BACKGROUND: Mechanical loading during exercise has been shown to promote tissue remodeling. Safe and accessible exercise may be beneficial to populations at risk of diminished bone and joint health. We examined the effect of drop height and instruction on knee loading during a drop-landing task and proposed a task that makes use of drop heights that may be appropriate for rehabilitation purposes and functional in daily life to examine transient knee joint loads. METHODS: Twenty males (22...

We present a case of a successful bilateral leg replantation in a 3-month-old baby after a knee-level crush amputation with the loss of both knee joints. The legs were replanted after 4 hours of warm and an additional 2.5 and 3.5 hours of cold ischemia time. Both legs show motor and sensory reinnervation, without additional procedures performed on the right leg, and after a nerve reconstruction with cadaveric allografts on the left leg. Both replanted legs exhibit excellent bony and soft tissue growth. Two years after the injury, the patient is progressing well with rehabilitation, with favourable odds of having knee reconstructions performed at a later age...

Severe burn injuries are associated with hypermetabolic response and increased catabolism. These lead to a vast loss of muscle mass and reduced muscle strength and function. Therefore, the aim of this study is to determine the impact of severe burn injuries on lower-limb muscular strength, balance, and mobility level in adults. Forty burned adults with burned TBSA (burned TBSA) ≥40% participated in this study. The peak torque and total work of quadriceps and knee flexors were calculated at 150°/sec using Biodex isokinetic dynamometer...

BACKGROUND AND AIMS: Pain reduction is important for rehabilitation after total knee arthroplasty. Intra- and peri-articular infiltration with local anesthetics may be an alternative to commonly used locoregional techniques. Adding pregabalin orally and s-ketamine intravenously may further reduce postoperative pain. MATERIAL AND METHODS: This prospective, randomized, double-blind, placebo-controlled study compared two methods of perioperative analgesia. Control patients received a standardized multimodal postoperative analgesic regime of paracetamol, diclofenac, and piritramide-patient-controlled analgesia, including ropivacaine knee infiltration during surgery...

OBJECTIVE: Fear of reinjury is associated with cessation of sport after anterior cruciate ligament (ACL) reconstruction despite normal postoperative knee function. The objective of this study is to describe factors informing athletes' experience of fear of reinjury post ACL reconstruction, in athletes who cited fear as the sole reason for not returning to their pre-injury level of sport. DESIGN: Mixed-methods study design of qualitative and a preliminary quantitative component...

BACKGROUND: Wound closure is key to prevent infection, facilitate immediate rehabilitation, and improve efficiency of total knee arthroplasty (TKA). Continuous knotless suturing with barbed suture can potentially save time and distribute tension more evenly. However, its role in TKA in terms of cost-effectiveness and wound complications is not clear. This study aims at comparing barbed and traditional sutures' wound closure time and cost in primary TKA. METHODS: One hundred nine knees were randomized into either barbed or traditional group...

BACKGROUND AND PURPOSE: Total joint arthroplasty (TJA) is an effective and successful treatment of osteoarthritis of the hip and knee as quantified by several measures, such as pain relief, improved walking, improved self-care, functions, and increased quality of life. Data are lacking as to the definition of a satisfactory functional gain in a postacute setting and identifying the characteristics of older patients with TJA who may achieve that gain. Our aim was to characterize patients who may achieve a satisfactory functional gain in a postacute rehabilitation setting following TJA...

Endocannabinoids are a class of lipid mediators involved in a wide range of physiological pathways including pain perception, and immunological defences. In particular, the involvement of endocannabinoids in bone metabolism and bone resorption has recently been studied. Moreover, one study on total knee arthroplasty describes the probable role of endocannabinoids in pain perception after surgery. The aim of the present study was to evaluate variations of endocannabinoid concentrations in patients undergoing total hip or total knee arthroplasty before and after surgery...

