Knee Pain After Intramedullary Nailing in the Tibia

Study Overview
=================
Brief Summary
-----------------
The primary objective of this study is to evaluate the long-term outcome after inserting an intramedullary nail in patients with a tibial shaft fracture using an injury-specific questionnaire.

Detailed Description
-----------------
Introduction The treatment of choice for unstable diaphyseal fractures in the tibia is reamed insertion of an intramedullary nail (IMN) with the additional placement of interlocking screws. The most common complication after insertion of an IMN as treatment of tibial shaft fractures is chronic knee pain with reported rates between 10 % and 87 % with a mean of 47,4 % in metaanalyses. Methods The primary objective of this study is to evaluate the long-term outcome after inserting an IMN in patients with a tibial shaft fracture using an injury-specific questionnaire. This study includes patients operated on five Danish hospitals. A database search was made using operational codes for insertion of an IMN in a five-year period. Patients aged 18 years or older, alive and residing in Denmark at the time of follow-up could be included in the study. These patients then received a Knee Injury and Osteoarthritis Score (KOOS) questionnaire by mail with questions regarding knee-specific symptoms, stiffness, pain, function and quality of life. Questionnaires were filled out and returned to the corresponding physician for further analyze. Patients who were unable to fill out the questionnaire due to concomitant physical condition or who had undergone amputation or further surgery on the affected limb were excluded.

| --- | --- | --- |
| Knee Pain after Tibial Shaft Fracture Treated with Intramedullary Nailing | The primary objective of this study is to evaluate the long-term outcome after inserting an IMN in patients with a tibial shaft fracture using an injury-specific questionnaire. We used the Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire to collect patient data. It is used to assess patient's subjective opinion about symptoms related to the knee and other associated problems. The questionnaire has been translated and validated in Danish and consists of 5 subscales: pain, symptoms, function in daily living (ADL) function in sports and recreation and knee-related QOL. Each subscale has between 4 and 17 questions (a total of 42 questions) with each question having 5 options ranging from no symptoms to severe symptoms. Each question gets a score from 0-4 and a score from 0-100 is calculated. 100 indicating no symptoms and 0 indicates major symptoms. | 1st of November 2009 till 30th of October 2014. |
