Summary
Total knee replacement after high tibial osteotomy shows excellent outcomes, with significant pain reduction and improved function. Previous osteotomy does not adversely affect cemented posterior cruciate retaining total knee replacement results.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- High tibial osteotomy (HTO) is a common procedure for knee osteoarthritis.
- Assessing the long-term outcomes of total knee replacement (TKR) following HTO is crucial for patient management.
Purpose of the Study:
- To evaluate the clinical results of TKR performed after HTO.
- To determine if prior HTO impacts TKR outcomes.
Main Methods:
- Retrospective review of 95 TKRs performed after HTO between 1980 and 1995.
- Analysis of patient demographics, preoperative diagnoses, and surgical details.
- Long-term follow-up assessing Knee Society scores, pain, and radiographic findings (radiolucencies).
Main Results:
- Significant improvement in Knee Society knee scores (38.1 to 87.6) and pain relief (86.2% no pain).
- Tibial radiolucencies observed in 12.8% of knees, with only one revision surgery.
- Preoperative flexion contracture and prior surgeries correlated with diminished postoperative motion.
Conclusions:
- TKR after HTO yields clinical results comparable to primary TKR.
- Prior HTO does not negatively influence the outcomes of cemented posterior cruciate retaining TKR.
