The posterior cruciate ligament (PCL)-based multiple ligament injury, or dislocated knee, is often part of a multisystem injury complex that not only includes the knee ligaments, but may also include blood vessels, skin, nerves, fractures, and other organ system trauma. These factors must be considered in the scope of treating this complex knee injury. These complex knee ligament injuries can result in significant functional instability for the affected individual. This article will discuss multiple ligament knee injury evaluation, treatment, and special considerations in the pediatric and adolescent population...

The infiltration of local anesthetic has been shown to reduce postoperative pain in knee arthroscopy. Several studies have shown that the addition of agents such as magnesium and nonsteroidal antiinflammatory drugs (NSAIDs) result in an increased time to first analgesia and overall reduction in pain. The aim of this systematic review and meta-analysis was to determine whether the addition of an α-2 agonist (A2A) to intra-articular local anesthetic, results in a reduction in postoperative pain. Four major databases were systematically searched for relevant randomized controlled trials (RCTs) up to July 2017...

The use of tranexamic acid (TXA) in total knee arthroplasty (TKA) has become common practice. Recent literature has demonstrated a reduction in postoperative knee swelling and drain output while using TXA. Our purpose is to analyze the range of motion (ROM) following TKA in patients who received TXA compared with a control group. We hypothesize that patients treated with TXA will have improved early postoperative ROM when compared with controls. A retrospective chart review was performed for patients who underwent TKA from 2010 to 2012 performed by a single orthopaedic surgeon...

Injuries about the proximal tibia are quite common in children. Understanding the mechanisms of injury and treatment strategies is imperative for practitioners caring for these patients. Similarly, appreciating the anatomy of the proximal tibia and the adjacent neurovascular structures can assist a practitioner in recognizing the potential associated risks following fracture. Patients with injuries about the proximal tibia require long-term follow-up, and knowledge of the natural history of these fractures is imperative...

Perioperative care of the total knee arthroplasty (TKA) patient has evolved considerably over the past decade. Among the changes driving this evolution toward shorter hospitalization and accelerated rehabilitation have been regional anesthesia, peripheral nerve blockade, and multimodal analgesia protocols. These complementary techniques are increasingly supported by scientific evidence, though considerable uncertainty persists regarding the optimal combination of strategies. Continued refinement of technique and critical evaluation is trending toward greater characterization of the comparative effectiveness of myriad options...

Venous thromboembolic disease (VTED) is a major cause of morbidity and mortality after total knee arthroplasty (TKA). Current VTED prophylaxis protocols consist of early mobilization, mechanical compression devices, and pharmacologic agents. Venous phasic flow-regulated below-knee devices are generally favored, but the optimal duration and method of mechanical prophylaxis is unknown. Risk stratification models have been developed to guide pharmacologic prophylaxis. For patients with standard VTED risk profile, aspirin has become increasingly popular...

Fractures of the tibial spine are estimated to occur in 3 per 100,000 children annually, but account for 2 to 5% of pediatric knee injuries with effusion. Although these fractures were historically associated with bicycle accidents, the surge of organized youth sports in recent decades has brought renewed attention to this injury. While minimally displaced fractures can be treated nonoperatively, several techniques have been described for fixation of displaced or comminuted fractures. Sequelae of this injury can include arthrofibrosis, knee instability, and nonunion...

Medial patellofemoral ligament (MPFL) reconstruction is a satisfactory technique for patellar instability, and the anatomical double bundle variant is recommended for better clinical results. However, long-term outcomes are still uncharacterized. This study aimed to assess the effectiveness of double bundle reconstruction of the MPFL for patellar instability by means of established scores. A total of 68 patients with chronic patellar instability who underwent surgery from May 2005 to February 2010 were included prospectively...

Inconsistent data has been reported on the effect of the femoral posterior condyle offset (PCO) on the maximal knee flexion after total knee arthroplasty (TKA). This study investigated the relationship between the postoperative changes of the PCO and the changes of maximal knee flexion after a cruciate retaining (CR) TKA. Nine patients with medial osteoarthritis (OA) in one knee were investigated. Before operation, each index knee was magnetic resonance imaging (MRI) scanned for construction of a three-dimensional (3D) knee model...

