  • EFFECTIVENESS OF A SUTURE BRIDGE TECHNIQUE FOR REPAIR OF QUADRICEPS TENDON RUPTURE IN UEAEMIC PATIENTS

    ObjectiveTo investigate the effectiveness of a suture bridge technique for quadriceps tendon rupture repair in uraemic patients. MethodsBetween March 2010 and September 2012, 10 uraemic patients (14 sides) with quadriceps tendon rupture were treated with the suture bridge technique. Of them, 8 were male and 2 were female, aged from 30 to 62 years (mean, 54.2 years). The duration of uremia was 3-11 years (mean, 5.5 years);the duration of quadriceps tendon rupture was 5 days to 2 months (median, 12 days). Six cases had a trauma history, and one case had diabetes. The left side was involved in 2 cases, the right side in 4 cases, and both sides in 4 cases. The active range of motion (ROM) of the knees was (115.0±8.3)°in flexion, and (72.5±21.2)°in extension. Lysholm score was 19.5±16.3. X-ray films showed downward shifting of patella. MRI revealed discontinuity between distal quadriceps tendon and upper pole of patella. ResultsThe operation time was 30-50 minutes (mean, 40.3 minutes). Primary healing of incision was obtained in all patients without complications. All patients were followed up 12-25 months (mean, 16.3 months). There was no re-rupture of quadriceps tendon or loosening of internal fixation during follow-up. At last follow-up, the active ROM of the knees was (121.0±7.9)°in flexion, showing no significant difference when compared with preoperative one (t=-2.075, P=0.058); the active ROM was (8.2±6.1)°in extension, showing significant difference when compared with preoperative one (t=11.702, P=0.000). Lysholm score was 84.6±12.4, showing significant difference when compared with preoperative score (t=-16.226, P=0.000). According to the American Knee Society score (KSS), the results were excellent in 4 sides, good in 9 sides, and fair in 1 side, and the total excellent and good rate was 92.9%. At last follow-up, the active ROM of the knee, Lysholm score, and KSS score were significantly better in young patients (<45 years) than in elder patients (≥45 years), and in patients receiving early operation (<2 weeks) than in patients receiving late operation (≥2 weeks) (P<0.05). ConclusionFor fewer traumas and early functional exercise after operation, the suture bridge technique benefits functional restoration of knee joint in uraemic patients. Operation chance and age seem to be important factors to the results. Early operation should be considered when quadriceps tendon ruptured.

  • Improved technique for perforation of patella combined with suture anchor and non-tourniquet for repairing acute rupture of the bone tendon junction of quadriceps tendon

    Objective To investigate effectiveness of a improved technique for perforation of patella combined with suture anchor and non-tourniquet for repairing acute rupture of the bone tendon junction of quadriceps tendon. Methods Between June 2010 and June 2016, 15 patients with acute rupture of the bone tendon junction of quadriceps tendon were treated with the improved technique for perforation of patella combined with suture anchor and non-tourniquet. Of them, 14 were male and 1 was female, aged from 19 to 74 years (mean, 44 years). Seven cases were sports injuries, 5 cases were caused by slipping, and 3 cases were caused by violent trauma. The duration of quadriceps tendon rupture ranged from 3 hours to 3 days (median, 2 days). The right side was involved in 9 cases, and the left side in 6 cases. All of the cases were closed injuries. The patients had no sequelae of limb dysfunction and no limb joint surgery in the past. All the patients received anteroposterior and lateral X-ray films of the knee joint and patella axial films during follow-up. Knee function of the patients after operation was evaluated by Lysholm scoring system and Kujala scoring system. Results The operation time was 50-60 minutes (mean, 55 minutes). The intraoperative blood loss was 50-150 mL, with an average of 87 mL. Primary healing of incision was obtained in all patients without complications. All patients were followed up 12-24 months (mean, 18 months). At 1 year after operation, the knee joint function of all patients recovered well; the knee Lysholm score was 92-96, with an average of 94 and the patellofemoral joint Kujala score was 90-95, with an average of 93. There was no re-rupture of quadriceps tendon or loosening of internal fixation during follow-up. According to the lateral and axial X-ray films at 1 year after operation, the patella depth index, femur trochlea depth, sulcus angle, and Insall-Salvati index were 3.62-4.09 (mean, 3.84), 4.45-6.50 (mean, 5.56), 137-145° (mean, 142°), and 0.90-1.18 (mean, 1.06). The lateral patellofemoral angle increased, and the patellar tilt angle and the patella lateral shift distance reduced, all showing significant differences when compared with preoperative ones (P<0.05). Conclusion The improved technique for perforation of patella combined with suture anchor and non-tourniquet for repairing acute rupture of the bone tendon junction of quadriceps tendon can reconstruct a stable patellofemoral joint, increase the strength of fixing, disperse stress effectively and evenly, and increase the area for tendon-bone healing.
