Purpose: The purpose of this study is to evaluate the results of Kidner procedure combined with medial displacement calcaneal osteotomy (MDCO) in patients with the symptomatic accessory navicular with hindfoot valgus. Materials and Methods: From January 2014 to January 2019, fifteen patients (15 cases) who had undergone a Kidner procedure combined with MDCO for symptomatic accessory navicular with hindfoot valgus were included. Their mean age was 36.3 years old (19~61 years old) and there were 6 males and 9 females. The clinical results were evaluated using visual analogue scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score, and postoperative subjective satisfaction. The radiographic results were evaluated using the talonavicular coverage angle and the anteroposterior talo-first metatarsal angle, the lateral talo-first metatarsal angle, the calcaneal pitch angle, and the hindfoot alignment angle. The postoperative complications were also evaluated. Results: The VAS and AOFAS midfoot scores continuously improved until 12 months after surgery. Subjective satisfaction after surgery was excellent in 10 cases and good in 5 cases. The hindfoot alignment angle significantly changed after surgery. Pain due to lateral impingement disappeared in five patients, and persisted in one patient. Five patients complained of irritation caused by their fixation devices, and all the symptoms improved after removal of the fixation devices. Conclusion: Kidner procedure combined with MDCO in patients with the symptomatic accessory navicular with hindfoot valgus showed good clinical results with satisfactory correction of hindfoot valgus. In particular, the clinical results showed continuous improvement until 12 months after surgery.

The osteochondroma is a cartilage-capped exostosis resulting from an error in the regulation of normal chondrocyte proliferation and maturation that leads to a normal bone growth. Although exostoses are benign lesions, they are often associated with characteristic progressive skeletal deformities and may cause clinical symptoms. Surgery can prevent progression and provide correction for certain deformities. We experienced a rare case of solitary osteochondroma in a 21-year-old male which caused the valgus deformity of the ankle.

Purpose: The aim of this research is to determine whether there is a significant correlation between the angle of the hallux valgus and dorsi-flexion of the 1st metatarsophalangeal joint (1st MPJ) as a physical factor that has a significant influence on healthy human walking. Methods: The subjects of this research were 65 female adults (130 feet) and the methods used included recording of real measurements and conducting a questionnaire. The acquired data is analyzed by the 'Simple Pearson Correlation Analysis' and 'Repeated Measures Analysis' methods. Results: The research result shows that the left area of -0.74706 and the right area of -0.76 have a relatively high negative correlation (p<0.00). Also, after conducting the 'Repeated Measures Analysis of Variance' of the angles of the hallux valgus and dorsi-flexion of the 1st metatarsophalangeal joint (1st MPJ), the result also shows that the left and right areas of -0.75 have a relatively high negative correlation. Conclusion: The present study was performed for the identification of a significant correlation between the angle of the hallux valgus and dorsi-flexion of the 1st MPJ. From the results of this study, we confirmed that there is a clear tendency for the average distribution rates of Hallux Valgus and Hallux Rigidus (Hallux Limitus) of women to show a higher increase in proportion to age.

Posterolateral instability of the knee occurs more commonly in association with an injury to anterior and posterior cruciate ligament and combined injuries are severe injuries that result in significant functional instability and articular cartilage degeneration. Reconstruction of the anterior and posterior cruciate ligament without an appropriate treatment of posterolateral corner injury result in failure of the reconstructed cruciate ligaments. Meticulous physical examinations, imaging studies, lower limb alignment and gait pattern should be evaluated. Acute grade III isolated or combined injury of the posterolateral corner is best treated within three weeks by direct repair, or augumentation, or reconstruction. The appropriate surgical method or combined methods are selected among the several methods of posterior and posterolateal reconstruction, and all injuried posterolateral and cruciate ligament structures are anatomically reconstructed simultaneously or by stages. If a varus alignment and varus thrust is disclosed in chronic posterolateral instability of knee, soft tissue reconstructions laterally are highly unlikely to be able to correct tile problem. It is appropriate that valgus osteotomy should be done before soft tissue reconstruction and reevaluate the posterolateral instability about 6 months later.

The purpose of this study was to determine whether gender differences existed in knee valgus kinematics in college students when performing a vertical drop landing. The hypothesis of this study was that females would demonstrate greater knee valgus motion. These differences in knee valgus motion may be indicative of decreased dynamic knee joint control in females. This study compared the initial knee valgus angle and maximum knee valgus angle at the instant of impact on vertical drop landings between healthy men and women. In this study, 60 participants (30 males, 30 females) dropped from a height of 43 cm. A digital camera and two-dimensional video motion analysis software were used to analyze the kinematic data. There was significant difference in the mean knee valgus angle at initial contact landing between the two groups (Mean=$7.88^{\circ}$, SD=$4.24^{\circ}$ in males, Mean=$12.93^{\circ}$, SD=$2.89^{\circ}$ in females). The range of knee valgus angle on landing (Mean=$3.25^{\circ}$, SD=$5.72^{\circ}$ in males, Mean=$11.44^{\circ}$, SD=$6.39^{\circ}$ in females) was differed significantly (p<.05). The maximal angle of knee valgus on landing (Mean=$10.91^{\circ}$, SD=$6.89^{\circ}$ in males, Mean=$24.25^{\circ}$, SD=$6.38^{\circ}$ in females) was also differed significantly (p<.05). The females landed with a larger range of knee valgus motion than the males and this might have increased the likelihood of a knee injury. The absence of dynamic knee joint stability may be responsible for increased rates of knee injury in females. No method for accurate and practical screening and identification of athletes at increased risk of ACL injury is currently available to target those individuals that would benefit from neuromuscular training before sports participation.

