Problem: The anatomically shaped pcl (ESKA) total hip replacement has a porous coating of the proximal stem and the cup to allow for bony ingrowth. The tip of the stem is polished.
Method: We report the results of 96 THR 6.2 years (5.25-6.7) after implantation.
Results: There were no revisions during this period. One stem showed radiographic loosening at follow-up. There was stress-shielding in 9.4% in contrast to the concept of proximal fixation. Thigh-pain was found in 9.4%. One patient demonstrated disabling thigh-pain despite radiologic bony ingrowth. By drilling the femur distal to the tip of the stem a remarkable relief was achieved.
Conclusion: Despite numerous cases of stress-shielding (9.4%), bony ingrowth occurs in 97%. The tcl-THR performs sufficiently after 6 years of implantation.
