Background and purpose - Cartilage damage can develop due to trauma, resulting in focal chondral or osteochondral defects, or as more diffuse loss of cartilage in a generalized organ disease such as osteoarthritis. A loss of cartilage function and quality is also seen with increasing age. There is a spectrum of diseases ranging from focal cartilage defects with healthy surrounding cartilage to focal lesions in degenerative cartilage, to multiple and diffuse lesions in osteoarthritic cartilage. At the recent Aarhus Regenerative Orthopaedics Symposium (AROS) 2015, regenerative challenges in an ageing population were discussed by clinicians and basic scientists...

Knee pain in young, active patients with meniscus-deficient knees and articular cartilage damage can present a challenge to treatment. Meniscal allograft transplantation (MAT) has shown good clinical results as treatment for meniscus deficiency; however, worse outcomes have been observed in patients with significant chondral damage. The development of chondral restorative techniques such as osteochondral allograft transplantation (OCA) has expanded the population of patients who may benefit from MAT. We present a case of proximal tibial osteochondral and lateral meniscal allograft transplant...

: Identification, protection, and management of patellofemoral articular cartilage lesions continue to remain on the forefront of sports medicine rehabilitation. Due to high-level compression forces that are applied through the patellofemoral (PF) joint, managing articular cartilage lesions is challenging for sports medicine specialists. Articular cartilage damage may exist in a wide spectrum of injuries ranging from small, single areas of focal damage to wide spread osteoarthritis involving large chondral regions...

Anterior cruciate ligament (ACL) reconstruction is common in the active young population. Failure of ACL reconstruction can be due to continued or recurrent instability, stiffness, or patient-reported failure in the setting of seemingly successful surgical reconstruction, such as pain that limits activity. Multiple preoperative, intraoperative, and postoperative variables can be optimized to give the greatest likelihood of success. Some of these include timing of surgery, identification, and treatment of associated ligamentous, meniscal and chondral injuries, tunnel placement, graft choice, fixation, tensioning, and postoperative rehabilitation...

Following anterior cruciate ligament (ACL) rupture, reconstructive surgery (ALCR) is often performed to mechanically stabilise the knee, however functional deficits often persist long after surgery. Impaired single-limb standing balance has been observed in the ACLR limb compared to healthy individuals. However, it remains inconclusive as to whether these same balance deficits exist between the injured and contralateral uninjured limbs, during challenging balance tasks, and at a time when patients are permitted to return to sport...

Proteins of the transforming-growth-factor-β (TGF-β)-superfamily have a remarkable ability to induce cartilage and bone and the crosstalk of TGF-β - and BMP-signalling pathways appears crucial during chondrocyte development. Aim was to assess the regulation of TGF-β-superfamily members and of Smad2/3- and Smad1/5/9-signalling during endochondral in vitro chondrogenesis of mesenchymal stromal cells (MSC) relative to chondral redifferentiation of articular chondrocytes (AC) to adjust chondrocyte development of MSC towards a less hypertrophic phenotype...

The present study aims to investigate the physical-chemical and biological features exhibited by porous scaffolds for regeneration of cartilaginous tissues obtained through stabilization of 3D gelatin hydrogels by physical (DHT), chemical (BDDGE) and natural (Genipin) cross-linking approaches. The study aimed at comparatively assessing the porous microstructure and the long-term resistance of the scaffolds upon degradation in wet physiological conditions (37°C, pH=7.4). The degree of cross-linking increases as function of incorporation of cross-linkers which was maximum up to 73% for BDDGE...

BACKGROUND: Non-arthritic hip disorders are defined as abnormalities of the articulating surfaces of the acetabulum and femur before the onset of osteoarthritis, including intra-articular structures such as the acetabular labrum and chondral surfaces. Abnormal femoroacetabular morphology is commonly seen in young men who constitute much of the UK military population. Residential multidisciplinary team (MDT) rehabilitation for patients with musculoskeletal injuries has a long tradition in the UK military, however, there are no studies presenting empirical data on the efficacy of a residential MDT approach compared with individualised conventional outpatient treatment...

BACKGROUND: The main option to perform an anatomic anterior cruciate ligament (ACL) reconstruction is the anteromedial portal (AMP) technique. It has several reported complications (iatrogenic chondral injury, posterior-wall blowout, short sockets, increased risk of injury to common peroneal nerve). In an attempt to avoid these complications the outside-in (OI) technique was revived with the addition of a retrodrill. The aim of this study is to evaluate the clinical and arthrometric outcomes of a series of anatomical OI single bundle ACL reconstruction using a retrodrill...

Femoroacetabular impingement (FAI) is one of the most researched conditions in sports medicine today. FAI occurs due to abnormal morphology and subsequently contact between the proximal femur and the acetabulum. With repetitive loading, this femoroacetabular mismatch can be a source of labral and chondral injuries. FAI is more prevalent in the athletic population, particularly those athletes who participated in high level activities at a younger age. If nonoperative management is failed, surgical treatment is often done arthroscopically and with good results...

BACKGROUND: Different surgical approaches are currently available to treat knee chondral defects. Microfracture is the most commonly applied, but it often leads to a mechanically inferior fibrocartilaginous tissue. To overcome this shortcoming, the Autologous, Matrix-Induced Chondrogenesis (AMIC) technique has been proposed. To further enhance the outcome of AMIC, the addition of haemoderivatives containing growth factors that stimulate cartilage healing has emerged as a new treatment method...

BACKGROUND: Rupture of the anterior cruciate ligament (ACL) is a common sports injury and is known to be associated with an increased risk of knee osteoarthritis. Several studies have indicated that the risk of additional injuries to the menisci and articular cartilage increases with delays in the treatment of ACL tears. However, no consensus has been reached regarding the ideal timing for ACL reconstruction in terms of preventing secondary lesions. PURPOSE: To determine how the time elapsed between an ACL lesion and its reconstruction affects the incidence of meniscal and chondral lesions...

BACKGROUND: Treating articular cartilage defects and meniscal deficiency is challenging. Although some short- to mid-term follow-up studies report good clinical outcomes after concurrent autologous chondrocyte implantation (ACI) and meniscal allograft transplantation (MAT), longer follow-up is needed. PURPOSE: To evaluate mid- to long-term outcomes after combined ACI with MAT. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: We performed a retrospective review of prospectively gathered data from patients who had undergone ACI with MAT between 1999 and 2013...
