Total knee arthroplasty in stiff knee compared with flexible knees
MUSCULOSKELETAL SURGERY, 2011This retrospective study was done to evaluate the results of total knee arthroplasty performed on 32 patients with stiff knee, having a preoperative arc of movement between 0° and 50° (average 30°). This group of patients were matched with a group of 32 flexible knees, randomly selected from the same cohort of patients who underwent knee arthroplasty ...

Knee Arthroscopy in the Setting of Knee Arthroplasty [PDF]
The Journal of Knee Surgery, 2016 Knee arthroplasty is an effective and reproducible way of treating advanced knee arthritis; however, results are not always favorable. Knee arthroscopy has been described in symptomatic knee arthroplasty, but opinion is divided over its utility. The purpose of this systematic review is to examine existing evidence supporting knee arthroscopy in the ...

Total Knee Arthroplasty in the Valgus Knee
Journal of the American Academy of Orthopaedic Surgeons, 2002The valgus knee presents a unique set of problems that must be addressed during total knee arthroplasty. Both bone and soft-tissue deformities complicate restoration of proper alignment, positioning of components, and attainment of joint stability.

Tibiofemoral forces determine polyethylene wear and affect the longevity of total knee prostheses. Previously, investigators relied on theoretic data from mathematical models to predict mechanical forces in the knee. Predictions of tibiofemoral forces are highly variable because of the complex interplay of the muscles involved in activities.

Total Knee Arthroplasty in Valgus Knees
Clinical Orthopaedics and Related Research, 1991One hundred thirty-four total knee arthroplasties in 98 patients with a valgus alignment were analyzed. Knees with a preoperative alignment of 10 degrees or greater anatomic valgus were believed suitable for inclusion. The average follow-up period in these patients was 4.5 years (range, two to ten years).

Knee stability in orthotic knee braces
The American Journal of Sports Medicine, 1984The ability of six commercially available orthotic knee braces to stabilize ligamentous injuries of the knee was evaluated using fresh cadaver specimens. Anterior, valgus, and rotational forces were applied to the intact knee, after the anterior cruciate and medial collateral ligaments were cut, and after application of the knee braces.

Knee Stability and Knee Ligament Injuries
JAMA: The Journal of the American Medical Association, 1975Controversy exists on the relationship of knee ligament stability to knee injuries. Subjective evaluation of joint tightness or looseness has been proposed as a criterion for prescribing selective corrective strengthening or stretching exercises. Biomechanical studies of knee ligament stability were performed on 401 college football players from 1969 ...

We present the case of a 90-year-old man with a swollen, painful knee and a history of paraffin injections. Radiography showed soft tissue streaky and nodular calcifications without erosions. MR imaging showed globular areas of low signal intensity on T1- and T2-weighted images which became even more hypointense on STIR sequences, and an infiltrative ...

BMJ, 2017 A 28 year old man was brought to hospital after a road traffic incident. He described hearing a “pop” as his right knee impacted against the dashboard at the time of collision, and he subsequently experienced extreme pain. On examination in the emergency department, his knee was swollen and tender, and range of movement was severely limited.

Knee biomechanics and total knee replacement
The Journal of Arthroplasty, 1986The biomechanics of the knee joint provide an important basis for the rationale in the design and selection of appropriate total knee arthroplasty. This article examines knee biomechanics in terms of patient function, prosthesis design, cruciate ligament retention, alignment, and fixation of the tibial component. While design and surgical technique for
