OBJECTIVE:
To summarize the biomechanical characteristics, diagnosis, and hip arthroscopic treatment of borderline developmental dysplasia of hip (BDDH) with Cam-type femoroacetabular impingement (Cam FAI).
METHODS:
The literature on BDDH with Cam FAI at home and abroad in recent years was extensively reviewed and analyzed.
RESULTS:
In patients with BDDH and Cam FAI, the femoral neck anteversion angle and femoral neck shaft angle increase, the pelvis tilts, and the acetabulum rotates, resulting in instability of the hip joint. In order to maintain the stability of the hip joint, the direction of biomechanical action of the hip joint has changed, which further affects the anatomical structures such as the proximal femur and acetabular morphology. BDDH with Cam FAI can be diagnosed clinically by combining lateral center edge angle, anterior center edge angle, and acetabular index. BDDH with Cam FAI can be effectively treated through arthroscopic polishing of the edges of the acetabular proliferative bone, excision of Cam malformations, and minimally invasive repair of the glenoid lip and cartilage of the hip joint.
CONCLUSION
Currently, there is no unified standard for the diagnosis and treatment of BDDH with Cam FAI. Minimally invasive treatment of the hip under arthroscopy can achieve good early- and medium-term effectiveness, and has certain advantages in repairing and maintaining the integrity of the glenoid lip and suturing/compression joint capsule. However, the long-term effectiveness needs to be further followed up to determine. The timing of surgery, intraoperative bone edge depth polishing, and joint capsule suturing/compression techniques also need to be further explored.

To investigate the surgical effect of hip arthroscopic labrum reconstruction. A retrospective study was performed on the clinical data of 12 patients who underwent hip arthroscopic labrum reconstruction in our department from September 2017 to February 2021 and were followed up for 5-46 months, with an average of 21.5 months. All the patients had a hip joint space of more than 2 mm, and Tonnis grade less than level Ⅱ. These 12 patients underwent arthroscopic debridement of hyperplastic synovium, femoral head and neck and/or acetabular osteoplasty, and labrum reconstruction using autograft iliotibial band or gracilis tendon. After the surgery, we conducted follow-up and data collection, recorded the satisfaction of the patients and occurrence of complications, as well as the cartilage lesion of hip joint observed under the arthroscopy. We compared the alpha angle of Dunn X-ray film, center-edge angle (CE angle) of AP X-ray film, modified Harris hip score (mHHS score), hip outcome score (HOS), international hip outcome tool 12 score (iHOT12 Score), and visual analogue scale (VAS scale) before and after the arthroscopic operation, to assess clinical symptom relief and joint function recovery. The 12 patients were followed up for 5-46 (21.5±12.8) months. The VAS scale were (5.3±2.5) and (2.5±1.4) before and after the surgery, showing significant decrease (P=0.018). The mHHS score were (60.6±22.2) and (83.1±5.8) before and after the surgery, showing significant increase (P=0.003). The patient satisfaction was high (7.8±2.0) (range: 0-10). None of the 12 patients had serious complications, revision surgery, or total hip replacement at the end of the last follow-up. Autologous tendon transplantation for reconstruction of acetabular labrum under arthroscopy can improve the clinical symptoms and joint function of patients with femoroacetabular impingement (FAI), which is a safe and effective treatment.

OBJECTIVE:
To compare the clinical outcomes and complications of hip arthroscopic treatment for femoroacetabular impingement (FAI) performed with either Inside-out or Outside-in approach.
METHODS:
The clinical date of 48 patients with FAI treated by hip arthroscopy surgery and follow-up from June 2016 to June 2019 were retrospectively analyzed. According to the different operative methods, the patients were divided into two groups. Inside-out group, from central compartment to peripheral compartment;Outside-in group, from peripheral compartment to central compartment. There were 14 males and 10 females in Inside-out group with an averageage of (39.8±7.6)years old, 13 males and 11 females in Inside-out group with an average age of (39.5±9.1)years old in Outside-in group. There was no significant difference in age, gender, body mass index, side, impingement type, medical history and follow-up time between the two groups. The complication occurrence rate, modified Harris hip score (mHHS)and nonarthritic hip score (NAHS) were compared between these two groups.
RESULTS:
The mHHs and NAHS scores of the two groups were significantly higher than those before operation, but there was no significant difference between the two groups (
CONCLUSION
Both hip arthroscopic surgery methods can obtain satisfactory clinical efficacy in the treatment of FAI, but the incidence of postoperative complications of Outside-in surgical method is lower. The out-side in method can be preferentially selected for the patients with the indications of operation.

