In older people, this give way or some unstable feeling can be injured during a fall. An MCL injury can be a partial or complete tear, or overstretching of the ligament. Knee ligament injuries are also referred to as sprains. It’s common to injure one of your cruciate ligaments (the two ligaments that cross in the middle of your knee which help to stabilise), or your meniscus (cartilage discs that help provide a cushion between your thigh and shin bone), at the same time as your MCL. Early management Elevating your ankle and leg will also assist in reducing the swelling.

  • Hip Conditioning Program

    Hip Conditioning Program

    Our knowledge of orthopaedics. Your best health. Prepared for: Prepared by: Hip Conditioning Program Purpose of Program _________________________________________________________________ After an injury or surgery, an exercise conditioning program will help you return to daily activities and enjoy a more active, healthy lifestyle. Following a well-structured conditioning program will also help you return to sports and other recreational activities. This is a general conditioning program that provides a wide range of exercises. To ensure that the program is safe and effective for you, it should be performed under your doctor’s supervision. Talk to your doctor or physical therapist about which exercises will best help you meet your rehabilitation goals. Strength: Strengthening the muscles that support your hip will help keep your hip joint stable. Keeping these muscles strong can relieve pain and prevent further injury. Flexibility: Stretching the muscles that you strengthen is important for restoring range of motion and preventing injury. Gently stretching after strengthening exercises can help reduce muscle soreness and keep your muscles long and flexible. Target Muscles: The muscle groups targeted in this conditioning program include: • Gluteus maximus (buttocks) • Adductors (inner thigh) • Gluteus medius (buttocks) • Abductors (outer thigh) • Hamstrings (back of thigh) • Tensor Fascia (outer thigh) • Piriformis (buttocks) Length of program: This hip conditioning program should be continued for 4 to 6 weeks, unless otherwise specified by your doctor or physical therapist. After your recovery, these exercises can be continued as a maintenance program for lifelong protection and health of your hips and thighs. Performing the exercises two to three days a week will maintain strength and range of motion in your hips and thighs.

  • Anterior (Cranial) Cruciate Ligament Rupture

    Anterior (Cranial) Cruciate Ligament Rupture

    Cranial Cruciate Ligament Rupture in Dogs The cruciate ligaments are tough fibrous bands that connect the distal femur (thigh bone) to the proximal tibia (shin bone). Two cruciate ligaments, the cranial (anterior) and the posterior cruciate ligaments, are found in the knee joint of dogs and cats (and most other domestic animals). These ligaments work like a hinge joint in the knee and are responsible for providing anterior-posterior stability to the knee joint. Normal Knee Joint of a Dog Rupture of the cranial cruciate ligament is rare in cats. It occurs frequently in overweight, middle- and older-aged dogs. Certain dog breeds appear to be predisposed to cranial cruciate ligament rupture. Most commonly, the cocker spaniel and rottweiler are affected. The miniature and toy poodle, Lhasa apso, bichon frise, golden retriever, Labrador retriever, German shepherd and mastiff seem to be predisposed as well. The normal knee joint works as a hinge, keeping the knee stable as it bends. Tearing of the cranial cruciate ligament causes instability of the knee joint and it ceases to function properly. Most cranial cruciate ligament tears in dogs occur gradually, resulting in a low-level lameness that may or nay not improve over time. After the ligament tears, inflammation occurs within the joint. Continued use and weight bearing by the dog often causes the ligament to rupture completely. Dogs that rupture one cruciate ligament have about a fifty percent chance of rupturing the other. Normal Knee Joint of a Dog Rupture of the cranial cruciate ligament in dogs can also occur acutely. Similar to cranial cruciate ligament rupture in humans, resulting from athletic injuries to the knee, dogs can tear this ligament by jumping up to catch a ball or Frisbee or by jumping out of a truck or off a porch.

