Abstract
Cartilage defects caused by joint diseases are difficult to treat clinically. Tissue engineering materials provide a new means to promote the repair of cartilage defects. The purpose of this study is to design a novel scaffold of porous magnesium alloy loaded with icariin and sustained release in order to explore the effect and possible mechanism of this scaffold in repairing SD rat knee articular cartilage defect. We constructed a novel type of icariin/porous magnesium alloy scaffold, observed the structure of the scaffold by electron microscope, detected the drug release of icariin in the scaffold and the biological safety, and established an animal model of cartilage defect in the femoral intercondylar fossa of the knee joint in rats; the scaffold was placed in the defect. After 12 weeks of repair, the rat knee articular cartilage repair was evaluated by gross specimens and micro-CT, HE, safranin O-fast green, and toluidine blue staining combined with the modified Mankin's score. The protein expressions of the Wnt/β-catenin signaling pathway-related factors (β-catenin, Wnt5a, Wnt1, sFRP1) and chondrogenic differentiation-related factors (Sox9, Aggrecan, Col2α1) were detected by immunohistochemical staining. We found that the novel scaffold of icariin/porous magnesium alloy can release icariin slowly and has biosafety in rats. Compared with other groups, icariin/porous magnesium alloy can significantly promote the repair of cartilage defects and the expressions of β-catenin, Wnt5a, Wnt1, Sox9, Aggrecan, and Col2α1 (P < 0.05). This novel scaffold can promote the repair of rat knee cartilage defects, and this process may be achieved by activating the Wnt/β-catenin signaling pathway.

Abstract
Tissue engineered scaffolds are needed to support physiological loads and emulate the micrometer-scale strain gradients within tissues that guide cell mechanobiological responses. We designed and fabricated micro-truss structures to possess spatially varying geometry and controlled stiffness gradients. Using a custom projection microstereolithography (μSLA) system, using digital light projection (DLP), and photopolymerizable poly(ethylene glycol) diacrylate (PEGDA) hydrogel monomers, three designs with feature sizes < 200 μm were formed: (1) uniform structure with 1 MPa structural modulus ( E ) designed to match equilibrium modulus of healthy articular cartilage, (2) E = 1 MPa gradient structure designed to vary strain with depth, and (3) osteochondral bilayer with distinct cartilage ( E = 1 MPa) and bone ( E = 7 MPa) layers. Finite element models (FEM) guided design and predicted the local mechanical environment. Empty trusses and poly(ethylene glycol) norbornene hydrogel-infilled composite trusses were compressed during X-ray microscopy (XRM) imaging to evaluate regional stiffnesses. Our designs achieved target moduli for cartilage and bone while maintaining 68-81% porosity. Combined XRM imaging and compression of empty and hydrogel-infilled micro-truss structures revealed regional stiffnesses that were accurately predicted by FEM. In the infilling hydrogel, FEM demonstrated the stress-shielding effect of reinforcing structures while predicting strain distributions. Composite scaffolds made from stiff μSLA-printed polymers support physiological load levels and enable controlled mechanical property gradients which may improve in vivo outcomes for osteochondral defect tissue regeneration. Advanced 3D imaging and FE analysis provide insights into the local mechanical environment surrounding cells in composite scaffolds.

Abstract
Chondral defects in the athlete's hip are a relatively common occurrence, often presenting with debilitating pain and activity limitation. Preoperative identification of cartilage defects is challenging and there are many different modalities for treatment. Nonsurgical interventions, including activity modification, physical therapy, and injections, play a vital role, especially in less severe cases and as adjuncts to surgical intervention. Treating surgeons must be familiar with the cartilage restoration procedures available, including debridement, microfracture, and various implantation and transplantation options. Safe and effective management of cartilage defects is imperative to an athlete's return to sport. It is also imperative that surgeons are aware of all these various treatment options to determine what modality is best for their patients. This review serves to outline these options, cover the published literature, and provide general guidelines for surgeons when they encounter chondral defects in the office and the operating room.

