Reattachment of the articular cartilage component of type 1 subchondral cystic lesions of the medial femoral condyle with polydioxanone pins in 3 horses
Authors: Sparks Holly D. , Nixon Alan J. , Bogenrief David S. 
Published: March 2011

Abstract
Case Description—3 horses were referred for treatment of subchondral cystic lesions of 1 or both medial femoral condyles.
Clinical Findings—All horses had clinically apparent lameness confirmed to be due to a radiographically evident subchondral cystic lesion of the medial femoral condyle with a large articular component (> 15 mm) and shallow subchondral depth (< 10 mm). Arthroscopic assessment of affected cartilage revealed undulating cartilage with a relatively smooth surface and extensive residual perimeter attachment.
Treatment and Outcome—Resorbable polydioxanone pins were used arthroscopically to reattach the cartilage overlying the subchondral cystic lesions. A biologic graft (bone marrow aspirate concentrate or allogeneic chondrocytes) was injected into the depths of the cystic cavity following cartilage reattachment. Follow-up examination confirmed radiographic resolution of the lesion and elimination of clinical signs within the treated femorotibial joint.
Clinical Relevance—Lesions with a large area of affected articular cartilage have been associated with a decreased rate of return to athletic function following arthroscopic debridement, likely secondary to the loss of subchondral architecture and the production of imperfect fibrocartilage repair. Salvage of the affected cartilage in a select population of horses with progressively expanding but shallow subchondral cystic lesions of the medial femoral condyle is possible and may improve radiographic and clinical outcome.

Zonal character of the flora of kurgans in central and southern Ukraine
In the years 2004-2010 floristic studies were carried out on kurgans in 4 different climatic/vegetation zones: 3 steppe zones (west and central Pontic desert steppe, west Pontic grass steppe, west and central Pontic herb-rich grass-steppe) and a forest steppe zone. Among the 450 kurgans surveyed, 106 barrows met the selection criteria. The species composition and the contribution of different life forms to the flora of kurgans changed along the north-south gradient. Jaccard's similarity coefficient and Wards clustering method were used to compare the qualitative composition of flora in particular zones. The results of this comparison confirmed floristic differences between kurgans located in the four zones. Kurgans in the desert steppe zone proved to have the most distinct flora among the floras considered. The biggest similarities were found between the flora of kurgans in the forest steppe zone and that of barrows in the west and central Pontic herb rich grass steppe.

Genetic divergence among Corylus colurna genotypes based on morphological characters of hazelnut
Genetic divergence was studied in 41 genotypes of Corylus colurna on the basis of 15 morphological characters of nuts. The divergence among genotypes was estimated by the Mahalanobis' method and the studied genotypes were grouped into clusters by Tocher's method. The obtained data were analysed using the PCA and CA. As a result, 9 genotype clusters were distinguished and a wide diversity among genotypes originating from the same locality was found. It has been proposed that for obtaining the most desirable transgressive segregates in Corylus colurna, genotypes from the genetically most distant clusters should be crossed.

Lindernia procumbens in Poland: the relationship between weather conditions and the occurrence of the species
New data regarding the occurrence of Lindernia procumbens (prostrate false pimpernel) are discussed and its current geographical range in Poland is given. A comparison of its past and present distribution in Poland indicates an advancement of the distribution limit northwards, which may be caused by climate changes, mostly, by an increased number of heat waves in the warm half-year. The relationship between the occurrence of the species and specific meteorological conditions, especially, unusually hot and dry summer periods, is analysed using long-term meteorological surveys.

Genetic differentiation of common reed (Phragmites australis) populations from selected lakes of Pomerania (NW Poland), revealed by electrophoretically detected peroxidase variability
Three populations of common reed (Phragmites australis (Cav) Trin. ex Steud.), growing under differing edaphic conditions in lakes near the town of Koszalin (the Pomerania region in north-western Poland), were studied in respect to frequencies of electrophoretically detected allozymes in two peroxidase loci: a monomeric locus with three alleles and a dimeric locus with two alleles. On the basis of genetic distances, similarity between these populations and levels of variation were assessed both within populations (GST = 0.0376) and between populations (DST = 0.0194). Gene flow between populations was low (Nm = 6.399).