REVIEW
Bart Dingenen, Alli Gokeler
Athletes who have sustained an anterior cruciate ligament (ACL) injury often opt for an ACL reconstruction (ACLR) with the goal and expectation to resume sports. Unfortunately, the proportion of athletes successfully returning to sport is relatively low, while the rate of second ACL injury has been reported to exceed 20% after clearance to return to sport, especially within younger athletic populations. Despite the development of return-to-sport guidelines over recent years, there are still more questions than answers on the most optimal return-to-sport criteria after ACLR...

REVIEW
Allston Julius Stubbs, Halis Atil Atilla
BACKGROUND: Despite the rapid advancement of imaging and arthroscopic techniques about the hip joint, missed diagnoses are still common. As a deep joint and compared to the shoulder and knee joints, localization of hip symptoms is difficult. Hip pathology is not easily isolated and is often related to intra and extra-articular abnormalities. In light of these diagnostic challenges, we recommend an algorithmic approach to effectively diagnoses and treat hip pain. METHODS: In this review, hip pain is evaluated from diagnosis to treatment in a clear decision model...

INTRODUCTION: Isolated injuries to the posterolateral corner of the knee are a rare and commonly missed injury associated with athletic trauma, motor vehicle accidents, and falls. Delayed or missed diagnoses can negatively impact patient prognosis, contributing to residual instability, chronic pain, and failure of surgical repair to other ligaments.

Gluteal muscle contracture (GMC), a debilitating disease, exists all over the globe but it is much more prevalent in China. Patients typically present with abduction and external rotation of the hip and are unable to bring both the knees together while squatting. Multiple etiologies have been postulated, the commonest being repeated intramuscular injection into the buttocks. The disease is diagnosed primarily by clinical features but radiological features are necessary for the exclusion of other pathological conditions...

BACKGROUND: Results of anterior cruciate ligament (ACL) reconstruction are traditionally excellent in younger and nonarthritic patients. During the past few decades, people older than 60 years have become more active than ever, with more demanding physical lifestyles. An increase also has been noted in active patients with diagnosed ACL injuries. More patients are requesting treatment for ACL deficiency in hopes of returning to preinjury levels of activity. PURPOSE: The aims of this study were to evaluate the results of ACL reconstruction in patients older than 60 years in terms of functional recovery, return to sports, and postoperative incidence of osteoarthritis and to compare their results with published results of different age groups...

Successful posterior cruciate ligament (PCL) reconstruction surgery results from identification and treatment of associated pathology such as posterolateral instability, posteromedial instability, and lower extremity malalignment. The use of strong graft material, properly placed tunnels to as closely as possible approximate the PCL insertion sites, and minimization of graft bending also enhance the probability of PCL reconstruction success. In addition, mechanical graft tensioning, primary and back-up PCL graft fixation, and the appropriate postoperative rehabilitation program are also necessary ingredients for PCL reconstruction success...

We developed a method to investigate feed-forward and feedback movement control during a weight bearing visuomotor knee tracking task. We hypothesized that a systematic increase in speed and resistance would show a linear decrease in movement accuracy, while unexpected perturbations would induce a velocity-dependent decrease in movement accuracy. We determined the effects of manipulating the speed, resistance, and unexpected events on error during a functional weight bearing task. Our long term objective is to benchmark neuromuscular control performance across various groups based on age, injury, disease, rehabilitation status, and/or training...

Total knee arthroplasty (TKA) without soft tissue balance can create a balanced knee to a mechanical axis of near neutral with bone cuts, and remove osteophytes thoroughly. In this study, the authors present detailed steps for performing TKA. The attached video demonstrates the TKA procedure. The patient is a 77-year-old man who had suffered from knee pain for 12 years. Physical examination showed the Apley test to be positive and that the range of motion (ROM) decreased. An X-ray filmed at the positive lateral of the knee joint and the double lower extremity revealed a progression of degenerative osteoarthritis with genu varum...
