ObjectiveTo investigate the short-term effectiveness of arthroscopic assisted double Endobutton “8” buckle fixation in the treatment of Rockwood Ⅲ type acute acromioclavicular joint dislocation.MethodsThe clinical data of 12 patients with Rockwood Ⅲ type acute acromioclavicular joint dislocation who were treated with arthroscopic assisted double Endobutton “8” buckle fixation between June 2016 and June 2019 were analyzed retrospectively. There were 8 males and 4 females, with an average age of 47.0 years (range, 36-58 years). There were 4 cases of left shoulder and 8 cases of right shoulder. The causes of injury included traffic accident injury in 7 cases and falling injury in 5 cases. The average time from injury to operation was 5.0 days (range, 3-14 days). Before operation and at last follow-up, the shoulder joint activity was recorded; the improvements of function and pain were evaluated by Constant score and visual analogue scale (VAS) score, respectively; the reduction was evaluated by measuring the coracoid spacing of the affected side on the anteroposterior X-ray film of shoulder joint.ResultsAll 12 cases were followed up 6-36 months, with an average of 20.6 months. All the incisions healed by first intention. There was no complications such as clavicle and coracoid fractures and Endobuton displacement. At last follow-up, the range of motion of the abduction improved from preoperative (77.5±4.5)° to (162.5±6.5)°, the range of motion of forward flexion improved from (84.1±5.2)° to (169.5±5.8)°, the Constant score improved from 42.5±2.3 to 92.4±2.3, the VAS score improved from 5.4±0.8 to 0.6±0.5, and the coracoid spacing reduced from (20.5±1.4) mm to (9.2±0.6) mm, all showing significant differences (P<0.05).ConclusionArthroscopic assisted double Endobutton “8” buckle fixation for the treatment of Rockwood Ⅲ type acute acromioclavicular joint dislocation is safe, less invasive, and quicker recovery. It can effectively alleviate shoulder pain, significantly improve the mobility of the shoulder joint, and achieve good short-term effectiveness.
Objective To investigate the effects of enhanced recovery after surgery (ERAS) on postoperative function and pain in total hip arthroplasty (THA) patients with high comorbidity. Methods Patients with THA who were admitted between January 2020 and January 2022 were selected as the study objects, and a total of 223 patients with high comorbidity met the selection criteria. Patients were randomly divided into two groups using the random envelope method. During perioperative period, 112 cases in the ERAS group were treated according to the ERAS protocol and 111 cases in the control group with the traditional protocol. There was no significant difference in gender, age, body mass index, Charlson comorbidity index, preoperative diagnosis, the type and number of the comorbidities, preoperative visual analogue scale (VAS) score between the two groups (P>0.05). However, the Harris score of ERAS group was significantly lower than that of control group before operation (P<0.05). Preoperative and postoperative hospital stays were recorded. The VAS score was used to evaluate the pain before operation, at 1 day after operation, at the leaving bed time, at the day after discharge, and at 2 weeks after operation. Harris score was used to evaluate hip function before operation and at 2 weeks, 1 month, 3 months, 6 months, and 12 months after operation. The incidence of complications, 30-day readmission rate, mortality rate, and patient’s satisfaction were recorded. Results The length of preoperative hospital stay in ERAS group was significantly shorter than that in control group (P<0.05). But there was no significant difference in the length of postoperative hospital stay between groups (P>0.05). All patients in the two groups were followed up 12 months. The VAS score in the two groups after operation was lower than that before operation, and showed a gradually trend with the extension of time, with significant differences between different time points (P<0.05). VAS scores of ERAS group were significantly lower than those of control group at different time points after operation (P<0.05). The postoperative Harris scores in both groups were higher than those before operation, and showed a gradually increasing trend with the extension of time, with significant differences between different time points (P<0.05). Harris scores of ERAS group at 2 weeks, 1 month, and 3 months after operation were significantly higher than those of control group (P<0.05). Complications occurred in 2 cases (1.79%) of the ERAS group and 6 cases (5.41%) of the control group, with no significant difference in incidence (P>0.05). In the control group, 1 case was readmitted within 30 days after operation, and 1 case died of severe pneumonia within 1 year of follow-up. There was no readmission or death in ERAS group, and there was no significant difference in the above indexes between the two groups (P>0.05). At last follow-up, the satisfaction rate of patients in ERAS group was slightly higher than that in control group, but the difference was not significant (P>0.05). Conclusion For THA patients with high comorbidity, ERAS protocol can shorten preoperative waiting time, better reduce pain, and improve hip function.