The impact of former iron ore mining on the transformation of vegetation cover of the Gielniowski Hump (Małopolska Upland)
The impact of the 17th-19th century iron ore mining on the current state of vegetation cover of the Gielniowski Hump, an upland region situated within the Old Polish Industrial Region (a former centre of mining and smelting), was studied. In the course of the research, the detailed floristic lists were compiled using the cartogram method (ATPOL grid) and phytosociological relevés were made according to the Braun-Blanquet method. Relevés were taken both at the post-mining sites (on spoil banks) and, for comparative purposes, in the adjacent, not affected areas. The obtained results show significant differences between the flora and vegetation of the sites affected and unaffected by mining. These differences result from the changed mineralogical composition of soil in the post-mining areas, which has lead to an increase in the proportion of mesophilous forest communities and in the number of species of the class Querco-Fagetea as compared to the unaffected sites. Overall, the former iron ore mining activity has increased the biodiversity level in the Gielniowski Hump mesoregion due to an increase in the total number of species in the area, brought about by the formation of a mining-related habitat mosaic.

Arthrofibrosis of the Knee Following Anterior Cruciate Ligament Reconstruction
Authors: Eckenrode Brian J. , Sennett Brian J. 
Published: March 2011

The patient was a 47-year-old woman who had been referred to a physical therapist following an anterior cruciate ligament reconstruction of the left knee, using a bone-patellar tendon-bone autograft. While temporary within-session knee extension range-of-motion gains were recorded following physical therapist interventions, there was a lack of sustained improvement. Magnetic resonance imaging revealed an intact anterior cruciate ligament graft and a moderate joint effusion, as well as an area of intra-articular arthrofibrosis anterior to the anterior cruciate ligament graft. The patient underwent arthroscopic surgery and, after debridement of the joint arthrofibrosis, was referred to the physical therapist. Following 2 months of treatment, the patient demonstrated full symmetrical knee range of motion, reported no pain, and had initiated a running program without difficulty.

Hip Degenerative Joint Disease in a Patient With Medial Knee Pain
Authors: Poppert Elizabeth , Kulig Kornelia 
Published: March 2011

The patient was a 53-year-old man referred to a physical therapist with a chief complaint of worsening right medial knee pain of 3 months' duration. He had a history of anterior cruciate ligament reconstruction 7 years prior, and recent diagnostic imaging studies had not been performed. Physical examination of the right knee was unremarkable, without reproduction of his chief complaint of medial knee pain. During examination of the right hip, however, combined movements of hip flexion, internal rotation, and adduction, as well as hip distraction and compression, reproduced the patient's knee pain. While radiographs of the right knee were unremarkable, radiographs of the right hip revealed acetabular undercoverage, superolateral joint space narrowing, and subchondral sclerosis. Magnetic resonance imaging of the hip, with and without intra-articular gadolinium, identified developmental dysplasia with marked acetabular undercoverage and moderately advanced degenerative joint disease. The patient did not respond to conservative management and subsequently underwent total hip arthroplasty 9 months after first being seen by the physical therapist, which resulted in complete resolution of his medial knee pain.

Published: March 2011

A 26-year-old man presented to physical therapy for evaluation of right shoulder pain. While history and physical examination findings were most consistent with right shoulder impingement, a firm mass over the acromioclavicular joint was observed. Radiographs of the right shoulder revealed a soft tissue prominence adjacent to the acromioclavicular joint, while contrast-enhanced magnetic resonance imaging revealed a 9 × 16-mm soft tissue mass arising from the right acromioclavicular joint. The patient underwent incisional biopsy, acromioclavicular joint capsulotomy, and distal clavicle excision. Histological evaluation revealed hyalinized fibrovascular connective tissue with focal calcification but no hemosiderin (insoluble iron deposits), consistent with synovial chondromatosis. The patient returned to full activity without limitations postoperatively. J Orthop Sports Phys Ther 2011;41(2):118. doi:10.2519/jospt.2011.0403

