Background: Rupture of anterior crutiate ligament (ACL) is the most common severe injury of the knee. Following complete ACL rupture, insufficient revascularization prevents the complete healing of ACL as a result of which reconstruction methods are necessary. The appropriate treatment of this lesion remains a controversial issue. The most popular techniques of treatment are hamstring graft and bone-patellar tendon-bone graft. Therefore, the current study aimed to determine and compare the clinical results of ACL reconstruction on. Methods: This was a randomized prospective clinical trial involving 50 patients (20 to 35 years old), who had suffered from ACL tearing and had undergone surgery from December 2008 to December 2009. Known cases of psychological disease, functional disturbance diseases, and patients who had another medical condition or did not cooperate well in the follow-up period were excluded from the study. Patients were randomized into two equal groups. The first group was treated using bone-patellar-bone graft method and second group by hamstring graft method. Follow up examinations were performed at 2, 4, 6 and 9 months after operation. Data including the patient information, knee range of motion, rehabilitation time, anterior knee pain score, and antro-posterior and mediolateral plane translation were registered. Collected Data were analyzed by student’s t-test and Mann-Whitney test. Findings: 50 patients (49 men and 1 woman) with total mean age of 26.6 ± 4.5 (P value = 0.9) participated in the current study. There was a significant difference between the mean visual analogue scales of the two groups. , mean knee range of motion, antro-posterior and mediolateral plane translation scores, and rehabilitation time were not statistically significant during different times. Conclusion: In conclusion, since pain is a known post-oprative symptom, and due to the significantly low average pain in the hamstring group, it may be best to choose this method as the treatment method of anterior cruciate ligament reconstruction.

Reconstruction of the torn ACL is emphatically offered in active individuals as by this operation, we prevent osteoarthritis, knee instability and injury to the meniscus. There are numerous methods for graft fixation in the femoral tunnel in ACL reconstruction. If the graft proves to be stable after the operation, patients would not complain of giving way knee joints. In this clinical trial, we compared transfemoral pinning with endobutton fixation of hamstring graft in arthroscopic ACL reconstruction by examining knee stability and use of other relevant functional tests. "n"nMethods : Fourteen Patients who had undergone arthroscopic ACL reconstruction in Shariati Hospital during the years 2008-2009 and were being followed up were evaluated at least 15 months post-operatively by physical examination and the use of an arthrometer made by the Faculty of Mechanics of Sharif Technical University."n"nResults : The results showed that two out of seven patients in which their ACL had been reconstructed by hamstring graft fixation by endobutton technique, and in one out of seven patients who had undergone ACL reconstruction by hamstring graft fixation through transfemoral pinning, Lachmann test (in 25 position) was greater than 5 mm but there were not any complaints of giving way knee joints."n"nConclusion: The clinical results of ACL reconstruction by transfemoral pinning technique seems to be superior to the reconstruction by endobutton technique. "n"nKeywords: Anterior cruciate ligament, ACL reconstruction, endobutton, hamstring graft, transfemoral pinning.

Background and Aim: Anterior cruciate ligament (ACL) injury is common in sports competition and training. Following ACL rupture, neuromuscular system performance is disrupted. Perturbation training can improve the function of patients with ACL reconstruction. The aim of the present study was to assess the effects of perturbation training on ground reaction force and functional status of these patients. Materials and Methods: Twenty patients with ACL reconstruction were randomly assigned into intervention (mean age: 24/2 ±3/4 years) and control (mean age: 27/1± 2/5 years) groups. The intervention group performed ten sessions perturbation training with rocker board, wobble board and Bosu. Peak vertical ground reaction force (GRF) and time to peak vertical GRF were recorded by KISTLER force plate during single leg landing from a 30cm height step. In addition, cross hop test also was evaluated as a functional test. Results: Before perturbation training, both GRF and time to peak vertical GRF in reconstructed knee had not significant difference between two groups (P>0/05). In addition, functional test score had not significant difference between the groups (P=0/62). Following perturbation training, peak vertical GRF in reconstructed knee was greater than that in control groups (P<0/003).Although time to peak vertical GRF in reconstructed knee increased, there was not statistically significant difference between two groups (P=0/50). Furthermore, functional test score was statistically greater in intervention group (P=0/03). Conclusion: This s tudy showed that perturbation training can improve functional status in patients with ACL reconstruction. In addition, force plate findings indicated that the patients tolerated more forces at longer time in single leg landing. [ABSTRACT FROM AUTHOR]

Background: Rupture of anterior crutiate ligament (ACL) is the common severe injury of the knee. Following complete (ACL) rupture, insufficient re-vascularization by preventing complete healing of ACL leads to need of reconstruction methods. Optimal treatment is controversy. The most popular techniques are hamstring graft and bone-patellar tendon-bone graft. So we decided to design the study. Methods: Comparative study of treatment result of ACL reconstruction with two procedures (bonepatellar- bone and hamstring in patients. Materials and method: randomized prospective clinical trial involving 50 patients (20 to 35 years old) with an ACL tearing through 2008 December to 2009 December undergo operation. Known cases of psychological disease, functional disturbance diseases and patients who had another medical condition or had not good cooperation in follow up excluded. Patients randomized into two equal groups. First group bone-patellar-bone graft and second one hamstring graft. Follow up examination were performed at 2, 4, 6 and 9 mounts later after operation. Data include knee range of motion, rehabilitation time, anterior knee pain score, antro-posterior and mediolateral plane translation was registered. Collected Data's were analyzed by t-paired test and Mann-Whitney test. Findings: 50 patients (49 men and 1 women) with total mean age 26.6 ± 4.5 (p value=0.9). Mean anterior knee pain had statistically significant, mean knee range of motion; antro-posterior and mediolateral plane translation score were not statistically significant. Conclusion: by conclusion of postoperative anterior knee pain as a marker of morbidity, can better be prevented by using hamstring tendon graft technique. [ABSTRACT FROM AUTHOR]
