Purpose: The purpose of this study was to evaluate the posterior cruciate ligament (PCL) reconstruction with single bundle, single-incision technique using Achilles tendon and tibialis anterior allograft with ligament remnant preservation. Materials and Methods: Twenty six patients underwent PCL reconstruction was included. There were 21 males and 5 females. Mean age was 32 years. Used graft was a fresh frozen Achilles tendon allograft (group I, 14 cases) and tibialis anterior allograft (group II, 12 cases). Arthroscopic PCL reconstruction was performed using transtibial, single-incision and single bundle technique with remnant preserving as possible. For clinical evaluation, range of motion, posterior drawer test, Lysholm score, Tegner activity scale, International Knee Documentation Committee (IKDC) grade and posterior stress radiograph were used. The mean follow-up period was 21.6 months (12-40 months). Associated injuries were 5 medial collateral ligament injuries, which were treated by conservative method. Results: Range of motion (ROM) was returned to normal range in 24 cases, but ROM deficit under $10^{\circ}$ flexion was 2 cases at final follow-up period. Preoperative posterior drawer test was 17 cases in grade II and 9 cases in grade III. At final follow-up 13 cases returned within normal grade, 7 cases grade I and 6 cases grade II posterior instability. Lysholm mean score was improved from preoperatively 62 to 90 at final follow-up period. Tegner activity mean scale improved from preoperatively 3.5 to 5.6 at final follow-up period. IDKC grade was grade A was 3 cases, grade B 17 cases, grade C 6 cases. In posterior stress radiograph, posterior displacement was improved from mean 12 mm preoperative to 4.5 mm at final follow-up. There were no statistical differences between two groups in clinical evaluations. There were two cases of re-rupture of graft at the bone-tendon junction in group I. Conclusion: We had successful results of PCL reconstruction with single-incision, single bundle technique using Achilles and tibialis anterior allograft without difference between two groups in patients with PCL injury. There were more re-rupture of graft in Achilles tendon group.

Purpose: We report case of neglected elbow dislocation for three years. Material and method: A 45 years old female patient presented with neglected elbow dislocation for three years. Since the patient had contracture in both lateral and medial collateral ligament of elbow, dissection was done. After total separation of posterior articular capsule and incision of anterior articular capsule, by manual manipulation, reduction of radiohumeral and ulnohumeral joints were obtained. We applied modified Morrey type hinged external fixation in the elbow and done early elbow exercise. Result and Conclusion: Since we have experienced a satisfactory result in the case with neglected elbow dislocation for 3 years by using open reduction and hinged external fixation, we report it with the literature.
Purpose: The least constrained prosthesis is generally recommended in primary total knee arthroplasty (TKA). Nevertheless, a varus/valgus constrained (VVC) prosthesis should be implanted when a semi-constrained prosthesis is not good for adequate stability, especially in the coronal plane. In domestic situations, however, the VVC prosthesis could not always be prepared for every primary TKA case. Therefore, it is sometimes impractical to use a VVC prosthesis for unsual unstable situations. This study provides information for preparing VVC prostheses in the preoperative planning of primary TKA through an analysis of primary VVC TKA cases. Materials and Methods: This study reviewed 1,797 primary TKAs, performed between May 2003 and February 2016. The reasons for requiring VVC prosthesis and the preoperative conditions in 29 TKAs that underwent primary TKA with a VVC prosthesis were analyzed retrospectively. Results: In primary TKA, 29 cases (1.6%) in 27 patients (6 male and 21 female) used VVC prosthesis. Two patients underwent a VVC prosthesis on both knees. The mean age of the patients was 63.4 years old (34-79 years). The mean flexion contracture was 16.2° (-20°-90°), and the mean angle of great flexion was 111.7° (35°-145°). The situations requiring a VVC prosthesis were severe valgus deformity in 10 knees, knee stiffness requiring extensive soft tissue release in 10 knees, previously injured collateral ligaments in five knees, and distal femoral bone defect due to avascular necrosis in four knees. The mean tibiofemoral angle was 25.7° (21°-43°) in 10 cases with a valgus deformity. The mean flexion contracture was 37.5° (20°-90°), and the mean range of motion was 48.5° (10°-70°) in 10 cases with knee stiffness. Conclusion: The preparation of VVC prosthesis is recommended, even for primary TKA in cases of severe valgus deformity (tibiofemoral angle>20°), stiff knee (the range of motion: less than 70° with more than 20° flexion contracture), and the cases with a previous collateral ligament injury. This information will help in the preparation of adequate TKA prostheses for unusual unstable situations.
