title: Physeal sparing arthroscopic fixation of displaced tibial eminence fractures: a new surgical technique.
abstract: We describe a novel physeal sparing arthroscopic technique for anatomic suture refixation of tibial eminence fractures and assess the mid-term results of six consecutive patients (McKeever type II n = 2, III n = 3 and IV n = 1). The mean follow-up was 5 +/- 2 years. Five of six patients were painfree. All patients returned to their preinjury sport level. Mean passive ipsilateral and contralateral flexion was 143 degrees +/- 5 degrees. The IKDC score was A in five and B in one patients. The mean Lysholm score was 97 +/- 3%. The median Tegner score was 8 (range 6-9) preinjury and at follow-up. The mean Total Knee Society score was 197 +/- 4 points. ACL laxity (KT-1000 134 N) showed a side-to-side difference of 2 +/- 2 mm. Two of six patients underwent a tibial screw removal under local anaesthesia. No loss of reduction or grossly physeal disturbance was observed. The reported surgical technique showed excellent to good clinical and radiological results and may be a physeal sparing alternative to previously described procedures.