The true value of use of patient-specific instrumentation (PSI) systems by inexperienced surgeons during their learning curve to improve the clinical and radiographic outcome of unicompartmental knee arthroplasty (UKA) has not been previously studied. Fifty patients with a mean age of 64.3 years undergoing surgery for Oxford UKA were prospectively divided into two groups. Twenty-five patients were operated on by a surgeon with no prior experience in UKA using a PSI system and the other 25 patients by an experienced surgeon using a conventional procedure...

Due to the paucity of evidence, this study was conducted to evaluate: (1) unique characteristics of multiple sclerosis (MS) patients and (2) short-term clinical outcomes, of primary total knee arthroplasty (TKA) in patients with MS (MS-TKA) compared with matched non-MS patients. MS patients who underwent TKA were identified using the Nationwide Inpatient Sample (NIS) database. The study sample consisted of 10,884 patients with MS and 56,45,227 control cohort. Various patient factors were compared. To control for potential confounders, with the use of propensity scores, MS-TKA patients were matched (1:3) to non-MS-TKA patients and regression analyses were performed to compare perioperative complications, length of stay (LOS), and discharge dispositions...

Low doses of corticosteroids have been proved to be effective in decreasing the inflammatory cytokines and relieving the pain. However, the optimal dosage of corticosteroids in total knee arthroplasty (TKA) is undetermined. A total of 103 patients were randomly divided into three groups. Group A containing 32 patients received normal saline. Group B including 36 patients used two doses of 100 mg hydrocortisone, given 2 hours before and 8 hours after surgery. Group C involving 35 patients received four doses of 100 mg hydrocortisone, 8 hours apart...

Unicompartmental knee arthroplasty (UKA) is a bone conserving and ligament-sparing procedure that reliably restores normal knee kinematics and function for arthritis limited either to the medial or the lateral compartment of the knee. Although there is enough evidence to demonstrate that the UKA offers good medium to long-term success given the correct patient selection, prosthesis design, and implantation technique, there are several reports to suggest inferior survival rates in comparison with the total knee arthroplasty (TKA)...

A new design of the so-called "guided-motion" total knee arthroplasty (TKA) is expected to produce normal-like kinematics. The implant behaves strictly as a mechanically constraint-guided motion system. However, no previous reports have demonstrated the most appropriate surgical technique or soft-tissue balance that would reproduce ideal kinematics. The purpose of this study was to clarify the relationship between soft-tissue balance and the intraoperative kinematics of guided-motion TKA. In this study, intraoperative kinematics of 95 patients whose TKA was performed with a guided-motion prosthesis (Journey II BCS Smith and Nephew) were measured using the computed tomography (CT)-free navigation system...

The purpose of this study was to evaluate the clinical outcomes after arthroscopic management of irreducible posterolateral knee dislocation. Twenty-one patients with irreducible posterolateral knee dislocation were treated in our institution from January 2009 to May 2014. Inclusion criteria were as follows: (1) patients who underwent one-stage arthroscopic reduction combined with multiligament reconstruction or repair and (2) patients with a minimum 2-year follow-up. Knee stability was assessed using physical examination and side-to-side differences (SSD) determined with a KT-1000 arthrometer and Telos stress device...

Despite the overall successful outcomes following primary total knee arthroplasty (TKA) and the concept that a well-balanced TKA yields a more successful result, concerns still remain in the reported literature regarding the patellofemoral joint. Diminished outcomes have been associated with poorly balanced or placed patella implants. The effect of different techniques to achieve flexion-extension balance and the use of posterior stabilized (PS) versus cruciate retaining (CR) implant designs on patellofemoral balancing has not been previously studied...

Articular defects are a major problem with few effective treatment options. Osteochondral allograft (OCA) transplantation can be an effective treatment; however, lack of OCA bone integration can cause failure. This controlled laboratory study was designed to compare clinically applicable methods for marrow element removal and enhanced delivery of bone marrow aspirate concentrate (BMC) to OCA bone. We hypothesized that compressed carbon dioxide (CO2 ) treatment of OCA bone would result in significantly better marrow element removal, significantly more retention and distribution of viable osteoprogenitor cells, and significantly higher osteoinductive protein elution from OCAs compared with other preimplantation treatments...
