Primary ACL Repair and Reconstruction in Isolated ACL Ruptures: Forgotten Joint Scores and the Association Between Residual Laxity and Joint Awareness.

BACKGROUND: Primary anterior cruciate ligament (ACL) repair has recently reemerged as a treatment option for carefully selected proximal ACL tears. However, evidence regarding patient-reported joint awareness and the relationship between postoperative laxity and joint awareness remains limited. PURPOSE: To compare joint awareness, clinical outcomes, and postoperative laxity between primary ACL repair and hamstring tendon autograft reconstruction in carefully selected patients with isolated ACL rupture, and to explore the association between residual laxity and postoperative joint awareness. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: This retrospective cohort study included 85 patients with isolated ACL rupture treated with either primary ACL repair (n = 26) or hamstring autograft reconstruction (n = 59), with a minimum follow-up of 24 months. Clinical outcomes, including visual analog scale score, Lysholm score, International Knee Documentation Committee (IKDC) score, Tegner activity scale score, postoperative knee laxity, return to sport, and rerupture rates, were evaluated. The authors also used the Forgotten Joint Score-12 (FJS-12), a measure of joint awareness, to evaluate patients. A higher score reflects lower joint awareness, suggesting function more similar to a native knee. Multivariable regression analyses were performed to evaluate variables associated with postoperative FJS-12 values. RESULTS: No differences were observed between groups in postoperative Lysholm, IKDC, and Tegner activity scale scores; Lachman- and pivot-shift-assessed postoperative laxity; and return-to-sport rates. However, postoperative FJS-12 values were significantly higher in the repair group compared with the reconstruction group (87.0 &#xb1; 15.0 vs 77.5 &#xb1; 14.2; mean difference, 9.5 points [95% CI, 2.8-16.3]; P = .006), corresponding to a moderate effect size (Cohen d = 0.66). Secondary exploratory regression analyses demonstrated that residual postoperative laxity was associated with lower postoperative FJS-12 values in both Lachman- and pivot-shift-based models (R2 = 0.649 and 0.680, respectively; P < .001 for both). CONCLUSION: In carefully selected patients with proximal ACL tears and adequate tissue quality, no significant between-group differences were detected in conventional clinical outcomes, postoperative laxity, return-to-sport rates, or rerupture rates between primary ACL repair and reconstruction. Primary ACL repair was associated with higher postoperative FJS-12 values at short- to midterm follow-up, suggesting function more similar to that of a native knee. Residual postoperative laxity was associated with lower FJS-12 values in secondary exploratory analyses.

An analysis of maximum mandibular movements, craniofacial relationships and temporomandibular joint awareness in children.

This paper evaluates the relationship between maximum mandibular vertical opening and the following variables: chronological age, craniomandibular relationships, and temporomandibular joint awareness in children. The range of mandibular movement was evaluated in 189 children between the ages of 4 and 14 years, using the method of Agerberg. Measurements were found to be accurate and reliable only in the vertical plane. Cephalometric tracings were made on 131 of the subjects. Significant relationships were noted for maximum vertical opening with age, anterior facial height, and mandibular length. A temporomandibular joint awareness questionnaire was verbally given to all subjects with no parental input. Responses to the questionnaire were found to be unreliable, based upon a retest of 25 subjects one month later. It is noteworthy that all of the changes in responses on the retest were to the same question, "Does your jaw ever feel tired?"

Joint position awareness and sports activity after capsulolabral reconstruction in the overhead athlete.

