Objective To explore the treatment of the malunited fracture of the tibial plateau. Methods From June 2000 to June 2005, reconstruction was performed on 29 patients (18 males, 11 females; age, 1943 years, average, 31.6 years) with the malunited fracture of the tibial plateau. The injury duration ranged from 2.5 months to 2 years, averaged 9.7 months. After the injury, the plasterexternal fixation was performed on 8 patients and operation was performed on the other 21 patients. The operation was involved in the use of screws in 11 patients, anatomic plates, Golf plates and allotype plates in 8 patients, external fixation braces in 2 patients. A complicating injury to the anterior cruciate ligament (ACL) was found in 4 patients, an injury to the posterior cruciate ligament(PCL) in 2 patients, an injury to both ACL and PCL in 1 patient, and an injury to the meniscus in 6 patients. Reestablishment was performed on 19 patients, high tibial osteotomy on 7 patients, and osteotomy of the half tibial metaphysis on3 patients. Results Base on the followup for 8 months to 3 years(average, 13.6 months), the comprehensively scoring assessment showed that an excellent result was achieved in 8 patients, good in 15, fair in 4, and poor in 1, with an excellent and good rate of 82.1%, according to the Hohl knee joint function assessment on the pain, active movement, motion range, stability, and selfassessment. ConclusionFor the reconstruction of the malunited fracture of the tibial plateau, the satisfactory therapeutic effectiveness can only be achieved if the proper indications are identified and the suitable operative methods are adopted. The total knee replacement is only applicable to the elderly patient, and for the young patient, the reconstruction should be performed.
ObjectiveTo evaluate the short-term effectiveness of a modified Laprade technique in the treatment of lateral multi-ligament injuries of knee by anatomical reconstruction of posterolateral complex (PLC) and anterior lateral ligament (ALL).MethodsBetween June 2013 and July 2015, 13 cases of lateral multi-ligament injuries of knee were treated. There were 9 males and 4 females with an average age of 38 years (range, 23-49 years). The injury was caused by traffic accident in 7 cases, falling from height in 4 cases, and sport injury in 2 cases. The time between injury and operation was 18-92 days (mean, 43 days). The results of anterior and posterior drawer tests and Lachmann test were positive, and all cases complicated by varus and external rotation instability. The Lysholm score of the knee was 38.4±7.7. According to International Knee Documentation Committee (IKDC) scoring, all were rated as grade D. According to Fanelli classification criteria, all were classified as type C. Anterior cruciate ligament, posterior cruciate ligament, PLC, and ALL were reconstructed simultaneously with autogenous tendon.ResultsAll incisions healed at stage I and no complication occurred. All patients were followed up 12-36 months (mean, 19 months). At last follow-up, the results of anterior and posterior drawer tests and Lachmann test were negative; 2 cases had varus instability, and 1 cases had external rotation instability. There was no anterior external rotation instability. The Lysholm score of the knee was 88.6 ±12.7, showing significant difference when compared with preoperative score (t=13.852, P=0.000). According to IKDC scoring, 8 cases were rated as grade A, 4 as grade B, and 1 as grade C; significant difference was found when compared with preoperative value (Z=3.182, P=0.000).ConclusionIn the treatment of lateral multi-ligament injuries knee, anatomical reconstruction of PLC and ALL with a modified Laprade technique can obtain good short-term effectiveness.
