Understanding the Recovery Journey
Basal joint surgery, also called thumb carpometacarpal (CMC) arthroplasty, may be considered when pain and loss of function persist despite nonsurgical care. The procedure aims to ease pain and improve thumb use, but the approach depends on the joint and the patient’s needs, as described in the American Academy of Orthopaedic Surgeons’ overview of CMC arthroplasty.
Recovery generally moves from protecting the thumb to restoring motion, then gradually rebuilding strength. A therapy plan should match the operation and healing progress; hand therapy guidance after trapeziectomy advises patients to do only exercises recommended by their therapist.
There is no single timeline that fits everyone. Procedure, individual healing, and the surgeon’s instructions all shape when activities can resume. Dr. Rebecca S. Yu, MD, specializes in hand and upper-extremity surgery, and her basal joint arthritis care includes information about treatment options.
Why Surgery May Be Considered
What can cause pain at the base of the thumb?
Pain at the thumb’s base can come from osteoarthritis of the carpometacarpal (CMC), or basal, joint. As the protective cartilage wears down where the thumb metacarpal meets the trapezium, pinching and gripping may become painful. An injury, such as a fracture, can also cause pain or contribute to later arthritis. Swelling, stiffness, weakness, and reduced movement may occur as well. The American Academy of Orthopaedic Surgeons’ overview of CMC arthroplasty describes how this joint damage can affect grasping and pinching.
Can thumb arthritis improve without surgery?
Worn cartilage generally does not grow back, but symptoms may ease with changes to painful activities, a brace or splint, hand therapy, and appropriate medication. A clinician may also consider a corticosteroid injection. These approaches can help with pain and function without restoring the cartilage. At her Berkeley practice, Dr. Rebecca S. Yu describes a minimally invasive basal-joint procedure that cleans out the joint and may add a cushion to reduce pain and improve function; whether it is suitable depends on the individual evaluation.
When is surgery considered?
Surgery may be considered when pain and difficulty using the thumb continue despite nonsurgical care. The choice depends on the extent of joint damage, symptoms, and activity needs. Options range from ligament reconstruction in some cases of early joint looseness to procedures that remove damaged joint surfaces for more advanced arthritis. A hand specialist can assess the joint and discuss which treatments fit a patient’s goals; the Arthritis Foundation’s guide to thumb arthritis surgeries outlines how options vary by disease and patient needs.
Choosing a Surgical Approach
The right operation depends on how much cartilage and joint structure remain, the source of symptoms, and what the patient hopes to do with the hand. Dr. Rebecca S. Yu, MD, evaluates hand and upper-extremity conditions and discusses treatment options in the context of each patient’s needs.
For early arthritis linked to looseness in the joint, ligament reconstruction may help stabilize the thumb. With more advanced damage, a surgeon may remove all or part of the trapezium. One common approach, ligament reconstruction and tendon interposition (LRTI), uses tendon tissue to support the thumb and fill the space; other techniques use a different support or leave the space without tendon reconstruction. Selected patients may be candidates for an implant or joint fusion, which joins bones and limits motion.
Each option involves trade-offs. Fusion can create a stable joint but removes motion, while reconstruction aims to preserve movement and improve function. CMC arthroplasty is commonly performed as an outpatient procedure and generally takes about 30 to 60 minutes, though additional treatment or a different technique can change the operating time. AAOS guidance on thumb CMC arthroplasty describes the procedure and factors that influence planning.
The goal is to ease pain and make pinching and gripping more comfortable, but outcomes differ. Some people continue to have discomfort or stiffness, or notice reduced pinch strength. Dr. Yu’s basal joint arthritis care includes information about treatment options; a hand surgeon can weigh likely benefits and limitations against imaging, symptoms, and daily activities.
The First Weeks After Surgery
After thumb CMC surgery, most patients go home the same day with the hand protected in a bulky dressing, cast, or thumb-spica splint. Swelling, bruising, and discomfort are common, especially during the first few days. Keeping the hand elevated and taking medication as directed can help. If regional anesthesia was used, pain may become more noticeable as the numbing medicine wears off.
An early follow-up, often within one to two weeks, gives the surgeon a chance to check the incision and healing, remove stitches if needed, and adjust the dressing or splint. The initial splint may then be replaced with a removable one, or protection may continue in a cast, depending on the procedure and healing. Thumb and wrist protection commonly lasts about four to six weeks, but the schedule varies. The AAOS guide to thumb CMC arthroplasty describes a range of postoperative splinting and therapy plans.
Until the surgeon or hand therapist clears more activity, avoid lifting, forceful gripping or pinching, and pressure on the operated hand. Keep the splint or cast in place and follow instructions about keeping it dry. Dr. Rebecca S. Yu, MD, a board-certified hand and upper-extremity surgeon in Berkeley, provides information about basal joint arthritis treatment and individualized care.
Wait to drive until the hand is no longer numb or immobilized, medication does not affect alertness, and you can control the vehicle safely without significant pain. Ask your surgeon when driving is appropriate for your operation and recovery. Contact the surgical team if pain is severe, worsening, or not responding to the recommended treatment.
Therapy and Gradual Return to Use
Therapy starts when the surgeon considers the repair ready for movement. After thumb CMC arthroplasty, the hand is usually protected at first, and gentle motion may begin after the initial healing period. Depending on the procedure and recovery, therapy may continue for several weeks to a few months.
When can I start exercises after thumb surgery, and what exercises may be recommended?
Your surgeon or hand therapist will decide when it is safe to begin. Early exercises may focus on moving the fingers and wrist to limit stiffness. The therapist may then add gentle thumb bending and straightening, moving the thumb away from the palm, and touching the thumb to each fingertip. Strengthening and pinch or grasp activities come later, when healing allows. The North Tees and Hartlepool NHS hand-therapy guidance stresses following the therapist’s recommended exercises and progressing them only when advised.
Do not start exercises or increase their difficulty on your own, and never force the thumb. Stop and contact your care team if an exercise causes sharp or worsening pain. Rebecca S. Yu, MD, provides hand and upper-extremity care in Berkeley, including evaluation and treatment planning for hand conditions; exercise timing should be guided by the treating surgeon and therapist.
How long might occupational or physical therapy continue after thumb surgery?
Therapy often begins once the initial protection period has passed, commonly within several weeks of surgery. Early sessions focus on restoring motion and preventing stiffness. As healing progresses, a therapist may introduce strengthening and activities that reflect everyday hand use. The schedule varies with the operation, healing, and personal goals.
How long does recovery take after thumb CMC arthroplasty, including LRTI or tendon-transfer procedures?
Light daily activities may return gradually over the next few months, but this does not mean the thumb is ready for every task. Strength and comfortable use can continue to improve for six to twelve months. Recovery after ligament reconstruction and tendon interposition (LRTI) or another tendon-transfer procedure is also gradual. The American Academy of Orthopaedic Surgeons’ CMC arthroplasty guidance notes that some patients remain protected longer before therapy begins, underscoring why your own surgeon’s plan should take priority.
Recovery Is Individual
Recovery after thumb CMC surgery is gradual, and published timelines describe general patterns, not promises. Even within a single procedure, healing and readiness to resume activities can differ.
Follow the plan set by your surgeon and hand therapist, who can adjust guidance to your operation and progress. If symptoms change or you are unsure whether an activity is safe, ask your care team before proceeding. AAOS also advises patients to seek guidance specific to their circumstances in its CMC arthroplasty information.
