Patient injury claims for posterior cruciate ligament injury: a nationwide registry study in Finland.

BACKGROUND AND PURPOSE: Posterior cruciate ligament (PCL) injuries usually occur in combination with other ligamentous knee injuries. The outcome varies and may be poor due to suboptimal treatment. We investigated claims following PCL injury treatment on a nationwide scale. PATIENTS AND METHODS: All patient PCL injury claims filed in Finland from 1997 to 2015 were collected from the Patient Insurance Centre (PIC) register. We reviewed and analyzed all records to determine the causes of claims. General background data were obtained from the National Care Register for Social Welfare and Health Care (HILMO). RESULTS: We found out from HILMO background data that, during the 19-year study period, 1,891 PCL and 1,380 multiligament reconstructions were performed in 99 different hospitals. The number of PCL injuries treated conservatively is unknown. During this same period, 49 claims arrived at the PIC, and 39/49 of these patients were operated on. 12/49 claims were compensated. Of these 12 claims, 6 were compensated for technical errors and 4 were compensated for diagnostic delays. CONCLUSION: The number of patient injury claims was few, and compensated claims were even fewer. Technical errors and diagnostic delays were the most common reasons for reimbursement.

Comparison of clinical results of anteromedial and transtibial femoral tunnel drilling in ACL reconstruction.

BACKGROUND: A femoral bone tunnel in ACL reconstruction can be constructed from the outside in or from the inside out. When doing it inside out, the approach can be via the anteromedial (AM) portal or through the tibial bone tunnel. It has been suggested that better results might be expected by doing it anteromedially. Clinical results after femoral tunnel drilling via the AM or transtibial (TT) techniques in reconstruction of anterior cruciate ligament (ACL) are presented. METHODS: Three hundred patients with ACL injuries were chosen for this study from previously collected data on ACL reconstructions. They were divided into two groups: 150 patients treated with AM drilling and 150 treated with TT drilling. In the AM group, the reconstructions were performed using a semitendinosus graft with the Tape Locking Screw (TLS™) technique (n = 87) or Retrobutton™ femoral and BioScrew™ tibial fixation with a semitendinosus-gracilis graft (n = 63). In the TT group, the fixation method used was Rigidfix™ femoral and Intrafix tibial fixation with a semitendinosus-gracilis graft. The evaluation methods were clinical examination, knee scores (Lysholm, Tegner and IKDC) and instrumented laxity measurements (KT-2000™). Our aim was to evaluate if there was better rotational stability and therefore better clinical results when using AM drilling compared to TT drilling. RESULTS: After excluding revision ACL reconstructions, there were 132 patients in the AM group and 133 in the TT group for evaluation. At the 2-year follow-up, there were 60 patients in the AM group (45.5%) and 58 in the TT group (43.6%). There were no statistically significant differences between the groups in any of the evaluation methods used. CONCLUSION: Both drilling techniques resulted in improved patient performance and satisfaction. We found no data supporting the hypothesis that the AM drilling technique provides better rotational stability to the knee. TRIAL REGISTRATION: ISRCTN registry with study ID ISRCTN16407730.

Anterior cruciate ligament reconstruction-related patient injuries: a nationwide registry study in Finland.

Background and purpose - Treatment outcomes of anterior cruciate ligament (ACL) injuries are generally good, but complications after ACL reconstruction (ACLR) can result in long-lasting problems. Patient injury claims usually fall on the more severe end of the complication spectrum. They are important to investigate because they may reveal the root causes of adverse events, which are often similar regardless of the complication's severity. Therefore, we analyzed ACL-related patient injuries in Finland, the reasons for these claims, causes of complications, and grounds for compensation.Patients and methods - We analyzed all claims filed at the Patient Insurance Centre (PIC) between 2005 and 2013 in which the suspected patient injury occurred between 2005 and 2010. This study also reviewed all original patient records and available imaging studies. General background data were obtained from the National Care Register for Social Welfare and Health Care (HILMO).Results - There were 248 patient injury claims, and 100 of these were compensated. Compensated claims were divided into 4 main categories: skill-based errors (n = 46), infections (n = 34), knowledge-based errors (n = 6), and others (n = 14). Of the compensated skill-based errors, 34 involved graft malposition, 26 of them involved the femoral-side tunnel. All compensated infections were deep surgical site infections (DSSI).Interpretation - This is the first nationwide study of patient injuries concerning ACLRs in Finland. The most common reasons for compensation were DSSI and malposition of the drill tunnel. Therefore, it would be possible to decrease the number of serious complications by concentrating on infection prevention and optimal surgical technique.
