SummaryTwo Domestic Shorthaired cats were admitted after sustaining a traumatic lateral elbow luxation. Non-surgical management with reduction and external coaptation was unsuccessful at maintaining reduction. At surgery, the lateral collateral ligament (LCL) was intact but grossly elongated in one case, and ruptured in the other. Trans-condylar, trans-radial and trans-ulnar tunnels were drilled from lateral to medial and a suture prosthesis was used in order to augment a suture imbrication of the LCL in the fist cat. The prosthesis was used as a stand-alone procedure in the second case. No postoperative complications occurred and both patients regained excellent elbow range of motion without any observable lameness.

AbstractThe aim of this study was to report the outcome in a 6-year-old male English Setter dog that suffered a combination of divergent elbow dislocation and open distal ulnar fracture. This study is a case report. After surgical reduction in the elbow luxation, the dog was treated with the TightRope fixation system used as replacement of the lateral collateral ligament, a radioulnar positional screw, and external skeletal fixation. Removal of all implants was performed 3 months postoperatively. The 6-month follow-up visit found the dog without lameness, displaying normal activity, and with normal elbow range of motion and normal Campbell's test. Successful surgical management was achieved with good long-term results using TightRope, a positional screw, and an external skeletal fixator.

The Mean

Medial Patellofemoral ligament(MPFL) is the main passive stabilizer of the patellofemoral joint. MPFL is injured in the 2/3 rds of the patients after patella luxation. In this study we present a novel aproach to the anatomical MPFL reconstruction and preliminary results of the technique. We operated 7 patients(4 female and female and 3 male) who applied to our clinic after a patella luxation episode. The mean age was 27,1 years(16-42). The mean follow up time was 23,5 months(24-35). We evaluated the patients clinically and radiologically for concommitant pathologies. 1 patient had patellar cartilage demage and patella alta, 1 patient had medial collateral ligament rupture, 1 patient had lateral collateral ligament and anterior cruciate ligament rupture and these pathologies were treated as well. The operation was done in the supine position on a radiolucent table and under the image intensifier control. The semitendinosus autograft was prepared. The femoral tunnel was drilled and double strand graft was introduced in the femoral tunnel and secured with ToggleLoc femoral fixation device(Biomet). The graft was advanced over the facia to the patellar side and passed through the 2 patellar tunnels and tied to each other. After exercising the knee the graft tension was rechecked at 30 degrees of knee flexion. Early postoperatively range of motion and quadriceps strenghtening exercises were carried out and patients were allowed to bear weight. All of the patients had full range of motion and free of pain. Postoperative x-ray and MRI examinations revealed the correction of patellar tilt and lateral shift of the patella in all patients. The only complication was a fissure of patella in 1 patient in the 6th week of rehabilitation due to anteriorly located patellar tunnel and heavy exercise. We immobilsed the patient in a brace and the patient returned to rehabilitation after 6 weeks when the fissure healed. All the patients returned to the previous functional level. Our anatomical MPFL technique uses ToggleLoc for the femoral side but implant free at the patellar side. The technique provided excellent preliminiary result in all of the patients. The technique allows graft retensioning again and again from both the femoral and the patellar side. The double bundle reconstruction seems to immitate the natural behaviour of the MPFL. However patellar tunnels carry a substantial risk of patella fracture and must be placed with great attention.

Subjective Outcomes

Background: While early weightbearing protocols have been advocated after anterior cruciate ligament (ACL) reconstruction, early weightbearing after fibular (lateral) collateral ligament reconstruction has not been well defined. Purpose: (1) To determine if early partial controlled weightbearing after fibular collateral ligament (FCL) reconstruction resulted in an objective difference in laxity on varus stress radiographs at postoperative 6 months as compared with nonweightbearing, and (2) to determine if there was a difference in pain, edema, range of motion, and subjective patient-reported outcomes between these groups at 3 time points. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Patients were prospectively enrolled from January 2014 to April 2017. Patients who underwent isolated FCL reconstruction or combined ACL and FCL reconstructions were included in this study. Patients were randomly assigned to either a control group (nonweightbearing for 6 weeks) or a treatment group (partial controlled weightbearing at 40% body weight with crutches for 6 weeks). Patient-related data, including knee pain, edema, and range of motion, were collected for all patients at postoperative day 1, 6 weeks, and 6 months. Subjective outcomes were collected preoperatively and at 6 months postoperatively. The primary objective endpoint was varus stability, evaluated by bilateral varus stress radiographs obtained preoperatively and at 6 months postoperatively. Results: Thirty-nine patients were enrolled in the study, with 6-month follow-up obtained for 36 (92%). There was a significant improvement between the preoperative side-to-side difference (SSD) (2.4 ± 1.0) and postoperative SSD (0.2 ± 1.0) for lateral compartment laxity on varus stress radiographs among all patients ( P < .001). Clinical and statistical equivalence was found between groups in terms of SSD on varus stress radiographs ( P < .001). The SSD in knee edema was significantly lower in the partial early weightbearing group (beta = −0.6 cm, P = .001), but there were no significant group differences in knee pain, flexion, or extension. All patients demonstrated significant improvements in subjective outcome scores between the preoperative and 6-month postoperative conditions ( P < .001 for every score measured). Conclusion: Clinical and statistical equivalence was found at postoperative 6 months between the early partial weightbearing and nonweightbearing groups among patients undergoing either an isolated FCL reconstruction or a combined ACL and FCL reconstruction. There were no significant differences observed between the groups regarding knee stability, pain, swelling, range of motion, or subjective outcomes. Given these findings, the authors recommend early partial weightbearing after isolated FCL reconstruction or combined ACL and FCL reconstruction.

