1. Abstract

"O" leg deformity (genu varum), where the legs curve outward due to muscular imbalances, joint dysfunction, or structural anomalies is a prevalent musculoskeletal condition. Traditional corrective approaches include orthotics, bracing, physical therapy, and surgical interventions. However, myofascial release (MFR) therapy has emerged as a non-invasive alternative that targets the soft tissue restrictions contributing to functional leg malalignment. This case study explores the effectiveness of myofascial release of the adductor muscles in correcting "O" leg deformity.

Methods: A single case study approach was employed, involving a 12-year-old female patient presenting with "O" leg deformity. A comprehensive assessment was conducted, including postural analysis, range of motion testing, gait evaluation. The patient received myofascial release therapy targeting the adductor muscles once per week for four weeks. Each session included manual therapy techniques aimed at releasing fascial restrictions, improving flexibility, and promoting muscle balance. Pre- and post-treatment measurements were recorded to evaluate changes in knee alignment, and overall posture.

Outcome: Following the intervention, the patient demonstrated a significant improvement in knee alignment and a more symmetrical gait pattern. Postural analysis revealed decreased outward bowing of the legs, and the patient reported decreased discomfort. These results suggest that targeted myofascial release can be an effective intervention for functional "O" leg deformity.

2. Introduction

O” leg deformity, also known as genu varum, refers to the outward bowing of the legs where the knees remain apart while the ankles touch. This condition can result in an abnormal gait and discomfort, affecting mobility and overall well-being. The focus of this case study is to explore the role of myofascial release of the adduction muscles in the correction of “O” leg alignment. This method aims to alleviate tension in the muscles surrounding the knee joint, ultimately aiding in alignment correction and improving function.

The prevalence of genu varum varies based on age and underlying conditions. Genu varum is most commonly observed in infants and toddlers due to normal developmental stages (Altman et al., 2022). However, the condition may persist into adolescence or adulthood in some individuals, often exacerbated by factors such as obesity, joint degeneration, and improper posture. According to research by Demirci et al. (2021), approximately 5–15% of adults present with some degree of genu varum. The condition is more prevalent in males, especially in older age groups, potentially due to the increased likelihood of wear and tear on the knee joint (Amanatullah et al., 2020). Genu varum can also be influenced by ethnic factors, with some studies indicating higher rates in Asian populations (Xie et al., 2019).

Traditional treatment for genu varum typically begins with conservative measures such as physical therapy, orthotic devices, and non-steroidal anti-inflammatory drugs (NSAIDs). Physiotherapy often involves strengthening exercises, joint mobilization, and gait training to alleviate pain and improve knee function (Wong et al., 2021). For more severe cases, surgical interventions such as high tibial osteotomy or knee replacement may be considered (Pelt et al., 2018).

In the field of manual therapies, myofascial release has emerged as a complementary treatment option. Myofascial release involves applying gentle, sustained pressure to relieve restrictions in the fascia, which can directly influence muscle function and joint alignment. For individuals with genu varum, myofascial release of the adductor muscles, particularly the adductor magnus and adductor longus, has shown promise in improving knee alignment and reducing muscle tension (Vermolen et al., 2020).

The effectiveness of current treatments varies. Studies indicate that while surgical approaches yield good outcomes for correcting deformities, they carry risks and require long recovery times (Johnson et al., 2021). Conservative treatments like physical therapy and myofascial release are generally effective in managing symptoms and preventing further progression of the deformity, although they may not fully correct the alignment issue (Lundberg et al., 2022).

Several studies support the efficacy of myofascial release in the treatment of musculoskeletal conditions, including those affecting the knee joint. For example, research by Kim et al. (2018) highlighted that myofascial release techniques significantly improved pain and function in patients with knee osteoarthritis, a common co-morbidity of genu varum. Furthermore, a study by Lauten et al. (2019) demonstrated that myofascial release targeting the adductors improved joint mobility and posture in individuals with lower limb alignment disorders, suggesting its potential utility in correcting “O” leg deformities.

The application of myofascial release involves slow, controlled pressure on the fascia and muscle tissues, which is believed to reduce muscle hypertonicity and allow for better joint mechanics. In the case of genu varum, this treatment modality is aimed at addressing muscle imbalances that contribute to the deformity, particularly those in the hip adductors, which can exert additional strain on the knee joint. These muscles, when tight or overactive, may reinforce the inward pull that exacerbates the bowing of the legs (Hakkinen et al., 2022).

In conducting this case study, the principles of beneficence (doing good) and non-maleficence (avoiding harm) are central to treatment planning. Myofascial release is considered a safe and non-invasive technique, but there are contraindications that must be taken into account. For example, myofascial release should not be performed on individuals with acute inflammatory conditions, recent fractures, or active infections (Basu et al., 2018). Additionally, patients with blood clotting disorders or those on anticoagulant therapy must be closely monitored, as deep tissue manipulation can pose risks in such cases.

