Summary: This study aimed to identify the most effective individualized method of quantifying lateralization of the tibial tubercle. The results showed that the (TT-TG)/TW index demonstrated the best diagnostic effectiveness, with the largest mean difference, highest diagnostic utility (as measured by AUC values), and excellent reliability.

Summary: In patients with patellar instability, lateral patellar maltracking with the knee extended can be largely attributed to either a shallow trochlear groove or a combination of patella alta and a lateral position of the tibial tuberosity. These relationships should be considered in both conservative and surgical treatment planning.

Summary: Medial open wedge high tibial osteotomy (MOWHTO) has an influence on TTTG, and the lateralisation of the tibial tuberosity can be reliably calculated using a mathematical formula.

Summary: The study found that MPFL reconstruction with soft tissue patellar fixation leads to significant improvement in knee function and low midterm redislocation rate. Patients with high-grade trochlear dysplasia should be considered for additional osseous correction.

Summary: This study introduced TT-rotational angle as a new anatomical parameter with predictive value for patellar dislocation, which can be measured when the TT-TG distance is not clearly defined.

Summary: This study retrospectively analyzed a series of cases of 68 patients who underwent previous surgeries, and demonstrated that dTTO with MPFL-R surgery can effectively stabilize the patella, improve patient outcomes, but may also have some postoperative complications.

Summary: This study aimed to obtain normal patellofemoral measurements in a Chinese population and analyze sex and individual differences. Results showed that while there were significant differences in dimensional parameters and TT-TG distance between men and women, these differences disappeared after controlling for age, height, and weight. Using LASSO regression, four parameters were identified to accurately predict TT-TG distances.

Summary: This study aimed to investigate the influence of moderately increased TT-TG distance and patella alta on patient-reported outcomes (PROs) after MPFL reconstruction. The results showed that isolated MPFL reconstruction in the setting of moderately elevated TT-TG distance or patella alta was not associated with worse PROs in patients with relatively normal patellar tracking.

Summary: A comparison study was conducted to assess the clinical outcomes between MPFL reconstruction and MPFL reconstruction with TTO for patients with patellar instability and a TT-TG distance of 15 to 25 mm. The results showed no significant differences in clinical and radiological parameters, functional failure, or complications between the two groups. Subgroup analysis based on TT-TG distance also did not reveal any differences in clinical outcomes between the groups.

Summary: An excessively lateral tibial tubercle is a well-accepted risk factor for recurrent patellar dislocation. The TT-TG distance can be used as a threshold for deciding when to medialize the tibial tubercle, but an individualized index dividing the TT-TG distance by the trochlear width may be a more promising method, with a suggested cut-off value of 0.572.

Summary: This study aimed to investigate the effect of medial patellofemoral ligament (MPFL) reconstruction on patellar tracking and contact pressures in knees with mild patella alta. The results showed that MPFL reconstruction significantly reduced patellar lateral tracking at low flexion angles, decreased the maximum lateral pressure in mid-flexion, and increased the maximum medial pressure in mid-flexion. These findings suggest that MPFL reconstruction can improve patellar stability and reduce the pressure on lateral cartilage in knees with mild patella alta.

Summary: This study investigated the clinical outcomes of patients treated with a combination of distal femoral osteotomy and tibial tuberosity distalization osteotomy for patellar instability and patellofemoral pain. The results showed that restoration of patellofemoral alignment through surgery achieved good patient-reported outcome measures.

Summary: Bereiter trochleoplasty, often combined with MPFL reconstruction and/or tibial tuberosity transfer, achieves good clinical outcomes in patients with recurrent patellar instability and severe trochlear dysplasia, with low rates of re-dislocation and complications.

Summary: This study found a correlation between the volume and morphology of the patella and the volume of the trochlea in trochlear dysplasia, suggesting that patellar volume can be a determining parameter in the evaluation of TD. The technique used in this study can aid in prosthesis construction and more accurate surgical planning.

Summary: The study found that isolated anatomic MPFL reconstruction can achieve good clinical outcomes and patellofemoral stability, with a high rate of return-to-sport. However, it is unclear if the reconstructed MPFL has a contributory effect on reducing patellar height.
