Comparing Clinical Outcomes Following Single and Double High Tibial Osteotomy
Background
Why this project was needed
High tibial osteotomy (HTO) is a joint-preserving procedure for younger patients with medial compartment knee osteoarthritis and varus malalignment. Both single (opening or closing wedge) and double (biplanar) HTO techniques are performed at GSTT, but a formal comparison of clinical and radiographic outcomes between these approaches in our patient cohort had not been undertaken. Comparing pre- and post-operative limb alignment radiographs with functional outcome scores allows assessment of the accuracy and clinical effectiveness of each technique.
Aims
What the project set out to achieve
To compare clinical and radiological outcomes of single versus double high tibial osteotomy in patients treated at GSTT between 2017 and 2023.
Objectives
Specific measurable steps
- Identify all patients who underwent tibial osteotomy under Mr Khakha between 2017 and 2023.
- Measure pre- and post-operative mechanical axis on full leg length films.
- Record standardised clinical outcome scores (KOOS, Oxford Knee Score) at follow-up appointments.
- Compare correction accuracy, complication rates and patient-reported outcomes between single and double osteotomy techniques.