Displaced tibial spine fractures need the anatomical reduction of the displaced bone fragment to achieve normal range of motion and anterior stability of the knee joint. The purpose of this paper is to describe details of arthroscopic technique using suture hook and pull-out PDS and to evaluate the clinical results. We report 7 cases who underwent arthroscopic reduction and internal fixation using suture hook and pull-out PDS. All cases had fresh fractures generated within 3 weeks. The follow up period was at average 16.6 months. The fracture union was achieved at average 7.4 weeks. Knee exercise was started 2 weeks after the operation. One of the patients, who had combined injury of posterior cruciate ligament and lateral meniscus, showed limitation of knee movement. But he was underwent the arthroscopic fibrolysis at one year later, he returned to normal range of motion. Arthroscopic treatment of displaced tibial spine fracture using suture hook and pull-out PDS showed good results including rigid fixation and early mobilization. Therefore it is thought to be one of the effective operative techniques in treatment of the tibial spine fractures.
Background: The purpose of this study was to evaluate the relationship between variable factors and clinical results following the operative treatment of the tibial plateau fractures. Materials and Methods: The clinical and radiological analysis was performed on 29 cases of the tibial plateau fractures who had been treated with operative treatment and followed up for more than 1 year from January 1991 to December 1997. The analysis of clinical results was performed dividing into age, cause of injury, fracture type of Schatzker classification, associated soft tissue injury and method of operative treatment. Results: According to Schatzker classification, 2 cases(6.9%) were type I, 11 cases(37.9%) were type II, 1 case(3.5%) was type III, 5 cases(17.2%) were type IV, 4 cases(13.8%) were type V, and 6 cases(20.7%) were type VI. In all cases, bony unions were obtained. According to Blokker evaluation, 23 cases(79.3%) of 29 cases were acceptable. Conclusion: We could expect good clinical results if early knee joint mobilization following minimal invasive open reduction and internal fixation could be obtained. Bad clinical results were related with young age group under 30, more than Schatzker classification type IV of high energy trauma and associated injury of anterior cruciated ligment or meniscus.
Purpose: We reported the results of arthroscopically assisted lateral release and medial imbrication for the recurrent patella dislocation. Materials and Methods: Twenty patients (20 knees) underwent arthroscopically assisted surgery for the recurrent patella dislocation. There were 4 males and 16 female. The average age was 20.2 years. All patients had definite trauma history and average follow-up period was 19 months. The surgical results were evaluated according to the Lysholm knee score and the Kujala score. The congruence angle and lateral patellofemoral angle were measured on plain radiograph and the tibial tubercle-trochlear groove distance was calculated on computerized tomography. Results: The median value of preoperative congruence angle was $16.5^{\circ}$ (range, $0.0{\sim}+34^{\circ}$) and the average final follow-up was $-6.4^{\circ}$ (range, $-19{\sim}10^{\circ}$) with statistically significant improvement (p=0.025). The median value of preoperative Lysholm knee score was 70 (range, 63~81) and the final follow-up score had changed to 88 (range, 80~95) with statistically significant improvement (p=0.0341). The median value of preoperative Kujala score was 72 (range, 65~80) and the average final follow-up score showed 87 (range, 80~92) with statistically significant improvement (p=0.024). Recurrent dislocations after surgery occurred in 2 cases, one case which showed positive "thumb to forearm test" had been treated with medial patellofemoral ligament reconstruction. Conclusion: Arthroscopically assisted lateral release and medial imbrication for recurrent patella dislocation without bony malaligmenent showed the effective treatment, but would be inappropriate for the patients with the generalized joint laxity.
Purpose: The purpose of this study is to analyze the relationship between acute anterior cruciate ligament (ACL) injury and bone bruise using the survey for location and incidence of bone bruise. Materials and Methods: From Jan. 2006 to Feb. 2010, 87 knees from who had complaint a traumatic knee pain were diagnosed as acute ACL tear using MRI evaluation. Associated injury, location and incidence of bone bruise were analyzed using MRI. The location of bone bruise on the MRI was classified as medial, central and lateral area on anteroposterior and lateral view of femur and tibia. The bone bruise was classified with Costa Paz classification. Results: Bone bruise of injury during daily living activity were located at medial area on coronary view and anterior area on sagittal view of distal femur, at medial area on coronary view and anterior area on sagittal view of proximal tibia (p=0.024, p=0.021, p=0.025 and p=0.029, respectively). Bone bruise of injury during sports activity were located at lateral area on coronary view and central area on sagittal view of distal femur, at lateral area on coronary view and posterior area on sagittal view of proximal tibia (p=0.014, p=0.015, p=0.018 and p=0.017, respectively). Bone bruise patterns due to traffic accident were inconclusive (p=0.264, p=0.254, p=0.229 and p=0.267, respectively). Conclusion: Injury mechanism of acute ACL injury from activities of daily living or sports activities compared to that of traffic accident showed a more consistent bone bruise patterns. Special attention to acute ACL tear must be paid in case of bone bruise at lateral tibial plateau and lateral femoral condyle.