A total of 24 overhead athletes with posttraumatic, chronic anterior shoulder instability underwent surgery. Twenty-two patients were examined after an average follow-up of 2.8 +/- 0.7 years. On average, a Constant-Score and Constant-Murley-Score of 93.7 +/- 5.3 points and an ASES-Score of 95.0 +/- 5.1 points were achieved. The redislocation rate was 9 %. The study demonstrated, that despite the good clinical results, only 12 out of 22 (55 %) of patients were able to return to their previous sports activity level. This relevant problem is in agreement with other similar studies [ ], so it was further addressed by determination of joint position awareness (JPA) and electromyographic muscle activity. Postoperatively, a persisting deficit of JPA, as well as an altered EMG pattern, was found with a significant reduction in activity of the deltoideus muscle on the operated side. The analysis of the data of each patient showed that there was a significant relation between the restitution of JPA and ability to return to the previous sports activity level. In contrast, the relation between EMG pattern and full recovery to completely unrestricted shoulder function was not significant. The anterior capsulolabral reconstruction enables a reliable restoration of shoulder stability and a low rate of complications. The problem that a relatively high percentage of overhead athletes can not return to their previous performance level is based on an impaired joint position awareness.

Tuberculosis of sacroiliac joint: an unusual presentation.

A 25-year-old man presented with low back pain and fever. After an initial delay, a diagnosis of tuberculosis of left sacroiliac joint was established by fine-needle aspiration of the joint. Awareness of extrapulmonary manifestations of tuberculosis and high index of suspicion will facilitate early diagnosis and treatment.

Irreducible tarsometatarsal fracture-dislocation.

Three mechanisms may prevent closed manipulative reduction of the tarsometatarsal fracture-dislocation: anterior tibialis tendon interposition, incongruity of the medial cuneiform-first metatarsal articulation, and interposition of a fracture fragment in the second metatarsal-intermediate cuneiform joint. Awareness of these mechanisms will assist in the surgical approach to athe irreducible tarsometatarsal fracture dislocation. Such an irreducible fracture-dislocation in a 25-year-old male was successfully reduced openly: anatomic reduction and normal passive range of ankle motion resulted. The patient had a slightly painful midfoot during walker ambulation 10 weeks postinjury.

Lead poisoning from a gunshot wound. Report of a case and review of the literature.

A man was hospitalized on three occasions for symptoms of lead intoxication 20 to 25 years after a gunshot wound that resulted in retention of a lead bullet in his hip joint. The potential for lead toxicity as a complication of a lead missile injury appears to be related to (1) the surface area of lead exposed for dissolution, (2) the location of the lead projectile, and (3) the length of time during which body tissues are exposed to absorbable lead. Cases of lead poisoning of immediate onset resulting from lead shot have been reported in Europe, but all documented cases of ammunition-related plumbism reported in the United States have involved synovial fluid dissolution of a single lead bullet over many years. The solvent characteristics of synovial fluid and associated local arthritis are apparently important factors in the dissolution and absorption of lead from projectiles located in joints. Awareness that lead intoxication can be a complication of retained lead projectiles should allow rapid institution of appropriate diagnostic and therapeutic modalities when such a clinical situation arises.

Awareness of knee joint angle under static conditions.

The ability of subjects to match the angle of a passively positioned knee joint by active positioning of the opposite leg is nearly constant with time from 15s to 3 min. However, their ability to match this angle from memory is equally good. Thus, knowledge of joint angle after movement has ceased does not necessarily require ongoing input from tonic peripheral receptors.

Prevalence of different temporomandibular joint sounds, with emphasis on disc-displacement, in patients with temporomandibular disorders and controls.

Temporomandibular joint (TMJ) sounds are very common among patients with temporomandibular disorders (TMD), but also in non-patient populations. A variety of different causes to TMJ-sounds have been suggested e.g. arthrotic changes in the TMJs, anatomical variations, muscular incoordination and disc displacement. In the present investigation, the prevalence and type of different joint sounds were registered in 125 consecutive patients with suspected TMD and in 125 matched controls. Some kind of joint sound was recorded in 56% of the TMD patients and in 36% of the controls. The awareness of joint sounds was higher among TMD patients as compared to controls (88% and 60% respectively). The most common sound recorded in both groups was reciprocal clickings indicative of a disc displacement, while not one single case fulfilling the criteria for clicking due to a muscular incoordination was found. In the TMD group women with disc displacement reported sleeping on the stomach significantly more often than women without disc displacement did. An increased general joint laxity was found in 39% of the TMD patients with disc displacement, while this was found in only 9% of the patients with disc displacement in the control group. To conclude, disc displacement is probably the most common cause to TMJ sounds, while the existence of TMJ sounds due to a muscular incoordination can be questioned. Furthermore, sleeping on the stomach might be associated with disc displacement, while general joint laxity is probably not a causative factor, but a seeking care factor in patients with disc displacement.