Abstract
A narrative review of the literature was conducted to examine the data on femoral head fractures, with a particular focus on their management, complications and clinical outcomes. A PRISMA strategy was used. Medline and Scopus library databases were queried using pre-defined MeSH terms and Boolean operators. Quality of evidence was evaluated based on OCEBM and GRADE systems. The 50 eligible articles that met the predefined inclusion criteria reported on 1403 femoral head fractures. A detailed analysis of the surgical approaches used was performed in 38 articles with 856 fractures. Most fractures were treated surgically (90,8 %) with preferred anatomical reconstruction in 76,7 % of all operatively treated cases. Posterior approaches were the most common (52.5 %). This was evenly split between surgical hip dislocation and the classic Kocher-Langenbeck approach. 70.5 % of surgically treated cases achieved excellent or good result according to Thompson-Epstein criteria. Highest rate of excellent results showed minimal invasive osteosynthesis and surgical hip dislocation. Major late complications were avascular necrosis (10.8 %), post-traumatic arthritis (16.2 %) and heterotopic ossification (20.8 %). Secondary THA was necessary in 6.9 %. Highest rate of major complications was joined with anterior approach (77 %), lowest rate from frequently used approaches surgical hip dislocation (37.8 %). Conservative treatment recedes into the background. The Ganz flip osteotomy with surgical hip dislocation allows safe treatment of all types of fractures and should be considered the first choice, offering the lowest rate of complications and one of the best functional outcomes. Reconstruction of Pipkin Type III fractures should be reserved for very young patients due to high rate of major complications.

Arthroscopy 2024:S0749-8063(24)00295-0. [PMID: 38677565 DOI: 10.1016/j.arthro.2024.03.048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2024] [Revised: 03/30/2024] [Accepted: 03/30/2024] [Indexed: 04/29/2024]
Abstract
Articular cartilage defects of the hip pose therapeutic challenges. Among patients undergoing hip arthroscopy for femoroacetabular impingement syndrome, more than 20% may have partial- or full-thickness chondral damage, and patients with high-grade (International Cartilage Repair Society grade 3 or 4) damage who undergo arthroscopic treatment of femoroacetabular impingement syndrome have higher rates of reoperation at 10-year follow-up. Arthroscopic and open techniques have been developed to translate cartilage restoration options initially developed in the knee for use in the hip. Arthroscopic options include chondroplasty, microfracture, biologic cartilage scaffolds, autologous chondrocyte implantation, and minced cartilage autograft (albeit more commonly in the acetabulum than the femoral head). Open techniques include autologous chondrocyte grafting, osteochondral autograft transfer (including mosaicplasty), osteochondral allograft transplantation, and arthroplasty. Open osteochondral allograft and autograft transplantation show improved patient-reported outcomes and forestall arthroplasty in young patients with high-grade cartilage defects of the femoral head. A recent review shows survivorship of 70% to 87.5% for allograft and 61.5% to 96% for autograft. At the same time, outcomes are not universally positive, particularly for patients with posttraumatic impaction injuries and high-grade osteonecrosis. Until further data better clarify the indications and contraindications, widespread adoption of open cartilage transplantation to the femoral head should be approached with caution, especially for older patients, in whom the gold standard of total hip arthroplasty has excellent survivorship at long-term follow-up.

