  • RECONSTRUCTION OF THE KNEE STABILITY AFTER RESECTION OF TUMORS OF THE PROXIMAL FIBULA

    Objective To investigate the method and the cl inical outcomes of reconstruction of the knee stability after resection of tumors of the proximal fibula. Methods The cl inical data were retrospectively analyzed, from 16 patients with tumors of the proximal fibula undergoing proximal fibular resections and reconstructions of the lateral collateral ligament and the tendon of the biceps femoris with anchors between January 2008 and December 2009 (test group). Five patients underwent proximal fibular resection but were not given reconstruction surgery at the same period as the control group. There was no significant difference in gender, ages, disease duration, and tumor site between 2 groups (P gt; 0.05). Lateral stress test was performed after operation; X-ray films were taken to measure the joint space. Musculoskeletal Tumor Society (MSTS) functional score system was used to evaluate the joint function. Results All incisions healed by first intention in 2 groups. Iatrogenic complete peroneal nerve function loss occurred in patients undergoing Malawer type II surgical resection. The patients in both groups were followed up 12 to 36 months, with an average of 30 months. One patient with osteosarcoma of the test group developed local recurrence, and died of lung and systemic metastases after 12 months; the other patients had no recurrence. At last follow-up, the results of knee lateral stress test were negative in the test group, and the joint space increased and was classified as grade A; the results of knee lateral stress test were positive in the control group, and the joint space was classified as grade D. The MSTS score was 97.5 ± 3.5 in the test group and 87.5 ± 3.5 in the control group, showing significant difference (t=2.85, P=0.01). Conclusion The reconstruction of the bony attachment of the lateral collateral ligament and the tendon of the biceps femoris with anchors after resection of the proximal fibula is a safe, rel iable, and simple technique to reconstruct knee stabil ity after resection of tumors of the proximal fibula.

  • EXPERIMENTAL RESEARCH OF THE INFLUENCE ON WRIST STABILITY FOLLOWING ULNAR HEAD RESECTION

    The influence on the wrist stability following ulnar head resection (Darrach s procedure)was studied. A series of X-ray films and arthrography of the wrist joint were taken before and after ulnar head re- section. The results showed that after ulnar head resection the radial deviation increased 3 degree(Plt;0.01). and the ulnar deviation 11.92 degree (Plt;0.001). The position of the lunate remained unchanged. Arthrography of the wrist joint demonstrated that 11 specimens had injury of the triangular fibrocartilage.The stability of the wrist joint would no doubt be certainly affected following the ulnar head resction.

  • TREATMENT OF SEVERE MEDIAL COLLATERAL LIGAMENT RUPTURE IN MULTI-LIGAMENT INJURY

    ObjectiveTo compare the clinical efficacy between medial collateral ligament (MCL) repair and MCL reconstruction in multi-ligament injury. MethodsThirty-one patients with MCL rupture and multi-ligament injury of knee joint were treated between August 2008 and August 2012, and the clinical data were retrospectively analyzed. Of 31 patients, 11 cases underwent MCL repair (repair group), and 20 cases underwent MCL reconstruction (reconstruction group). There was no significant difference in gender, age, body mass, injury side, injury cause, and preoperative knee Lyshlom score, International Knee Documentation Committee (IKDC) subjective score, range of motion, and medial joint opening between 2 groups (P > 0.05). The postoperative knee subjective function and stability were compared between 2 groups. ResultsAll incisions healed by first intention, and no postoperative complication occurred. All patients were followed up 2-4 years (mean, 3.2 years). At 2 years after operation, the IKDC subjective score, Lyshlom score, and range of motion were significantly increased in 2 groups when compared with preoperative ones (P < 0.05). The range of motion of reconstruction group was significantly better than that of repair group (P < 0.05). No significant difference was found in IKDC subjective score and Lyshlom score between 2 groups (P > 0.05). The medial joint opening was significantly improved in 2 groups at 2 years after operation when compared with preoperative one (P < 0.05), but no significant difference was found between 2 groups (P > 0.05). ConclusionBoth the MCL reconstruction and MCL repair can restore medial stability in multi-ligament injury, but MCL reconstruction is better than MCL repair in range of motion.

  • A Comparison between Knee Joint Stability Training and Diclofenac in the Treatment of Osteoarthritis of the Knee

    ObjectiveTo evaluate the efficacy and safety of knee joint stability training in treating patients with knee osteoarthritis. MethodsSixty-one patients with knee osteoarthritis treated between April 2014 and April 2015 were randomly divided into 2 groups:rehabilitation group (n=30) and control group (n=31).Patients in the rehabilitation group received knee joint stability training (30-40 minutes once, once every day); the control group received diclofenac sodium orally at 75 mg/d (25 mg per time, 3 times every day).The Western Ontario and McMaster Universities Arthritis index (WOMAC) and short-form health survey (SF-36) were used before and after treatment.Patients' and physicians' assessment of the total efficacy rate was also analyzed. ResultsAfter 5 weeks of treatment, the total efficacy rate assessed by the patients for the rehabilitation group and the control group was respectively 93.33% and 87.10%, and those two numbers assessed by physicians were respectively 86.67% and 80.65%;the differences were not statistically significant (P > 0.05).Significant improvement was observed in the results of WOMAC and SF-36 in both two groups (P < 0.05).There was no significant difference in the clinical efficacy between the two groups (P > 0.05).No incidence of related adverse events occurred in the rehabilitation group, while the incidence of adverse events was 16.13% in the control group (P < 0.05). ConclusionThe knee joint stability training is as effective as diclofenac sodium in treating patients with knee osteoarthritis, but the joint stability training is better tolerated than the latter.

