TLDR
The KOOS is a valid, reliable and responsive self-administered instrument that can be used for short-term and long-term follow-up of several types of knee injury including osteoarthritis.
Abstract
The Knee injury and Osteoarthritis Outcome Score (KOOS) was developed as an extension of the WOMAC Osteoarthritis Index with the purpose of evaluating short-term and long-term symptoms and function in subjects with knee injury and osteoarthritis. The KOOS holds five separately scored subscales: Pain, other Symptoms, Function in daily living (ADL), Function in Sport and Recreation (Sport/Rec), and knee-related Quality of Life (QOL). The KOOS has been validated for several orthopaedic interventions such as anterior cruciate ligament reconstruction, meniscectomy and total knee replacement. In addition the instrument has been used to evaluate physical therapy, nutritional supplementation and glucosamine supplementation. The effect size is generally largest for the subscale QOL followed by the subscale Pain. The KOOS is a valid, reliable and responsive self-administered instrument that can be used for short-term and long-term follow-up of several types of knee injury including osteoarthritis. The measure is relatively new and further use of the instrument will add knowledge and suggest areas that need to be further explored and improved.

Postural stability during the transition from double-leg stance to single-leg stance in anterior cruciate ligament injured subjects.

TL;DR: The anterior cruciate ligament injured group showed postural stability deficits during the single-leg stance phase compared to the non-injured control group in the eyes closed condition.

Malleolar fractures and their ligamentous injury equivalents have similar outcomes in supination-external rotation type IV fractures of the ankle treated by anatomical internal fixation

TL;DR: In this population of strictly defined SER IV ankle injuries, the presence of a malleolar fracture was not associated with a significantly worse clinical outcome than its ligamentous injury counterpart and other factors inherent to the injury and treatment may play a more important role in predicting outcome.

How much hamstring graft needs to be in the femoral tunnel? A MOON cohort study

TL;DR: It is hypothesized that no difference in two-year patient-reported outcomes or failure risk exists based on the amount of graft in the femoral tunnel, and variation of the length of hamstring autograft in the Femoral tunnel between 14 and 35 mm does not predict KOOS or IKDC scores at 2 years postoperative.

A randomized controlled trial comparing tibial migration of the ATTUNE cemented cruciate-retaining knee prosthesis with the PFC-sigma design.

TL;DR: In the first two postoperative years the initial version of the ATTUNE tibial component was not inferior with respect to overall migration, although it showed relatively more backwards tilting and radiolucent lines at the implant-cement interface than the PFC-sigma.

Validation study of WOMAC: a health status instrument for measuring clinically important patient relevant outcomes to antirheumatic drug therapy in patients with osteoarthritis of the hip or knee.

TL;DR: WOMAC is a disease-specific purpose built high performance instrument for evaluative research in osteoarthritis clinical trials and fulfil conventional criteria for face, content and construct validity, reliability, responsiveness and relative efficiency.

Rating systems in the evaluation of knee ligament injuries.

TL;DR: A new activity grading scale, where work and sport activities were graded numerically, was constructed as complement to the functional score, showing that the symptom-related score gave a more differentiated picture of the disability.

Knee Injury and Osteoarthritis Outcome Score (KOOS)--development of a self-administered outcome measure

TL;DR: The KOOS proved reliable, responsive to surgery and physical therapy, and valid for patients undergoing anterior cruciate ligament reconstruction, and can be used to evaluate the course of knee injury and treatment outcome.

Knee injury and Osteoarthritis Outcome Score (KOOS) - validation and comparison to the WOMAC in total knee replacement.

TL;DR: The Knee injury and Osteoarthritis Outcome Score (KOOS) is a valid, reliable, and responsive outcome measure in total joint replacement and may be at least as responsive as the WOMAC.