Abstract
PURPOSE To review patient-reported outcomes (PROs) and survivorship in patients undergoing osteochondral autograft or allograft transplantation (OAT) of the femoral head. METHODS PubMed, Cochrane Center for Register of Controlled Trials, and Scopus databases were searched in November 2022 with an updated search extending to December 2023 using criteria from the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and the following keywords: (hip OR femoral head) AND (mosaicplasty OR osteochondral allograft OR osteochondral autograft OR osteochondral lesion). Articles were included if they evaluated postoperative PROs in patients who underwent OAT of the femoral head and had a study size of 5 or more hips (n ≥ 5). Survivorship was defined as freedom from conversion to total hip arthroplasty. For PROs evaluated in 3 studies or more, forest plots were created and I2 was calculated. RESULTS Twelve studies were included in this review, with a total of 156 hips and a mean follow-up time ranging between 16.8 and 222 months. In total, 104 (66.7%) hips were male while 52 (33.3%) were female. Age of patients ranged from 17.0 to 35.4 years, while body mass index ranged from 23.3 to 28.1. Eight studies reported on osteochondral autograft transplantation and 4 studies on osteochondral allograft transplantation. Three studies reported significant improvement in at least 1 PRO. Survivorship ranged from 61.5% to 96% at minimum 2-year follow-up and from 57.1% to 91% at minimum 5-year follow-up. At a follow-up of less than 5 years, osteochondral allograft transplantation studies showed 70% to 87.5% survivorship, while autograft varied from 61.54% to 96%. CONCLUSIONS Patients with osteochondral lesions of the femoral head who underwent osteochondral autograft or allograft transplantation demonstrated improved PROs but variable survivorship rates. LEVEL OF EVIDENCE Level IV, systematic review of Level IV studies.

An evidence-based update on the management of articular cartilage defects in the hip. J Clin Orthop Trauma 2022; 28:101830.

Abstract
Objective Articular cartilage defects in the hip joint pose a significant surgical challenge and remain one of the most important determinants of success following arthroscopic intervention of the hip. The aim of this literature review was to report on the best available evidence on the various treatment options utilised for articular cartilage defects in the hip. Material and methods A comprehensive literature search was performed on PubMed from its inception to October 2021 using the following search strategy: ((hip) and (cartilage or chondral) and (repair or regeneration or restoration or implantation or chondroplasty or chondrogenic)). Two reviewers (KHSK, MG) independently reviewed titles and abstracts to identify articles for the final analysis. Articles were included if they were original research studies (randomised control trials, cohort studies, case-control studies, or comparative studies) on treatment of hip cartilage defects in humans reporting on a minimum of 5 patients. A total of 1172 articles were identified from the initial literature search. Following a thorough selection process, 35 articles were included in the final analysis to synthesise the evidence. Results Debridement, microfracture, autologous chondocyte implanatation (ACI) and matrix-induced ACI (MACI) are shown to have good short-to medium-term results. Injectable ACI and MACI have been developed to enable these procedures to be performed via arthroscopic surgery to reduce the post-operative morbidity associated with surgery with promising early results. Large cartilage defects which involved the sub-chondral bone may need the use of osteochondral grafts either autograft or allograft. Newer biological solutions have been developed to potentially deliver a single-stage procedure for hip cartilage injuries but longer-term results are still awaited. Conclusion Accurate identification of the extent of the injury helps stratify the defect and plan appropriate treatment. Several surgical techniques have shown good short to medium-term outcomes with ACI, AMIC, mosaicplasty and microfracture. Recent advances have enabled the use of injectable MACI and bioscaffolds which show promising results but in the shorter term. However, one needs to be mindful of the techniques which can be used in their surgical setting with the available resources. In order to thoroughly evaluate the benefits of the different surgical techniques for hip cartilage defects, large scale prospective multi-centre studies are necessary. Perhaps inclusion of such procedures in registries may also yield meaningful and pragmatic results.

Abstract
BACKGROUND The regeneration and repair of articular cartilage remains a major challenge for clinicians and scientists due to the poor intrinsic healing of this tissue. Since cartilage injuries are often clinically irregular, tissue-engineered scaffolds that can be easily molded to fill cartilage defects of any shape that fit tightly into the host cartilage are needed. METHOD In this study, bone marrow mesenchymal stem cell (BMSC) affinity peptide sequence PFSSTKT (PFS)-modified chondrocyte extracellular matrix (ECM) particles combined with GelMA hydrogel were constructed. RESULTS In vitro experiments showed that the pore size and porosity of the solid-supported composite scaffolds were appropriate and that the scaffolds provided a three-dimensional microenvironment supporting cell adhesion, proliferation and chondrogenic differentiation. In vitro experiments also showed that GelMA/ECM-PFS could regulate the migration of rabbit BMSCs. Two weeks after implantation in vivo, the GelMA/ECM-PFS functional scaffold system promoted the recruitment of endogenous mesenchymal stem cells from the defect site. GelMA/ECM-PFS achieved successful hyaline cartilage repair in rabbits in vivo, while the control treatment mostly resulted in fibrous tissue repair. CONCLUSION This combination of endogenous cell recruitment and chondrogenesis is an ideal strategy for repairing irregular cartilage defects.