  • Research progress of larger flexion gap than extension gap in total knee arthroplasty

    Objective To summarize the progress of larger flexion gap than extension gap in total knee arthro-plasty (TKA). Methods The domestic and foreign related literature about larger flexion gap than extension gap in TKA, and its impact factors, biomechanical and kinematic features, and clinical results were summarized. Results During TKA, to adjust the relations of flexion gap and extension gap is one of the key factors of successful operation. The biomechanical, kinematic, and clinical researches show that properly larger flexion gap than extension gap can improve both the postoperative knee range of motion and the satisfaction of patients, but does not affect the stability of the knee joint. However, there are also contrary findings. So adjustment of flexion gap and extension gap during TKA is still in dispute. Conclusion Larger flexion gap than extension gap in TKA is a new joint space theory, and long-term clinical efficacy, operation skills, and related complications still need further study.

  • Effectiveness comparison of partial versus intact posterior cruciate ligament-retaining in total knee arthroplasty with cruciate-retaining prosthesis

    ObjectiveTo compare the effectiveness of partial versus intact posterior cruciate ligament (PCL)-retaining in total knee arthroplasty (TKA) with cruciate-retaining (CR) prosthesis.MethodsA total of 200 patients with osteoarthritis, who met the selection criteria and proposed unilateral TKA with CR prosthesis, were included in the study and randomly assigned into two groups (n=100). The patients were treated with intact retention of the double bundles of PCL in intact group and with partial resection of the anterior lateral bundle of PCL and the anterior bone island at the time of intraoperative tibial osteotomy in partial group. Patients with lost follow-up and re-fracture were excluded, and 84 cases in partial group and 88 cases in intact group were included in the final study. There was no significant difference between the two groups (P>0.05) in terms of gender, age, body mass index, course and grade of osteoarthritis, preoperative varus deformity of knee joint, flexion contracture, range of motion, clinical and functional scores of Knee Society Score (KSS). The operation time, wound drainage volume during 24 hours after operation, visual analogue scale (VAS) score at 24 hours after operation, range of motion of knee joint, clinical and functional scores of KSS, and the anteroposterior displacement of knee joint at 30° and 90° flexion positions were compared between the two groups.ResultsThere was no significant difference between the two groups in operation time, wound drainage volume during 24 hours after operation, and VAS score at 24 hours after operation (P>0.05). Patients in both groups were followed up after operation. The follow-up time was 25-40 months (mean, 30.2 months) in intact group and 24-40 months (mean, 31.8 months) in partial group. There was no significant difference in the range of motion and clinical scores of KSS between the two groups at 6, 12, and 24 months after operation (P>0.05). The functional scores of KSS were significantly higher in intact group than in partial group (P<0.05). There was no significant difference between the two groups in the anteroposterior displacement of knee joints at 30° flexion position at 6, 12, and 24 months after operation (P>0.05). When the knee was at 90° flexion position, there was no significant difference between the two groups at 6 and 12 months after operation (P>0.05), but the intact group was significantly smaller than partial group at 24 months after operation (P<0.05). Postoperative incision continued exudation in 4 patients (2 cases of partial group and 2 cases of intact group), and incision debridement in 2 patients (1 case of partial group and 1 case of intact group). No prosthesis loosening, excessive wear, or dislocation of gasket was found during follow-up.ConclusionThe double bundle of PCL plays an equally important role in maintaining the stability of the knee joint, and the integrity of PCL should be kept as much as possible when TKA is performed with CR prosthesis.

  • A study of the correlation between glenohumeral joint congruence and stability in recurrent shoulder dislocations

    ObjectiveTo investigate the correlation between glenohumeral joint congruence and stability in recurrent shoulder dislocations. Methods Eighty-nine patients (89 sides) with recurrent shoulder dislocation admitted between June 2022 and June 2023 and met the selection criteria were included as study subjects. There were 36 males and 53 females with an average age of 44 years (range, 20-79 years). There were 40 cases of left shoulder and 49 cases of right shoulder. The shoulder joints dislocated 2-6 times, with an average of 3 times. The three-dimensional models of the humeral head and scapular glenoid were reconstructed using Mimics 20.0 software based on CT scanning images. The glenoid track (GT), inclusion index, chimerism index, fit index, and Hill-Sachs interval (HSI) were measured, and the degree of on/off track was judged (K value, the difference between HSI and GT). Multiple linear regression was used to analyze the correlation between the degree of on/off track (K value) and inclusion index, chimerism index, and fit index. ResultsMultiple linear regression analysis showed that the K value had no correlation with the inclusion index (P>0.05), and was positively correlated with the chimerism index and the fit index (P<0.05). Regression equation was K=–24.898+35.982×inclusion index+8.280×fit index, R2=0.084. ConclusionHumeral head and scapular glenoid bony area and curvature are associated with shoulder joint stability in recurrent shoulder dislocations. Increased humeral head bony area, decreased scapular glenoid bony area, increased humeral head curvature, and decreased scapular glenoid curvature are risk factors for glenohumeral joint stability.
