Effect of Transverse Versus Longitudinal Incisions on Anterior Knee Pain After Tibial Nailing (TRAVEL): A Multicenter Randomized Trial with 1-Year Follow-up.

BACKGROUND: Anterior knee pain is common after tibial nailing, and its origin is poorly understood. Literature suggests it may be related to infrapatellar nerve injury. The aim of this study was to compare the effect of a transverse (potentially infrapatellar nerve-sparing) incision versus a longitudinal incision for the insertion of a tibial nail with respect to anterior knee pain. METHODS: Patients with a tibial shaft fracture undergoing treatment with use of an intramedullary nail were randomized to a transverse incision (n = 68) or longitudinal incision (n = 68) in multiple centers. The primary outcome measure was kneeling pain based on a numeric rating scale (NRS). Secondary outcome measures included knee pain during daily activities, functional outcome (Short Musculoskeletal Function Assessment and Lower Extremity Functional Scale), quality of life (EuroQol-5 Dimensions), activity resumption, complications, reoperations, and costs within 1 year after trauma. RESULTS: At 12 months, the estimated marginal mean for kneeling pain was 2.4 (95% confidence interval [CI], 1.6 to 3.2) in the transverse incision group and 3.7 (95% CI, 3.0 to 4.5) in the longitudinal incision group. Regression analysis showed no significant difference between the groups over time. Knee pain scores for daily activities, functional outcome scores, and quality of life were also comparable between the groups. Signs of infrapatellar nerve injury were found less often after a transverse incision (18% versus 54%; p < 0.001). The median total (direct and indirect) costs per patient were €10,468 in the transverse incision group and €11,066 in the longitudinal incision group. Loss of productivity accounted for 67% and 52% of the total costs in the 2 groups, respectively. CONCLUSIONS: A transverse incision reduces injury to the infrapatellar nerve, but anterior knee pain scores and function are comparable after use of a transverse or longitudinal incision for tibial nail insertion.

Measurement properties of Patient-Reported Outcome Measures in patients with a tibial shaft fracture; validation study alongside the multicenter TRAVEL study.

The aim of this study was to evaluate the measurement properties of the Short Musculoskeletal Function Assessment (SMFA) and Lower Extremity Functional Scale (LEFS) in patients who sustained a tibial shaft fracture, by comparing them with the scores of a general health-related quality of life instrument scale (i.e., EuroQoL-5D). Data of 136 patients participating in a multicenter randomized controlled trial comparing incisions for intramedullary nail entry in adults with a tibial shaft fracture were used. Patients completed the SMFA, LEFS, EQ-5D and an anchor question at 2 and 6 weeks, and at 3, 6 and 12 months. Reliability (internal consistency), construct validity, responsiveness (longitudinal validity), floor and ceiling effects, minimal important change (MIC), and smallest detectable change (SDC) were determined. The SMFA and LEFS (sub)scales showed adequate internal consistency (0.84<α<0.94). Construct and longitudinal validity were also adequate (correctly predicted hypotheses between 83%-100%). Floor effects were not present. Ceiling effects were present at 12 months for the SMFA lower extremity dysfunction and bother subscales (22% and 19%, respectively) and the LEFS (19%). MICs could not be determined with the available data. The SDC was 13.84 points for the SMFA and 38.74 points for the LEFS. This study confirms that the SMFA and LEFS are reliable, valid, and responsive instruments for monitoring functional limitation in patients after sustaining a tibia shaft fracture during at least the first six months post-injury. An anchor-based MIC for the SMFA remains to be determined.

Anterior knee pain and functional outcome following different surgical techniques for tibial nailing: a systematic review.

PURPOSE: The aim of this systematic review was to compare knee pain and function after tibial nail insertion through an infrapatellar, semi-extended and suprapatellar technique. METHODS: A search was carried out to identify articles with an exact description of the method used for insertion of the tibial nail and description of the outcome parameters (knee pain or function). Data on study design, population, rate and severity of anterior knee pain and function scores were extracted. Pooled rates and scores were calculated. RESULTS: 67 studies with 3,499 patients were included. The pooled rate of patients with anterior knee pain was 38% (95% CI 32-44) after nail insertion through an infrapatellar approach and 10% (95% CI 1-26) after insertion through a suprapatellar approach. Pooled analysis was not possible for the semi-extended technique. Knee pain scores as measured by visual analogue score (0-10) ranged from 0.2 (95% CI - 0.1-0.5) for general knee pain to 3.7 (95% CI 1.3-6.1) for pain during kneeling. Pooled estimates for the Lysholm score were 87 points (range 77-97) for the infrapatellar technique and 85 points (range 82-85) for the suprapatellar technique. Iowa Knee scores were 94 (range 86-96) and Anterior Knee Pain Scale scores were 76 (range 75-80) after infrapatellar nail insertion. DISCUSSION: Depending on the technique used, the proportion of patients with knee pain after tibial nailing varied between 10 and 38%. The actual measured knee pain scores were, however, surprisingly low. Knee function was good for both the infra- and suprapatellar technique.