Abstract
The aim of the present study was to present clinical and radiological outcome of a hip fracture-dislocation of the femoral head treated with biomimetic osteochondral scaffold. An 18-year-old male was admitted to the hospital after a motorcycle-accident. He presented with an obturator hip dislocation with a type IVA femoral head fracture according to Brumback classification system. The patient underwent surgery 5 days after accident. The largest osteochondral fragment was reduced and stabilized with 2 screws, and the small fragments were removed. The residual osteochondral area was replaced by a biomimetic nanostructured osteochondral scaffold. At 1-year follow-up the patient did not complain of hip pain and could walk without limp. At 2-year follow-up he was able to run with no pain and he returned to practice sports. Repeated radiographs and magnetic resonance imaging studies of the hip showed no signs of osteoarthritis or evidence of avascular necrosis. A hyaline-like signal on the surface of the scaffold was observed with restoration of the articular surface and progressive decrease of the subchondral edema. The results of the present study showed that the biomimetic nanostructured osteochondral scaffold could be a promising and safe option for the treatment of traumatic osteochondral lesions of the femoral head.

Abstract
Titanium implants have been widely used as one of the most effective treatments of bone defects. However, the lack of osteogenesis and bacteria-resistant activities result in high infection and loosening rates of titanium implants. Anodic oxidation could easily construct titanium dioxide nanotubes (TNTs) array on the surface of titanium, and the rough surface of TNTs is beneficial to the growth of osteoblast-related cells on the surface. And TNTs could be excellent drug carriers because of their single-entry tubular hollow structure. In this review, we aim at detailing the application of TNTs as drug carriers in the field of bone implants. Starting from the topography of TNTs, we illustrated the biological activity of the TNTs surface, the drugs for loading in TNTs, and the controlled and responsive release strategies of drug-loaded TNTs, respectively. At the end of this review, the shortcomings of TNTs as the drug carrier in the field of bone implants are discussed, and the development direction of this research field is also prospected.

Abstract
Bone marrow stromal stem cells (BMSCs) can be used to treat bone defects but BMSCs are damaged under oxidative stress. The neuropeptide substance P (SP) involves various cellular activities. However, SP’s role in BMSCs differentiation under oxidative stress is unknown. Rat BMSCs
were isolated and assigned into control group; oxidative stress group treated with 200 μM H2O2; and SP group, in which 10 mM SP was added under oxidative stress followed by analysis of SP secretion by ELISA, cell proliferation by MTT method, Caspase3 activity, Bax
and Bcl-2 level by Real time PCR, ALP activity ROS and SOD content as well as NF-κB level by Western blot. Under oxidative stress, SP secretion was significantly decreased, BMSCs proliferation was inhibited, Caspase3 activity and Bax expression increased, Bcl-2 and ALP activity was decreased
along with increased ROS activity and NF-κB level and reduced SOD activity (P <0.05), adding SP to BMSCs under oxidative stress can significantly promote SP secretion and cell proliferation, reduce Caspase3 activity and Bax expression, increase Bcl-2 expression and ALP activity,
decreased ROS activity and NF-κB level, and elevated SOD activity (P <0.05). SP secretion from BMSCs cells was reduced under oxidative stress. Up-regulation of SP in BMSCs cells under oxidative stress can inhibit BMSCs apoptosis and promote cell proliferation and osteogenesis
by regulating NF-κB.
