reviewed previously published cases with similar presentations to help describe the possible etiology of intraosseous (tibial tunnel) cysts.

Abstract	Charcot knee is a rare condition with few reported cases in the literature. Although the clinical presentation is highly variable, Charcot knee classically presents with painful arthropathy in addition to instability and decreased range of motion. Herein, we describe the case of a 72-year-old man with idiopathic Charcot knee. The diagnosis was established on the basis of history of neuropathic arthropathy of the knee, supported by knee radiographs and the exclusion of all known etiologies of Charcot knee. Because of a highly destructed knee joint, the patient underwent a total knee arthroplasty using the Global Modular Replacement System proximal tibial prosthesis. The surgery was done without any major complications, resulting in symptomatic and functional improvements.

Abstract	Two commercially available porous coatings, Gription and Porocoat, were compared for the first time in a challenging intra-articular, weight-bearing, ovine model. Gription has evolved from Porocoat and has higher porosity, coefficient of friction, and microtextured topography, which are expected to enhance bone ingrowth. Cylindrical implants were press-fit into the weight-bearing regions of ovine femoral condyles and bone ingrowth and fixation strength evaluated 4, 8, and 16 weeks postoperatively. Biomechanical push-out tests were performed on lateral femoral condyles (LFCs) to evaluate the strength of the bone-implant interface. Bone ingrowth was assessed in medial femoral condyles (MFCs) as well as implants retrieved from LFCs following biomechanical testing using backscattered electron microscopy and histology. By 16 weeks, Gription-coated implants exhibited higher force (2455 ± 1362 vs. 1002 ± 1466 N; p = 0.046) and stress (12.60 ± 6.99 vs. 5.14 ± 7.53 MPa; p = 0.046) at failure, and trended towards higher stiffness (11,510 ± 7645 vs. 5010 ± 8374 N/mm; p = 0.061) and modulus of elasticity (591 ± 392 vs. 256 ± 431 MPa; p = 0.061). A strong, positive correlation was detected between bone ingrowth in LFC implants and failure force (r = 0.93, p < 10

Abstract	Background: Unilateral laminotomy with bilateral spinal canal decompression has gained popularity recently. Aim: To systematically review the literature of unilateral laminotomy with bilateral spinal canal decompression for lumbar spinal stenosis (LSS) aiming to assess outcomes and complications of the different techniques described in literature. Methods: On August 7, 2022, Pubmed and EMBASE were searched by 2 reviewers independently, and all the relevant studies published up to date were considered based on predetermined inclusion and exclusion criteria. The subject headings "unilateral laminotomy", "bilateral decompression" and their related key terms were used. The Preferred Reporting Item for Systematic Reviews and Meta-Analyses statement was used to screen the articles. Results: A total of seven studies including 371 patients were included. The mean age of the patients was 69.0 years (range: 55-83 years). The follow up duration ranged from 1 to 3 years. Rate of postoperative pain and functional improvement was favorable based on VAS, JOA, JOABPEQ, RMDW, ODI and SF-36, for example improved from a range of 4.2-7.5 preoperatively on the VAS score to a range of 1.4-3.0 postoperatively at the final follow up. Insufficient decompression was noted in 3% of the reported cases. The overall complication rate was reported at 18-20%, with dural tear at 3.6-9% and hematoma at 0-4%. Conclusion: Unilateral laminotomy with bilateral decompression has favorable short- and mid-term pain and functional outcomes with low recurrence and complication rates. This, however, needs to be further confirmed in larger, long-term follow-up, prospective, comparative studies between open, and minimally invasive techniques.

Abstract	Introduction: Dermatofibrosarcoma protuberans (DFSP) is a rare cutaneous tumour of indeterminate malignant potential. The mainstay treatment for DFSP is surgical resection. Given the reported high local recurrence rate, the ideal resection margin for DFSP is unclear. The purpose of this study was to ascertain the local recurrence and metastatic rate of DFSP and DFSP with fibrosarcomatous degeneration (FS-DFSP), with specific attention to margin status in an attempt to address the issue of margin adequacy. Methods: Patients treated for DFSP at a single sarcoma centre were identified from a prospective database. DFSP and FS-DFSP patients with and without prior surgery were included. Patients were followed after surgery to monitor complications, local recurrence and metastasis. Results: The study included 200 patients: 166 patients with DFSP and 34 patients with FS-DFSP. In the DFSP group, nine patients (5.4%) had positive margins, one case (0.6%) developed local recurrence (LR) and no patients developed distant metastases. In the FS-DFSP group, seven patients (20.6%) had positive margins, six patients (17.6%) developed local recurrence (LR) and eight patients (23.5%) developed distant metastases, of which three (37.5%) were in the lungs, one (12.5%) in bone and four (50%) in other soft tissue sites. Discussion and conclusion: Local recurrence and metastases are extremely rare in patients with DFSP. Achieving a negative as opposed to a wide surgical margin may be sufficient to avoid local recurrence of most DFSP. We suggest that no ongoing surveillance for local or systemic relapse is required for DFSP patients after negative margin resection. For FS-DFSP, we recommend the same surveillance schedule, based on tumour grade, as other soft tissue sarcoma.

