  • Most of bucket handle meniscal tears are associated with anterior cruciate ligament (ACL) deficiency. Lateral meniscus lesions are more common with acute ACL deficiency, where medial meniscus lesions are more associated with chronic ACL deficiency. We reported an ACL deficient knee with bucket handle tears of medial and lateral meniscus of the same knee. The report suggests the need for increased awareness of the possible presence of this. Additionally, we discuss injury mechanism, clinical symptoms, specific signs on Magnetic Resonance Imaging (MRI), and treatment options.

  • Purpose : To analyze changes of the anterior translation, MRI findings and associated injuries at scarring of the torn ACL in the chronic ACL rupture. Materials & Method : From Dec. 1996 to May 2000, 19 patients who were diagnosed as the chronic ACL rupture were studied. We analyzed KT-2000 side to side difference of maximal manual anterior displacement(MMAD), MRI findings and associated injuries. Results : There was statistically significant difference in the average MMAD between the 7 cases$(37\%)$ with scar formation$(2.78{\pm}2.41mm)$ and the 12 cases without scarring$(5.75{\pm}2.52mm)$. The chronic ACL rupture without scarring had more meniscal injuries$(67\%)$ than with scarring$(28\%)$. MRI showed that relatively straight bands toward expected insertion site with single large fragment(5 cases) and continuous band with focal angulation(2 cases). Conclusion : If relatively straight bands toward expected insertion site with single large fragment or continuous band with focal angulation on MR imaging is showed in the patient without significant anterior translation at arthrometer, the possibility of the scar formation of the torn ACL should be considered. We think that the chronic ACL rupture with scarring had less meniscal injuries than without scarring will give additional information on the natural history of ACL injuries.

  • Simultaneous acute rupture of the anterior cruciate ligament (ACL) and the patellar tendon is a very unusual injury. That is difficult to diagnose in initial evaluation of knee injury, because the patellar tendon rupture is often missed. We report a 26 year-old male patient who was treated with ACL reconstruction using achilles allograft and direct patellar tendon repair with achilles allograft augmentation. The patient had the stable knee and full range of motion. It's clinical results were excellent(Lysholm score 93, Tegner activity score 6).

  • Purpose: to describe the histologic appearance of the type III bone bruise in knees which had sustained an acute anterior cruciate ligament (ACL) rupture. Materials and Method: Twenty-five patients who sustained acute ACL rupture were prospectively enrolled in this study. On MRI, 14 patients demonstrated type III bone bruise on lateral femoral condyle, and 11 patients didn't demonstrated bone bruise. Arthroscopic evaluation and biopsy of the articular cartilage and subchondral bone wert performed before ACL reconstruction. Histologic and immunohistochemical evaluations were done. Results: There was no difference between the bone bruise and control group in the hematoxylin-eosin staining for cell distribution, Masson's trichrome staining for collagen and immunohistochemical staining for type I and type II collagen (p>0.05). But in the safranin-O staining for glycosaminoglycan distribution, the bone bruise group had an evidence of decreased staining at the superficial and middle layers, compared with the control group (p<0.05). We also found fatty change of bone marrow in calcified zone of the bone bruise group with safranin-O staining. Conclusion: We suggest that the type III bone bruise found on MRI indicates a substantial damage to normal articular cartilage homeostasis, and may induce further damage of the articular cartilage.

  • Purpose : To evaluate tile clinical results of resorbable meniscal arrow fixation for repairable meniscal tear with concurrent anterior cruciate ligament(ACL) reconstruction. Materials and Methods : Between April, 1997 and June, 1999, we performed resorbable meniscal arrow fixation and ACL reconstruction simultaneously for 18 cases of repairable meniscal tears with ACL injuries. Nine cases were acute injuries, 5 cases, subacute and 4 cases, chronic. The average follow-up was 21.5 months($12\~38$ months). Results : The healing rate was $89\%$ for acute injuries, $80\%$ for subacute injuries and $50\%$ for chronic injuries. Conclusion : Resorbable meniscal arrow fixation with concurrent ACL reconstruction is a good treatment modality for acute and subacute injuries.

  • While the cruciate ligament has a profuse vascular response following injury, spontaneous repair does not occur. This may result from the fact that synovial fluid dilution of the hematoma following injury prevents the formation of a fibrin clot and thus the initiation of the healing mechanism. Another theory suggests that the dynamic nature of the fascicles of the anterior cruciate ligament(ACL) through even small ranges of motion prohibits spontaneous union to these fibers. But we experienced two cases of spontaneous healing of partially injured ACL. Initially they showed more than grade II anterior instability. 6 mm difference by stress roentgenographs(pull view) and difference of 8 mm by KT 1000TM arthrometer between the ACL injured knee and normal side knee. Lax, nearly complete tear of ACL and synovial bleeding were noted during arthroscopic examination but the continuity of synovial membrane was seemed to be intact. These cases were treated by conservative management rather than reconstructive procedure. Postoperatively they showed excellent clinical results, no anterior instability and unlimited athletic activity. Based on our clinical experience. we think that cruciate ligament has the spontaneous healing potential in acute stage and middle aged patient. We consider the microfracture technique and initial immobilization for accelleration of healing response of the ACL.

