Chronic Ankle Instability in Kathmandu: From First Sprain to Lasting Stability

<p>Chronic ankle instability refers to recurrent giving way, perceived insecurity, and repeated sprains after an initial lateral ankle sprain. Up to one-third of people who sustain a lateral sprain report ongoing instability, particularly when early rehabilitation is incomplete. Because the lateral ligament complex and the neural pathways that sense joint position heal together, incomplete healing of both can leave the ankle vulnerable. In Kathmandu where uneven pavements, stairways, and trail terrain are common, residual instability often declares itself months after the original injury. Dr. Bodh Raj Gautam (NMC 23071, MBBS KU, MS Orthopedics) evaluates instability by mechanism, mechanical laxity, and sensorimotor control rather than by a single sprain episode.</p> <h2>Why ankles keep giving way</h2> <p>The anterior talofibular ligament and calcaneofibular ligament resist inversion and internal rotation. A typical sprain is an inversion-internal rotation injury with the foot plantarflexed, often while landing or stepping on an uneven edge. With a severe sprain the ligaments may heal in a lengthened position, and the peroneal muscles and joint mechanoreceptors that correct sudden inversion lose speed and accuracy. Systematic reviews distinguish mechanical instability (ligament laxity demonstrable on stress testing) from functional instability (proprioceptive and neuromuscular deficits despite adequate healing), though many patients have both. Contributing factors include inadequate time in protection, persistent swelling that inhibits muscle activation, high Beighton laxity, prior contralateral sprain, and footwear with a narrow base or worn lateral heel that promotes supination.</p> <h2>Clinical assessment that changes management</h2> <p>History details first sprain severity, time to weight-bearing, rehabilitation completed, episodes of giving way with activity type, swelling pattern, and ability to run or cut. Examination includes localized tenderness, swelling, range of motion, anterior drawer and talar tilt testing for ligament laxity, peroneal strength, single-leg balance with eyes open and closed, and gait. Alignment of the hindfoot into varus increases lateral load and is documented. Routine radiographs are obtained after acute injury to exclude fracture; for chronic instability, weight-bearing ankle views assess alignment and osteochondral lesions. Stress radiographs or ultrasound may quantify laxity when surgical planning is considered, while MRI is selective to evaluate cartilage, peroneal tendon pathology, or syndesmotic injury when pain or swelling remains atypical.</p> <h2>Rebuilding stability with evidence-based rehabilitation</h2> <p>First-line care for chronic ankle instability without severe mechanical laxity or cartilage lesion is structured rehabilitation. High-quality trials and clinical guidelines converge on several components:</p> <ul> <li>Protection and swelling control after acute sprains, then progressive loading through range of motion and ankle dorsiflexion work to prevent stiffness.</li> <li>Peroneal and hip abductor strengthening, intrinsic foot muscle work, and calf flexibility. Ankle evertor endurance correlates with functional stability more than maximal strength alone.</li> <li>Neuromuscular training: single-leg balance, wobble board, band-resisted inversion-eversion, and hop and cutting drills with emphasis on hip and trunk control. Balance training reduces recurrence by up to half in secondary prevention studies.</li> <li>Footwear and bracing: during return to sport, a lace-up brace or taping can improve confidence and reduce recurrence while neuromuscular control is rebuilt. Choice between brace and tape is individualized by sport, hygiene, and skin tolerance.</li> </ul> <p>Duration matters. A program of at least 6 to 8 weeks with home practice three times per week, followed by maintenance during sport participation for several months, produces more durable gains than a brief clinic course alone. Running progression begins only when pain-free single-leg hop and balance criteria are met, then advances on firm even ground before trail or court work.</p> <h2>Bracing choices, footwear, and maintaining gains during sport</h2> <p>Choosing between taping, lace-up braces, and no support after rehabilitation depends on sport, sweat and hygiene, and confidence. Tape offers close contour fit but loosens with Perspiration and requires application skill, while lace-up braces provide consistent support over a season with less daily time cost and allow adjustment as swelling fluctuates. Studies show both can reduce recurrence during the return-to-play window when combined with neuromuscular training, but neither substitutes for strength and balance work. Footwear influences stability more than many athletes expect. A shoe with adequate heel width and torsional stiffness supports the hindfoot, while a worn lateral heel bevel or overly narrow sole increases supination moment. On uneven Kathmandu terrain, a higher collar or trail shoe may add confidence for hill or off-road running, whereas an indoor court shoe prioritizes lateral stability.</p> <p>Maintaining gains requires integration into normal training rather than stopping exercises at discharge. A maintenance set two to three times weekly with single-leg balance eyes closed, band-resisted eversion, and hop and landing drills preserves sensorimotor control into subsequent seasons. Ankle taping education for athletes who prefer it, and criteria for when to retape or rebbrace, are reviewed so support is available for tournaments or long hill days without creating perpetual dependence. At follow-up visits Dr. Gautam reassesses peroneal endurance, anterior drawer laxity, single-leg hop distance symmetry, and hours of brace use versus hours of sport, adjusting footwear and surface selection collaboratively. Early reporting of a new sprain while still in training allows prompt protection and prevents the repeated swelling-reinjury cycle that lengthens instability duration. This care model emphasizes transparency about benefits and limits, and remains educational.</p> <h2>When referral or surgery is considered</h2> <p>Persistent giving way despite compliant rehabilitation, demonstrable mechanical laxity with positive anterior drawer under anesthesia or on stress imaging, or concomitant osteochondral talar lesion may prompt surgical discussion. Lateral ligament repair, often the modified Brostrom-Gould procedure, imbricates and reinforces the attenuated ligaments with the inferior extensor retinaculum. Tendon augmentation or reconstruction is considered with poor tissue quality or generalized laxity. Arthroscopy at the same setting addresses intra-articular bodies or cartilage injury when MRI or mechanical symptoms support it. Postoperative rehabilitation is staged with initial immobilization, then progressive weight-bearing, range of motion, and neuromuscular training over roughly 3 to 6 months before pivoting sports. Expected outcomes are high for stability and function when indications and tissue quality are matched, though stiffness, numbness over the lateral foot, and residual swelling are counseled risks. Dr. Gautam tracks instability episodes per month, balance time, and hop performance at follow-up to determine progression, and coordinates bracing and surface choices with coaches and physiotherapists.