Authors: Sole Gisela , Milosavljevic Stephan , Nicholson Helen , Sullivan S. John 
Published: March 2011

Study Design Cross-sectional, controlled laboratory study. Objectives To determine whether thigh muscle isokinetic torque patterns and activity, measured by electromyography (EMG), of individuals with hamstring injury differ from control individuals. Background Neuromuscular control during thigh muscle strength assessment following hamstring injuries has not been reported. Methods Fifteen athletes with prior hamstring injury (hamstring-injured group [HG]) were compared to 15 uninjured athletes (control group [CG]). The injuries were incurred 6 weeks to 12 months prior to participation, and all injured athletes had returned to at least partial training. Participants performed 5 isokinetic concentric extensor, concentric flexor, and eccentric flexor torque tests at 60°/s in the seated position. Peak torque was determined for each contraction type, as well as average torque for each of 4 time-based movement quartiles. EMG root-mean-squares were calculated in these movement quartiles for the biceps femoris and medial hamstrings. Results No significant differences were found for peak torque for all contractions, when comparing HG injured and uninjured sides to CG bilateral averages. The HG injured limb eccentric flexor torque was significantly lower in the fourth quartile (approximately 25° to 5° knee flexion, hamstring lengthened range) compared to the CG bilateral average (P = .025). Eccentric flexor biceps femoris and hamstrings EMG root-mean-squares of the HG injured and the uninjured sides were significantly lower in the second to fourth quartiles (towards the lengthened range), compared to the CG bilateral averages (P<.05). Conclusion Decreased strength and EMG activation in a lengthened hamstrings range for the athletes with prior hamstring injury suggested a change in neuromuscular control. Lengthened range assessment of isokinetic eccentric flexor torque may be useful for the assessment of athletes with a prior injury; however, results should be confirmed with prospective studies.

Published: March 2011

Study Design Case-control study. Objectives To compare the results of 5-position grip strength testing between a group of individuals newly diagnosed with clinical depression and a group of age-matched and sex-matched individuals without depression. Background Clinicians often employ 5-position (or 5-rung) grip strength dynamometry as a measure of sincerity of effort. However, patients with clinical depression are known to show altered performance on motor skill tests. Therefore, the results of 5-position grip strength dynamometry in the clinically depressed may be subject to misinterpretation. Methods Consecutive patients newly diagnosed with clinical depression (n = 45) and age- and sex-matched individuals without clinical depression (n = 45) were recruited over a 3-month period. Each group underwent identical 5-position grip strength testing of both hands. Measures were analyzed using a statistical analysis method based on an 8.5-lb (3.83-kg) SD cutoff and visual analysis of force curve plots by clinicians naïve to the participants' diagnosis. Results Participants with clinical depression had an SD equal to or less than 8.5 lb in 60 of 90 hands tested, while the participants in the control group had an SD equal to or less than 8.5 lb in 1 of 90 hands. Clinicians who analyzed force plots considered participants with depression to have exerted “limited effort” in 70% of cases and those who were not depressed to have exerted limited effort in 18% of cases. Conclusion A high percentage of individuals diagnosed with clinical depression produced statistical and graphical representations of 5-position grip strength measures that suggested poor volitional effort, which is often interpreted as lack of sincerity of effort. Clinicians unaware of the presence of clinical depression in patients could misinterpret the results of 5-position grip strength testing in this population.

Longitudinal Gait and Strength Changes Prior to and Following an Anterior Cruciate Ligament Rupture and Surgical Reconstruction: A Case Report
Authors: Robbins Shawn M.K. , Clark Jessica M. , Maly Monica R. 
Published: March 2011