BACKGROUND: The authors report the results of femoroacetabular impingement (FAI) treated with a surgical dislocation. METHODS: From April 2005 to May 2007, 15 FAI hips were treated with a surgical dislocation. The male/female ratio, mean age and mean symptom duration was 12/2, 35.8 years and 2.3 years, respectively. Radiographs and MR arthrograms were taken. The clinical evaluation involved changes in the pre- and postoperative Harris hip score (HHS). RESULTS: There were 12 hips (80%) with at least one structural abnormality in the radiographs, with 11 (79%) labral tears and 8 (73%) abnormally high angles in the MR arthrograms. We performed 15 osteochondroplasties, 12 labral repairs, 12 acetabuloplasty, and 3 debridements. The mean HHS improved from 76 to 93 points. Three non-unions of the trochanteric osteotomy sites were encountered as complications. CONCLUSIONS: Radiographs and MR arthrograms are important for making a proper diagnosis of FAI and planning treatment. A surgical dislocation can be used to treat FAI but further technical improvements will be needed for fixation of the greater trochanteric osteotomy sites.

OBJECTIVE:
To evaluate the clinical effects of tranexamic acid in arthroscope for femoroacetabular impingement.
METHODS:
Totally 34 patients (34 hips) with femoroacetabular impingement underwent hip arthroscopy from June 2016 to December 2018, were randomly divided into two groups named as tranexamic acid group and control group, 17 patients in each group. In TXA group, there were 10 males and 7 females, aged from 20 to 49 years old with an average of (32.1±7.6) years old;15 mg/kg TXA was intravenous drops before operation incision performed at 10 min. In control group, there were 11 males and 6 females, aged from 20 to 49 years old with an average of (30.9±6.2) years old;100 ml normal saline was intravenous drops before operation incision performed at 10 min. Introopertaive and total bloodloss between two groups were compared. Visual analogue scale (VAS) at 3 and 7 days after opertaion were used to evaluate pain relief of hip joint. Modified Harris Hip Score(mHHS) of hip joint at 3, 6, 9 and 12 weeks after oeprtaion were applied to evaluate clinical effects.
RESULTS:
All patients were obtained follow up over 12 weeks. Incision healed well without infection and deep vein thrombosis. There were no statistical difference in opertaion time bewteen two groups(
CONCLUSION
Preoperative application of tranexamic acid could effectively reduce blood loss in arthroscopy for femoroacetabular impingement, thereby improving surgical field of vision, reducing difficulty of surgical operation, which could promote early and rapid rehabilitation of hip function.

