Similar Clinical Outcomes for Arthroscopic Labral Reconstruction in Irreparable Cases Using the Indirect Head of the Rectus Femoris Tendon With an All-Inside Technique for Small Defects and the Iliotibial Band for Large Defects.

Purpose: To evaluate the clinical outcomes and satisfaction rate of patients who underwent arthroscopic labral reconstruction for an irreparable labral tear with a minimum follow-up period of 2 years. Additionally, this study aimed to compare 2 different reconstructive techniques for small and large labral defects: the indirect head of the rectus femoris tendon (IHRFT) autograft with an all-inside technique used to repair small defects (≤3 hours) and the iliotibial band (ITB) autograft for large defects (>3 hours).

Methods: A total of 24 hips treated with the IHRFT were compared with 24 hips treated with the ITB.

Satisfactory results after endoscopic gluteus medius repair combined with selective gluteus maximus reflected tendon release for the treatment of a full-thickness tear of gluteus medius.

Purpose: The current study aimed to report the mid-term follow-up results of endoscopic gluteus medius repair combined with a systematic release of the gluteus maximus reflected tendon.

Methods: Twenty-two patients with a symptomatic full-thickness tear of the gluteus medius tendon, as diagnosed by clinical examination and imaging (MRI), and who had a failure of conservative treatment for at least 6 months, were retrospectively enrolled for this study. An endoscopic repair of gluteus medius was performed for all patients in combination with gluteus maximus reflected tendon release according to the Polesello technique.

In vitro evidence for the involvement of HS pathway in the effect of clodronate during inflammatory response.

Clodronate is a bisphosphonate agent commonly used as anti-osteoporotic drug. Throughout its use, additional anti-inflammatory and analgesic properties have been reported, although the benefits described in the literature could not solely relate to their inhibition of bone resorption. Thus, the purpose of our in vitro study is to investigate whether there are underlying mechanisms explaining the anti-inflammatory effect of clodronate and possibly involving hydrogen sulphide (HS).

Unsulfated biotechnological chondroitin by itself as well as in combination with high molecular weight hyaluronan improves the inflammation profile in osteoarthritis in vitro model.

Several studies suggest that inflammation has a pivotal role during the progression of osteoarthritis (OA) and cytokines have been identified as the main process mediators. This study aimed to explore the ability to modulate the main OA pro-inflammatory biomarkers of novel gels (H-HA/BC) based on high molecular weight hyaluronan (H-HA) and unsulfated biotechnological chondroitin (BC). For the first time, BC was tested also in combination with H-HA on human primary cells isolated from pathological knee joints.

The popliteomeniscal fascicles: from diagnosis to surgical repair: a systematic review of current literature.

Background: Popliteomeniscal fascicles (PMF) are considered the posterolateral meniscocapsular extensions which connect the lateral meniscus to the edge of the tibia. PMFs disruption leads to hypermobility of the lateral meniscus with pain and locking sensation. Recognition and treatment of PMFs tear remain very challenging.

Modified Zadek osteotomy without excision of the intratendinous calcific deposit is effective for the surgical treatment of calcific insertional Achilles tendinopathy.

Introduction: Nonoperative management of calcific insertional Achilles tendinopathy (CIAT) may fail in 10-30% of patients, and various operative procedures have been described to manage those.

Methods: A modified Zadek (dorsal closing wedge) calcaneal osteotomy, without removing the calcific deposits and without detaching the insertion of the Achilles tendon, was performed between November 2016 and December 2017 in 25 consecutive patients (mean age 53.5 years), who were followed for at least 2 years.

Combined medial patellofemoral and patellotibial reconstruction with soft tissue fixation in recurrent patellar dislocation.

Introduction: The medial patellofemoral and patellotibial ligaments (MPFL and MPTL) are the main passive restraints to lateral patellar translation. When nonoperative management of patellofemoral dislocations fails, surgical options can be considered to restore patellofemoral stability. Several reconstruction procedures of the MPFL with semitendinosus, gracilis, quadriceps tendon, and synthetic grafts have been described.

Dorsally Based Closing Wedge Osteotomy of the Calcaneus for Insertional Achilles Tendinopathy.

Background: Surgical management may be indicated for patients with insertional Achilles tendinopathy (IAT) after failure of nonoperative management, and various surgical techniques have been described.

Hypothesis: We present the technique and results of modified dorsal closing wedge calcaneal osteotomy, performed in a cohort of 28 consecutive patients. We hypothesized that this will be a safe procedure that can improve hindfoot pain and function for most patients who will return to preoperative daily life and sports activities.

Delayed (14-30 Days) Percutaneous Repair of Achilles Tendon Ruptures Offers Equally Good Results As Compared With Acute Repair.

Background: Minimally invasive repair of acute Achilles tendon ruptures has been performed for several years, resulting in reduced morbidity as compared with open repair.

Hypothesis: A minimally invasive technique can be used to manage Achilles tendon ruptures in patients presenting between 14 and 30 days from injury.

Study Design: Cohort study; Level of evidence, 3.

Ipsilateral free semitendinosus graft with interference screw fixation for surgical management of insertional acute Achilles tendon tears.

Introduction: Very distal tears of the Achilles tendon are uncommon, and poor quality tendinous tissue of the calcaneal stump can compromise healing. Little has been published about the characteristics and surgical management of such injuries. We present a surgical technique, developed by the senior author, to restore continuity of the gastrosoleus-Achilles tendon-calcaneus complex using a free ipsilateral semitendinosus graft, and clinical outcomes of a case series of 28 consecutive patients.

Knee septic arthritis caused by α-hemolytic Streptococcus in a patient with a recent history of knee arthroscopy: a case report.

Novel Hybrid Gels Made of High and Low Molecular Weight Hyaluronic Acid Induce Proliferation and Reduce Inflammation in an Osteoarthritis Model Based on Human Synoviocytes and Chondrocytes.

High molecular weight hyaluronan (H-HA) has a pivotal role in the maintenance of normal functions of synovial fluid and structure of the articular joint, but it has been shown that its concentration is reduced in patients affected by degenerative cartilage diseases, such as osteoarthritis (OA). The aim of this study was to investigate the anti-inflammatory effects and properties of hybrid cooperative complexes based on high and low molecular weight hyaluronan (HCC) compared to H-HA on human primary cells derived by pathological joints. In addition, the rheological behavior of HCC was evaluated in order to define their potential as viscosupplement gel in degenerated joints.