ObjectiveTo investigate the short-term effectiveness of derotational distal femoral osteotomy (DDFO) combined with medial patellofemoral ligament (MPFL) reconstruction in treatment of recurrent patellar dislocation with excessive femoral anteversion angle (FAA≥30°). MethodsBetween June 2017 and August 2019, 17 patients with recurrent patellar dislocation with FAA≥30° were treated with DDFO and MPFL reconstruction. There were 5 males and 12 females, aged 14-22 years, with an average of 17.7 years. The patella dislocated for 2 to 8 times (mean, 3.6 times). The disease duration was 2-7 years (mean, 4.6 years). The patellar apprehension tests were positive. Preoperative pain visual analogue scale (VAS) score, Lysholm score, Tegner score, and Kujala score were 4.2±1.1, 47.8±8.1, 3.6±1.1, and 56.8±5.7, respectively. FAA, mechanical lateral distal femoral angle (mLDFA), lateral patella displacement (LPD), tibial tuberosity-trochlear groove distance (TT-TG) were (34.9±3.4)°, (85.8±3.0)°, (13.7±3.8) mm, and (23.1±2.1) mm, respectively. ResultsAll incisions healed by first intention, and there was no complications such as knee stiffness, infection, and re-dislocation of the patella. All patients were followed up 13-25 months, with an average of 17.7 months. The imaging review showed that 1 case of osteotomy did not union, and achieved satisfactory results after the secondary revision and strengthening fixation; the osteotomies of other patients healed completely after 3 to 4 months of operation. The patellar apprehension tests were negative. At last follow-up, the FAA, mLDFA, LPD, and TT-TG were (15.6±2.7)°, (83.0±2.1)°, (5.0±2.6) mm, and (20.5±2.5) mm, respectively; the VAS score, Lysholm score, Tegner score, and Kujala score were 2.4±1.4, 93.4±7.8, 6.8±1.5, and 89.0±8.0, respectively. There were significant differences in the above indicators between pre- and post-operation (P<0.05). ConclusionDDFO combined with MPFL reconstruction for the recurrent patellar dislocation with excessive FAA (≥30°) can achieve good short-term effectiveness, significantly reduce knee pain, and improve function.
Objective To study the anatomic reconstruction method of posterolateral complex (PLC) in combination injury of posterior cruciate ligament (PCL) and PLC of knee, and explore its early clinical effect. Methods A total of 16 patients (10 males and 6 females) with PCL and PLC injuries admitted to the Affiliated Hospital of Southwest Medical University between January 2017 and January 2019 were retrospectively analyzed. The PCL was reconstructed with artificial ligament under arthroscopy, and autologous semitendinosus and gracilis muscles were used to reconstruct the PLC using the modified Laprade procedure. We measured the tibia posterior displacement on stress radiographs, lateral compartment gapping on varus stress radiographs, external rotation angle of tibia, and range of motion (ROM) of knee before and after operation, observed and recorded the postoperative complications, and evaluated the joint function according to the score of International Knee Documentation Committee (IKDC) and Lysholm Knee score before and after operation. Results All the 16 patients were followed up for 12 to 25 months, with an average of 17 months. The stress radiographs at the last follow-up showed that the tibia posterior displacement [(18.42±4.93) vs. (3.63±2.37) mm], lateral compartment gapping [(13.70±3.19) vs. (3.28±1.89) mm], external tibial rotation at 30° and 90° of flexion [30°: (14.75±2.84) vs. (2.44±2.06)°; 90°: (15.94±2.52) vs. (2.72±2.14)°] were significantly reduced compared with those before surgery. Lysholm score (45.42±10.94 vs. 85.19±7.11) and IKDC grade were obviously improved compared with those before surgery. All the above indicators showed statistically significant differences (P<0.05). The postoperative ROMs of knees of 13 patients returned to normal, and 0-10° flexural function was limited in 3 patients. None of the patients suffered from infection, loose internal fixation, nerve injury, or other complications. Conclusion Modified Laprade PLC reconstruction combined with arthroscopic reconstruction of PCL can effectively restore the posterior and posterolateral rotatory stability of the knee, and is worthy of clinical promotion.
