Contractures are treated with a combination of stretching, splinting, and sometimes injections or surgery, depending on how severe and long-standing the tightness is. Mild contractures caught early often respond well to consistent physical therapy alone, while fixed, rigid contractures may need surgical release. The key factor in choosing a treatment is whether the joint can still be moved passively by an examiner or whether the tissue has stiffened beyond what stretching can reverse.
Why Contractures Happen
A contracture forms when the soft tissue around a joint shortens and stiffens from lack of movement. This can happen after a fracture that keeps your arm in a cast, a stroke that leaves muscles in constant spasm, a burn that produces thick scar tissue, or simply prolonged bed rest. The underlying process is the same regardless of cause: collagen fibers in the connective tissue around the joint develop extra chemical bonds called cross-links. In animal studies, nine weeks of immobilization produced a significant increase in these cross-links even though the total amount of collagen stayed roughly the same. It’s not that your body builds more tissue. The existing tissue locks itself into a shorter, stiffer configuration because it isn’t being moved.
Over time, these changes progress from the muscles and tendons into the joint capsule itself. Early contractures are largely muscular and respond to stretching. Once the capsule, ligaments, and cartilage are involved, treatment becomes more difficult and more invasive.
Stretching and Physical Therapy
Consistent, gentle stretching is the foundation of contracture treatment at every stage. The general principle is low force applied for a long time, rather than aggressive short bursts. Forcing a stiff joint through its range quickly can cause microtears, pain, and inflammation that actually worsens the problem.
For people who are immobilized or at risk, passive range-of-motion exercises (where a therapist or caregiver moves the joint for you) are standard. Cleveland Clinic guidelines recommend 10 repetitions of each movement, performed two to three times per day. This is the minimum to maintain joint mobility and prevent new contractures from forming in patients who can’t move on their own.
For established contractures, therapists typically use prolonged positioning or sustained stretches held for minutes at a time, often combined with heat to make the tissue more pliable. The goal is to gradually lengthen the shortened tissue without triggering a protective muscle spasm. Progress is measured in small increments, sometimes just a few degrees of improved range per week.
Splinting and Orthotic Devices
Splints work by holding a joint at the end of its available range for extended periods, applying a slow, constant stretch that remodels the stiffened tissue over time. There are two main types. Static splints hold the joint in one position and are periodically adjusted as range improves. Dynamic or static-progressive splints use springs, rubber bands, or adjustable hinges to apply a gentle ongoing force.
Wear time matters significantly. A study on hand contractures found that wearing a splint 6 to 12 hours per day produced statistically better results than wearing it fewer than 6 hours. Many treatment plans call for overnight wear plus additional hours during the day to hit that threshold. Your therapist will typically remold or adjust the splint every one to two weeks as the joint gains range.
Serial casting is a related approach often used for ankle or knee contractures. A cast holds the joint at its maximum stretch for several days, then it’s removed, the joint is stretched further, and a new cast is applied at the new position. This cycle repeats until the desired range is achieved.
Injections for Spasticity-Related Contractures
When a contracture is driven by constant muscle tightness from a neurological condition (such as stroke, cerebral palsy, or traumatic brain injury), botulinum toxin injections can relax the overactive muscles enough to make stretching and splinting effective. The toxin blocks the nerve signal that keeps the muscle contracted, providing a window of reduced tone that typically lasts three to four months.
Treatment goals in spasticity shift toward pain reduction, preventing contractures from worsening, and making physical therapy possible. The injections don’t fix the contracture on their own. They lower the resistance so that stretching, splinting, and functional exercises can do their work during the months of reduced muscle tone. Repeat injections are common, timed to maintain that therapeutic window.
Treating Dupuytren’s Contracture in the Hand
Dupuytren’s disease is a specific type of contracture where a thick cord of tissue forms in the palm and gradually pulls one or more fingers into a bent position. It has its own treatment pathway because the problem is in the connective tissue of the palm rather than in the joint or muscles.
For mild cases, an enzyme injection can dissolve the cord without surgery. In a trial published in the New England Journal of Medicine, collagenase injections reduced contracture by about 79% within 30 days of the last injection, compared to roughly 9% in patients who received a placebo. Among joints in the knuckle area, 92% improved enough that they no longer met the threshold for surgical intervention. The procedure involves one or two injections followed by a manipulation the next day, where the doctor straightens the finger to snap the weakened cord. Recovery is faster than surgery, though contractures can recur over time.
For more advanced Dupuytren’s or recurrent cases, surgery to remove the diseased tissue remains the most durable option, though it involves a longer recovery period and hand therapy afterward.
Burn Scar Contractures
Burns create a distinct type of contracture. As a deep burn heals, scar tissue forms that is shorter and less elastic than normal skin. Because scar tissue doesn’t grow proportionally as the body moves and ages, the contracture can worsen over time, especially in children.
Mild burn contractures are managed with compression garments, silicone gel sheets, and aggressive stretching started as early as possible during healing. Splinting the affected area in a stretched position overnight helps counter the pull of the scar during sleep.
When scar contractures are severe enough to limit function, surgical reconstruction is necessary. Surgeons use techniques that rearrange local skin flaps to lengthen the scar line. The most common approach involves cutting the scar in a zigzag pattern and transposing the resulting triangular flaps, which effectively converts a straight, tight band into a longer, more flexible line. The specific pattern (using 45- or 60-degree angles, single or multiple flaps) depends on the scar’s location and severity. For very large contractures, skin grafts may be needed. After surgery, compression garments and silicone gel application are standard to reduce the chance of the scar tightening again.
When Surgery Is Needed
Surgery becomes the primary option when a contracture is rigid, meaning the joint cannot be straightened even with steady manual pressure. At that point, the joint capsule, tendons, or both have shortened permanently, and no amount of stretching will restore full motion.
The type of surgery depends on what structure is causing the restriction. A tendon release (tenotomy) cuts or lengthens a shortened tendon. A capsular release cuts into the thickened joint capsule to restore movement. Often both are needed together. In a cadaveric study of rigid toe contractures averaging about 57 degrees of fixed bending, tendon release alone improved the contracture by roughly 47%. Adding a capsular release restored full mobility in 92% of the remaining cases. These numbers illustrate a common principle: rigid contractures usually involve multiple layers of tissue, and addressing only one layer gives incomplete results.
After surgical release, the work isn’t over. Without aggressive post-operative stretching, splinting, and therapy, the tissue will scar down and tighten again. Most surgeons prescribe a structured rehabilitation program starting within days of the procedure.
Factors That Affect Your Outcome
How well a contracture responds to treatment depends on several things. Duration matters most. A contracture that developed over weeks responds far better than one that has been present for years, because long-standing contractures involve deeper structural changes in the joint capsule and cartilage. The underlying cause also plays a role: a contracture from temporary immobilization after a fracture has a better prognosis than one driven by ongoing spasticity from a neurological condition, because the spasticity keeps pulling the joint back into the shortened position.
Age, nutrition, and the specific joint involved all factor in as well. Larger joints like the knee and elbow tend to respond better to stretching and splinting than small finger joints. Regardless of the treatment approach, consistency is the single biggest predictor of success. Contracture treatment is slow, often requiring weeks to months of daily work for meaningful gains, and skipping sessions allows the tissue to tighten back toward its shortened state.