Health care and productivity costs for isolated tibia shaft fracture admissions in The Netherlands.

The aim of this study was to provide a detailed overview of age and gender specific health care costs and costs due to lost productivity for hospital admitted patients with an isolated tibia shaft fracture in The Netherlands between 2008 and 2012. Injury cases and length of hospital stay were extracted from the National Medical Registration. Information on extramural health care and work absence were retrieved from a patient follow-up survey on health care use. Medical costs included ambulance care, in- hospital care, general practitioner care, home care, physical therapy, and rehabilitation/nursing care. An incidence-based cost model was applied to calculate direct health care costs and lost productivity in 2012. Total direct health care costs for all patients admitted with a tibia shaft fracture (n = 1,635) were €13.6 million. Costs for productivity loss were € 23.0 million. Total costs (direct health care and lost productivity) per patient were highest for men aged 40-49 years mainly due to lost productivity, and for women aged > 80 years, due to high direct medical costs.

Epidemiologic trends for isolated tibia shaft fracture admissions in The Netherlands between 1991 and 2012.

INTRODUCTION: Population-based knowledge on the occurrence of specific injuries is essential for the allocation of health care services, optimization of preventive measures, and research purposes. Therefore, the aim of this study was to examine long-term nation-based trends in the incidence rate, trauma mechanism, hospital length of stay (HLOS), treatment, and outcome of hospital-admitted patients with an isolated tibia shaft fracture between 1991 and 2012 in The Netherlands. METHODS: All hospital-admitted patients in The Netherlands between 1991 and 2012 with an isolated tibia shaft fracture were included. Age and gender-standardized incidence rates were calculated for each year. Data were extracted from the National Medical Registration. RESULTS: The incidence rate for men decreased to 13.8/100,000 person years (py). For women the incidence rate remained stable with 7.2/100,000 py. Incidence showed a peak for adolescent men (15-19 years), and increased in both genders from 65 years onwards. Since 1993 the mean HLOS for isolated tibia fractures reduced from 10.8 to 5.4 days. Mean HLOS increased with age. Mean years lived with disability (YLD) was 4.5 years, declined linearly with age, and showed no gender effect. CONCLUSIONS: In 22 years, the incidence rate of hospital admitted patients with an isolated tibia shaft fracture in The Netherlands dropped with 12%, which was mainly attributable to a 15% decline among men. Incidence rate, trauma mechanism, and HLOS were age and gender related. HLOS also reduced over time. Operation rate and YLD were only age related.

An infrapatellar nerve block reduces knee pain in patients with chronic anterior knee pain after tibial nailing: a randomized, placebo-controlled trial in 34 patients.

Background and purpose - Anterior knee pain is common after tibial nailing. Its origin is poorly understood. Injury of the infrapatellar nerve is a possible cause. In this randomized controlled trial we compared changes in knee pain after an infrapatellar nerve block with lidocaine or placebo in patients with persistent knee pain after tibial nailing. Patients and methods - Patients with chronic knee pain after tibial nailing were randomized to an infrapatellar nerve block with 5 ml 2% lidocaine or placebo (sodium chloride 0.9%), after which they performed 8 daily activities. Before and after these activities, pain was recorded using a numeric rating scale (NRS; 0-10). Primary endpoint was the change in pain during kneeling after the infrapatellar nerve block. Secondary outcomes were changes in pain after the nerve block during the other activities. Results - 34 patients (age 18-62 years) were equally randomized. A significant reduction of the NRS for kneeling pain with an infrapatellar nerve block with lidocaine was found compared with placebo (-4.5 [range -10 to -1] versus -1 [-9 to 2]; p = 0.002). There were no differences between the treatments for the NRS values for pain during other activities. Interpretation - Compared with placebo, an infrapatellar nerve block with lidocaine was more effective in reducing pain during kneeling in patients with chronic knee pain after tibial nailing. Our findings support the contention that kneeling pain after tibial nailing is a peripheral nerve-related problem.
