Background: In this study, the traditional “Anatomical Landmark-Distance Method (AL-DM)” in the formation of joint line (JL) was compared with “Adductor Tubercle-Ratios method” (AT-RM), and the effect of reestablishment of JL on clinical and functional outcomes were evaluated. Materials and methods: 16 revision total knee arthroplasties (rTKAs) were performed by using “AT-RM” (group 1) and 16 rTKA by using “AL-DM” (group 2) in our clinic between 2015 and 2018. The data were prospectively collected and a total of 32 knees of 31 patients were analyzed. At the final follow-up, knee functions were evaluated by using Knee Society Score (KSS) knee and function, Western Ontario and McMaster Universities Arthritis Index (WOMAC) scores, Short Form-36 (SF-36) questionnaires and physical examinations. Results: Postoperative flexion arc was higher in Group 1. KSS knee and function scores were better in group 1. In group1, JL was reestablished successfully in all revision rTKAs in terms of ATJL and the tibial tubercle TT-JL ratios. The improvement in KSS knee and function scores and WOMAC scores were also better in group 1. Measurements showed that the improvement in KSS scores increased as AT-JL and TT-JL distances approached the calculated values. Conclusion: “AT-RM” was shown to be superior to the traditional distance method in terms of JL reestablishment. Functional results and patient satisfaction increased when JL was reestablished.

Objective. The aim of this study was to compare the clinical and radiological results of Mau osteotomy and Scarf osteotomy with a modified McBride procedure to patients with moderate to severe hallux valgus deformity.Methods. The study included 40 feet which patients were separated into 2 groups followed up for 5 months. Scarf osteotomy was applied to 20 patients including 16 females and 4 males (Scarf group)) and a Mau osteotomy to 20 patients including 17 females and 3 males (Mau group). Radiological measurements were taken preoperative, postoperative and at the final follow-up examination of the hallux valgus angle (HVA), intermetatarsal angle (IMA), distal metatarsal articular angle (DMAA), metatarsocuneiform angle (MCA), the 1st metatarsophalangeal joint congruity, 1st metatarsal length, fibular sesamoid subluxation rate. Clinical evaluation was made according to the American Orthopaedic Foot and Ankle Society (AOFAS) and the severity of pain was assessed with the visual analog scale (VAS).Results. There was no difference between the groups in term of the mean HVA, IMA, MCA and DMAA values in preoperative and postoperative measurements. A significant improvement was determined in all the angle values in Scarf and Mau group (p < 0.001). A significant increase in DMAA and shortening in the metatarsal length were determined in Mau group compared to Scarf group (p < 0.001). An improvement in joint congruity was seen in the goups (p < 0.001). There was a significant improvement in term of the AOFAS and VAS values in the groups (p < 0.001).Conclusion. Scarf and Mau osteotomies can provide the desired level of improvement in the short-term follow-up results of moderate to severe hallux valgus deformity, taking into consideration the clinical importance that complications are not formed.

No consensus has been reached in the treatment of Frieberg disease. Our aim was to evaluate medium- to long-term results of patients with advanced Freiberg disease managed with extensor digitorum brevis tendon interpositional arthroplasty. There were 24 patients (19 females, 5 males) managed with interpositional arthroplasty for advanced Freiberg disease between 2003 and 2015. The mean follow-up was 133.8 (range, 60-198) months. According to Smillie classification, there were 4 grade 3, 13 grade 4, and 7 grade 5 patients. Patients were evaluated preoperatively and at the final follow-up with the American Orthopaedic Foot & Ankle Society (AOFAS) score and metatarsophalangeal joint range of motion and postoperatively with visual analog scale (VAS) and subjective satisfaction evaluation. Joint space was evaluated on x-rays. Mean AOFAS score increased (53.9 to 80.3, P = .001). Eight patients had excellent, 14 had good, and 2 had fair scores. A significant increase was found in dorsiflexion (38.1° [24°-52°] vs 55.3° [34°-65°]; P = .001) and plantarflexion (19.0° [10°-28°] vs 28.6° [19°-39°]; P = .001). Narrowing of the joint space was not seen in any patient, but expansion was determined in all patients (0.39 [0.35-0.47] vs 0.44 [0.41-0.47] cm; P = .002). Of the patients, 9 were very satisfied, 12 were satisfied, 2 were moderately satisfied, and 1 was dissatisfied. The mean postoperative VAS pain score was 1.7 ± 0.9 (0-4). After a minimum 5-year follow-up, most patients with Freiberg disease managed with interpositional arthroplasty using the extensor digitorum brevis tendon had excellent to good functional results with a widening of the joint space. Level IV, retrospective case series.

The aim of this study was to evaluate the success of the all-inside repair technique for medial bucket-handle meniscus tear (BHMT) and the factors affecting healing. A total of 36 patients with BHMT who were operated between 2012 and 2018 and completed final follow-up examinations were included in the study. Functional evaluation was made with the International Knee Documentation Committee (IKDC) score, Lysholm score, and Tegner score. Healing was evaluated on magnetic resonance imaging (MRI) slices. The patients were evaluated with respect to the effect on healing of factors such as demographic data, body mass index (BMI), smoking status, anterior cruciate ligament tear reconstruction (ACLTR) applied at the same time as BHMT repair, and the tear being chronic or acute. The mean age of the patients was 28.6 ± 8.6 years (range,18–46 years), the mean follow-up period was 25.8 ± 13.9 months (range, 13–59 months), and BMI was mean 25.6 ± 3.5 kg/m2 (range, 20.1–30.5 kg/m2). The meniscus tears were acute in 16 (44.4%) patients and chronic in 20 (55.6%). ACLTR was applied together with BHMT repair in 25 patients. The hybrid technique, as the outside-in technique in addition to the all-inside technique, was applied to 12 (33.3%) patients, where there was seen to be extension to the anterior horn. The failure rate was determined as 27.8% according to the postoperative MRI evaluation and the Barrett criteria. No positive or negative statistically significant effect on healing was determined of chronic BHMT or of simultaneous application of ACLTR (p = 1.00 and 0.457, respectively). Cigarette smoking and high BMI were determined to have a statistically significant negative effect on healing (p = 0.026 and 0.007, respectively). In conclusion, it can be seen that the success of the all-inside technique for BHMT remains controversial. Due to the features of the application, it can be used in meniscus tears of the posterior horn only. In the current study, with the success rate of 72.2% of the all-inside technique in meniscus body tears, it was seen that a high success rate could not be achieved.