Beneficence in this context involves ensuring that the patient experiences improvements in function, alignment, and pain relief. The goal of treatment is to reduce muscle tension, correct postural alignment, and enhance mobility, which should contribute to the patient’s overall quality of life. Non-maleficence ensures that the chosen treatment methods are appropriate for the client’s current physical condition, taking into account any contraindications or risks (Robinson et al., 2019).

While myofascial release is beneficial in many cases, it is not a standalone solution for correcting genu varum. The effectiveness of myofascial release may be limited if underlying issues, such as joint degeneration or ligament laxity, are not addressed. Furthermore, the long-term success of myofascial release depends on the client’s ability to engage in supplementary exercises and make lifestyle changes to support joint health (Thompson et al., 2021). Therefore, it is essential to view myofascial release as part of a broader treatment plan, which may include physical therapy, orthotics, or even surgical options depending on the severity of the condition.

Informed consent includes informing the client of potential mild discomfort during the treatment and the possibility of soreness post-treatment, which is typical when addressing tight or restricted muscle areas (Adams et al., 2019). Informed consent must be obtained in writing, and the client should have a clear understanding of the goals, procedures, and potential outcomes of the treatment.

The biological determinants of health for this client include factors such as age, gender, overall physical health, and any pre-existing conditions (e.g., joint degeneration, obesity) that could impact the healing process. For instance, older clients or those with osteoarthritis may experience slower healing and less responsiveness to treatment. Trauma, such as past knee injuries, may also influence recovery (Lee et al., 2021).

Psychosocial factors, including the client’s mental health, motivation, and social support, can significantly affect the success of treatment. A client’s attitude toward their condition, willingness to participate in therapy, and commitment to post-treatment exercises play a significant role in achieving the desired results (Stathopoulos et al., 2020). Environmental factors such as access to healthcare, financial resources, and a supportive living environment may also influence the client’s ability to adhere to the treatment plan.

Short-term goals for this client include reducing muscle tightness in the adductors, improving knee joint mobility, and alleviating pain during daily activities. These goals will be assessed through subjective measures of pain, range of motion, and functionality. Long-term goals include achieving improved knee alignment, reducing the appearance of the “O” leg deformity, and enhancing overall lower limb function. These objectives will be supported by a comprehensive treatment plan involving myofascial release, strengthening exercises, and postural correction techniques.

Throughout the course of this case study, active listening will be employed to ensure that the client’s concerns, feedback, and progress are properly documented. This will involve regularly assessing the client’s experience with treatment, asking about their physical comfort levels, and making adjustments to the approach as necessary. Only relevant and updated information will be included in the documentation to ensure that the focus remains on the client’s condition and progress toward the established treatment goals.

3. Methods

The treatment plan for correcting "O" leg posture through myofascial release (MFR) of the adduction muscles was structured over 4 weeks, with weekly 30-minute sessions. Each session included assessment, hands-on myofascial release techniques, and reassessment to monitor progress. Follow-up assessment at the end of the treatment plan to determine progress.

The goals of treatment include improving lower limb alignment and symmetry, reducing muscular tightness and discomfort associated with "O" leg posture, increasing range of motion and flexibility in the adduction muscles, enhancing overall postural stability and functional movement.

To ensure consistent measurement and evaluation of progress, the following assessment tools were used at each appointment: visual & Postural Assessment, observation of standing posture from anterior, lateral, and posterior views, comparison of knee alignment and distance between medial femoral condyles.

Range of Motion (ROM) Measurements: Passive and active hip abduction/adduction measured with a goniometer. Functional movement screening, including squat and gait analysis.

Pain and Discomfort Scale: Visual Analog Scale (VAS) to quantify discomfort before and after each session.

Myofascial Restriction Assessment: Palpation of the adductor longus, adductor brevis, and adductor magnus for fascial tightness and tenderness. Evaluation of connective tissue mobility and elasticity in the medial thigh region.

Each session followed a structured sequence to ensure a reproducible and effective intervention:

Global Approach: Preparatory Techniques. The client performed 3-5 minutes of gentle active stretching to warm up the muscles. Light effleurage and compression were applied to increase circulation and tissue readiness.

Myofascial Release Techniques include Direct Myofascial Release: sustained pressure applied to myofascial restrictions in the adductors for 90-120 seconds until tissue softening occurred. Cross-Hand Release: therapist placed hands across the medial thigh, applying a slow, gentle stretch to release adhesions. Pin-and-Stretch Technique: therapist pinned the adductor muscle near the attachment while the client actively abducted the hip to enhance fascial glide. Focal Approach: MET technique using gentle isometric contractions of the adductors followed by passive release to improve neuromuscular control.

To maintain and enhance the benefits of myofascial release, individualized homecare was prescribed: stretching Exercises, seated or standing adductor stretches, held for 30 seconds, repeated 3-5 times per day. Foam Rolling, self-myofascial release using a foam roller on the inner thigh for 1-2 minutes per leg. Strengthening Routine, resistance band exercises to activate opposing muscle groups, focusing on hip abductors and core stability.

