- Purpose
To evaluate the radiologic and clinical outcomes of a minimally invasive technique using the tarsal sinus approach in the management of Sanders type III, joint depressive type calcaneal fractures.
Materials and Methods
Between July 2011 and September 2019, data of 29 patients who underwent a minimally invasive procedure with the sinus tarsi approach for Sanders type III joint depressive intra-articular calcaneal fractures, and were followed up for more than 1 year were analyzed. We evaluated the radiologic outcomes by assessing the radiologic parameters (Böhler angle, Gissane angle, calca-neal length, calcaneal height, calcaneal width). We also evaluated the clinical outcomes based on the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and the complications associated with the technique.
Results
The radiological results showed an improvement in the Böhler angle from 2.5° to 18.6° and the Gissane angle from 132.4° to 119.1° after the operation. The mean AOFAS score during the clini-cal evaluation was 79.5. We observed 13 cases of posttraumatic arthritis, 1 case of subtalar arthrodesis, and no case of wound complication.
Conclusion
Minimally invasive technique for Sanders type III joint depressive calcaneal fractures resulted in relatively satisfactory radiologic and clinical outcomes. Open reduction and internal fixation through the sinus tarsi approach reduce complications including wound problems. This approach offers satisfactory results without long-term complications.

- Purpose
This study attempted to study the intra-articular changes due to intramedullary nailing through the suprapatellar approach by evaluating the joint cartilage damage and presence of foreign bodies through a comparison of the pre- and post-operative status evaluated by knee arthroscopy.
Materials and Methods
This retrospective study analyzed fifteen patients who underwent intramedullary nailing through the suprapatellar approach for proximal tibial shaft fracture from January 2017 to March 2020. The condition of the joint cartilage and the presence of foreign substances in the patellofemoral joint were evaluated. The cartilage status of the patellofemoral joint was evaluated using the International Cartilage Repair Society (ICRS) grading system. Data from the ICRS grading and the visual analogue scale (VAS) scores of the femoral and patellar cartilage were compared to each independent variable surveyed.
Results
All the intra-articular structures before nailing were normal. In all cases after nailing, articular cartilage damage of the patellofemoral joint and intra-articular debris were observed. The average VAS score was 0.6 (0-1) before surgery and 2.27 (0-4) after surgery. There were no statistically significant differences except for the correlation in the diameter of the tibia nail and femoral ICRS grade (p=0.001) and the damage to the cartilage was greater in the femoral cartilage than that to the patella (p=0.001).
Conclusion
Intra-articular damage appears to be unavoidable in suprapatellar nailing. Further research is needed on the long-term effects of intra-articular damage and on methods to reduce this damage.