  • Purpose: To compare of the results between anterior cruciate ligament (ACL) reconstruction alone and combined with high tibial osteotomy for ACL ruptured knees with varus alignment. Materials and Methods: We retrospectively reviewed 8 cases of ACL reconstruction combined with high tibial osteotomy (Group I) and 13 cases of ACL reconstruction alone (Group II) for varus angulated ACL ruptured knees (from March 2005 to February 2007). Mean age were 34.1 years (range: 20-53) in Group I, 34.9 years (range: 21-50) in Group II. Average follow up period were 22.6 months (range: 12-35) in Group I, 20 months (range: 13-33) in Group II. We analyzed clinical and radiological results. Results: There were no significant differences in clinical and radiologic results between two groups for IKDC scores, Lysholm knee scores, Lachman test, pivot shift test, KT-2000 arthrometer, $30^{\circ}$ and $90^{\circ}$ anterior drawer stress radiographs. Tegner activity scales and Cincinnati knee ligament rating scales were 4.9, 57.9 in Group I, and 5.6, 72.9 in Group II. Group I was statistically lower than Group II for Tegner activity scales and Cincinnati knee ligament rating scales (p<0.05). Conclusion: There were no significant differences in daily living between ACL reconstruction alone and combined with high tibial ostetomy for varus angulated ACL ruptured knees. However, ACL reconstruction combined with high tibial osteotomy could limit sport activity ability.

  • Arthroscopic anterior cruciate ligament(ACL) reconstruction using four-strand hamstring tendon with looping around transfixing screw in femoral tunnel requires osteointegration between the grafted tendon and bone for stability of the knee. Authors have experienced a histologic finding of osteointegration between the grafted autogenous hamstring tendon and bone in femoral tunnel after arthroscopic ACL reconstruction. A patient received arthroscopic ACL reconstruction with autogenous four strand hamstring tendon for the ACL injury. Traumatic re-rupture of mid-substance of ACL graft was developed at thirteenth week after operation. During the procedures of arthroscopic revision at fifteenth week after initial ACL reconstruction, biopsy was performed at the site of interface between grafted tendon and bone in femoral tunnel. Integration between the grafted tendon and bone was evident by demonstrating the continuity of collagen fiber between bond and tendon. This histologic finding and the low incidence of early graft failure suggest that free tendon autograft attached to bone by looping around a transfixing screw in femoral tunnel undergoes adequate osteointegration between 12 and 15 weeks after surgery and authors thought that insertion of bone chip into the femoral tunnel would accelerate osteointegration procedure.

  • Purpose: The purpose of this study is to evaluate the effect of preservation of the tibial remnant on the synovialization of graft tendon after the reconstruction of anterior cruciate ligament (ACL) based on the second look arthroscopic findings. Materials and Methods: From May 2005 to May 2012, among sixty three patients having ACL reconstruction with the four-strand hamstring using a bioabsorbable cross pin (RigidFix$^{(R)}$) for the femoral tunnel, nineteen patients who had second look arthroscopy were analyzed. We classified them into three groups according to the tibial remnant of the torn ACL for arthroscopic findings. Group 1 had less than 5 mm of a remnant tissue, Group 2 had from 6 mm to 10 mm of it, and Group 3 had more than 11 mm. We estimated the percentage of synovial coverage on the graft tendon during second look arthroscopy. We evaluated Lysholm score and Tegner activity score preoperatively and in the last follow-up. Results: At the time of ACL reconstruction, the mean length of preserved tibial remnant of torn ACL was 2.3 mm in Group 1, 7.4 mm in Group 2, and 13.7 mm in Group 3. In the second look arthroscopy, the average percentage of synovial coverage was 55.4% in Group 1, and 77.9% in Group 2, and 89.7% in Group 3. Lysholm score and Tegner activity score improved from 74.2 and 7.3 preoperatively to 94.1 and 8.5 in the last follow-up. Conclusion: The preservation of tibial remnant of torn ACL influenced the synovial coverage of the graft tendon and the volume of preserved remnant in accordance with the surface of synovial coverage. It would have a good effect on graft healing and preservation of proprioceptive function.