    The Ligament Anatomy of the Deltoid Complex of the Ankle: a Qualitative and Quantitative Anatomical Study

    e62(1) COPYRIGHT Ó 2014 BY THE JOURNAL OF BONE AND JOINT SURGERY,INCORPORATED The Ligament Anatomy of the Deltoid Complex of the Ankle: A Qualitative and Quantitative Anatomical Study Kevin J. Campbell, BS, Max P. Michalski, MSc, Katharine J. Wilson, MSc, Mary T. Goldsmith, MS, Coen A. Wijdicks, PhD, Robert F. LaPrade, PhD, MD, and Thomas O. Clanton, MD Investigation performed at the Department of Biomedical Engineering, Steadman Philippon Research Institute, and the Steadman Clinic, Vail, Colorado Background: The deltoid ligament has both superficial and deep layers and consists of up to six ligamentous bands. The prevalence of the individual bands is variable, and no consensus as to which bands are constant or variable exists. Although other studies have looked at the variance in the deltoid anatomy, none have quantified the distance to relevant osseous landmarks. Methods: The deltoid ligaments from fourteen non-paired, fresh-frozen cadaveric specimens were isolated and the ligamentous bands were identified. The lengths, footprint areas, orientations, and distances from relevant osseous landmarks were measured with a three-dimensional coordinate measurement device. Results: In all specimens, the tibionavicular, tibiospring, and deep posterior tibiotalar ligaments were identified. Three additional bands were variable in our specimen cohort: the tibiocalcaneal, superficial posterior tibiotalar, and deep anterior tibiotalar ligaments. The deep posterior tibiotalar ligament was the largest band of the deltoid ligament. The origins from the distal center of the intercollicular groove were 16.1 mm (95% confidence interval, 14.7 to 17.5 mm) for the tibionavicular ligament, 13.1 mm (95% confidence interval, 11.1 to 15.1 mm) for the tibiospring ligament, and 7.6 mm (95% confidence interval, 6.7 to 8.5 mm) for the deep posterior tibiotalar ligament.

No further reproduction is authorized without written permission from SAGE Publications (UK and US). This version of the document is not the version of record. Figures and/or pictures may be missing from this format of the document.*** Abstract: Background Varus-valgus (LAXVV) and internal-external (LAXIER) rotational knee laxity have received attention as potential contributing factors in anterior cruciate ligament injury. This study compared persons with above-and below-average LAXVV and LAXIER values on hip and knee neuromechanics during drop jump landings. Hypothesis People with greater LAXVV and LAXIER values will have greater challenges controlling frontal and transverse plane knee motions, as evidenced by greater joint excursions, joint moments, and muscle activation levels during the landing phase. Study Design Descriptive laboratory study. Methods Recreationally active participants (52 women and 44 men) between 18 and 30 years old were measured for LAXVV and LAXIER and for their muscle activation and transverse and frontal plane hip and knee kinetics and kinematics during the initial landing phase of a drop jump. The mean value was obtained for each sex, and those with above-average values on LAXVV and LAXIER (LAXHIGH = 17 women, 16 men) were compared with those with below-average values (LAXLOW = 18 women, 17 men).
  • Acetabular Labral Tears with Underlying Chondromalacia: a Possible Association with High-Level Running

    Acetabular Labral Tears with Underlying Chondromalacia: a Possible Association with High-Level Running

    Acetabular Labral Tears With Underlying Chondromalacia: A Possible Association With High-Level Running Carlos A. Guanche, M.D., and Robby S. Sikka, B.A. Purpose: The use of hip arthroscopy has helped delineate intra-articular pathology and has enabled clinicians to further elucidate the factors responsible for injuries, such as running. The subtle development of degenerative changes may be a result of repetitive impact loading associated with this sport. This study presents a population of runners with common pathologic acetabular changes. Type of Study: Case series. Methods: Eight high-level runners with an average age of 36 years (range, 19 to 45 years) were seen for complaints of increasing hip pain with running without any history of macrotrauma. All of the patients had either run several marathons (4), were triathletes (1), Olympic middle distance runners (1), or had run more than 10 miles per week for longer than 5 years (2). Plain radiographic analysis revealed no degenerative changes and an average center-edge (CE) angle of 36.7° (range, 28° to 44°). Results: All patients underwent hip arthroscopy with labral debridement. In 6 patients (75%), a chondral injury of the acetabular cartilage underlying the labral tear was noted. In addition, 3 patients had ligamentum teres disruptions. Conclusions: It is possible that the development of these tears is the result of subtle instability, which may be exacerbated by running, eventually leading to labral tearing and possible ligamentum teres disruption. While perhaps con- currently, subtle acetabular dysplasia may play a role. Although this study does not confirm an association between running and the development of labral tears or chondral lesions in the hip, it certainly questions whether there is an injury pattern common to this population, a “runner’s hip.” Level of Evidence: Level IV.
