Posterior root repair with high tibial osteotomy improves radiological and clinical outcomes despite greater medial meniscus extrusion: A comparison of transtibial and all-inside techniques

Abstract
Purpose
To evaluate whether the transtibial pullout (TTP) or all-inside suture (AIS) technique provides superior radiological and clinical outcomes in patients undergoing medial meniscus posterior root (MMPR) repair combined with high tibial osteotomy (HTO) over a 24- to 48-month follow-up.
Methods
This retrospective cohort study analysed 54 knees in 52 patients who underwent MMPR repair with HTO between April 2018 and March 2022. The TTP technique was used until March 2020, after which the AIS technique was performed thereafter. Inclusion criteria were MMPR repair with HTO within 3 months of symptom onset, age 50-70 years, and ≥2 year postoperative follow-up. Exclusion criteria were non-index limb symptoms and unrelated postoperative conditions. Ultimately, 28 knees were assigned to the TTP group and 26 to the AIS group. Radiological, arthroscopic and clinical outcomes were evaluated at a uniform follow-up interval (TTP: 37.1 ± 8.6 months; AIS: 33.8 ± 9.1 months). Medial meniscus extrusion (MME) was quantified using the modified Costa method. Appropriate statistical tests were applied for intra- and inter-group comparisons.