Purpose: We wanted to evaluate the surgical results of early mobilization after rigid fixation of small coronoid fracture using the tension band technique Materials and Methods: Eight cases of coronoid fracture were fixed with the tension band technique and using K-wire and wire through the medial approach. All the cases were Regan-Morrey type 2. According to O'Driscoll, they were classified as 5 cases of the tip type (subtype 2) and 3 cases of the anteromedial type (1 case of subtype 2, and 2 case of subtype 3). The associated collateral ligament injuries (6 cases) and radial head/neck fractures (4 cases) were managed simultaneously. After immobilization for 5~7 days, active ROM exercise with a fitted hinge brace started and continued till postoperative 6 weeks. The patients were assessed for pain, ROM and functional disability using the Mayo elbow performance score (MEPS) at an average of 11 months (range: 6~28 months). The ulnar nerve symptoms were also investigated. Results: We observed solid union in all the coronoid fractures without hardware failure. An average of 2.2 wires (range: 2~4) were used. The mean extension was $3^{\circ}$(range: $0^{\circ}\sim25^{\circ}$), the mean flexion was $137^{\circ}$(range: $130^{\circ}\sim140^{\circ}$), the mean pronation was $69^{\circ}$(range: $45^{\circ}\sim90^{\circ}$) and the mean supination was $78^{\circ}$(range: $45^{\circ}\sim90^{\circ}$). The mean MEPS was 96 (range: 65~100). Ulnar nerve symptoms occurred at postoperative one day and persisted in one patient with the terrible triad of taking radial head excision and residual medial instability. Conclusion: The tension band technique uses easily obtained, economic K-wires and the wire was strong enough to permit early elbow ROM exercise and the technique might improve the elbow function. It was especially useful for fixation of multiple small fragments.
Purpose : The purpose of this paper is to analyze the clinical results after meniscal repair using meniscal arrow. Materials and Methods : Between May 1997 and Aug 1998, we repaired 22 tom menisci in 22 patients using meniscal arrows. There were nineteen males and three females with an average age of 27 years. There were longitudinal tear in 14 cases, Bucket-handle tear were 7 cases and horizontal tear was in 1 case. In 22 meniscus tears, 16 cases were associated with anterior cruciate ligament tear. Average number of meniscal arrow that was used were 2.5(ranged 1 to 4). Average follow-up period was 14.7 months(ranged 6 to 22 months). We evaluated the clinical results by the Tapper and Hoover's grading system. Results : There were excellent in 16 cases, good in 4 cases and fair in 2 cases on the clinical results. At the last follow up, the range of the motion of the knee joint were average 135 degrees(ranged 125 to 140 degrees). Mean time elapsed for meniscal repair were 25 minutes(ranged 15 to 40 minutes). Conclusion : Meniscal arrow has many advantages such as short operative time, easy fixation technique, and less neurovascular injury. We think that arthroscopic meniscal repair using meniscal arrow is effective treatment method in selected patient who have longitudinal, bucket-handle tear at the posterior hom associated with anterior cruciate ligament tear.
Purpose: This study evaluated the clinical outcomes of debridement arthroplasty using the posteromedial approach in elbow joints with pain and bony limitation of motion. Materials and Methods: This study involved 16 elbows in 16 patients with pain and bony limitation of motion, which were treated by debridement arthroplasty using the posteromedial approach from March 2005 to March 2008. The mean follow up period was 27.6 (13~52) months. The clinical outcomes were analyzed using the Visual Analogue Scale(VAS) for pain scale, the preoperative and postoperative range of motion and the Mayo Elbow Performance Scores(MEPS). Results: The VAS was decreased significantly from a preoperative mean of 4.5 to a postoperative mean 1.1 (p<0.001). The average arc of motion improved significantly from $61.6 (0~90)^{\circ}$ preoperatively to $109.4 (80-120)^{\circ}$ postoperatively (p<0.001). The MEPS also improved significantly from 59.4 to 85.6 postoperatively (p<0.001). There were no complications, such as hematoma and elbow instability. Conclusion: Debridement arthroplasty using the posteromedial approach is a useful surgical procedure in the elbow joint with pain and bony limitation of motion, where all compartments can be debrided, the ulnar nerve can be manipulated easily and damage to the medial collateral ligament can be minimized.
