슬관절 전치환술 후 굴곡장애에 대한 조기 강제 관절 굴곡

Abstract

Purpose: We evaluated restoration of range of motion(ROM) after manipulation under intravenous anesthesia in patients whose maximum flexion was less than 90 °at 2 weeks after total knee arthroplasty(TKA).

Materials and Methods: 136 knees of 108 patients who received TKA between January 1996 and December 2000 and followed up for more than 2 years were analyzed. The forceful manipulation underwent for 16 knees because whose maximum flexion was less than 90°after 2 weeks of TKA. Manipulation were done for 12 of 16 cases at 2 weeks after TKA and 4 cases after more than 3 months.

Results: 12 knees which were manipulated 2 weeks after TKA had a mean flexion 103±10.2°, 111±9.6°and 116±11.4°at immediate post-operation, 3 months and 2 years after TKA. In 4 knees manipulated more than 3 months after TKA, a mean flexion was 100±10.4°, 102±11.5°and 96±11.4°at immediate post-operation, 3 months after manipulation and 2 years after TKA. 120 knees with no manipulation had a mean flexion 115±13.7°at last follow-up. There was no difference of a mean flexion at last follow-up between group manipulation within 2weeks after TKA and group with no manipulation.

Conclusion: Manipulation under intravenous anesthesia performed 2 weeks after TKA if patients had less than 90°of flexion increased flexion of the operated knee without any serious complication.