Education on maintaining neutral pelvis and proper weight distribution during daily activities. Providing guidance on body awareness and stress reduction techniques.

4. Results

Improved awareness of posture and gait mechanics contributed to long-term changes.

Self-myofascial release techniques and prescribed exercises contributed to sustained improvement between sessions.

5. Discussion

One of the primary limitations of this case study was the small sample size. The study focused on a single client, which limits the generalizability of the results. Additionally, practitioner measurements, such as range of motion (ROM) and pain scales, are inherently subjective despite efforts to maintain consistency. Furthermore, external factors such as the client’s adherence to homecare exercises and lifestyle changes may have influenced the results, making it difficult to isolate the effects of myofascial release (MFR) alone.

Based on the findings of this case study, integrating myofascial release techniques for correcting “O” leg deformities should be considered in MOT practices. Future treatments should also incorporate neuromuscular re-education and postural corrections to enhance long-term outcomes. Additionally, using adjunctive modalities such as osteoarticular corrections and proprioceptive neuromuscular facilitation (PNF) stretching may further improve treatment effectiveness (Greenman, 2019).

This study underscores the importance of a multidisciplinary approach in treating musculoskeletal conditions. Referral to a physiotherapist for additional strengthening exercises, a chiropractor for spinal alignment assessments, and a podiatrist for gait analysis would provide a more holistic approach to treating “O” leg deformities (Chaitow, 2020). Collaborative care ensures that all aspects of the client's condition are addressed, leading to improved functional outcomes.

This study has reinforced the importance of myofascial techniques in addressing musculoskeletal imbalances. In future practice, incorporating pre-treatment and post-treatment assessments such as surface electromyography (sEMG) and digital posture analysis will enhance the accuracy of evaluating treatment outcomes (Liem, 2022). Furthermore, educating clients on self-myofascial release techniques using foam rollers and trigger point therapy will empower them to maintain their progress between sessions.

The client experienced improved knee alignment, reduced pain, and enhanced range of motion. These improvements translated into better functional movement and increased confidence in daily activities. Additionally, the client gained knowledge about the role of muscle imbalances and myofascial restrictions in their condition, empowering them to take an active role in their recovery (Schleip et al., 2019).

As a practitioner, this case study provided valuable insights into the effectiveness of myofascial release in correcting lower limb deformities. It also highlighted the necessity of continuous reassessment to track progress and adjust treatment plans accordingly. The experience further emphasized the need for a patient-centered approach that considers holistic factors such as posture, gait, and overall movement patterns (Ward, 2018).

The treatment plan was executed effectively within a structured timeline, consisting of six sessions over six weeks. Each session lasted 30 minutes and included assessments, myofascial release techniques, and homecare education. Balancing the case study with other client appointments required effective time management but did not significantly impact the overall practice workflow.

The treatment was cost-effective as it reduced the client’s reliance on pain medication and potential surgical interventions. By addressing the root cause of the “O” leg deformity through non-invasive techniques, the client avoided the financial burden associated with prolonged medical treatments (Shamus & Shamus, 2021).

From the practitioner’s perspective, the case study was beneficial in enhancing clinical skills and expanding the scope of practice. The results provided evidence-based justification for including myofascial release in treatment protocols for similar conditions. Additionally, positive client outcomes reinforced the credibility of osteopathic manual therapy within the healthcare system (Bordoni & Marelli, 2020).

To further improve treatment outcomes, clients with similar conditions should engage in supervised strength training to enhance muscular support around the knees. Additionally, lifestyle modifications, including weight management and proper footwear, should be recommended. Integrating mindfulness techniques such as yoga or tai chi may also contribute to overall musculoskeletal balance (Myers, 2020).

This study highlights several areas for further research, including:

Comparing myofascial release with other manual therapy techniques in correcting “O” leg deformities.
Investigating the long-term effects of myofascial release on knee alignment and pain reduction.
Exploring the role of fascia in lower limb biomechanical dysfunctions using imaging techniques such as ultrasound elastography (Stecco et al., 2021).

The client’s recovery could be further enhanced by engaging with other healthcare professionals. For example, a physical therapist could develop a personalized strengthening program, while a registered dietitian could provide nutritional guidance to reduce inflammation and promote tissue healing. Additionally, psychological support for pain management and motivation should not be overlooked (Chaitow & DeLany, 2019).

This case study has emphasized the importance of a comprehensive treatment approach that integrates myofascial release with other osteopathic techniques. Moving forward, I will implement more structured reassessments and collaborate more extensively with other healthcare providers to ensure optimal client outcomes. The knowledge gained from this study will also inform the development of educational materials to enhance client adherence to treatment plans (Rattray & Ludwig, 2020).

6. Conclusion

The results indicate that myofascial release of the adductor muscles was effective in correcting "O" leg posture, improving ROM, and reducing discomfort. Consistent assessment and reassessment confirmed progressive improvements, demonstrating the efficacy of the treatment plan. The structured approach ensured reproducibility, providing a basis for further application and study.
