The avulsoin fracture of the tibial intercondylar eminence can mechanically block full extension of the knee and cause a relative lengthening of the anterior cruciate ligament.
Therefore, its treatment is directed toward reattachment of loose fragment and achievement of some degree of joint congruity, rather than restoration of cruciate integrity.
The purpose of this study is to discuss the obstacles for reduction of fragment, and some effectiveness and problems in arthroscopic reduction and percutaneous mulatiple K-wi9res fixation.
The authors analyzed 20 cases of type Ⅲand typeⅣfractures of the tibial intercondyar eminence who were treated from Feb. 1991 to Feb. 1995.
@ES The survey is summarized as follows;
@EN 1. The method of arthroscopic percutaneous multiple K-wires fixation provided relatively easy reduction and stable fixation using by two kinds of technique in type ⅢA and ⅢB.
2. The hmatoma of fracture site, transverse ligament and meniscus were obstacles for reduction of fragment.
3. In cases, we obtained bony union at about 12 weeks, but is showed extension loss due to prolonged external immobilization in 2 cases of adult, in 2 cases of type IV and 1 cases of type3 IV and 1 case of ado9lescent.
4. In child, we didn´t find any significant extension loss in spite of external immobilization and resulted excellent in almost all.
5. In conclusion arthroscopic percutaneous K-wire fixation is useful method in child, but not enough in adult and comminuted cases.