Study Design Case report. Background Cross-sectional studies have examined deficits following anterior cruciate ligament (ACL) rupture and subsequent reconstructive surgery. Few studies present preinjury data that may assist in identifying risk factors for ACL rupture. This case report compares gait and strength measures obtained prior to ACL rupture, with follow-up assessments of these measures after rupture and reconstructive surgery. Case Description A 23-year-old woman sustained a noncontact rupture of her right ACL. Kinematic and kinetic gait data were collected using 3-dimensional motion analysis and a synchronized force plate. Knee strength was measured using an isokinetic dynamometer. Data for knee active range of motion (AROM) and the Lower Extremity Functional Scale (LEFS) were also collected. The analyses were descriptive and interpreted based on previously published minimal detectable change and minimal clinically important difference values. Outcomes Before her injury, the patient demonstrated a low external knee flexion moment during gait. Kinematic and kinetic gait abnormalities were present following rupture and persisted at 13 months postsurgery. The patient demonstrated knee strength deficits following ACL rupture and surgery. Steady gains in LEFS and knee AROM occurred following rupture and surgery. Discussion Preinjury data may identify risk factors for ACL rupture. Future studies should examine whether a low external knee flexion moment during gait or sport-related activity is a risk factor for ACL rupture. The patient demonstrated deficits in gait and strength that persisted at 13 months postsurgery. Level of Evidence Therapy, level 4.

Authors: Chinkulprasert Chatchada , Vachalathiti Roongtiwa , Powers Christopher M. 
Published: March 2011

Study Design Controlled laboratory study using a repeated-measures design. Objective To quantify patellofemoral joint reaction force (PFJRF) and stress (PFJS) during forward step-up (FSU), lateral step-up (LSU), and forward step-down (FSD) exercises. Background Although FSU, LSU, and FSD exercises are commonly used in patellofemoral joint rehabilitation programs, the influence of these stepping tasks on patellofemoral joint kinetics has not been quantified. Methods Three-dimensional lower extremity kinematics and kinetics and electromyographic (EMG) data were obtained from 20 healthy adults during their performance of FSU, LSU, and FSD exercises. The step height for each participant was adjusted to permit a standardized knee flexion angle of 45°. A previously described biomechanical model of the patellofemoral joint was used to quantify PFJRF and PFJS during each task. Peak PFJRF and PFJS during the concentric and eccentric phases of each step task were compared using a 2-factor analysis of variance (ANOVA). Results When collapsed across concentric and eccentric phases, peak PFJS was significantly greater during the FSD (mean ± SD, 13.8 ± 0.4 MPa) compared to the LSU (11.5 ± 0.8 MPa; P<.001) and FSU (11.2 ± 0.6 MPa; P = .002) exercises. Peak PFJRF also was significantly greater during the FSD (51.1 ± 2.7 N/kg) compared to the LSU (44.1 ± 3.4 N/kg; P<.001) and FSU (43.6 ± 2.3 N/kg; P = .023) exercises. Conclusion In selecting exercises that promote lower extremity muscle strengthening while minimizing patellofemoral joint loading, LSU and FSU should be considered over FSD exercises, if the same step height is used.

Design and Construction of a Novel Low-Cost Device to Provide Feedback on Manually Applied Forces
Authors: Tuttle Neil , Jacuinde Guillermo 
Published: March 2011

Study Design Design and evaluation, technical note. Objectives To describe the design of a simple, low-cost device for providing feedback of manually applied forces to the cervical spine, and to assess the device against specific design criteria. Background The forces applied during manual therapy may vary by as much as 500% between practitioners. But consistency can be improved in students when they are provided with contemporaneous feedback. The current methods of providing feedback, however, are expensive, complex, and/or preclude their performance in a clinically relevant manner. Methods The design of the device was assessed in accordance of the following criteria: (1) ease of use, (2) low cost, (3) minimal interference with technique, (4) ability to provide feedback with suitable accuracy at forces up to 50 N, and (5) no requirement of specialized skills to construct. Results A device is described that interfaces with standard computers through the sound card and measures force, using thin, low-cost, force-sensing resistors. Evaluated against the design criteria, the device (1) is easy to set-up and use, (2) can be produced for under $30 US dollars, (3) creates minimal interference with performance of a variety of techniques, (4) has limits of agreement from −3.8 to 4.2 N for forces of 5 to 45 N and repeatability coefficients of ±2.0 N or 12%, and (5) can be constructed without specialized skills or knowledge. Conclusion A device is described that fulfils most of the design criteria for providing feedback on forces for physical therapy students and may have applications in other fields.