BACKGROUND:
Heterotopic ossification (HO) is a known complication of hip arthroscopy. We investigated incidence of HO after hip arthroscopy and determined whether revision for HO improved outcome.
METHODS:
A retrospective study was conducted on 242 patients (140 men and 102 women, mean age: 36.2 ± 9.5 years) who underwent hip arthroscopy for femoroacetabular impingement (FAI) between January 2016 and January 2018. The average follow-up period was 22.88 ± 11.74 months (range: 11-34 months). Thirteen (5.37%) cases of HO (six men and seven women, five left hips and eight right hips; mean age: 37.5 ± 4.7 years) were observed. Among them, four cases with HO with obvious pain symptoms and persistent non-remission underwent revision surgery to remove HO. Monthly follow-up was conducted. Visual analog scale (VAS), modified Harris Hip Score (mHHS), and non-Arthritis Hip Score (NAHS) were evaluated and compared between HO and non-HO patients. Independent sample t test, Mann-Whitney U test and the Chi-square test were used for inter-group comparisons. HO degree was evaluated using Brooker classification. Symptoms and function were evaluated before and after revision.
RESULTS:
A total of 242 patients were involved in this study. Thirteen cases (5.4%) had imaging evidence of HO. Nine (9/13) were classified as Brooker stage I, three (3/13) Brooker stage II, and one (1/13) Brooker stage III. HO was detected by ultrasonography as early as 3 weeks after operation. After primary surgery, the mHHS of the HO group and non-HO group increased by 13.00 (8.50, 25.50) and 24.00 (14.00, 34.50) points (Z = -1.80, P = 0.08), NAHS increased by 18.00 (9.50, 31.50) and 26.00 (13.50, 36.00) points (Z = -1.34, P = 0.18), and VAS decreased by 3.00 (2.00, 4.00) and 4.00 (3.00, 4.50) points (Z = -1.55, P = 0.12). Average follow-up time after revision was 9.00 ± 2.94 months; mHHS increased by 34.75 points (t = -55.23, P < 0.01) and NAHS by 28.75 points (t = -6.03, P < 0.01), and VAS decreased by 4 points (t = 9.80, P < 0.01). HO and non-HO patients were similar for demographic and surgical data, and clinical and functional scores.
CONCLUSION
HO incidence after arthroscopic treatment of FAI is similar to that found in previous studies. Most HO have no effect on clinical symptoms. Patients who undergo revision HO resection show improvement in pain and joint function.

Clinics in Orthopedic Surgery 2009;1(4):230-235
BACKGROUND: We wanted to investigate acetabular labral tears and their correlation with femoroacetabular impingement in patients with sports injury. METHODS: Among 111 patients who were diagnosed with the acetabular labral tears after arthroscopic treatment from January 2004 to December 2007, we selected 41 patients with sports injury. There were 12 cases of Taekwondo injury, 5 of golf injury, 4 of soccer injury, 3 of gymnastics injury, 2 of Hapkido injury, 2 of aerobics injury, 2 of rock-climbing injury, 2 of fitness training injury and 9 of other sports injuries. We checked the subtypes of acetabular labral tears and the accompanying femoroacetabular impingement. For the cases with accompanying femoroacetabular impingement, we investigated the subtypes according to the types of sports, gender and age. At last follow-up, we checked the Harris Hip Score (HHS), the Hip Outcome Score (HOS) sports scale and the percentage of patients who returned to their sports activity. RESULTS: The average age of symptomatic onset was 26 years (range, 12 to 65 years). The ratio of males to females was 29 : 12. An average duration of the hip pain was 17 months (range, 1 to 60 months). The degenerative type of acetabular labral tears was the most prevalent with 32 cases (78%), and there were 9 cases (22%) of the partial tear type. Thirty cases (73%) were accompanied by femoroacetabular impingement. The average age of the 23 cases (56%) of the cam-type was 23 years (range, 12 to 48 years), and it was more likely to occur in men (87%) and for people practicing martial arts such as Taekwondo or Hapkido. An average age of the 5 cases (12%) of the pincer-type was 26 (range, 16 to 43 years), it usually occurred in women (60%) and for non-martial arts such as golf and gymnastics. There were 2 cases of the mixed type (cam + pincer-type). At 27 months follow-up, the HHS was 61 to 92 points, the HOS sports scale increased 43 to 75%, and the rate of returning to sports was 71%. CONCLUSIONS: In spite of the early expression of symptoms and the short duration of the acetabular labral tears, the high rate of degenerative acetabular labral tears in sports patients is likely associated with repetitive injury after the expression of symptoms. Femoroacetabular impingement in sports patients is seemed to be a cause of the early occurrence of acetabular labral tears. Because the possibility of acetabular labral tears is high in femoroacetabular impingement, sports patients may need to undergo early screening for the diagnosis and care of femoroacetabular impingement.

Apophyseal injuries of the pelvis have increased recently with increased participation of teenagers in contact sports. Apophyseal fractures of the pelvis should be ruled out from apophysitis, os acetabuli and bony tumors. We report a case of fracture of anterior-inferior iliac spine following indirect injury to the hip in a young football player. The patient failed to get better with nonoperative management and continued to have pain in the left hip and signs and symptoms of impingement. He improved following surgical excision of the heterotopic bone and did not have any evidence of recurrence at 2 years follow- up.