Abstract	Introduction: While intraoperative navigation systems have been shown to improve outcomes in primary total hip arthroplasty (THA), their use in the context of revision has been largely overlooked. This case report presents the first documented use of an imageless navigation tool in the context of revision THA, and an unexpected benefit to the surgical procedure as a result. Case report: An 84-year-old female patient presented following five episodes of dislocation of the left hip and with pain in the left buttock, groin, and posterior aspect of her hip. Relevant surgical history included primary hip arthroplasty in 1999 and the first revision in 2014. Preoperative analysis revealed a constrained liner that had become disengaged and migrated inferiorly, lodging at the distal aspect of the femoral neck. Acetabular protrusion was also noted. The pre-operative plan included the replacement of the fragmented liner and likely of the acetabular cup due to hardware failure. Intraoperative assessment, however, revealed that the cup was in good condition and would be difficult to remove due to substantial bony ingrowth. With the assistance of imageless navigation, the orientation of the acetabular cup was determined and a new constrained liner was cemented into the preexisting acetabular component at an altered orientation, correcting anteversion by 7°. Conclusions: In revision hip arthroplasty cases, image-based navigation is limited by the presence of existing implants and corresponding metal artefact. This case demonstrates the successful use of an imageless navigation tool for revision surgery. Use of navigation led to the unexpected intraoperative discovery that the acetabular cup was in an acceptable state, and allowed the surgical team to correct the position of the cup using a constrained liner, thus preserving the cup. This significantly benefitted patient outcome, due to the risks associated with the removal of a firmly fixated acetabular cup. While more extensive research is required, this case demonstrates that imageless navigation may be an indispensable tool for revision surgery.

Abstract	Aims: The aim of this study was to assess the effects of transferring patients to a specialized arthroplasty centre between the first and second stages (interstage) of prosthetic joint infection (PJI) of the knee. Patients and methods: A search of our institutional database was performed to identify patients having undergone two-stage revision total knee arthroplasty (TKA) for PJI. Two cohorts were created: continuous care (CC) and transferred care (TC). Baseline characteristics and outcomes were collected and compared between cohorts. Results: A total of 137 patients were identified: 105 in the CC cohort (56 men, 49 women; mean age 67.9) and 32 in the TC cohort (17 men, 15 women; mean age 67.8 years). PJI organism virulence was greater in the CC cohort (36.2% Conclusion: Patient transfer during the interstage of treatment for infected TKA leads to poorer outcomes compared with patients receiving all their treatment at a specialized arthroplasty centre.

Abstract	Background: The Harris Hip Score (HHS) questionnaire has been translated and validated into many languages including Italian, Portuguese, and Turkish but not Arabic. The goal of this study was to translate HHS into the Arabic language with cross-cultural adaptation to include and benefit Arabic speaking communities as it is the most widely used instrument for disease-specific hip joint evaluation and measurement of total hip arthroplasty outcome. Methods: This questionnaire was translated following a clear and user-friendly guideline protocol. The Cronbach's alpha was used to assess the reliability and internal consistency of the items of HHS. Additionally, the constructive validity of HHS was evaluated against the 36-Item Short Form Survey (SF-36). Results: A total of 100 participants were included in this study, of which 30 participants were re-evaluated for reliability testing. Cronbach's alpha of the total score of Arabic HHS is 0.528, and after the standardization, it changed to 0.742 which is within the recommended range (0.7-0.9). Lastly, the correlation between HHS and SF-36 was r = 0.71 ( Conclusions: Based on the results, we believe that the Arabic HHS can be used by clinicians, researchers, and patients to evaluate and report hip pathologies and total hip arthroplasty treatment efficacy.

Abstract	Background: Lymph node metastases (LNM) rarely occur in adult extremity soft-tissue sarcoma (STS), affecting approximately 5% of patients. To the authors' knowledge, few studies to date have evaluated the prognosis and survival of patients with LNM. Methods: A retrospective review was performed of a single-center, prospectively collected STS database. Demographic, treatment, and oncologic data for patients with STS of the extremity with LNM were obtained from clinical and radiographic records. Results: Of 2689 patients with extremity STS, a total of 120 patients (4.5%) were diagnosed with LNM. LNM occurred most frequently among patients diagnosed with clear cell sarcoma (27.6%), epithelioid sarcoma (21.9%), rhabdomyosarcoma (17.3%), angiosarcoma (14.0%), and extraskeletal myxoid chondrosarcoma (9.3%). A total of 98 patients (81.7%) underwent LNM surgical resection. Patients with isolated LNM had a greater 5-year overall survival (57.3%) compared with patients with American Joint Committee on Cancer (AJCC) eighth edition stage IV STS with only systemic metastases (14.6%) or both LNM and systemic disease (0%; P < .0001). Patients with isolated LNM had an overall survival rate (52.9%) similar to that of patients with localized AJCC stage III tumors (ie, large, high-grade tumors) (49.3%) (P = .8). Patients with late, isolated, metachronous LNM had a 5-year overall survival rate (61.2%) that was similar to that of patients with isolated synchronous LNM at the time of presentation (53.6%) (P = .4). Conclusions: Many different types of STS develop LNM. Patients with extremity STS with isolated LNM should not be considered as having stage IV disease as they are according to the current AJCC eighth edition classification because they have significantly better survival than those with systemic metastases. Patients with isolated, late, metachronous LNM have a survival similar to that of patients with isolated synchronous LNM at the time of presentation. Lay summary: The results of the current study demonstrated that patients diagnosed with isolated lymph node metastases have a prognosis similar to that of patients diagnosed with localized American Joint Committee on Cancer stage III soft-tissue sarcomas, which also equates to a significantly better overall survival compared with patients with systemic metastases. Therefore, the authors recommend modifications to the most recent eighth edition of the American Joint Committee on Cancer staging system to clearly distinguish patients with isolated lymph node metastases to acknowledge their better prognosis compared with those with systemic metastases.