Abstract CASE DESCRIPTION A 3-year-old 5-kg sexually intact female silvery langur housed in a single-species group at a zoological institution was presented because of acute trauma to the left forelimb. CLINICAL FINDINGS Radiography of the left forelimb revealed a type II Monteggia fracture (proximal ulnar fracture with cranial displacement and caudal luxation of the radial head). During surgery, disruption of the annular ligament and rupture of the lateral collateral ligament were noted. TREATMENT AND OUTCOME The langur underwent open reduction and internal fixation of the ulnar fracture and placement of a radioulnar positional screw, a prosthetic lateral collateral ligament, and a temporary hinged type 1A external skeletal fixator. The langur was returned to group housing, underwent behavioral training, and was periodically anesthetized for physical therapy sessions to improve range of motion of the left elbow joint. The external skeletal fixator was removed 4 weeks after surgery, and the radioulnar positional screw was removed 6 weeks after surgery. Three months after surgery, the range of motion of the langur’s left elbow joint was considered normal, and the animal returned to normal activity. CLINICAL RELEVANCE For the captive silvery langur of the present report, surgical stabilization and postoperative management of a type II Monteggia fracture of the left forelimb were successful with recovery of elbow joint function. These techniques may be applied to other captive nonhuman primates, including those that brachiate or are members of social species that must be housed with conspecifics in the postoperative period to maintain group dynamics.

Abstract Purpose The lateral elbow musculature conveys a dynamic valgus moment to the elbow, increasing joint stability. Muscular or tendinous lesions to the anterior half of the common extensor origin (CEO) may provoke a deficiency in the elbow dynamic stabilizers, regardless of their traumatic, degenerative, or iatrogenic aetiology. Furthermore, a role for the radial band of the lateral collateral ligament (R-LCL) has been postulated in the aetiology of lateral elbow pain. This study aimed to evaluate the effects of sequential lateral releases with dynamic ultrasound, evaluating its capability to detect lesions of the CEO and of the R-LCL. Methods Ultrasound investigation of the lateral compartment of the elbow was performed on nine cadaveric specimens with a 10 MHz linear probe in basal conditions, after the release of the anterior half of the CEO and after complete R-LCL release. The lateral joint line widening (λ) was the primary outcome parameter, measured as the linear distance between the humeral and radial articular surfaces. Results The release of the anterior half of the CEO significantly increased λ by 200% compared to the starting position (p = 0.0008) and the previously loaded position (p = 0.0015). Conversely, further release of the R-LCL caused only a marginal, non-significant increase in λ. Conclusions Ultrasound evaluation can detect changes related to tendon tears or muscular avulsions of the CEO and can depict lateral elbow compartmental patholaxity by assessing articular space widening while scanning under dynamic stress. However, it cannot reliably define if the R-LCL is injured. Iatrogenic damage to the CEO should be carefully avoided, since it causes a massive increase in compartmental laxity.

Multiligament Injury

Knee dislocation with concomitant multiligament injury is a rare and devastating injury. We report the successful repair of a rare case of open knee dislocation with concomitant multiligament injury and patellar tendon rupture of an 18-year-old male due to a motorcycle accident. The patient presented with an open wound running parallel to the knee joint line and patellar tendon rupture with full exposure of the cartilage of the distal femur. Staged surgical management including the application of a ring-type external fixator with a hinged joint, lateral collateral ligament repair, medial collateral ligament reconstruction using autogenous hamstring tendon, and joint release was performed. Range of movement was recovered to 0 degrees of knee extension and 80 degrees of knee flexion, and extension lag was negative. The Lysholm score of the patient was recovered to 92. The patient was able to return to work in the construction field 2 years after sustaining the injury. The patient had no complaint of pain and was able to resume construction work, even though reconstruction of the anterior cruciate ligament and posterior cruciate ligament was not performed. The application of a hinged ring-type external fixation device might play a key role in early range of movement restoration and to maintain the reduced position and acceptable recovery of the posterior cruciate ligament injury without the need for reconstructive surgery. This report is the first to describe the safety and effectiveness of staged surgical management for the repair of open knee dislocation with concomitant multiligament injury and patellar tendon rupture. However, further studies with longer follow-up periods will be needed to observe the development of osteoarthritis or weakness of the knee. Staged surgical management is a safe and effective procedure for repairing an open knee dislocation with concomitant multiligament injury and patellar tendon rupture.
