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.
ObjectiveTo evaluate the effectiveness of hemiarthroplasty combined with greater trochanter reattachment device for intertrochanteric fractures in elderly patients. MethodsA retrospective analysis was made on the clinical data of 34 patients (35 hips) with intertrochanteric fractures underwent hemiarthroplasty combined with greater trochanter reattachment device between February 2010 and April 2013.Of 34 patients,16 were males (16 hips) and 18 were females (19 hips),and the mean age was 85.6 years (range,77-95 years).All fractures were caused by falling.The left hip was involved in 20 cases,the right hip in 13 cases,and the bilateral hips in 1 case.There were 33 cases (34 hips) of fresh fracture,and 1 case (1 hip) of old fracture.Fractures were rated as type Ⅲ in 6 cases (6 hips),type IV in 11 cases (11 hips),and type V in 17 cases (18 hips) according to Evans-Jensen standard.All of the patients had different degree of osteoporosis and internal diseases. ResultsAll patients underwent surgery successfully.The operation time was 70-90 minutes (mean,76.6 minutes);the intraoperative blood loss was 260-400 mL (mean,301.5 mL);the postoperative drainage was 80-530 mL (mean,290.6 mL);and the hospitalization time was 10-12 days (mean,11.7 days).Postoperative infection of incision occurred in 1 case,which was cured after dressing;primary healing of incision was obtained in the other patients.No lower extremity deep vein thrombosis or other complications was observed.Twenty-six cases (27 hips) were followed up 12-48 months (mean,21.3 months).X-ray examination showed fracture healing,and the healing time was 2.5-3.5 months (mean,2.8 months).There was no dislocation,prosthesis loosening,dislocation,loosening of titanium cable,periprosthetic osteolysis,or other complications during the follow-up period.According to Harris hip score,the results were excellent in 8 hips,good in 15 hips,fair in 4 hips,and the excellent and good rate was 85.2% at 1 year after operation. ConclusionThe hemiarthroplasty combined with greater trochanter reattachment device is a feasible and effective method to treat intertrochanteric fractures in the elderly patients.It can allow early ambulation and improve quality of life,but it is necessary to strictly control the indications,and perioperative management should be paid attention.
ObjectiveTo compare the clinical efficacy between deep medial collateral ligament (dMCL) repair and conservative treatment for complete MCL rupture. MethodsBetween August 2009 and December 2013, 36 patients with grade 3 MCL rupture underwent superior MCL (sMCL) reconstruction with tibial Inlay technique. Of 36 cases, 19 received dMCL repair (repair group), and 17 received conservative treatment (conservation group) after sMCL reconstruction. There was no significant difference in gender, age, knee sides, type of injury, disease duration and preoperative medial joint opening, knee Lysholm scores, and International Knee Documentation Committee (IKDC) score between 2 groups (P > 0.05). The Lysholm and IKDC scores, medial joint opening, range of motion (ROM), visual analogue scale (VAS) scores, and complications were used to assess the knee joint function. ResultsAll patients achieved primary incision healing without acute postoperative complications of incision infection and deep vein thrombosis in the lower limb. The patients were followed up 28-65 months (mean, 46.3 months) in the repair group, and 26-69 months (mean, 45.9 months) in the conservation group. No knee stiffness, vascular or nerve injury, and knee joint infection occurred in 2 groups. All the patients recovered medial stability at 2 years postoperatively. At 2 years after operation, no significant difference was shown in knee ROM between 2 groups (t=0.26, P=0.80); the VAS score of the repair group was significantly lower than that of the conservation group (t=5.22, P=0.00); medial joint opening, IKDC score, and Lysholm score were significantly improved when compared with preoperative ones in 2 groups (P < 0.05), but no significant difference was found between 2 groups (P>0.05). ConclusionWhether or not additional dMCL repair is performed can recover medial stability after sMCL reconstruction. However, the additional dMCL repair is better in relieving medial knee pain than the conservative treatment.
