PURPOSE To compare the outside-in transtibial lateral and medial approaches for posterior cruciate ligament (PCL) reconstruction regarding the guidewires and popliteal artery integrity. METHODS Twenty-two human cadaveric knees were used. A PCL tibial aimer was arthroscopically placed within the PCL footprint through the anteromedial portal for the medial approach and through the anterolateral portal for the lateral approach. For the medial approach, the drill guide was introduced through the anteromedial tibial cortex and the guidewire was advanced with the reamer beyond the posterior tibial cortex. For the lateral approach, the drill guide was introduced through the anterolateral tibial cortex and the guidewire was advanced with the reamer beyond the posterior tibial cortex. After this, the knee was dissected. The depth distance (DD) was defined as the distance between the popliteal artery and the tibial posterior cortex projected at the tibial level at which the guidewire intersected or passed by the artery. The guidewire travel distance was calculated as the distance the guidewire had to advance beyond the tibial cortex to intersect the popliteal artery or pass by it. RESULTS With the medial approach, the popliteal artery was intersected in all knees with a mean DD of 12.20 mm and a mean guidewire travel distance of 15.90 mm. With the lateral approach, the popliteal artery was not intersected in any knee; its mean medial distance from the artery was 4.8 mm at a DD of 10.05 mm. There was a significant difference in the popliteal artery intersection incidence and DD between both groups (P < .0001 and P = .0003, respectively). CONCLUSIONS The transtibial lateral approach for PCL reconstruction was a safer method than the medial approach regarding popliteal artery injury by a guidewire. CLINICAL RELEVANCE This study presents a slight modification of the most frequently used PCL reconstruction technique, intending to minimize guidewire injury to the popliteal artery.

Objective to evaluate the results from surgery with computer-assisted navigation in cases of total knee arthroplasty. Method a total of 196 patients who underwent total knee arthroplasty with computer-assisted navigation were evaluated. The extension and flexion spaces (gaps) were evaluated during the operation and the alignment after the operation was assessed. The Knee Society Score (KSS) questionnaire for assessing patients function was applied preoperatively and postoperatively after a mean follow-up of 22 months. Results in all, 86.7% of the patients presented good alignment of the mechanical axis (less than 3° of varus or valgus in relation to the mechanical axis) and 96.4% of the patients presented balanced flexion and extension gaps. Before the operation, 97% of the patients presented poor or insufficient KSS, but after the operation, 77.6% presented good or excellent KSS. Conclusion the navigation system made it possible to achieve aligned and balanced implants, with notable functional improvement among the patients. It was found to be useful in assessing, understanding and improving knowledge in relation to performing arthroplasty procedures.

Objective The objective of this study is to evaluate the results and effectiveness of the technique of meniscal repair type all-inside using Fast-Fix device. Methods A retrospective cohort study evaluating 22 patients with meniscal surgery between January 2004 and December 2010 underwent meniscal repair technique for all-inside with the Fast-Fix device with or without ACL reconstruction. Function and quality of life outcomes were chosen by the IKDC and Lysholm score, before and postoperatively, and reoperation rates, relying to the time of final follow-up. Statistical analysis was performed using the Students t test. Results The mean follow-up was 59 months (16–84). The Lysholm score showed 72% (16 patients) of excellent and good results (84–100 points), 27% (6 patients) fair (65–83 points) and no cases classified as poor (<64 points). According to the IKDC: 81% (18 patients) of excellent and good results (75–100 points), 18% of cases regular (50–75 points) and no patient had poor results (<50 points). There were no failures or complications. Conclusion The technique of meniscal repair type all-inside using the Fast-Fix device is safe and effective for the treatment of meniscal lesions in the red zone or red-white with or without simultaneous ACL reconstruction, with good and excellent results in most patients Level 4 Study.

Anatomic posterolateral corner reconstruction reproduces 3 main structures: the lateral collateral ligament, the popliteofibular ligament, and the popliteus tendon. The LaPrade technique reproduces all 3 main stabilizers. However, it requires a long graft, limiting its indication to clinical settings in which allograft tissue is available. We propose a surgical procedure that is a modification of the LaPrade technique using the same tunnel placement, hamstring autografts, and biceps augmentation when necessary. It relies on artificial graft lengthening provided by the loop of the suspensory fixation device fixed at the anterior tibial cortex. The final reconstruction reproduces the popliteus tendon with the bulkiest end of the semitendinosus; the popliteofibular ligament with a strand of the semitendinosus and a strand of the gracilis; and the lateral collateral ligament with a strand of the semitendinosus and a strand of the gracilis, which can also be augmented with a biceps strip.

PURPOSE: Compare the clinical outcomes of the anteromedialization tibial tubercle osteotomy (TTO) combined with medial patellofemoral ligament reconstruction (MPFLR) versus MPFLR alone for the treatment of recurrent patellar instability (RPI) in patients with TT-TG 17 to 20 mm presenting its mid-term outcomes. METHODS: From January 2008 to August 2013, skeletally mature patients with RPI and TT-TG 17-20mm were quasirandomized into two groups: TTO combined with MPFLR (TTO+MPFLR) or MPFLR alone (MPFLRa). Quasirandomization: both interventions were explained to the patients and they chose which one to be submitted. Subjects were evaluated for patellar tracking lateralization, patellar glide, apprehension test, increased femoral anteversion, Caton index, trochlea dysplasia by Dejour classification, TT-TG, Kujala, IKDC, Lysholm and Tegner. RESULTS: Forty-two patients composed the study. TTO+MPFLR group was comprised of 18 patients and MPFLRa group was comprised of 24 patients. Demographics between groups were not significantly different related to age, gender, side, and cartilage lesion. Results are presented comparing TTO+MPFLR and MPFLa, respectively, as follows. Follow-up: 41.33±10.26, 40.5±11.63 months, p=0.81. Patellar tracking lateralization preoperatively: 3.33±0.84, 3.25 ±0.67, p=0.182. Patellar tracking lateralization postoperatively: 1±0, 1.33±0.48, p=0.006. Patellar glide and apprehension test preoperatively: All patients had a positive apprehension test or a patellar luxation at the patellar glide test rated as grade 4 before surgery. Patellar glide postoperatively: 1.17±0.38, 1.21±0.41, p=0.734. Apprehension test postoperatively: none. Increased femoral anteversion: 6%, 25%, p=0.9. Caton index preoperatively: 1.12±0.14, 1.12±0.11, p=0.97. Caton index postoperatively: 1±0.08, 1.12±0.11 (the same preoperatively), p=0.0012. TTO+MPFLR patients submitted to concurrent tibial tubercle distalization: 44%. Trochlea dysplasia: no significant difference between groups, p=0.67. TT-TG preoperatively: 18.5±1.24, 18.04±1.12, p=0.16. TT-TG postoperatively: 10.55±0.83, 18.04±1.12 (the same preoperatively), p<.001. No significant difference was seen International Society of Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine 11 th Biennial ISAKOS Congress • June 4-8, 2017 • Shanghai, China ISAKOS
