Soft tissue defect coverage has always been a challenge for the orthopaedic surgeon. Over the last decades the surgery of flaps has completely changed the prognosis for large defects. The purpose of this study is to retrospectively review our experience with the gastrocnemius muscle as pedicled local flaps for reconstruction of knee and upper third of the tibia soft tissue defects.

Introduction: Fractures of the proximal tibia are high velocity injuries often associated with soft tissue compromise especially in the type V and VI fracture patterns. Dual plating is the preferred treatment option for these injuries but not in a setting where there is extensive soft tissue injury, as this can lead to problems with wound healing. The aim of this study was to evaluate the functional outcome following hybrid external fixation in the management of Schatzkers type V and VI fractures. Read More

Introduction: Advances in the care of soft-tissue tumors, including imaging capabilities and adjuvant radiation therapy, have broadened the indications and opportunities to pursue surgical limb salvage. However, peripheral nerve involvement and femoral nerve resection can still result in devastating functional outcomes. Nerve transfers offer a versatile solution to restore nerve function following tumor resection. Read More

Background: Chondrons are composed of chondrocytes and the surrounding pericellular matrix (PCM) and function to enhance chondrocyte-mediated cartilage tissue engineering. This study aimed at investigating the potential effect of combined chondrocytes with chondrons on the production of proteoglycan and collagen-II (Col-2) and the repair of defective knee cartilage in rabbits.

Methods: Chondrocytes and chondrons were isolated from the knee cartilage of rabbits, and cultured alone or co-cultured for varying periods in vitro. Read More

Inside-out meniscal repair is considered the gold standard for reparable tears of the medial and lateral menisci despite the recent popularity of all-inside devices. Accurate suture passage is required to perform a stable repair as well as to prevent inadvertent neurovascular injury from the suture needles. Placement of a deep soft-tissue retractor is necessary to identify and retrieve these needles prior to tying the sutures. Read More

Many different autografts are available for anterior cruciate ligament reconstruction. Although patellar tendon graft and hamstrings are most commonly used, quadriceps tendon with or without a bone plug is gaining popularity. Preliminary evidence suggests that quad tendon without a bone plug performs at least as well as with a plug, although more comparative information is needed. Read More

Introduction: Septic arthritis is an orthopedic emergency that requires rapid diagnosis and treatment. It is typically caused by occult bacteremia which allows bacteria to seed the joint or local invasion of a soft tissue infection. Most cases of septic arthritis are caused by gram-positive bacteria, with the most common culprit being Staphylococcus Aureus. Read More

Department of Orthopedic Surgery, Smarton Hospital, Bucheon, Korea.

Background: Patellar tendon rupture is a relatively rare injury that usually requires surgical treatment. The optimal therapeutic strategy is still controversial, especially when either concomitant patellar tendon infection or soft tissue infection surrounds the patellar tendon. Until recently, most reported reconstruction methods are extensive and difficult to apply because of the poor condition of the soft tissue surrounding the patellar tendon. Read More

Addition To Orthopedic Literature: Posterolateral knee dislocations are extremely rare and generally require open reduction; however, we were able to provide closed reduction by reproducing mechanism of injury with a technique described in the literature. This is the second reported case of such accomplishment.

Introduction: Posterolateral knee dislocation is the most common form of "irreducible" knee dislocations. Read More

The pivot shift and Lachman examinations are "teammates" with complementary but distinct roles in the successful diagnosis and treatment of anterior cruciate ligament rupture and injury to the surrounding soft-tissue envelope of the knee. The Lachman test measures anterior tibial translation in response to an applied anterior tibial load. This test assesses the integrity of the native or reconstructed anterior cruciate ligament and the secondary medial restraints including the medial meniscus and medial collateral ligament. Read More

The purpose of this multicenter, retrospective, observational study was to investigate the association between intraoperative component positioning and soft tissue balancing, as reported by robotic technology for a cohort of patients who received robotic arm-assisted lateral unicompartmental knee arthroplasty (UKA) as well as short-term clinical follow-up of these patients. Between 2013 and 2016, 78 patients (79 knees) underwent robotic arm-assisted lateral UKAs at two centers. Pre- and postoperatively, patients were administered the Knee Injury and Osteoarthritis Score (KOOS) and the Forgotten Joint Score-12 (FJS-12). Read More

This study aimed to explore the association between hamstring strength, age and lower limb soft tissue injury history and subsequent hamstring injury among Australian Football League (AFL) players. This prospective cohort study recruited 125 players from three professional AFL teams. Eccentric knee flexor strength was assessed while performing the Nordic hamstring exercise in pre-season, and injury data were collected retrospectively (hamstring, groin, calf, quadriceps and knee), and prospectively (hamstring injuries) for one AFL playing season.

The term "sideswipe injury" has become synonymous and used interchangeably with the term "traffic elbow." However, with the continuous rise in the use of the tricycle as a means of public transportation in some developing countries, a rise in sideswipe injuries of various severities is being experienced. We report a case of sideswipe injury to the left knee region of a 45-year-old female who was a passenger in the backseat of a tricycle. Read More

Twenty men with spinal cord injury (SCI) were randomized into two 16-week intervention groups receiving testosterone treatment (TT) or TT combined with resistance training (TT + RT). TT + RT appears to hold the potential to reverse or slow down bone loss following SCI if provided over a longer period.

Introduction: Persons with SCI experience bone loss below the level of injury. Read More

Patellofemoral instability is a common pathology especially in the adolescent female population. Prompt diagnosis and management is critical to prevent future episodes of instability as well as to reduce the risk of cartilaginous injury to the patellofemoral articular surface. Initial management of a first-time patellar dislocation has historically been nonsurgical; however, the presence of intra-articular loose bodies or osseocartilaginous injury may require surgical intervention.

South West London Elective Orthopaedic Centre , Epsom, UK.

Introduction: An ever-increasing number of clinics are offering purportedly 'regenerative' stem-cell treatments, although cell-based therapies may not primarily act as stem cells and have shown the ability to regenerate end-target tissues in some clinical studies only. We aim to systematically review the evidence for their use in soft-tissue sports injuries of the knee.

Areas Covered: A search for articles pertaining to the use of preparations of, or containing, mesenchymal stem cells (MSCs) in human subjects in sports knee injuries yielded 14 relevant results for inclusion after screening: 7 used cultured MSCs, 5 bone marrow concentrate (BMC), and the remaining 2 evaluated stromal vascular fraction (SVF) and tenocyte-like-cells.

Background: The association between activity level after anterior cruciate ligament (ACL) reconstruction (ACLR) and development of posttraumatic osteoarthritis (PTOA) remains unclear. This study investigated the relationship of patient-reported outcomes and progressive cartilage degenerative changes at 3 years after ACLR.

Hypothesis: Higher activity levels, as measured by Marx scores, are significantly correlated with early cartilage degeneration after ACLR. Read More