Tibial eminence fracture is caused by distortion, excessive flexion and extension, varus and valgus injury of the knee joint in the form of avulsion fracture. A failure over the exact anatomical reduction of fragment can lead to instability and limitation of joint motion. Recently, a variety of arthroscopic assisted reduction and fixation technique have been used. In the tibial eminence fracture, we created an arthroscopic pull-out wire fixation technique using a cannulated screw that is easy and more convenient than in the conventional technique. So we report this technique with a review of current literatures.

PURPOSE: This study sought to evaluate muscle activity and foot pressure during gait, and balance in female college students with genu valgum. METHOD: Participants were assigned based on their Q-angle to genu valgum group greater than 20° (GVG, n = 12), unilateral genu valgum group greater than 20° (UVG, n = 11), and control group (CON, n = 13). All subjects were evaluated for balance (Trace length, C90 area, C90 angle, and the Romberg test), muscle activity (gluteus medius; GM, tensor fasciae latae; TFL, vastus medialis; VM, vastus lateralis; VL, biceps femoris; BF, gastrocnemius; GCM and tibialis anterior; TA) and foot pressure (F/F ratio, R/F ratio, Hallux, 2~5 toe, 1st MT, 2~4 MT, 5th MT, Midfoot, M/heel, and L/heel) during gait. RESULTS: Romberg test showed significantly increased loss of balance in the UVG group compared with the CON. In the forward position, the imbalance was significantly increased in the UVG and GVG groups compared to the CON. Muscle activity of VL, GCM, and TA significantly increased in the GVG group compared with the CON. Static foot pressure, 1st MT significantly increased in the GVG compared to the CON group. The 5th MT significantly decreased in the CON compared with the GVG group. The R/F ratio significantly decreased in the GVG compared to the CON group. In dynamic foot pressure, the 2~5 toe significantly increased in the GVG compared with the UVG group. The left 5th MT significantly decreased in the UVG compared with the CON and GVG groups. CONCLUSION: These results indicate that genu valgum has a negative effect on balance, muscle activity, and foot pressure during gait in female college students.

Purpose: To evaluate the clinical and radiographical results of arthroscopic meniscectomy in patients aged over 50 with minimum 3-year follow-up. Materials and Methods: Of the patients who had undergone arthroscopic meniscectomies between Dec. 1997 and Dec. 2003, 36 patients(36 knees) were available for retrospective evaluation. The average age at the time of surgery was 56.4 years and the mean follow-up period was 63 months. According to the Kellgren-Lawrence classification, grade I change were noted in 16 patients, II in 12, III in 6 and IV in 2. According to Outerbridge classification, grade I articular lesions were noted in 16 patients, II in 10, III in 7 and IV in 3. Postoperative Lysholm score, patient s subjective satisfaction and radiographic changes were evaluated retrospectively. Results: Twenty-four patients(66.7%) were good or excellent for the Lysholm score and 26 patients(72.2%) were satisfied at final follow-up. Tibiofemoral angle was changes from mean valgus 3.9 degrees to mean valgus 2.6 degrees and 22 patients(61.1%) showed the progression of osteoarthritic changes. Conclusion: The satisfactory results could be obtained in 72.2% of patients aged over 50 with a minimal follow-up of 3 years after arthroscopic meniscectomy. The results tended to be worse in patients with moderate or severe tibiofemoral osteoarthritic changes or with articular cartilage lesions.

Purpose: The purpose of the study was to evaluate the usefulness and the stability of the superficial medial collateral ligament (MCL) release in posterior medial meniscus root repair. Materials and Methods: We compared 20 patients who underwent posterior medial meniscus root repair with superficial MCL preserved (PM) and 32 patients who underwent posterior medial meniscus root repair combined with superficial MCL release (RM) from April 2006 to September 2010. We excluded the patients combined with other surgery. To evaluate the postoperative valgus instability in RM group, we examined direct tenderness on MCL insertion, the subjective feeling of instability and valgus stress test at 3 months and 1 year follow-up. We compared the tourniquet time between PM group and RM group, and the clinical results were assessed by Lysholm score and International Knee Documentation Committee (IKDC) for the usefulness. Results: All patients had no clinically significant complication related to the superficial MCL release. Three months and 1 year follow-up, there were no positive tenderness test, no subjective symptoms and no significant increase of valgus instability although 5 patients examined grade I valgus instability. The mean tourniquet time was $41.3{\pm}12.7$ minutes in RM group and $53.5{\pm}13.6$ minutes in PM group. There was a significant difference in the tourniquet time between the two groups (P<0.05). Average Lysholm score was $56.8{\pm}5.5$ (range, 44-70) preoperatively and $85.1{\pm}5.8$ (range, 77-94) postoperatively in PM group, and was $56.2{\pm}5.4$ (range, 45-67) preoperatively and $87.4{\pm}3.9$ (range, 82-95) postoperatively in RM group (P<0.001). No significant difference of Lysholm score was found in both groups (P<0.05). Average IKDC scores was $42.6{\pm}3.9$ (range, 30-53) preoperatively and $77.2{\pm}6.3$ (range, 68-92) postoperatively in PM group, and was $42.7{\pm}5.7$ (range, 30-53) preoperatively and $89.6{\pm}2.9$ (range, 84-95) postoperatively in RM group (P<0.05). There was also no significant difference of IKDC score in both groups (P<0.05). Conclusion: The superficial MCL release in posterior medial meniscus root repair is useful to gain a wide surgical field and reduces the tourniquet time and does not lead to postoperative valgus instability. It can be considered clinically useful and safe procedure in medial meniscus posterior root repair.