Proprioception and stability: foot position awareness as a function of age and footwear.

We examined the hypothesis that awareness of foot position in terms of the slope of the weight-bearing surface declines with age. We further postulated that the decline would be due to a change in plantar tactile sensibility, and that footwear would further impair position judgments. We compared 15 men aged over 65 years (mean age 73) with 36 men aged under 40 (mean age 30) in terms of estimates of amplitude and direction of surface slopes. We employed a ratio scale of 0-10 representing actual slopes of 0 degrees-25 degrees in increments of 2.5 degrees. In order to examine whether subjects overestimated high angles they were told that the scale ranged from 0 to 15. We found significant differences between the two groups in terms of estimates and the effect of footwear. Psychophysical functions for estimate of slope were 0.95 for the young when barefoot and 0.71 when shod compared with 0.80 and 0.81 respectively for the older men. We conclude that sensitivity to foot position declines with age, mainly owing to loss of plantar tactile sensitivity. Footwear impairs foot position awareness in both young and old. Loss of foot position awareness may contribute to the frequency of falls in later life.

Factors associated with ankle injuries. Preventive measures.

A sense of foot position in humans is precise when barefoot, but is distorted by athletic footwear, which accounts for the high frequency of ankle sprains in shod athletes. It is unclear whether taping and rigid and semi-rigid devices protect against ankle sprains, as all of the studies suggesting this are flawed by inadequate controls. If these devices do protect the ankle, it is not through added support but rather through a partial correction of the deceased foot position awareness caused by footwear. Since taping and rigid and semi-rigid devices interfere with normal movement, there is concern that these might actually increase the frequency of injury at the ankle and/or at different locations. In this respect, taping is less of a concern because it interferes least with normal movement. The best solution for reducing ankle sprains in shod athletes is the use of more advanced footwear to retain maximal tactile sensitivity, thereby maintaining an awareness of foot position comparable to that of the barefoot state or perhaps even improving on it.

Proprioception of the ankle and knee.

Proprioception and accompanying neuromuscular feedback mechanisms provide an important component for the establishment and maintenance of functional joint stability. Neuromuscular control and joint stabilisation is mediated primarily by the central nervous system. Multisite sensory input, originating from the somatosensory, visual and vestibular systems, is received and processed by the brain and spinal cord. The culmination of gathered and processed information results in conscious awareness of joint position and motion, unconscious joint stabilisation through protective spinal-mediated reflexes and the maintenance of posture and balance. Clinical research aimed at determining the effects of articular musculoskeletal injury, surgery and rehabilitation, on joint proprioception, neuromuscular control and balance has focused on the knee and ankle joints. Such studies have demonstrated alterations in proprioception subsequent to capsulo-ligamentous injury, partial restoration of proprioceptive acuity following ligamentous reconstruction, and have suggested beneficial proprioceptive changes resulting from comprehensive rehabilitation programmes.

Investing in emergent literacy intervention: a key role for speech-language pathologists.

Emergent literacy is a developmental period that is receiving renewed and increased emphasis in the fields of education and speech-language pathology because of its influence on the later literacy development and achievement of students. With their strong background in language, language development, and language disorders, speech-language pathologists (SLPs) can make significant contributions to the acquisition of emergent literacy skills. This article focuses on SLP direct-service roles for students with identified communication impairments and on indirect roles of assisting teachers and others to promote the emergent literacy skills of all students. In addition to the acknowledged importance of general oral language, guidelines, suggestions, and resources are offered to foster emergent literacy skills in five specific areas: (1) early phonological awareness, (2) joint book reading and sense of story, (3) alphabetic letter knowledge, (4) adult modeling of literacy activities, and (5) experience with writing materials.

Digital vasculitis associated with joint sepsis in rheumatoid arthritis.

