Effect of Periarticular Corticosteroid Injections During Total Knee Arthroplasty
Journal of Bone and Joint Surgery, 11/03/2009

Christensen CP et al. – The periarticular injection of a corticosteroid may reduce the length of the hospital stay following total knee arthroplasty, but it does not appear to improve pain relief, motion, or ... at the site of the prosthetic joint, the authors cannot rule it out either, which raises concern regarding the role of corticosteroids in perioperative pain management following total knee arthroplasty.

ACL prosthesis: any promise for the future
Knee Surgery, Sports Traumatology, Arthroscopy, 11/18/2009

Bernardino S – Prosthetics are not widely used today in ACL reconstruction, and autogenous tissue grafts remain the gold standard used by the majority of surgeons. Perhaps development of resorbable, tissue inducing and cell–seeded biomaterials ... reconstructed ACL. Tissue ingrowth scaffolds and ligament augmentation devices require further refinement to provide effective mechanical support while avoiding stress shielding of the host tissue. [more...]

Anterior knee pain and cold knees: A possible association in women
The Knee, 11/03/2009

Selfe J et al. – Women with cold knees had a significantly smaller patellar skin fold, lower levels of activity and worse scores on the MFIQ, there also appeared to be an association with a traumatic onset. Women with cold knees were ... their knees and they preferred a hot water bottle compared to an ice–pack on their knee; there was also a trend towards having to wear extra tights/long johns in the winter. This study has helped to define a clinical profile for a group of females with AKP and cold knees. This group appears to ... demonstrate a mild form of Reflex Sympathetic Dystrophy. [more...]

The Potential Role of Prophylactic/Functional Knee Bracing in Preventing Knee Ligament Injury
Sports Medicine, 10/26/2009

Rishiraj N et al. – The review of subjective and some objective publications suggests that a functional knee brace may offer stability to an ACL–deficient knee joint; however, research is limited on the use of a knee brace for ... prophylactic use in non–injured athletes. The limited research could be a result of fear of performance hindrance that has led to poor knee brace compliance. [more...]

Novel Approach for Peripheral Subcutaneous Field Stimulation for the Treatment of Severe, Chronic Knee Joint Pain After Total Knee Arthroplasty
Neuromodulation, 11/23/2009

McRoberts WP et al. – Introduction of a peripheral subcutaneous field stimulation directly to the painful knee area is a novel and simple procedure that was extremely effective ... treatment of chronic intractable knee pain following total knee arthroplasty. The periarticular approach has several advantages, including only small incisions over the lateral and medial knee, proximal thigh and abdomen resulting in minimal strain on the lead array with flexion and extension ... this system.

Knee Extension and Flexion Weakness in People With Knee Osteoarthritis: Is Antagonist Co-contraction a Factor
Journal of Orthopaedic & Sports Physical Therapy, 10/26/2009

Heiden TL et al. – The results demonstrate that the reduction in isometric extension strength, measured with a 90° knee flexion angle, in subjects with knee OA is not associated with ... increased antagonist co–contraction. [more...]

Knee Extension and Flexion Weakness in People With Knee Osteoarthritis: Is Antagonist Cocontraction a Factor
Journal of Orthopaedic & Sports Physical Therapy, 11/02/2009

The LISS plate treatment of supracondylar fractures above a total knee replacement
Acta Orthopaedica Belgica, 11/05/2009

Norrish AR et al. – The aim of this study was to assess the outcome of periprosthetic fractures above a total knee arthroplasty treated by LISS plate fixation. The primary outcome measure was the radiological union. Secondary outcome measures were knee function using ... Oxford Knee Score, and quality of life using the SF–12 questionnaire. Over a 4–year period authors treated 16 supracondylar periprosthetic fractures with a LISS plate in 15 patients. Eleven patients were followed up for an average of 8 months. No statistically significant differences ... in the Oxford knee scores or quality of life scores between the two groups. This data suggest favourable outcomes after LISS plate fixation of supracondylar periprosthetic femoral fractures above total knee replacement. [more...]

Cartilage loss occurs in the same subregions as subchondral bone attrition: A within-knee subregion-matched approach from the multicenter osteoarthritis study
Arthritis Care and Research, 11/05/2009

Neogi T et al. SBA is strongly associated with cartilage loss within the same subregion of a knee. SBA may directly influence overlying cartilage loss or serve ... or are at high risk for knee OA At baseline and 30 months, participants' knee MRIs graded using the Whole-Organ Magnetic Resonance Imaging Score in 10 subregions of the tibiofemoral joint for cartilage morphology and SBA Analyses conducted within a knee to eliminate between-person ... controls) matched case-control approach with 10 subregions of person's knee forming matched set Cases within a knee were defined as subregions with cartilage loss, while controls were subregions in that same knee without cartilage loss Evaluated the association of cartilage loss over ... knee using conditional logistic regression Results SBA associated with odds ratio of 7.5 (95% confidence interval 5.6-9.9) for cartilage loss in same subregion compared with subregions without any baseline SBA in sample of 459 knees 64% women, mean age 63 y [more...]

Orthopedic management of spina bifida. Part I: hip, knee, and rotational deformities
Journal of Children's Orthopaedics, 10/28/2009

Swaroop VT et al. – Children with spina bifida develop a wide variety of congenital and acquired orthopedic deformities. Among these are hip deformities such as contracture, subluxation, or dislocation. Patients may also have problems with the knee joint ... such as knee flexion or extension contracture, knee valgus deformity, or late knee instability and pain. In addition, rotational deformities of the lower extremities, either internal or external torsion, are common as well. [more...]
