Pretibial cyst formation is a rare occurrence after anterior cruciate ligament (ACL) reconstruction. We report this complication after ACL revision surgery using tibialis anterior allograft. This complication seems to be the consequence of a direct communication between the joint and the cyst through the tibial tunnel. In the present study, the authors report that there is a pretibial cyst formation after a revisional ACL reconstruction.

Purpose: To compare the mid-term follow-up results of anterior cruciate ligament(ACL) reconstruction with the bone-patellar tendon- bone(BTB) autograft to those with the BTB allograft. Materials and Methods: Retrospective study was performed in 59 cases with BTB autograft and 42 cases with BTB allograft. Evaluations include Lysholm score, 2000 IKDC subjective knee score, Shelbourne patello-femoral pain score , Lachman test, pivot shift test, KT-1000 arthrometer test and 2000 IKDC knee examination. Results: There were no significant statistic differences between two groups in Lysholm score and 2000 IKDC subjective knee score of more than 70 (p<0.05). Five cases(8.5%) showed the patello-femoral pain score less than 80 according to Shelboume with autograft group and two cases(4.8%) with allograft group (p<0.05). Lachman test, pivot shift test and KT-1000 arthrometer test showed no significant statistic differences between two groups(P<0.05). Fifty-four cases(91.5%) were normal or nearly normal according to the 2000 IKDC knee examination with autograft group and thirty-eight cases(90.4%) with allograft group(p<0.05).Conclusion: BTB allograft as well as BTB autograft is considered to be an acceptable choice for ACL reconstruction.

Purpose: The purpose of this study was to compare the clinical results of the arthroscopic anterior cruciate ligament reconstruction used by Bone-Patella tendon-Bone autograft and Achilles tendon allograft. Materials and Methods: We reviewed the results of patients who had been managed with arthroscopic anterior cruciate ligament reconstruction using different graft such as Bone-Patella tendon-Bone autograft and Achilles les tendon allograft. 60patients (average age, 33.5 years)were retrospectively evaluated. The one group(average age, 33.4 years) was 32 patient who had been managed with arthroscopic anterior cruciate ligament reconstruction using Bone-Patella tendon-Bone autograft. The other group(average age, 32.1 years) was 28 patient who had been managed with arthroscopic anterior cruciate ligament reconstruction using Achilles tendon allograft. 2 groups were evaluated subjectively by Lysholm knee scoring scale and objectively by KT-2000 arthrometer. The follow-up period was more than a year(average, 18 month). An early rehabilitation protocol was instituted. Results: On Lysholm knee scoring scale, the final evaluation was nearly normal in all patients. We could not find statistical difference among the two groups by KT-2000TM arthrometer. Conclusion: The use of allografts may be an acceptable choice for ACL reconstruction.

Purpose: We describe clinical, radiographic, MRI and pathologic findings as well as final outcome after simple curettage and bone graft of cystic fibrous dysplasia (FD) in the long bone, which has been rarely documented in the literature. Materials and Methods: Clinical records, radiographs, MRI and histologic slides of 11 patients with cystic FD in the long bone were retrospectively analyzed. Results: Six patients complained pain for several months, 4 patients presented pain after trivial injury event, and 1 patient suffered pathologic fracture. The mode of involvement was monostotic in 10 patients and polyostotic in l patient. The femur was affected in 7 patients, the humerus in 3, and the radius in 1. Radiography showed prominent, expansive lysis associated with ground-glass density of FD. MRI revealed 2 different signals of FD and cyst. Microscopic examination revealed classic findings of FD and non-specific cystic degeneration. The final outcome was satisfactory in every patient. Local recurrence was not observed. Conclusion: Cystic FD in the long bone seems not as rare as the scarcity of reported cases would indicate. MRI features provide a basis for differential diagnosis between benign cystic change and malignant transformation. Cystic FD would be an indication for surgery and simple curettage with allo-chip-bone graft is effective.

Dental implants are universal restorative method on edentulous site in oral cavity and generally recognized by patients as well as clinicians. Rapid bone resorption of labial portion of maxillary anterior area is performed due to dental trauma, chronic periodontitis, and so on. Accordingly, Implants on maxillary anterior alveolar ridge with narrow labiopalatal width would lead to bony defects of dehiscence or fenestration. In this case, guided bone regeneration procedure is used to augment maxillary anterior alveolar ridge. It can have mechanical and biological advantages to mix tissue adhesive with bone graft materials in guided bone regeneration procedure. In these cases, when the dehiscence or fenestration defects was occurred by dental implants on maxillary anterior alveolar ridge with narrow labiopalatal width, guided bone regeneration procedures were performed with various combination of particle bone graft materials(allograft, xenograft, and alloplast) mixed with fibrin glue, excepting autogerous bone. We reported that all of 4 cases showed favorable alveolar ridge augmentations.

Clinical assessment of bone-graft healing in the maxillofacial region is generally limited to clinical evaluation, radiographs, and biopsy. Sequential interpretation of osseous repair, more sensitive than with conventional radiography is possible with a non-invasive, non-destructive radionuclide method. Technetium-99m radionuclide bone scan was used in the evaluation of the progress of osteogenic activity in autologous iliac bone graft and freeze-dried bone allograft of dog's mandible. Bone scan was performed at 1wk, 2wk, 4wk, 6wk, and 8wk after grafting. In autologous graft the activity ratio for the graft bone remained greater than that of the host since 2자 after grafting; however, in lyophilized allograft the activity ratio for graft bone was greater than that of the host at 6자 after grafting.