Digital vasculitis complicating RA is not infrequent and is usually benign but may herald the onset of systemic vasculitis. A case is reported of a man with longstanding seropositive RA who developed digital vasculitis in association with septicaemia and multiple joint sepsis. Awareness that the onset of digital vasculitis in RA may be related to infection is important. This is especially so since aggressive immunosuppressive therapy is often used in patients with systemic vasculitis.

Self/other organization in human psychological development.

Evidence from the evolution of human cultural behavior and learning, embryology and genetics of the brain, and the behavior of human infants indicates that the critical and uniquely human motives for cooperative imagination and joint interest in objects and tasks are determined by expression of genes and epigenetic neural systems elaboration long before birth, along with essential peripheral organs of perception and motor expression that will serve in communication by rhythmic facial, vocal, gestural, and body movement signals. These cerebral motives continue to exercise their influence on neural development and behavior throughout life, transforming the behaviors of the developing individual through a succession of phases to which other individuals and cultural institutions are constrained to adapt. We discuss the theory of innate intersubjectivity and relate it to the hypothesis of an Innate Motive Formation that emerges in brain development as regulator of morphogenesis in neural systems, and that continues to function, postnatally, as generator of motives and emotions by which human contacts and relationships are regulated. We suggest that differentiates of the primary motive formation in the embryo brain later serve to generate intelligent exploration of the objective environment and the emergence of an additional dialogic mechanism that represents the self-subject as a partner for an other-subject, intersubjectively. Intersubjective communication in infancy leads, through systematic age-related transformations of the brain and behavior, to preverbal mimetic negotiation of cooperative awareness and joint task performance. Finally we discuss, in relation to this theory, interpretations of faulty communication and development at different stages of the life cycle that result from maternal postnatal depression, autism, premature birth and schizophrenia.

Foot biomechanics during walking and running.

OBJECTIVE: To describe the anatomy and biomechanics of the foot and to explain how movement and gait are integrated in the foot during walking and running. DESIGN: We review the anatomy and the biomechanical adaptations of the foot during walking and running. MATERIAL AND METHODS: Illustrations are presented to depict these biomechanics. RESULTS: The human foot is an intricate mechanism that cushions the body and adapts to uneven surfaces. It provides traction for movement, awareness of joint and body position for balance, and leverage for propulsion. CONCLUSION: With an understanding of the factors discussed herein, clinicians will have more knowledge to evaluate foot problems.

Lack of correlation between different measurements of proprioception in the knee.

Current methods of measurement of proprioceptive function depend on the ability to detect passive movement (kinaesthesia) or the awareness of joint position (joint position sense, JPS). However, reports of proprioceptive function in healthy and pathological joints are quite variable, which may be due to the different methods used. We have compared the validity of several frequently used methods to quantify proprioception. Thirty healthy subjects aged between 24 and 72 years underwent five established tests of proprioception. Two tests were used for the measurement of kinaesthesia (KT1 and KT2). Three tests were used for the measurement of JPS, a passive reproduction test (JPS1), a relative reproduction test (JPS2) and a visual estimation test (JPS3). There was no correlation between the tests for kinaesthesia and JPS or between the different JPS tests. There was, however, a significant correlation between the tests for kinaesthesia (r = 0.86). We conclude therefore that a subject with a given result in one test will not automatically obtain a similar result in another test for proprioception. Since they describe different functional proprioceptive attributes, proprioceptive ability cannot be inferred from independent tests of either kinaesthesia or JPS.

Understanding the incomprehensible: private theories of first-episode psychotic patients and their therapists.

Private theories about psychosis, its background, and cure were studied using narratives of first-time psychotic patients and their therapists. Both patients and their therapists were interviewed on three occasions over a period of 1 1/2 years. Three cases were chosen as dyads in point in order to highlight different relations between the patient's and the therapist's private theories, different patterns of recovery from psychosis, and different outcomes. The cases are contrasted by paired comparisons. The study indicates that an awareness and joint discussion of incompatibilities between the two participants' private theories might be a substantial contribution to the process of recovery from psychosis.
