“…Second, it is possible that alignment changes over time after OWHTO 28 ; however, we included cases with radiographs obtained from 6 weeks to 3 months after operation, during which time changes in alignment would be minimal. 28 Some authors reported progressive changes in alignment by evaluating serial radiographs, but the difference of alignment (weight-bearing line) was only 1.5% at 6 months after operation. 28 Third, there is little information about the effects of abnormal KJLO on knee kinematics, functional outcomes, and long-term survival 29 ; of note, the clinical scores during this short follow-up were not significantly different between the two groups with or without abnormal -post KJLO.…”

The aim of this study was to evaluate which lower extremity alignment (knee and ankle joint) parameters affect knee joint line obliquity (KJLO) in the coronal plane after open wedge high tibial osteotomy (OWHTO). Overall, 69 knees of patients that underwent OWHTO were evaluated using radiographs obtained preoperatively and from 6 weeks to 3 months postoperatively. We measured multiple parameters of knee and ankle joint alignment (hip-knee-ankle angle [HKA], joint line height [JLH], posterior tibial slope [PS], femoral condyle-tibial plateau angle [FCTP], medial proximal tibial angle [MPTA], mechanical lateral distal femoral angle [mLDFA], KJLO, talar tilt angle [TTA], ankle joint obliquity [AJO], and the lateral distal tibial ground surface angle [LDTGA]; preoperative [-pre], postoperative [-post], and the difference between -pre and -post values [-Δ]). We categorized patients into two groups according to the KJLO-post value (the normal group [within ± 4 degrees, 56 knees] and the abnormal group [greater than ± 4 degrees, 13 knees]), and compared their -pre parameters. Multiple logistic regression analysis was used to examine the contribution of the -pre parameters to abnormal KJLO-post. The mean HKA-Δ (-9.4 ± 4.7 degrees) was larger than the mean KJLO-Δ (-2.1 ± 3.2 degrees). The knee joint alignment parameters (the HKA-pre, FCTP-pre) differed significantly between the two groups ( < 0.05). In addition, the HKA-pre (odds ratio [OR] = 1.27, = 0.006) and FCTP-pre (OR = 2.13, = 0.006) were significant predictors of abnormal KJLO-post. However, -pre ankle joint parameters (TTA, AJO, and LDTGA) did not differ significantly between the two groups and were not significantly associated with the abnormal KJLO-post. The -pre knee joint alignment and knee joint convergence angle evaluated by HKA-pre and FCTP-pre angle, respectively, were significant predictors of abnormal KJLO after OWHTO. However, -pre ankle joint parameters were not significantly associated with abnormal KJLO after OWHTO.

“…Sixth, the time point of radiographic and/or functional outcome evaluation varied among the included studies. Alignment can change over time, hence, the different follow-up period and the time point of the radiographic evaluation may affect the result 39) including the functional outcome; substantial heterogeneity of included studies is the inherent limitation of meta-analyses. Finally, the long-term result was not investigated.…”
