Article: Preoperative factors correlating with prolonged range of motion deficit after anterior cruciate ligament reconstruction.
[show abstract] [hide abstract]
ABSTRACT: Impaired postoperative range of motion remains one of the most frequent complications after anterior cruciate ligament reconstruction. This study was undertaken to determine the preoperative factors associated with prolonged range of motion deficit after anterior cruciate ligament reconstruction. Cohort study; Level of evidence, 3. Between January 2007 and March 2008, a consecutive series of 217 patients underwent anterior cruciate ligament reconstruction and were reviewed at 6 weeks and 3 months after surgery. In this series, all data of patients who required a further surgery for arthrolysis until December 2009 were studied. Goniometric range of motion measurement was performed the day before surgery and at 6 weeks and 3 months postoperatively. Bone contusions were analyzed on preoperative magnetic resonance imaging (MRI). All MRI scans were performed in the 6 months before surgery. Seven potential risk factors-age, sex, limited preoperative range of motion, meniscal lesions, bone contusion(s), operative delay less than 45 days, and rehabilitation-were assessed using univariate analysis. The correlations between the significant factors previously identified were analyzed further using multivariate logistic regression analysis. Limited preoperative range of motion (P < .001), typical bone contusions of the lateral compartment (P < .001), operative delay less than 45 days (P = .003), and female sex (P = .049) were found to be significantly correlated with delayed recovery. The limited preoperative mobility and the presence of typical contusions were strongly correlated (P < .001). In the group of patients who underwent surgery within 45 days, delayed recovery was strongly correlated with limited preoperative mobility (P = .0008) and to the presence of typical contusions (P < .001). Arthrolysis was correlated with delayed range of motion (odds ratio [OR], 8.2; 95% confidence interval [CI], 1.9-50; P =.001) and bone bruise (OR, 7.6; 95% CI, 1.7-46.1; P = .002). Preoperative limited range of motion and typical bone bruises of the lateral femoral condyle and tibial plateau are major risk factors for a difficult rehabilitation after anterior cruciate ligament reconstruction.The American journal of sports medicine 10/2010; 38(10):2034-9. · 3.61 Impact Factor -
Article: Clinical and operative characteristics of cyclops syndrome after double-bundle anterior cruciate ligament reconstruction.
[show abstract] [hide abstract]
ABSTRACT: The purpose of this study was to investigate the clinical and operative characteristics of cyclops lesion in a consecutive series of patients with anterior cruciate ligament (ACL) double-bundle reconstruction. Included were 387 patients who underwent an ACL double-bundle reconstruction with quadriceps or hamstring tendons and were followed up at 6 weeks and 3, 6, and 12 months for clinical examination. When a persistent extension deficit was observed 3 months postoperatively, magnetic resonance imaging was performed to eventually diagnose a cyclops syndrome, and arthroscopic removal of the nodule was performed in these cases. The aspect of the nodule was explored before debridement. These patients were reviewed at a mean follow-up of 12 months (minimum, 6 months; maximum, 20 months) after nodule debridement for evaluation. There were 14 patients who had cyclops syndrome (3.61%); 10 cases (5.37%) occurred in the quadriceps tendon group and 4 cases (1.99%) in the hamstring tendon group. In the postoperative period these patients had a mean loss of extension of 6° (range, 5° to 15°), and 78.6% had pain and/or swelling. At the 6-week follow-up, 78.6% of the 14 patients had a significant quadriceps dysfunction associated with an active extension deficit. During arthroscopic debridement, the cyclops lesion was always located on the roof of the intercondylar notch. At the last follow-up, 12 patients had full range of motion, but an extension loss was still present in 2 patients. On the International Knee Documentation Committee objective evaluation, 78.5% of patients were graded A, 14.3% were graded B, and 7.2% were graded C. Cyclops syndrome after double-bundle ACL reconstruction was more frequently observed with quadriceps tendon graft than with hamstring graft. Its unique characteristic is that the nodule localization is from the roof of the intercondylar notch. The majority of the patients with cyclops syndrome presented with a significant quadriceps dysfunction and an active extension deficit in the immediate postoperative period.
